1 Thu Nov 14 19:27:30 1991 Fred Fish (fnf at cygnus.com)
3 * symfile.c: Add function compact_misc_function_vector() to
4 remove duplicate misc function vector entries. See comments
5 in source for why this is necessary/desirable.
7 * dwarfread.c: Add misc function type parameter to internal
8 record_misc_function(). Remove calls to init_misc_bunches()
9 and condense_misc_bunches(), these are now done in elfread.c.
11 * elfread.c: Add support for reading bfd canonical symbol tables
12 and generating misc function vector entries for global and
13 absolute symbols. Do calls to init_misc_bunches() and
14 condense_misc_bunches() where they will enclose all calls to
15 record_misc_function(), including those in dwarfread.c.
17 Thu Nov 14 17:02:11 1991 Roland H. Pesch (pesch at cygnus.com)
19 * doc/Makefile.in: new targets gdb.me, gdb.ms, gdb.mm

38 Motorola 88000 port without tears, I mean without tdescs.
40 * m88k-tdep.c: Blow away all tdesc stuff.
41 Provide functions for all the frame-related macros in
42 tm-delta88.h. Adopt i960-style EXTRA_FRAME_INFO.
43 (examine_prologue, frame_find_saved_regs, skip_prologue): borrow
44 from i960-tdep.c and adapt to the function prologues on the 88k.
45 (read_next_frame_reg): Borrow from mips-tdep.c.
46 FIXME: frame_locals_address should go away.
48 * tm-delta88.h: Dump all the tdesc stuff.
49 Macros for all frame-related stuff call fns of same name.
50 Remove duplicated definitions. FP_REGNUM becomes same as
53 * xm-88k.h: Eliminate lots of library dependencies, now handled
54 in libiberty. Eliminate KDB nonsupport.

65 * alloca.c, language.c, tdesc.c: Lint.
66 * tdesc.c, tdesc-lib: FIXME: remove these.
68 Tue Nov 12 19:30:22 1991 John Gilmore (gnu at cygnus.com)

77 Allow setting breakpoints on C++ destructors.
78 * valops.c (destructor_name_p): Don't check TYPE_HAS_DESTRUCTOR,

80 * symtab.c (decode_line_1): For example (see above), here.
81 * buildsym.c, symtab.h: Remove TYPE_FLAGS_HAS{CON,DE}STRUCTOR
82 flags since they are no longer used.
84 Fixes to support C++ methods with functional parameters.
85 * c-exp.y (func_mod rule): Allow (and ignore) list of parameter
86 types in a function type.
87 * eval.c (parse_and_eval_type), value.h: New function,
88 parse_and_eval_type, is based on old code from check_stub_method.
89 But don't actually evaluate the cast, since that calls
90 value_cast(), whcih may fail. Just extract the type
91 from the parsed expression.
92 * values.c (check_stub_method): While looping through the
93 arguments, adjust depth *after* parameter has been handled.
94 Replace call and setup of parse_and_eval with new function
97 Tue Nov 12 09:40:07 1991 Fred Fish (fnf at cygnus.com)

104 m88k-xdep.c, main.c, printcmd.c, pyr-xdep.c, source.c,
105 sun386-xdep.c, symm-xdep.c, umax-xdep.c, values.c, xcoffread.c:
106 Change all instances of use of fixed args concat() to variable
107 args concat() now located in libiberty.
109 Tue Nov 12 07:23:46 1991 John Gilmore (gnu at cygnus.com)
111 * Makefile.in: Add xcoffread.c, xcoffexec.c.
112 * xcoffread.c: New file for handling AIX mangled-coff files.

137 whenever it is not supplied by coredep.c
139 Sat Nov 9 00:40:32 1991 John Gilmore (gnu at cygnus.com)
141 Add tracking of object files (that contain symbols) to gdb.
142 This includes a "struct objfile" that owns symtabs and psymtabs
143 that were read in from that binary file.
145 * symfile.h: Add struct objfile. Add pointer to the objfile
146 into the struct sym_fns.
147 Replace global `symfile' and `symfile_mtime' with
148 `symfile_objfile'. Add global object_files chain.
150 * symfile.c: Move param.h above symtab.h.
151 (sort_misc_function_vector): Add.
152 (syms_from_objfile): Was syms_from_bfd.
153 (symfile_open): Now returns objfile.
154 (allocate_objfile): New.
155 (free_objfile): New, replacing free_all_.*symtabs.
156 (symfile_init): Takes objfile arg, puts it in sym_fns result.

158 (allocate_symtab): Takes objfile as new parameter, chains them.
159 Handle INIT_EXTRA_SYMTAB_INFO.

162 * dbxread.c: Make more errors into complaints.
163 (push_subfile, pop_subfile): Move to buildsym.c.
164 (dbx_symfile_read, dbx_symfile_init, fill_symbuf, read_dbx_symtab,
165 start_psymtab, psymtab_to_symtab_1, read_ofile_symtab,
166 dbx_psymtab_to_symtab, ): Use bfd ops, don't use file descriptor.
167 Pass objfile. Change callers.
168 (fill_symbuf, SWAP_SYMBOL): Take bfd as arg.
169 (read_dbx_symtab): Just wipe out new symbols, not all, on error.
170 (end_psymtab): Blow away psymtab if empty.

176 (dbx_lookup_type): Handle null typevector.
177 (dbx_alloc_type): Check file number, not sym number, for -1.
178 (find_symbol_in_list): Add for xcoffread.
179 (start_symtab): Default typevector is empty. Keep reusing same
181 (end_symtab): Take objfile argument and pass it to
182 allocate_symtab. Don't make a symtab if no blocks or symbols.
183 Handle empty typevector.
184 (push_context): New function for context stack nesting.
185 (read_type): Mark FIXME where we need to reintroduce type smashing.
187 * buildsym.h (pop_context): Macro, paired with push_context.
188 (subfile_stack): Move here from dbxread.c.
190 * coffread.c (end_symtab, read_coff_symtab): Take and use objfile arg.
191 (read_coff_symtab): Cleanup by freeing objfile, not all symtabs.

196 * dwarfread.c (scan_compilation_units, start_psymtab,
197 process_dies, end_symtab, dwarf_build_psymtabs,
198 read_lexical_block_scope, read_func_scope, read_file_scope): Take
199 and use objfile argument.
200 (psymtab_to_symtab_1, read_ofile_symtab): Don't take or use file
201 descriptor. Use BFD internal functions instead.
202 (end_symtab): Call global allocate_symtab.
204 * elfread.c, target.c: Minor changes to accommodate objfiles.
205 * symtab.h: partial_symbol_table has no symfile_name member now.

207 (struct symtab): Add objfile * and objfile_chain * of symtabs.
208 (struct partial_symtab): Add objfile * and objfile_chain * of
209 psymtabs. Remove symfile_name.

225 * inflow.c (new_tty): Use USE_O_NOCTTY #define.
226 * language.c, printcmd.c (print_scalar_formatted), signame.c,
229 Thu Nov 7 18:26:15 1991 Steve Chamberlain (sac at rtl.cygnus.com)
231 * Makefile.in: link with libiberty after libreadline, since
232 readline might want something in libiberty.
233 * m88k-xdep.c: Fixed the register offsets in the ptrace_user
234 struct for BCS 88k machines.
235 * xm-m88k.h: don't define USIZE if already defined.
236 * configure.in: Added delta88 target.
238 Thu Nov 7 04:51:19 1991 John Gilmore (gnu at cygnus.com)
240 * am29k-pinsn.c, am29k-opcode.h: Fix decoding of mtacc, dmac, fmac.
242 * tm-*.h: Remove READ_DBX_FORMAT, COFF_FORMAT, and
243 READ_MIPS_FORMAT, which have been unused since BFD. Still
244 remaining is COFF_NO_LONG_FILE_NAMES.
245 * tm-sun3.h, tm-altos.h: Remove detritus accidentally left from
246 function calling code moved to m68k-tdep.c.
248 Wed Nov 6 17:21:59 1991 John Gilmore (gnu at cygnus.com)
250 * coffread.c: Eliminate c_nsyms in favor of c_naux.
251 Complain if no auxents on .bf and .ef FCN symbols, and assume
252 lots of line numbers.
253 (init_linenos, enter_linenos): Use a sentinel at the end of the
254 read-in linenos, to make for a fast, safe loop-end test.
256 Wed Nov 6 02:54:08 1991 Steve Chamberlain (sac at cygnus.com)
258 * coffread.c (read_coff_symtab): coffread used to rely on the
259 x_sym.x_misc.x_lnsz.x_lnno field giving the # of linnos in a
260 function. Two of the formats I'm using (29k and 88k) don't seem to
261 set it. Ths patch to fcn_last_line and (enter_linenos) is an
262 attempt to use the actual size of the linno table in the file to set
263 the number of linenos to process.
265 Tue Nov 5 22:47:46 1991 Steve Chamberlain (sac at cygnus.com)
267 * Makefile.in: put a - infront of the mv y.tab.c c-exp.tab.c and
268 mv y.tab.c m2-exp.tab.c, so that if bison is used, and the files
269 are created in place, so the mv fails, then the make continues.
271 Tue Nov 5 16:47:47 1991 Per Bothner (bothner at cygnus.com)
273 Add C++ as a separate language.
274 * defs.h (enum language): Add language_cplus.
275 * dwarfread.c (end_symtab): Support language_cplus.
276 * c-exp.y: Add new struct language_defn cplus_language_defn.
277 Don't set c to be the default language (see main.c).
278 * c-exp.y (yylex): Only look for field of this if
279 language is C++. (First difference from C!)
280 * language.c: Add case branches for C++ (currently, all
281 the same as C). Also, add c++ to "usage" note for "set lang".
282 * valprint.c (typedef_print). Add case branches for C++.
283 * main.c (main): New way to set initial language: Look at
284 file extension of psymtab containing main(). (Same as we
285 do for symtabs, but avoid loading the symtab yet.)
286 * symtab.c: New routine find_main_psymtab(), used by main()
287 to set initial language.
288 * symfile.c (allocate_symtab): Move code for mapping file
289 extensions-> languages to new deduce_language_from_filename().
291 Fix a C++ problem when looking for methods in super-classes.
292 There was confusion between base and derived types.
293 * valops.c (value_fn_field): Change function interface.
294 * values.c: Use new value_fn_field interface.
296 Mon Nov 4 10:49:33 1991 Per Bothner (bothner at cygnus.com)
298 * infrun.c: Fixed typo in comment.
299 * utils.c: All the v*fprintf emulation is now in libiberty,
300 so we can get rid of some junk.
301 * xm-sun3os4.h, xm-sun4os4.h, xconfig/decstation, xconfig/i386sco,
302 xconfig/sun3os4, xconfig/sun4os4: Don`t need HAVE_STRSTR any more.
303 * m68k-pinsn.c (print_insn_arg): Support BB/BW/BL
304 type operands, as used by branch instructions.
305 * gmalloc.c: Fix prototype of memcpy.
306 * elfread.c: Comment out register_addr, since it conflicts
307 with the one in coredep.c.
308 * buildsym.h: Remove extern declarations of two functions
309 that are really static in buildsym.c.
310 * tm-mips.h: Add symbolic names for more registers.
311 * mips-xdep.c (store_inferior_registers): Use new register names.
312 * xm-mips.h: Simplify REGISTER_U_ADDR, since it is now
313 only used for core files, not ptrace. Therefore,
314 the KERNEL_U_ADDR hack is no longer needed.
315 The mapping to ptrace number is now in in mips-xdep.c.
316 * mips-xdep.c: Define REGISTER_PTRACE_ADDR (using the
317 mapping from the old REGISTER_U_ADDR), and use it
318 in {fetch,store}_inferior_registers.
319 * mipsread.c: Rename #include ecoff.h to new name coff-mips.h.
320 * mips-tdep.c (mips_push_dummy_frame, mips_pop_frame):
321 Save/restore FP regs correctly (?).
322 * dbxread.c: Remove duplicate define_symbol and type_synonym_name
323 (these had been previously moved to buildsym.c).
324 Hence, define_symbol becomes extern instead of static.
325 * buildsym.c (read_struct_type): Comment out bogus handling
326 of C++ operator methods. Minor hacking of reading of class
327 contexts. Make define_symbol non-static, so dbxread.c can call it.
329 Fri Nov 1 11:05:47 1991 John Gilmore (gnu at cygnus.com)
331 * mipsread.c (read_mips_symtab, read_the_mips_symtab): Use real
332 filename with error messages.
333 * stack.c (frame_select_command): Rename to select_frame_command
334 to avoid "fr" and "fra" having nonunique completions.
335 * symfile.c (sort_symtab_syms): Ignore sort of zero symtab *.
336 (symfile_init): Print file format name when unable to handle it.
337 (free_named_symtabs): Use BLOCKVECTOR rather than obsolete BLOCKLIST.
338 * symmisc.c (free_symtab): Only free linetable if nonzero.
339 * symtab.h: Remove obsolete BLOCKLIST macros.
341 Thu Oct 31 18:12:43 1991 Stu Grossman (grossman at cygnus.com)
343 * infrun.c (wait_for_inferior): another stepi/nexti fix. Ensure
344 that stop_step is 1 at bottom of main loop. I don't know why this
345 needs to be done, but it helps me sleep better at night.
347 Sun Oct 27 18:18:39 1991 Stu Grossman (grossman at cygnus.com)
349 * main.c (initialize_history): Read history after reading all
352 Sun Oct 27 14:09:25 1991 John Gilmore (gnu at cygnus.com)
354 * buildsym.c: Break out initial malloc sizes.
355 (record_line): Record directly in a subfile. Alloc on demand.
356 (compare_line_numbers): Add from xcoffread.c.
357 (end_symtab): New params say whether to sort pendings and
358 linetable. Patch block stabs if defined. Shrink linetable before
359 allocating the symtab.
360 * buildsym.h: Delete line_vector* and prev_line_number. Add
361 global_stabs and file_stabs for xcoffread.
362 * dbxread.c (start_subfile): Move to buildsym. Change above calls.
363 * symtab.h: LINETABLE(symtab) can now be null. Zap LINELIST.
364 * symmisc.c, symtab.c: Cope with null LINETABLEs.
366 * blockframe.c: Pass fromleaf to INIT_EXTRA_FRAME_INFO.
367 * tm-29k.h, tm-88k.h, tm-i960.h, tm-irix3.h, tm-mips.h, tm-pyr.h,
368 tm-sparc.h: Accept fromleaf parameter.
369 * c-exp.y (yyerror): Pass error message if given.
370 * configure.in: Add rs6000 host and target.
371 * inflow.c (new_tty): O_NOCTTY kludge for RS/6000.
372 * symfile.h (entry_point): Add.
374 Sat Oct 26 00:16:32 1991 John Gilmore (gnu at cygus.com)
376 * buildsym.c: New file. Breaks out symbol-table-building routines
377 from dbxread.c, so they can be shared with xcoffread.c.
378 * buildsym.h: New file. Declarations for buildsym.c users.
379 * dbxread.c: Remove large chunks into buildsym.c.
380 * Makefile.in: Add buildsym.c and buildsym.h.
382 * symfile.c (syms_from_bfd): New routine.
383 (add_symbol_file): Call it to do the real work.
384 (syms_from_bfd): Initialize entry_point before calling symfile_init.
385 * symtab.h, symfile.c, coffread.c, mipsread.c, dwarfread.c:
386 Avoid declaring or setting entry_point (symfile.h & symfile.c cope).
388 Fri Oct 25 18:59:32 1991 Per Bothner (bothner at cygnus.com)
390 Various fixes to improve g++ debugging.
391 * symtab.h: Add is_const and is_volatile flags for each method.
392 These are bit fields - take their space from voffset,
393 which shrinks to 30 bits. Since voffset is now a bitfield,
394 make it unsigned for portability. This changes its interpretation
395 slightly: Static methods now have voffset 1 instead of -1,
396 and virtual offsets start at 2, not 1.
397 * symtab.c: Renamed gdb_mangle_typename to gdb_mangle_name,
398 since it now returns an entire magled method name, not just
399 the type part. This avoids some duplication.
400 It also allows us to correctly mangle const and volatile
401 methods (using the new is_const and is_volatile bit fields
403 * valprint.c (type_print_base), values.c (check_stub_method):
404 Simplify by using new gdb_mangle_name.
405 * values.c (value_headof): Fix to correctly handle single
406 inheritance (actually two fixes, either of which suffices).
407 * dbxread.c (read_struct_type): Handle const and volatile
409 * dbxread.c (read_struct_type): Yet one more place where
410 we must handle '\\' continuations.
411 * valprint.c (vtbl_ptr_name): Add final '\0'.
413 Fri Oct 25 16:06:38 1991 Stu Grossman (grossman at cygnus.com)
415 * tm-sparc.h, tm-68k.h (EXTRACT_RETURN_VALUE): fix output of
416 short return values for sparc and 68k. Patch from Paul Eggert.
418 * coffread.c, coredep.c, i386-xdep.c: install patches for
419 SysV/386 3.2 from Mauro DePalma.
421 Fri Oct 25 02:02:13 1991 John Gilmore (gnu at cygnus.com)
423 * core.c (core_file_info), exec.c (exec_file_info): Print file
424 type. Use printf_filtered.
426 * valops.c (value_fetch_lazy): Avoid 0-length fetches.
428 Thu Oct 24 23:06:40 1991 Fred Fish (fnf at cygnus.com)
430 * dwarfread.c: Add casts to remove compiler warnings.
432 * tm-3b1.h, tm-68k.h, tm-altos.h, tm-amix.h, tm-hp300bsd.h,
433 tm-hp300hpux.h, tm-isi.h, tm-news.h, tm-pn.h, tm-sun2.h,
434 tm-sun3.h: Remove locally duplicated code for calling functions
435 in the inferior. The only differences were in the specific trap
436 vectors used and whether or not an fpu was present. These are
437 now handled by appropriate definitions of BPT_VECTOR and
438 HAVE_68881 respectively. Other minor obvious cleanups.
440 * valops.c: Correct a minor misspelling.
442 * utils.c: Remove local BSD/USG hacks that are now in libiberty.
444 * dwarfread.c: Remove prototype for dwarfwarn. Does not work
447 Thu Oct 24 09:33:44 1991 John Gilmore (gnu at cygnus.com)
449 * stack.c (frame_command): Always print. Use new
450 frame_select_command to select a frame without printing.
452 * dwarfread.c: Use <varargs.h>, since <stdarg.h> is not portable.
454 Thu Oct 24 01:32:51 1991 Fred Fish (fnf at cygnus.com)
456 * dwarfread.c: New file for DWARF debugging format support.
458 * elfread.c: New file for ELF object file format support.
460 * procfs.c: New file for SVR4 /proc (process file system) support.
462 * tm-amix.h, xm-amix.h, tconfig/amix, xconfig/amix: New files for
465 * xm-svr4.h, tm-svr4.h: New files for SVR4 support.
467 * xm-m68k.h: New file for host machines with m68k cpu.
469 * Makefile.in: Add elfread.c and dwarfread.c to SFILES_MAINDIR.
470 Add elfread.o and dwarfread.o to OBS.
472 * symfile.h: Add "elf" to list of supported formats in comment.
474 * c-exp.y, defs.h, symtab.h, valprint.c: Add three new builtin
475 types to gdb, builtin_type_long_double, builtin_type_complex, and
476 builtin_type_double_complex. Add and use new TARGET_SHORT_BIT,
477 TARGET_INT_BIT, TARGET_LONG_BIT, TARGET_FLOAT_BIT,
478 TARGET_DOUBLE_BIT, TARGET_LONG_DOUBLE_BIT, TARGET_COMPLEX_BIT, and
479 TARGET_DOUBLE_COMPLEX_BIT, as the sizes in bits of the indicated
480 types on the target machine (ala the existing TARGET_LONG_LONG_BIT).
482 * infrun.c: When using SVR4 /proc interface instead of ptrace(),
483 call proc_set_exec_trap() to setup child to stop at first instruction.
485 * inftarg.c: When using SVR4 /proc interface, call proc_wait()
488 * m68k-tdep.c: Add new routines supply_gregset(), fill_gregset(),
489 supply_fpregset(), and fill_fpregset(), which are machine
490 dependent support routines for SVR4 /proc interface.
492 * utils.c: Add warning_setup() and warning(). Warning() behaves
493 the same as error() except that it returns normally rather than
494 jumping back to command level. Modules that don't want to call
495 warning() for some reason, but want to produce their own warnings,
496 can call warning_setup() to ensure compatibility with the way
497 warning() and error() deal with the terminal.
499 * symtab.c: Make internal errors produce more useful messages.
501 * tm-68k.h: Move code that is duplicated in almost every single
502 m68k based machine's configuration files to this common file.
503 Duplications in the configuration files still need to be removed
506 * infrun.c (child_create_inferior): System V versions must call
507 setpgrp() with no arguments, to comply with prototyping typically
510 * munch: Add support for SVR4 style nm output.
512 * dbxread.c, mipsread.c symmisc.c, symtab.c: Remove the object
513 file specific fields from the partial symbol table structure and
514 replace them with a pointer to private data for each different
515 flavor of object file reader to initialize appropriately.
517 Wed Oct 23 09:38:20 1991 John Gilmore (gnu at cygnus.com)
519 * xconfig/sun[34]os4: Add note about strstr botch on sunos4.0.3c
522 * mipsread.c (fixup_undef_type): New function. If a struct /
523 union / enum is defined in a header file but nowhere else used,
524 (by typedefing, pointer referencing or declaration) the mipsread code
525 builds the complete tree for the structure but leaves its code as
526 TYPE_CODE_UNDEF as it doesn't know what kind of aggregate it is.
527 Guess its type based on the details of the members.
529 Tue Oct 22 18:04:32 1991 Stu Grossman (grossman at cygnus.com)
531 * infrun.c (wait_for_inferior): Check return value from
534 Mon Oct 21 17:47:03 1991 Stu Grossman (grossman at cygnus.com)
536 * infrun.c (wait_for_inferior): fix stepi/nexti that was broken
537 by my last edit to this routine.
539 Mon Oct 21 14:27:43 1991 John Gilmore (gnu at cygnus.com)
541 * tm-sun3.h (FIX_CALL_DUMMY): problem with cross debugging.
542 FIX_CALL_DUMMY does unaligned accesses and/or forgets to byte swap
543 the values before putting them into the dummy code. (From Peter
546 Mon Oct 21 10:04:39 1991 Steve Chamberlain (steve at rtl.cygnus.com)
548 * configure.in: added ebmon target.

555 * README, TODO, WHATS.NEW: Update.
557 * core.c (core_open): Improve error message for bad file.
558 Pass .reg virtual memory address to fetch_core_registers to help
559 it find the registers in the core-file header.
560 * coredep.c (fetch_core_registers): Take new argument, use it,
561 and pass it to register_addr to locate the block of registers.
562 * xm-mips.h: Update KERNEL_U_ADDR for new scheme. Cleanup a bit.
564 * dbxread.c (read_dbx_symtab, process_one_symbol): Handle
565 Sequent N_FN_SEQ like everybody else's N_FN.
567 * main.c: Circumvent SCO cc bug with #if !!defined(USG).
568 * tm-i386v.h: #endif guck.
569 * xconfig/i386*: Remove -Dgetpagesize()=4096 kludge.
570 * xconfig/i386sco: Add HAVE_STRSTR to avoid ANSI bdeath.
571 * xconfig/tahoe: Add REGEX, which seems to be missing.
573 * coredep.c: Add <sys/types.h> for SCOnix.
574 * dbxread.c (read_dbx_symntab): Avoid coredump on malformed file.
575 * printcmd.c (print_formatted): Flush output before disassembly.
577 Tue Oct 15 20:12:32 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
579 * doc/refcard.tex (sec "Working Files"): consistent metavars and
580 other improvements, due to comments by François Pinard
581 (pinard@iro.umontreal.ca)
583 * doc/gdb.texinfo (appendix "Installing GDB"): changes in
584 configure, and improvenets related to Pinard's refcard comments
586 Tue Oct 15 08:45:12 1991 John Gilmore (gnu at cygnus.com)
588 Changes from Fred Fish:

603 * i387-tdep.c (double_to_i387): Fix typo for double_to_ieee_extended.
604 * utils.c (_initialize_utils): If !ISATTY, don't paginate.
605 * configure.in, tconfig/decstation, xconfig/decstation: Rename
606 dec3100 to decstation.
608 Mon Oct 14 13:37:50 1991 Roland H. Pesch (pesch at cygnus.com)
610 * doc/gdb.texinfo: Catch up to changes recorded here in ChangeLog
611 (nodes Continuing and Stepping; Memory; Targets) clarifications
614 Fri Oct 11 23:27:06 1991 John Gilmore (gnu at cygnus.com)
616 * tm-{irix3,mips,nindy960,pn,symmetry,vx960}.h: Move
617 REGISTER_U_ADDR to corresponding xm- file. Sugg. by Peter Schauer.
619 * symmisc.c (print_partial_symtabs): Add printpsyms debug cmd.

622 generic routines for calling inferior functions.
624 * blockframe.c (inside_main_scope, inside_entry_scope): New.

633 core-file reading code.
634 * core.c (get_core_registers): Avoid coredump if no .reg section.
636 Wed Oct 9 17:03:34 1991 John Gilmore (gnu at cygnus.com)
638 * mipsread.c, coffread.c: initialise TYPE_VPTR_FIELDNO to -1.
639 This avoids coredumps under `set print object on' in value_headof
640 (called erroneously by value_from_vtable_info) for `p &struct'
641 or `p *struct'. From Peter Schauer.
643 Mon Oct 7 00:06:52 1991 John Gilmore (gnu at cygnus.com)
645 * Makefile.in: Roll version to 4.1.2.
646 * dbxread.c: Use aout64.h, not a.out.gnu.h. Get external symbol entry
647 size from BFD (but, FIXME, we don't yet read external nlists's and
648 convert them to internal nlists's before handling them -- we still
649 assume they have the same size and alignment.) Use SET_NAMESTRING
651 * exec.c (exec_file_command): Move dead coff-encapsulation code
653 * m88k-tdep.c, m88k-xdep.c: Remove encap test and #inc <a.out.h>.
655 Fri Oct 4 22:30:06 1991 John Gilmore (gnu at cygnus.com)
657 * configure.in, tm-i386v.h, xm-i386v.h: Intel 386 Mach host port.
658 * xm-i386mach.h, mach386-xdep.c, xconfig/i386mach: New files.
660 Fri Oct 4 17:04:31 1991 Per Bothner (bothner at cygnus.com)
662 More patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
663 * mips-xdep.c (store_inferior_registers): Don't try to
664 write the (pseudo) FP.
665 * mipsread.c (parse_partial_symbols): Improved algorithm for
666 setting pst->texthigh.
668 Fri Oct 4 16:47:32 1991 Roland H. Pesch (pesch at cygnus.com)
670 * doc/Makefile: make TEXINPUTS include . everywhere
672 Fri Oct 4 00:35:56 1991 John Gilmore (gnu at cygnus.com)
674 * coffread.c, dbxread.c, symfile.c, symmisc.c, symtab.h: Remove
675 vestiges of typevectors, which were for symsegs and are no longer
676 used. (From a question by Eliot Dresselhaus
677 <dresselh@RFT30.nas.nasa.gov>).
679 Thu Oct 3 09:33:26 1991 John Gilmore (gnu at cygnus.com)
681 * dbxread.c, coffread.c: static-ize functions that were
682 gratuitiously external. (From Fred Fish.)
684 * c-exp.y: sym->class to SYMBOL_CLASS (sym).
686 * dbxread.c (dbx_lookup_type): Keep doubling size of typevector
687 until it is large enough.
689 * dbxread.c (read_type): Handle error case slightly better.
690 Make complaint message not C++-specific.
692 Wed Oct 2 17:21:07 1991 Stu Grossman (grossman at cygnus.com)
694 * infrun.c (wait_for_inferior): Fix step/next so that you only
695 stop at the beginning of a new line. This fixes various problems
696 with for loops, nested if-else's and switch statements.
698 Tue Oct 1 06:33:55 1991 John Gilmore (gnu at cygnus.com)
700 * symtab.c (lookup_symtab_1, lookup_symbol): "fatal" errors
701 between symtabs and psymtabs become ordinary error()s.
703 * dbxread.c (read_dbx_symtab): Relocate end_of_text_addr
704 properly, making "end pc" correct in shared lib psymtabs.
705 (From Guy Harris <guy@auspex.com>.)
707 Mon Sep 30 13:15:31 1991 John Gilmore (gnu at cygnus.com)
709 * dbxread.c: Enable, but soften, const_vol_complaint.
710 (read_dbx_symtab): N_STSYM and N_LCSYM define static vars.
711 Ditto Gould N_NBSTS and N_NBLCS. Also, all types in the psymtab
712 should be file-scope, not global.
713 (read_struct_type): Remove ancient multiple-inheritance warning.
714 (read_range_type): Check base type, complain & patch if undefined.
715 * stack.c (frame_info): Demangle the function name in `info stack'.
718 Sat Sep 28 10:02:33 1991 John Gilmore (gnu at cygnus.com)
720 * eval.c (evaluate_subexp_for_address): Don't use
721 TYPE_POINTER_TYPE directly (it might be zero if this type has
722 never had a pointer created before); use lookup_pointer_type.
723 * symtab.c (lookup_method_type): Arguments were swapped in all
724 callers, so fix it here. I'm amazed this worked at all!
726 Fri Sep 27 18:09:31 1991 John Gilmore (gnu at cygnus.com)
728 * c-exp.y, m2-exp.y: Define more yysymbols that happen to be
729 "bss" rather than "data" symbols, but which still conflict.
732 * coffread.c (coff_symfile_read): Use xmalloc, not malloc.
733 * core.c (core_files_info): Shorten output.
734 * exec.c (exec_files_info): Ditto.
735 (build_section_table): Ignore zero-length sections.
736 * language.c, printcmd.c: Lint.
737 * language.h (get_frame_language): Declare.
738 * saber.suppress: update.

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

781 and restore the language string after giving help.
782 * valprint.c (typedef_print): Print typedef in C or M2.
783 * symtab.c (list_symbols): Use it.
784 * main.c (main): Avoid any output before (gdb) prompt when -q.
785 * language.c (set_language_command): Handle errors by restoring
786 the language string to its current state (fix from A. Beers).
787 * doc/gdbint.texinfo: Roll in information from README. Rearrange
788 "how to install" and "how to print the doc" stuff so it drops
790 * configure.in: Rename rtpc CPU to romp to match config.sub.
791 * README, WHATS.NEW, TODO: Update for gdb-4.1.
793 Fri Sep 20 17:39:14 1991 Roland H. Pesch (pesch at cygnus.com)
795 * doc/gdb.texinfo: Updates from ChangeLog. set/show write,
796 autoloading shared libs, copyright etc on GDB startup, clean up $_
797 and $__ index refs, set/show listsize and related updates to list
798 cmd. New host/target configs.
800 Fri Sep 20 15:46:00 1991 Roland H. Pesch (pesch at cygnus.com)
802 * doc/Makefile: generate aux version-no file doc/gdbVN.m4
803 from main Makefile.in version definition
804 doc/gdb.texinfo: use version recorded in doc/gdbVN.m4 for current
806 Makefile.in (setup-to-dist): generate doc/gdbVN.m4
808 * doc/gdb.texinfo: merge new language-switching and lang-specific
811 Fri Sep 20 15:00:57 1991 Per Bothner (bothner at cygnus.com)
813 * mcheck.c: Add __ONEFILE kludge to allow compilation by non-ANSI
814 compilers (which may lack stddef.h).
816 Fri Sep 20 13:29:42 1991 John Gilmore (gnu at cygnus.com)
818 * dbxread.c (read_dbx_symtab, process_one_symbol): N_FN and
819 N_WARNING are the same except for the N_EXT bit, so just use their
820 values alone, rather than OR-ing them with N_EXT.
822 Fri Sep 20 12:27:55 1991 Stu Grossman (grossman at cygnus.com)
824 * mipsread.c (parse_lines): Deal with negative extended line
827 * c-exp.y, m2-exp.y: #define yyerrflag and yynerrs to avoid
828 global symbol conflicts.
830 Fri Sep 20 02:28:15 1991 John Gilmore (gnu at cygnus.com)
832 * .gdbinit: Move 'set complaints' to top, so it runs even in
833 case we aren't debugging GDB.
834 * language.c (_initialize_language): Fix type check and range
835 check documentation strings.
836 * utils.c (!HAVE_VPRINTF): Define vfprintf as a function, so
837 language.c can use it. (Though language.c should really not be
838 handling warnings/errors the way it does, FIXME.)
839 * symtab.c (lookup_primitive_type): const lint.
841 Bugfix from Peter Schauer:
842 * source.c (lines_to_list): Make signed, to avoid comparison
843 going unsigned and complaining that -3 is too high for 21 lines.
844 * stack.c (lines_to_list): Ditto.
846 Thu Sep 19 23:33:41 1991 John Gilmore (gnu at cygnus.com)
848 * Makefile.in (HFILES): Add minimon.h.
849 (VERSION): Roll version number to 4.0.95.
850 (gdb.tar.Z, make-proto-gdb.dir, setup-to-dist, gdb-XXX.tar.Z):
851 New rules for building distributions. Normal distribution
852 is built by doing `make -f Makefile.in gdb.tar.Z' in the directory
853 one level up from here; it calls make-proto-gdb.dir to build a
854 directory `proto-gdb' which is an image of the release. The old
855 `gdb.tar.Z' rule still works too.
856 * config.sub, configure: Roll in latest from ..
858 Thu Sep 19 17:41:24 1991 Roland H. Pesch (pesch at cygnus.com)
860 * doc/gdbint.texinfo: Reorder contents; reorganize new-host,
861 new-target, and new-config chapters; fix minor typos; come closer
862 to usual GNU markup conventions for @file @samp @code @var.

959 parser, both for language-independence, and so that scopes can
962 * language.h, language.c: New files for language-specific macros,
963 declarations, and definitions.
967 * main.c (main): If error() is called during early
968 initialization, print its message and then exit(1) from GDB.
970 * valprint.c (type_print_base): Avoid printing garbage for ints
972 (_initialize_valprint): Warn about host/target size assumption;
973 improve long long support slightly.
975 * convex-tdep.c (comm_registers_info): Avoid parsing decimal and
976 hex -- let parse_and_eval_address do it.
978 * doc/gdbint.texinfo (Languages): Doc how to add a language.
980 * Makefile.in: Cope with new files and removed files.
982 Tue Sep 17 08:37:41 1991 John Gilmore (gnu at cygint.cygnus.com)
984 Add Andrew Beers' changes for Modula-2 support. His ChangeLog
985 entries are enclosed herein. Not all of these changes
986 have been merged into the master GDB sources -- check the
987 ChangeLog above here for the merge log.
989 Mon Jun 3 17:05:45 EDT 1991
991 m2-exp.y Created. Tested outside of GDB for a few days. Proper
992 operators were added, C specific operators and tokens
993 removed. yylex() revamped to some extent. Still things
994 missing from the grammar, such as sets.
995 Tested for two weeks in GDB v3.5.
997 Tue Jun 11 17:23:48 EDT 1991
999 m2-exp.y Added boolean constants TRUE and FALSE to the grammar
1000 so they are built-in. Sort of a hack.
1002 Fri Jun 14 12:53:51 EDT 1991
1004 m2-exp.y Added range checking for numeric constants. Any numeric
1005 constant is assumed to be of builtin type INTEGER unless:
1006 (1) it is octal or hexadecimal, in which case it is a
1007 CARDINAL; (2) it is too big to fit into an INTEGER, in
1008 which case it is a CARDINAL.
1009 eval.c Added simple range checking for +, -, and * on integers.
1010 Doesn't work very well for *, since 6 * 1,000,000,000 =
1011 1,705,032,704, which fails the simple test of result >=
1012 first_operand, no matter in what order the operands are.
1014 Tue Jun 18 14:11:30 EDT 1991
1016 Broke the parser into parts, one containing the C grammar and the other
1017 containing code to be shared by all of the grammars.
1019 The following files no longer exist:
1024 The following files were added:
1026 c-exp.y (The C grammar)
1027 m2-exp.y (The Modula-2 grammar)
1028 parser-code.c (Code that is shared by the above grammar)
1032 Makefile.dist Changed to reflect the above dependencies. NOTE: It is
1033 now necessary to use the Bison compiler compiler, since it
1034 will generate function/variable prefixes other than yy.
1036 Tue Jun 18 16:47:49 EDT 1991
1038 symtab.[ch] Added the external variable working_lang, than holds the
1039 value of the current working language.
1040 Added the ennumerated type language_mode, with the values
1041 language_auto and language_manual, the former meaning that
1042 GDB sets working_lang as needed, and the latter meaning
1043 that the value of working_lang is totally under user
1045 symtab.[ch] Added the Modula-2 pervasive types INTEGER, CARDINAL,
1046 REAL, BOOLEAN and CHAR. Also added the type codes
1047 TYPE_CODE_BOOL and TYPE_CODE_CHAR.
1048 utils.c Added set_language_command and show_language_command to
1049 implement the GDB support commands "set language" and
1051 expression.h A number of identifiers were added to the type exp_opcode
1052 to facilitate Modula-2 builtin functions, integer
1053 division, and array indexing.
1055 Wed Jun 19 13:25:58 EDT 1991
1057 language.h Added the macro STRICT_TYPE, which evaluates to non-zero
1058 if the language specified by working_lang requires the use
1059 of strict typing of expressions. Eventually, even this
1060 will be able to be changed by the user.
1061 Added the macro RANGE_CHECK, which evaluates to non-zero
1062 if the language specified by working_lang requires the
1063 checking of a value against the domain of its type.
1064 Eventually, even this will be able to be changed by the
1066 language.[ch] Predicates involving types (simple_type, ordered_type,
1067 same_type, integral_type, numeric_type, character_type,
1068 boolean_type, float_type) are added. These predicates are
1069 based on the current value of working_lang, and are handy
1072 Wed Jun 19 15:39:34 EDT 1991
1074 eval.c Added the function type_array_rank which computes the rank
1076 valarith.c Added the funtion value_bool, which when given a integer
1077 value.h value (ie. struct value *) as an argument, it returns a
1078 boolean value (ie. struct value *) true if that integer
1079 is non-zero, and a boolean value false otherwise.
1080 valprint.c Added cases for TYPE_CODE_BOOL, so Modula-2 BOOLEAN values
1081 will print out properly.
1083 Wed Jun 19 16:36:34 EDT 1991
1085 valops.c Added the function value_capitalize, which returns it
1086 value.h argument capitalized if its argument is a lowercase
1087 letter, or the argument unchanged if its argument is not a
1089 valarith.c Added the function range_check_p, which returns non-zero
1090 value.h if its value argument is between the integral bounds upper
1092 Added the function range_check_enum_p, which makes sure
1093 that its value argument is a valid member of the domain of
1095 Added the function range_check_range_p, which makes sure
1096 its value argument lies between the upper and lower bounds
1097 of its type argument, which must be a ranged type.
1098 Added the function check_array_index, which range and type
1099 checks an index of an array.
1100 Added the function value_multi_subscript, which computes
1101 array[idx1,idx2...idxN], given a value array and an array
1102 of values representing indicies.
1103 values.c Changed value_from_long to work with TYPE_CODE_CHAR and
1104 unpack_long to work with TYPE_CODE_BOOL and
1107 Wed Jun 19 18:04:08 EDT 1991
1109 symtab.c Stored pervasive types in a structure and make
1110 lookup_pervasive_type() a lookup function that was based
1111 on working_lang. If lookup_pervasive_type() returned
1112 non-zero, then that value was returned (a fix, since
1113 before it simply wouldn't return the pervasive type.)
1114 language.h Added the macro CAST_IS_CONVERSION, which evaluates to
1115 non-zero if the language specified by working_lang means
1116 "conversion" when it says "cast".
1117 valops.c Added the function value_real_cast(), which performs a
1118 value.h *cast*, not a *conversion*, which is what value_cast()
1119 does when it can. In particular,
1120 value_cast(<float_type>,4) = 4.0, while
1121 value_real_cast(<float_type>,4) = some mess.
1122 eval.c Modula-2 builtin functions implemented: ABS, CAP, CHR,
1123 parser-code.c FLOAT, HIGH, MAX, MIN, ODD, ORD, TRUNC, and VAL.
1124 expression.h Added macros MAX_OF_TYPE and MIN_OF_TYPE to work with MAX
1125 and MIN on integral types. *NOTE*: These are currently
1126 hardcoded to work only if there are 8 bits per storage
1128 eval.c Made logical functions call value_bool to return a
1129 properly typed boolean value, based on working_lang.
1131 Thu Jun 20 11:55:27 EDT 1991
1133 valprint.c Types now print out in a Modula-2 fashion. This works for
1134 the cases when the type is printed out step-by-step, that
1135 is, it doesn't work when the name of a structured type
1136 (which includes the keyword "struct", etc.) is simply
1138 FIXME: Perhaps this is bad. Parts of it seem to kludgey,
1139 since type specifications in C and Modula-2 are very
1140 different. The C printing of a type is very recursive,
1141 whereas in Modula-2 it is generally very simple. C has
1142 type prefixes and suffixes, which have no real analogue in
1143 Modula-2. Maybe type_print() should call a language
1144 specific type printer. This is also advantageous if we
1145 compile GDB to exclude some of the languages. We'll just
1146 leave those functions out.
1148 Thu Jun 20 16:57:10 EDT 1991
1150 dbxread.c When reading the complete symbol table in (via
1151 psymtab_to_symtab()), the number and types of function
1152 arguments are added to a function type. define_symbol()
1153 calls add_param_to_type() to accomplish this.
1154 Assumption: when we come across a function definition
1155 (N_FUN symbol with an 'f' or 'F' in the name), its
1156 arguments will appear before another function definition.
1157 When a function is found, a pointer to its type is placed
1158 in the global in_function_type. Changes that
1159 add_param_to_type() makes are to this global.
1160 valprint.c The type of a function now includes (for Modula-2) the
1161 types of its parameters.
1162 eval.c Type checking and a check for the proper number of
1163 arguments is now done for function calls. Not sure of the
1164 impact this has on C++ member function yet.
1166 Thu Jun 20 19:58:48 EDT 1991
1168 valprint.c Rewrote the type printer. Broke it into two language
1169 specific parts, adding the functions type_print_m2() and
1171 An unfortunate consequence is this: if you debugging a C
1172 program in Modula-2 mode (why?), info types does not work
1173 well with regular expressions, since the types are printed
1174 out in Modula-2 terminology, but stored in C terminology.
1175 language.[ch] Added the functions new_type_last(), type_keyword(), and
1176 type_sep() to aid in the printing of typedefs.
1177 symtab.c Made the printing of typedefs as language independent as
1178 possible through calls to new_type_last(), type_keyword(),
1181 Fri Jun 21 11:50:26 EDT 1991
1183 dbxread.c Check all incoming ennumerated types. If it looks like
1184 Modula-2's BOOLEAN type, then change the type_code of the
1185 type to TYPE_CODE_BOOL so we can process it as a boolean
1187 valprint.c Replaced some of the 0x%x with calls to sprintf and
1188 hexformat() in val_print().
1189 language.[ch] Added the function hex_to_string(), which converts its
1190 integral argument to a hexadecimal number (format is
1191 language based) and returns the result as a string.
1193 Mon Jun 24 12:25:07 EDT 1991
1195 valprint.c Some functions call type_print_1() directly, instead of
1196 value.h using type_print(), so they can specify where (column) to
1197 print things. Since type_print() takes care of language
1198 dependence, that needs to be called first. Added a
1199 parameter depth to type_print() (so it is now like
1200 type_print_1). Changed type_print to type_print_at, and
1201 made type_print a macro that passes a depth argument of
1203 symmisc.c Changed all calls to type_print_1 to calls to
1205 Makefile.dist Made it possible to build GDB for a specific set of
1206 depend languages. Do this by passing a definition for the macro
1207 LANGS to make. LANGS should be a string containing a
1208 space-separated list of language names (ie. LANGS="c m2").
1209 The default is to build all languages. Note that grammar
1210 files must follow the naming convention of <lang>-exp.y.
1211 gdb.lang This holds the current value of the LANGS macro. It is
1212 examined every time make is called, and is updated if
1214 eval.c Added #ifdef _LANG_<lang> to these files.
1215 expread.c Still need to add them to dbxread.c and coffread.c.
1223 Mon Jun 24 16:33:11 EDT 1991
1225 language.[ch] Added the functions hexformat_pre() and
1226 hex_to_string_pre(), which take a prefix argument to
1227 include in the format string. Thus, hexformat_pre("08") will
1228 return "0x08x" (if the working language is language_c).
1229 Made hexformat() and hex_to_string() calls to the above
1230 with "" as the prefix argument.
1232 am29k-pinsn.c, arm-pinsn.c, breakpoint.c, convex-tdep.c, exec.c, core.c,
1233 dbxread.c, i386-pinsn.c, i386-stub.c, i386-xdep.c, i960-pinsn.c,
1234 infcmd.c, inflow.c, m68k-pinsn.c, m68k-stub.c, m88k-pinsn.c,
1235 mips-pinsn.c, mips-tdep.c, ns32k-pinsn.c, printcmd.c, pyr-pinsn.c,
1236 pyr-tdep.c, pyr-xdep.c, remote-vx.c, remote.c, solib.c, source.c,
1237 stack.c, sun386-xdep.c, symfile.c, symm-xdep.c, symmisc.c, tahoe-pinsn.c,
1238 valprint.c, vax-pinsn.c
1240 Changed all occurences of 0x%[0-9]*l*x in printf format strings to
1241 calls to hexformat() and hex_to_string(). Format strings without
1242 the leading "0x" were ignored.
1244 depend Updated to take the above into account.
1247 Tue Jun 25 15:27:18 EDT 1991
1249 symtab.h Added the types range_mode_t, range_check_t, type_mode_t,
1250 and type_check_t to keep track of the current state of
1251 range and type checking.
1252 main.c Added the variables range_mode, range_check, type_mode,
1253 and type_check to record the current state of range and
1254 type checking. Added initialization code to main().
1255 language.h Changed the macros STRICT_TYPE and RANGE_CHECK to examine
1256 the above variables.
1259 Tue Jun 25 17:57:08 EDT 1991
1261 dbxread.c process_one_symbol() updates the variable (enum language)
1262 source_lang based on the extension of the filename
1263 contained in the N_SO sybmol that started this symtab.
1264 When end_symtab() is called, the value of source_lang is
1265 put into the language field.
1266 stack.c select_frame() sets working_lang (and possibly type_check
1267 and range_check) to the language field of the symtab
1268 associated with the frame that is selected if working_mode
1269 is language_auto. If working_mode is language_manual, a
1270 warning is printed and working_lang is not set.
1271 language.c Added the function set_type_range(), which sets the value of
1272 type_check and range_check (if their modes call for
1273 automatic setting) based on the current value of
1274 working_lang. A non-zero argument will cause the current
1275 settings to be output.
1278 Wed Jun 26 14:51:40 EDT 1991
1280 eval.c Added range checks on assignment.
1281 m2-exp.y Added the grammar for sets to the language. Currently,
1282 these do not do anything except print an error message.
1284 Wed Jun 26 17:01:04 EDT 1991
1286 m2-exp.y Added the ability for parse_number() to parse negative
1287 numbers. A global flag is set upon encountering a unary
1288 minus. This was done to make, for example, 1 parse as a
1289 CARDINAL, and not as an integer, per Wirth's examples in
1290 Programming in Modula-2 ed.4.
1291 valprint.c Added support for "set radix 2" by then setting
1292 output_format to 't'.
1293 eval.c Implemented range checking on subrange types. Added calls
1294 to range_check_range_p for BINOP_ASSIGN and BINOP_VAL.
1295 Implemented MIN and MAX for ennumerated types. The
1296 minimum value of an ennumerated type is defined by Wirth
1297 as the first identifier, and the maximum as the last.
1298 m2-exp.y Made octal numbers ending with "B" be characters and those
1299 ending with "C" be numbers, per Wirth's book. (p. 34)
1301 Thu Jun 27 14:11:52 EDT 1991
1303 stack.c select_frame() now only sets working_lang, it does not
1304 notify the user. If working_mode is language_manual, then
1305 a warning is issued once.
1306 main.c At the end of each call to execute_command(), working_lang
1307 is checked against the local static (enum language)
1308 current. If they differ and working_mode is
1309 language_auto, the new settings of language, type and
1310 range checking are printed out.
1311 stack.c Modified frame_info() to include the language of the
1312 current frame in the output of "info frame".
1313 language.[ch] Added the function language_str() which returns the name
1314 of the current language.
1316 Fri Jun 28 15:33:14 EDT 1991
1318 m2-exp.y Added the built-in procedures INC, INCL, DEC, and DECL to
1319 the language. INCL and DECL currently cause an error,
1320 since sets are not implemented yet. INC and DEC are
1321 implemented as PREINCREMENT/PREDECREMENT with one
1322 argument, and as ASSIGN_MODIFY with two arguments.
1323 eval.c Added type checking to the above cases.
1324 value.h Added not_lval_constant to the lval_type ennumerated type.
1325 not_lval_constant means that the value is a constant
1326 value; that is 3 or 'a' or TRUE, not as in a constant
1327 identifier. This is used to help coerce numbers such as 3
1328 to either signed or unsigned numbers.
1329 valops.c Added the function value_coerce_constants() which coerces
1330 constant integers as following: if one is a constant and
1331 the other is not, the constant's type is set to the type
1332 of the other argument. If both are constants and one is
1333 signed, the other is converted to a signed constant.
1335 Sat Jun 29 17:26:29 EDT 1991
1337 valarith.c Added a better range checker. It now checks range
1338 (successfully) on integral operations [+-] (signed and
1339 unsigned) for any C sized type. Still does not work well
1340 for multiplication.)
1341 int_in_size() returns an integer that is coerced to fit into
1342 specified number of bytes.
1344 Mon Jul 1 13:04:14 EDT 1991
1346 language.[ch] Added the function binop_result_type(), which returns the
1347 builtin (struct type *) type that would be the result of a
1348 binop on the two values V1 and V2.
1350 Wed Jul 3 19:22:53 EDT 1991
1352 source.c Extended source_info() to include the source language in
1353 the output from "info source".
1355 Fri Jul 5 13:48:52 EDT 1991
1357 utils.c Moved the support functions for the GDB set/show commands
1358 dealing with language into language.c.
1359 language.c Added the function language_info(), which displays info
1360 about the current working language, type and range check
1361 settings. Called via the GDB command "info language".
1362 Added an initialization routine _initialize_language(),
1363 that sets defaults for the language, type and range
1364 variables and sets up the new GDB commands.
1365 main.c Language setup moved to language.c.
1368 Mon Jul 8 10:10:22 EDT 1991
1370 valarith.c Debugged the range checker for arithmetic. Still does not
1371 work for multiplication very well.
1373 Mon Jul 8 12:40:37 EDT 1991
1375 language.[ch] Added the function value_true() which returns non-zero if
1376 its argument represents a boolean true value.
1377 breakpoint.c Changed breakpoint_cond_eval() to call value_true() to
1378 check the truth of an expression.
1380 Thu Jul 11 12:51:34 EDT 1991
1382 language.[ch] Added the predicate structured_type(), which returns
1383 non-zero if the argument is a structured type.
1384 Added the predicate pointer_type(), which returns non-zero
1385 if the argument is a pointer type.
1386 eval.c Added the ability to do addition and substraction on
1387 pointers and integers. This case simply bypasses the
1390 Thu Jul 11 14:41:42 EDT 1991
1393 Added the symbol N_DEFD (0x4a) which is a definition
1394 module dependency that is used by the GNU Modula-2
1395 compiler and the linker. It is not important to GDB,
1396 except that [dbx|coff|mips]read.c should ignore these
1399 Fri Jul 12 16:07:00 EDT 1991
1401 valprint.c Changed the TYPE_LENGTH(type) >= 0 to TYPE_LENGTH(type) >
1402 0 in val_print(). Also added statements to the else part
1403 to coerce type (argument to val_print) to a pointer type
1404 if it is an "array of unspecified length".
1405 valops.c Added the function value_m2_string(), which returns a
1406 (value) value which is a constant string, whose type is
1407 (ARRAY [0..n] OF CHAR). The length field of the type
1408 structure is set to zero, so it will be interpreted as an
1409 "array of unspecified length".
1410 stack.c Moved the language/frame mismatch check to
1411 main.c:execute_command().
1412 main.c The working language is recorded each time
1413 execute_command() is executed. If working lang has
1414 changed during its execution, then the new
1415 language/type/range info is printed out for the user. If
1416 the working language does not match the language of the
1417 frame, a warning is issued.
1419 Sat Jul 13 16:16:39 EDT 1991
1421 eval.c Moved all the type-checking stuff for operators to
1422 language.[ch] language.c. This is so we can keep language-specific
1423 stuff (like for what type operators are defined) in
1425 language.[ch] Added the function binop_type_check(), which checks to see
1426 if its two (value) arguments are type-compatible with its
1427 opcode argument. The opcode should represent an operation
1428 involving an operator. Also added the macro function
1429 unop_type_check, which calls binop_type_check with a
1430 NULL second argument.
1431 expprint.c Added Modula-2 operators to the op_print_tab, so info
1432 expression.h break works correctly. Also added "op_string", which
1433 returns the string corresponding to the (enum exp_opcode)
1434 opcode that is its argument.
1437 Sat Jul 13 18:26:18 EDT 1991
1439 coffread.c Added code to record the type of function arguments with
1440 each paricular function. Code is very similar to that
1442 dbxread.c Moved add_param_to_type() to symtab.c
1443 symtab.[ch] Added function add_param_to_type() from dbxread.c
1445 *** NOTE: The above additions have not been tested.
1447 Mon Jul 15 12:50:47 EDT 1991
1449 langauge.[ch] Added the functions type_error and range_error, which work
1450 like error() except if the type/range mode is set to
1451 *_mode_warn, then they do not do a return_to_top_level(),
1452 but merely print a warning.
1453 Also changed [set|show]_[type|range]_command() to support
1454 the new "warn" feature.
1456 Thu Jul 18 17:50:54 EDT 1991
1458 mipsread.c Added code to record the type of function arguments with
1459 each particular function. Code is very similar to that
1462 *** NOTE: The above additions have not been tested.
1464 Fri Jul 19 11:19:10 EDT 1991
1466 defs.h Added macros MAX_OF_SIZE, MIN_OF_SIZE, UMAX_OF_SIZE, and
1467 UMIN_OF_SIZE, which when given a size of a numeric type,
1468 return the maximum and minimum value it can hold. UMAX...
1469 and UMIN... return the result for unsigned types.
1470 symtab.h Added the macros MAX_OF_TYPE and MIN_OF_TYPE to operate on
1471 struct types. They call above macros.
1472 dbxread.c Renamed the MAX and MIN_OF_TYPE macros to ..._OF_CTYPE to
1473 avoid a name conlict with the above.
1474 c-exp.y Added range checking on numeric constants in
1475 parse_number() for completeness.
1476 valarith.c Made binop_user_defined_p() and unop_user_defined_p()
1477 return 0 if working_lang is not language_c.
1479 Thu Aug 8 14:17:22 EDT 1991
1483 breakpoint.c Documentation strings of some commands changed to
1484 eliminate the references to the C language where
1487 Tue Aug 13 15:48:03 EDT 1991
1489 m2-exp.y Added qualified identifiers to the grammar. The semantics
1490 are slightly different from those of the GDB operator ::
1492 m2-exp.y Added a rule to each grammar of the form: start ::= exp |
1493 type_exp, where type_exp is any valid type expression.
1495 eval.c Added the opcode OP_TYPE, and an error case in eval.c.
1496 printcmd.c Modified ptype_command() so it actually parses the input
1497 (necessary for type expressions with scope qualifiers).
1498 Added the function ptype_eval() which expects an
1499 expression composed of one OP_TYPE element.
1500 *.[ch] Replaced all occurences of parse_c_expression with
1502 *.[ch] Replaced all occurences of parse_c_1 with parse_exp_1
1504 [End of ChangeLog entries from Andrew Beers for Modula-2 support.]
1506 Mon Sep 16 17:19:46 1991 John Gilmore (gnu at cygnus.com)
1508 Small fixes from Peter Schauer:
1510 * infrun.c (child_attach): Lint.
1511 * solib.c (find_solib): Handle shared libs version 2.
1513 Small fixes from David Wood:
1515 * xm-ultra3.h (SYS_SIGLIST_MISSING): Typo.
1519 * remote-vx.c: Move <stdio.h> to top, for FILE. Fix from
1520 John S <basrai%kanga.dnet@c3po.sm-alc.af.mil>.
1522 * utils.c (wrap_here): Avoid wrap action of fputs_filtered if
1523 chars_per_line is at maximum (user typed `set width 0'). Fix
1524 from Andreas Schwab <schwab@ls5.informatik.uni-dortmund.de>.
1526 Tue Sep 17 17:31:04 1991 Stu Grossman (grossman at cygnus.com)
1528 * coredep.c: include ptrace.h where necessary.
1529 * mipsread.c(parse_lines): fix unsigned char problem that was
1530 messing up line numbers on SGI's and possibly other MIPS based
1532 * infrun.c (child_create_inferior): use better test to check
1533 return val from setpgrp().
1534 * tm-irix3.h, xm-irix3.h, tconfig/irix3, xconfig/irix3: add these
1535 for sgi/irix support.
1537 Wed Sep 18 04:33:31 1991 Per Bothner (bothner at cygnus.com)
1539 * mipsread.c (parse_symbol): Put non-static procedures
1540 in the global block.
1542 Fri Sep 13 00:14:52 1991 John Gilmore (gnu at cygnus.com)
1544 Patch together `text_start' and `text_end' for 29K port.
1546 * exec.c (exec_command): If NEED_TEXT_START_END, define the
1547 variables and set them based on the exec file.
1548 * am29k-tdep.c: declare text_start.
1549 * valops.c (call_function_by_hand): declare text_end.
1551 * inferior.h: Eliminate CANNOT_EXECUTE_STACK in favor of
1552 defining CALL_DUMMY_LOCATION as BEFORE_TEXT_END. This is
1553 because machines that do this will also have to know to
1554 set NEED_TEXT_START_END. Besides, it was a redundant way to
1556 * tm-29k.h, tm-convex.h, tm-np1.h: Eliminate
1557 CANNOT_EXECUTE_STACK, define CALL_DUMMY_LOCATION and
1558 NEED_TEXT_START_END.
1560 Thu Sep 12 00:22:24 1991 John Gilmore (gnu at cygint.cygnus.com)
1562 AMD 29000 changes from David Wood <wood@david.ultra.nyu.edu>:
1564 * Makefile.in (CLIBS): Put XM_CLIBS and TM_CLIBS at end.
1565 Pass MUNCH_DEFINE to munch whenever we run it.
1566 * am29k-pinsn.c (print_insn): Handle NOP specially. Avoid %#x
1567 format string; use 0x%x instead.
1568 * am29k-tdep.c: Use DUMMY_SAVE_GREGS and RETURN_REGNUM.
1569 * ultra-xdep.c, xm-ultra.h: New files for Ultracomputer host system.
1570 * xm-rtbsd.h: New host support for RT/PC running BSD Unix.
1571 * inflow.c: Handle `short' process group IDs.
1572 * infptrace.c (fetch_register): Support CANNOT_FETCH_REGISTER,
1573 and check for ptrace errors.
1574 * coffread.c (SDB_REG_TO_REGNUM): Define if not already.
1575 (coff_symfile_init): Initialize text_bfd_scnum.
1576 (read_coff_symtab): Use it to find the text [and absolute?] sections.
1577 * ../config.sub: Add vendor nyu and os "sym[1-9]*".
1578 * configure.in: Add hosts rtpc-*-* and a29k-*-*.
1579 Merge target arm case with other "easy" cases. Add target
1580 cases a29k-*-none (rehack of am29k), a29k-*-kern (remote to
1581 Ultracomputer kernel), and a29k-*-sym1 (ultracomputer OS's user
1583 * minimon.h, remote-adapt.c, remote-mm.c: Add.
1584 * munch: Cope with RT/PC putting fns in data segment.
1585 Restore ability to override `nm' by specifying MUNCH_NM.
1586 * xconfig/rtbsd, xconfig/ultra3: New host systems.
1587 * tconfig/a29k: Rename from tconfig/am29k. Add remote-mm
1588 and remote-adapt. Remove encapsulated coff #define's (the
1589 support should go in BFD, and gdb shouldn't know or care).
1590 * tconfig/a29k-kern: Same, but for remote kernel debugging.
1591 * tconfig/ultra3: For debugging user processes on Ultra3/Sym1.
1592 * tm-29k.h: Update BADMAG (though it should go away).
1593 Allow the register definitions to be overridden in another
1594 tm-file. Fix SR_REGNUM. Add a mess of _REGNUM's. Separate
1595 RETURN_REGNUM from GR96_REGNUM and DUMMY_SAVE_GREGS from
1596 DUMMY_SAVE_GR96, for handling kernel calling conventions
1597 that use GR64+ rather than GR96+.
1598 * tm-ultra3.h: New file, for use on Ultra3 Unix as well as for
1599 remote debugging of Ultra3 kernel. Includes tm-29k.h and
1600 overrides various things.
1602 * remote-mm.c (mm_attach, mm_wait): Handle attach like
1603 child_attach does, making a clean stop in the newly attached
1605 * remote-eb.c: Lint.
1607 * coffread.c: Make coffread independent of any particular
1608 variant of COFF. Avoid #include-ing any particular one except
1609 internalcoff.h. BFD now passes key values for symbol reading
1610 as part of its coff_data structure (LINESZ, SYMESZ, AUXESZ,
1611 and the symbol masks and shifts); use them.
1612 Remove obsolete end_of_text_addr.
1614 * exec.c: Remove unused include files.
1616 Wed Sep 11 19:38:44 1991 John Gilmore (gnu at cygint.cygnus.com)
1618 * Makefile.in (documentation targets): Pass $(M4).
1619 Bugfix from eggert@twinsun.com (Paul Eggert).
1621 * stack.c (down_silently_command): Check for stack existence.
1623 Tue Sep 10 23:08:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1625 * Makefile.in (VERSION): Update to 4.0.3.
1627 Tue Sep 10 09:19:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1629 * core.c (core_file_command): Print frame at coredump with
1630 its level number, by calling print_stack_frame.
1631 * frame.h: Add selected_frame_level, print_stack_frame.
1632 * frame.h, stack.c: Remove print_sel_frame, print_selected_frame.
1633 * convex-tdep.c, convex-xdep.c, infcmd.c, inflow.c, infrun.c:
1634 Change print_sel_frame and print_selected_frame callers to
1637 * dbxread.c (read_ofile_symtab): Avoid empty else clause.
1638 * symfile.c (free_named_symtabs): Ditto.
1639 * main.c (main): wrap_here needs an arg.
1640 * solib.c (find_solib): Avoid memory access if _DYNAMIC is zero.
1641 (solib_add): Avoid noise.
1642 (solib_create_inferior_hook): Lint.
1643 (sharedlibrary_command): Move dont_repeat to here.
1644 * utils.c (error): Call wrap_here to force buffered output.
1646 Small patches from Peter Schauer:
1648 * coffread.c (start_symtab): Free any existing line_vector before
1650 (read_coff_symtab): Ditto for type_vector.
1652 * source.c (lines_to_list): New variable, replacing function.
1653 (all uses): Use as variable.
1654 (_initialize_source): Add 'set listsize' and 'show listsize'.
1655 * utils.c (lines_to_list): Remove function.
1656 * stack.c (print_frame_info): Use as variable.
1657 * defs.h (lines_to_list): Remove declaration.
1659 Mon Sep 9 13:45:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1661 * breakpoint.c (insert_breakpoints): Restore warning about
1662 the program might be running in another process, but only for
1663 systems with this brain death (#ifdef ONE_PROCESS_WRITETEXT).
1664 * xm-hp300bsd.h, xm-mips.h, xm-vax.h: Define it.
1666 * utils.c (error): if error_pre_print is set, print the string
1668 * main.c (main, print_gnu_advertisement, print_gdb_version):
1669 Reformat legalese so it always prints, but acts as an "I'm here"
1670 message while symbols are being read. If any errors occur,
1671 print a few newlines to set off the message and start it at the
1672 left margin. Remove mention of "help" command, and don't yak
1673 about symbol reading.
1674 (catch_errors): Error string is now printed first in case of
1676 * command.c (undef_cmd_error, lookup_cmd): On undefined command,
1677 suggest the "help" command.
1679 * Makefile.in (VERSION): Set to 4.0.2.
1681 Thu Sep 5 23:49:48 1991 John Gilmore (gnu at cygint.cygnus.com)
1683 * .gdbinit: Remove useless "rr" command. Set complaints
1684 to 1 for people debugging gdb.
1686 * breakpoint.c, remote-vx.c: Reword strings printed by
1687 catch_errors callers.
1689 Wed Sep 4 11:07:50 1991 John Gilmore (gnu at cygint.cygnus.com)
1691 * WHATS.NEW: "history write -> history save". Doc "write on/off".
1692 (Fix from kenc@viewlogic.com.)
1694 Fix some infrastructure to be able to cope with host and target
1695 machines with different sized basic types (ints, ptrs, etc).
1696 (Idea from pierre@la.tce.com (Pierre Willard).)
1698 * values.c (value_from_longest): Rename from value_from_long.
1699 Handle pointer types as well as integers, so that targets with
1700 different pointer sizes from the host can be accomodated.
1701 * breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
1702 valarith.c, valops.c, valprint.c, value.h, values.c: Rename
1703 uses of value_from_long to value_from_longest.
1704 * eval.c, findvar.c, printcmd.c, valarith.c, valops.c: Pass
1705 the correct pointer type to value_from_long{est}.
1707 * doc/gdb.texinfo ($_, $__): Describe types of these variables.
1709 * remote-vx.c: Remove obsolete code for calling functions via
1710 vxworks kludge interface (it referenced value_from_long).
1712 * valops.c (value_string): Find malloc with lookup_misc_func, not
1715 Tue Sep 3 18:37:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1717 Make writing to files work properly. (Fixes to BFD are also needed.)
1719 * core.c (core_open): Open file ourselves, read or r/w, depending on
1720 write_files. Use bfd_fdopenr.
1721 * gdbcore.h (write_files): New variable.
1722 * exec.c (write_files): Define variable, add set&show for it.
1723 (exec_file_command): Use write_files to open for read or r/write.
1725 Make shared library reading happen automatically. These changes
1726 are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
1728 * inferior.h (stop_soon_quietly): Add to exported variables.
1729 * infrun.c (child_create_inferior): call solib hook, if defined.
1730 (child_attach): call solib hook, if defined.
1731 * solib.c: Include inferior.h. Add from_tty to so_list as kludge.
1732 (find_solib): Use lookup_misc_func rather than hand-rolled.
1733 (symbol_add_stub): New stub for catch_errors.
1734 (solib_add): Avoid output if !from_tty. Catch errors rather
1735 than just calling symbol_file_add and bombing.
1736 (solib_create_inferior_hook): Interface with the target process
1737 to let it read and alloc shared libs, then figure out what it did.
1739 * core.c (validate_files): Fix typo, soften warning.
1740 (Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
1742 * utils.c (fputs_demangled): Avoid duplicate printing if
1743 demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
1745 * infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
1746 (Fix from pierre@la.tce.com (Pierre Willard).)
1748 * main.c (catch_errors): Change argument to a char * from an int,
1749 since a char * can point to a struct full of glop, but an int
1750 is not guaranteed to be able to hold a pointer.
1751 * breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
1752 breakpoint_re_set_one, breakpoint_re_set): Adapt.
1753 * core.c (core_open, solib_add_stub): Adapt.
1754 * remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.
1756 Wed Aug 28 18:18:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1758 * Makefile.in: Update VERSION to 4.0.1. Evade GNU Make bug
1759 by adding .NOEXPORT target.
1761 Fri Aug 23 17:14:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1765 * Makefile.in (VERSION): Roll to 4.0.
1766 (gdb.tar.Z): Make refcard.ps as well, for shipment.
1768 Fri Aug 23 14:07:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1770 * doc/gdb.texinfo: minor rewordings, crossref to ptype from print,
1773 * doc/Makefile, Makefile.in: generate "gdb-all.texi" rather than
1776 * doc/rdl-apps.texi: renamed from rdl-apps.texinfo
1778 * Makefile.in, doc/Makefile, doc/.Sanitize, doc/gdb.texinfo:
1779 reflect above name change
1781 * WHATS.NEW: correct pointer to refcard.
1783 * doc/gdb.texinfo: update New Features, Installing
1785 * doc/gdbint.texinfo: add short description of configure +template
1787 Fri Aug 23 11:46:08 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1789 * doc/gdb.texinfo: update, fix bugs in "Installing" appendix
1791 Fri Aug 23 01:02:00 1991 John Gilmore (gnu at cygint.cygnus.com)
1793 * Makefile.in: Add config.sub, make doc/rdl-apps.texinfo for
1794 tar file, add dependencies for referenced doc files.
1796 Thu Aug 22 22:17:06 1991 Stu Grossman (grossman at cygint.cygnus.com)
1798 * coffread.c, symfile.c, stack.c: saberized.
1800 Thu Aug 22 16:20:27 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1802 * doc/refcard.tex: permuted Essential Commands sec
1804 * doc/gdb.texinfo: new C++ chapter; revised installation appendix;
1806 set/show symbol-reloading
1807 default set complaints 0
1809 RET-repeat disabled after prompted long displays
1810 processID (attach) interpretation of 2nd GDB cmdline arg
1812 Thu Aug 22 14:05:47 1991 Stu Grossman (grossman at cygint.cygnus.com)
1814 * expread.y, coffread.c, dbxread.c, target.c, mem-break.c,
1815 cplus-dem.c, values.c, valprint.c, symfile.c, remote.c,
1816 breakpoint.c, main.c: lint.
1818 Thu Aug 22 02:02:26 1991 John Gilmore (gnu at cygint.cygnus.com)
1820 Install new configuration scheme for GDB and friends.
1822 * config.sub: Translate ordinary names to three-part names.
1823 * configure: Use three-part names internally.
1824 * configure.in: Translate three-part names to filenames.
1826 * README, WHATS.NEW: Update for gdb-4.0.
1827 * Makefile.in: Roll VERSION to 3.99.
1829 Wed Aug 21 18:21:09 1991 John Gilmore (gnu at cygint.cygnus.com)
1831 * infptrace.c (KERNEL_U_ADDR_BSD): Include a.out.gnu.h.
1832 * i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
1833 tm-m68k.h, remote-nindy.c: Change ext_format_XXX structs
1834 to single structures rather than arrays; when passing
1835 their address, use &. This avoids trouble with bdead compilers.
1836 * mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
1837 instead. This avoids portability headaches.
1838 * mips-tdep.c (mips_do_registers_info): Only print FP regs if
1840 * source.c (open_source_file): Avoid ANSI const bdeath by
1841 skipping declaration and then casting result value.
1842 * tm-hp300bsd.h: Clarify comment.
1843 * utils.c (strstr): Result is const char *; ANSI bdeath.
1844 * xm-hp300bsd.h: Define HOST_BYTE_ORDER. Redefine INT_MIN,
1845 since system include file defines it differently from "defs.h",
1846 though the two are equivalent for our purposes.
1847 * tconfig/hp300bsd: Add m68k-tdep.o.
1849 Tue Aug 20 16:01:11 1991 John Gilmore (gnu at cygint.cygnus.com)
1851 * tconfig/sun*4: Remove warnings about system assembler.
1853 Mon Aug 19 13:44:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1855 * mcheck.c: Avoid warning about undeclared abort fn.
1856 * tm-sparc.h (PC_ADJUST): Avoid calling error() from this;
1857 it causes recursive calls to error() when used in cleanups.
1858 To do so requires that we make it a function, so we do.
1859 * sparc-tdep.c (sparc_pc_adjust): New implem of PC_ADJUST.
1860 * utils.c (do_cleanups): Remove the current cleanup from the
1861 chain *before* calling it, in case error() is called from it.
1862 The result won't be pretty, but won't be an infinite loop either.
1864 Mon Aug 19 00:41:04 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
1866 * dbxread.c (read_struct_type): Grok anon structs for C++.
1867 (vb_name, vptr_name): Null terminate these strings.
1869 Fri Aug 16 08:31:03 1991 John Gilmore (gnu at cygint.cygnus.com)
1871 Minor bug fixes from BSD Net2 gdb:
1873 * blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
1874 returns 0, there is no previous frame.
1875 * breakpoint.c (commands_command): If !from_tty, don't call
1876 input_from_terminal_p().
1877 * dbxread.c (record_misc_function): Speed up slightly.
1878 (compare_psymbols): Ditto.
1879 * infcmd.c (do_registers_info): Take a second argument to
1880 determine whether to print float registers. "info registers"
1881 does not do so anymore. "info all-registers" does, now.
1882 * mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
1884 * tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.
1885 * inflow.c (initialize_inflow): Set tflags_ours correctly.
1889 * breakpoint.c (bpstat_do_actions): Use a cleanup to restore
1890 executing_breakpoint_commands if we are interrupted by error.
1891 * coffread.c (init_lineno): Avoid problem with zero-sized linetab
1892 versus malloc/free. From: john@labtam.labtam.oz.au (John Carey).
1893 * core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a
1894 catch_errors() so we can setup the frame regardless of whether
1895 the shared libs work.
1896 * ieee-float.c (double_to_ieee_extended): Get exponent from
1897 right place in little-endian systems. From John Carey.
1899 Thu Aug 15 18:43:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1901 * main.c: Remove unused terminating_signals and catch_termination().
1902 (long_options): Terminate with a zero element.
1903 [Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
1904 (gdb_readline): Make call-compatible with readline.
1905 (init_signals): Improve comments re vfork vs. signal.
1907 * utils.c (prompt_for_continue): Use new gdb_readline().
1908 If we prompt for continuation, we don't let CR repeat the previous
1909 command, once we get back to a prompt. It's too easy to keep
1910 hitting CR, expecting "--more--" prompts, and have some long
1911 command start repeating on you.
1913 Tue Aug 13 16:17:56 1991 John Gilmore (gnu at cygint.cygnus.com)
1915 * blockframe.c (frameless_look_for_prologue): Speed up by
1916 calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
1917 * tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
1918 Define two variants, one faster.
1919 * sparc-tdep.c (sparc_frame_chain): Use target_read_memory
1920 and return zero, rather than giving an error.
1921 (setup_arbitrary_frame): Initialize the PC in the new frame.
1922 (skip_prologue): Add a second arg saying whether we're just
1923 checking for a frameless function or not.
1925 * core.c (core_open, core_close, core_xfer_memory): Move
1926 section table pointers and bfd* into the target_ops.
1927 (core_open): Allow errors in shared lib reading, etc.
1928 (core_files_info): Describe shared library sections.
1930 * exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
1931 exec_files_info, set_section_command): Move section table
1932 pointers and bfd* into the target_ops.
1933 (add_to_section_table): Add BFD to section table.
1935 * target.c (target_xfer_memory, target_info): Pass target to
1936 xfer_memory and target_info functions.
1939 * gdbcore.h: Move struct section_table.
1940 * target.h: New home of struct section_table.
1942 * solib.c (solib_add): New argument is the target_ops whose
1943 section list is to be added to, if any. Reallocate the
1944 sections in that target to add any that come from shared libs.
1945 (throughout) so_sections renamed to sections.
1946 (solib_xfer_memory): Deleted.
1947 * tm-sunos.h (SOLIB_ADD): Add target argument.
1948 (SOLIB_XFER_MEMORY): Delete.
1950 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
1951 remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
1952 from target_ops. It's the same on all targets. Add two section
1953 pointers to target_ops.
1955 * stack.c (find_relative_frame): Dump ancient algorithm for
1956 "down", just use handy "next" pointers.
1957 (frame_command): Don't error if there is no stack; let user
1960 * inflow.c (new_tty_prefork, new_tty): New prefork routine
1961 modifies static state in the parent process; new_tty itself
1962 runs in the child and modifies the child's file descriptors
1963 to match the saved static state.
1964 * infrun.c (child_create_inferior): Call new_tty_prefork,
1967 * infptrace.c (child_xfer_memory): Add ignored target arg.
1968 * remote-eb.c (eb_xfer_inferior_memory): ''
1969 * remote-nindy.c (nindy_xfer_inferior_memory): ''
1970 * remote-vx.c (vx_xfer_memory): ''
1971 * remote.c (remote_xfer_memory): ''. Rename from
1972 remote_xfer_inferior_memory.
1974 * main.c (main): Only try to attach "corefile" argument if
1975 it starts with a digit.
1977 * symfile.c (symbol_reloading): New "set/show" variable.
1978 (symbol_file_add): Shorten message about symbol reading.
1979 (add_symbol_file_command): Merge with add_syms_addr_command,
1980 since this should work on all targets now.
1981 (stop_whining): Default to zero, to shut up complaints
1982 about bad symbol tables on many systems.
1983 (free_named_symtabs): Just exit unless symbol_reloading.
1985 * xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
1986 and add comment explaining shared library screw.
1988 * source.c: #if defined => #ifdef.
1990 Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
1992 * doc/gdbint.texinfo: Improve doc on porting to new OS's.
1994 Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1996 * doc/rdl-apps.texinfo: provide default readline-appendix finder
1997 (doc/Makefile knows how to make one for local config)
1999 * Makefile.in: use doc/Makefile for doc targets
2001 * doc/Makefile: GDB documentation now has its own Makefile
2002 doc/refcard.tex: renamed from "gdbrc.tex"
2003 doc/.Sanitize: add Makefile; recognize renamed refcard.tex
2004 doc/gdbint.texinfo: add markup in "Cleanups" chapter
2007 Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2009 * values.c (baseclass_addr): When reading target memory, use the
2010 length of the basetype, not the upper type. We've only malloc'd
2011 enough space for the basetype, leading to errors in free().
2013 * expprint.c (print_subexp): Print UNOP_MEMVAL of an OP_LONG that
2014 ends up as a function specially, since we know the actual type of
2015 the pointed-to address. This (somewhat) fixes display of
2016 expressions that include misc_function_vector names. Try `cond 1
2017 !strcmp("a","b")' then `i b'.
2019 * infrun.c: Move DO_DEFERRED_STORES from proceed() to resume().
2020 The child can be proceeded from inside wait_for_inferior in
2021 evaluating breakpoint conditions, and DO_DEFERRED_STORES was
2022 getting skipped in that case.
2024 * expprint.c (print_subexp): Use filtered output, since the
2025 subroutines we call use it, otherwise the output is horribly
2026 mangled, since output of wrappable stuff comes out late.
2028 * Makefile.in: Bump VERSION to 3.98.1
2030 * infrun.c (child_create_process): Use execlp to find the
2031 shell to exec our target program. This requires some fiddling
2032 with `environ' since there is no execlpe().
2034 Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2036 * Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
2037 Minor rearrangement of refcard permits two new make targets--
2038 gdbrc.dvi DVI output for refcard, using CM fonts
2039 gdbrc.ps PostScript refcard, using PS fonts
2041 Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
2045 * TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
2046 * Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
2048 Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2050 * doc/gdb.texinfo: last changes for release.
2051 Minor typo and formatting fixes; incorporated most fixes remaining from
2052 filed mail commenting on earlier drafts.
2054 Added warnings: pipes don't work in run command;
2055 conditions are converse of assertions;
2056 step over fn without debug info goes to next fn;
2057 vars may have "wrong" values near fn entrance, exit
2059 Added example from Kingston on printing repeated nonadjacent values
2061 Added explicit mention that in Emacs gdb mode C-c and C-z are like
2062 shell mode for signals
2064 Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
2065 doesn't sound so much like its parent "Stopping and Continuing"; also
2066 moved entries on continue to top of section, so they don't get lost.
2068 Improved installation directions in appendix, added manual formatting
2071 Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
2073 * configure.in: Remove xm.h and tm.h even if we aren't linking
2074 new ones, so "./configure sun4; ./configure none" does the right
2075 thing. Assume that alldeps.mak and depend are already built in
2076 srcdir, and avoid running "make" (particularly "make depend",
2077 which involves "gcc") from inside configure. Build Makefile
2078 directly rather than building Makefile.conf first.
2079 * configure: Regenerate with above changes.
2080 * Makefile.in: Use $(BISON) to find bison. Roll VERSION
2081 to 3.98. Revise gdb.tar.Z procedure to produce a file
2082 called gdb-$(VERSION).tar.Z but which unpacks into a
2083 directory called "gdb". Move non-source files out of
2084 $(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
2085 (depend): Don't try to do "gcc expread.y".
2086 (expread.o): Update dependencies by hand.
2088 Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2091 Fixed a variety of small typos that prevented info from formatting
2092 cleanly; altered too-long heading for GPL Appendix, as discussed
2093 w/RMS; Changed date on cover to July 91.
2095 Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2098 (1) Applied some fixes due to comments from Larry Breed (easier ones
2099 through chapsec 5.2)
2100 (2) Eliminated use of @footnote---had my doubts about it anyways, and
2101 it's broken in latest texinfo
2102 (3) Introduced *some* use of [] for optional arguments, where
2103 explanation is not simpler by listing cmd w arg and cmd w/out arg
2104 separately. Still not using @deffn.
2105 (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
2106 couple of headings are too long. Need patches to texinfo or revision
2109 * Partial update to README (which still needs work for this
2110 release!): (1) use of configure corrected for new script,
2111 (2) "make gdb.dvi" and "make gdb.info" mentioned.
2113 Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
2115 * symtab.c (lookup_symbol): Don't complain right off about
2116 no debug symbols; use the misc function vector first.
2117 (list_symbols): Use misc function vector to find symbols
2118 that don't have debug info, and print them.
2119 (find_pc_symtab): Temporarily avoid fatal() when psymtab
2120 PC range doesn't match symtab PC range, as it does on the
2121 MIPS because our symtab reading isn't perfect.
2123 * dbxread.c (dbx_symfile_read): Make warning about
2124 "no debug symbols" slightly nicer.
2126 * source.c (select_source_symtab): If "main" symbol exists,
2127 but decode_line_spec can't find line info, don't just return
2128 a zero; try other source symtabs or give an error.
2130 * mipsread.c (parse_partial_symbols): Sort the psymtabs by
2131 their low addresses first, then rip through fixing high addrs.
2133 * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
2134 <runene@ifi.uio.no>.
2135 (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
2137 Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2139 * Minor, mostly mechanical, cleanup of doc subdir for clean
2140 makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
2141 and gdb.info (post- texinfo2 makeinfo) generated for distribution.
2143 Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
2145 Mostly MIPS and general symbol-reading fixups.
2147 * doc/gdbint.texinfo: Add documentation on symbol-reading
2150 * mipsread.c: Remove kludges around #include "ecoff.h".
2151 Remove redefinitions of a_magic, etc, no longer used.
2152 (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
2153 Fix global overview comments to match symfile.c protocol.
2154 (mipscoff_new_init): Eliminate cur_hdr if we have one.
2155 (mipscoff_symfile_read): Eliminate unused code. Avoid
2156 sorting all the symtabs, when all we have read here is psymtabs.
2157 The symtabs are sorted as they are created anyway. Tell
2158 condense_misc_bunches whether we're mainline.
2159 (psymtab_to_symtab_1): Pass filename when recursing, to make
2160 stack trace more informative.
2161 (parse_partial_symbols): Assume cur_hdr as argument.
2162 (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
2163 Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
2164 the TYPE_NAME of char *, since that's done in symfile.c.
2165 (free_numargs, parse_symbol, add_symbol, add_block,
2166 shrink_linetable): Declare these fns void.
2167 (upgrade_type): Convert tree of if's to switch. Clean up
2168 bogus "off == 0" handling with a complaint. Avoid setting
2169 field bitpos and bitsize of array with lower and upper bounds.
2170 Check specified bitsize of elements against their actual type's
2171 bitsize, and complain if different. Complain about unknown
2173 (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
2174 (psymtab_to_symtab_1): Print names of subsidiary files that
2175 are being read in. FIXME, we read far too many files. This code
2176 is not the problem, the problem is in parse_fdr where the psymtabs
2178 (cross_ref): Result should indicate that we used one aux entry
2179 normally, or two if we encountered a "next" entry. This used
2180 to leave the caller pointing at the wrong aux entry.
2181 (add_symbol): If overflowed cur_block, reallocate it larger,
2182 chase all pointers to it, and complain(), rather than clobber memory.
2183 (shrink_block): Use xrealloc rather than xmalloc-and-copy.
2184 (new_field): Only allocate one field initially, not two.
2185 Pull ++ out of macro argument. Simplify.
2186 (_initialize_mipsread): Avoid initialization of importd
2187 global_psymbols and static_psymbols.
2189 * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
2190 to properly set pst->symtab; avoid searching for it.
2191 (symfile_fns): Improve comments, add a FIXME.
2192 * dbxread.c: Update comments to reflect symfile protocol.
2193 (read_ofile_symtab, end_symtab): Return the symtab.
2194 (psymtab_to_symtab_1): Set pst->symtab.
2196 * coffread.c (coff_symfile_read): tell condense_misc_bunches
2197 whether we're mainline.
2199 * symfile.h (sym_fns): Remove unused sym_discard member.
2200 * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
2202 * mtrace.c (mtrace): Take effect if mallwatch is set, even if
2203 the environment variable is not.
2204 * infcmd.c (finish_command): Use filtered printfs.
2205 * cplus-dem.c: Add struct tags to a few unnamed structs.
2206 * valops.c (value_coerce_array): Improve comments.
2207 * valprint.c (type_print_varspec_suffix): Print array size only
2208 if greater than zero.
2209 * m88k-tdep.c: Shift some lines left by one space, that had
2210 apparently been trashed at some point.
2211 * TODO: More things to do, a few got done.
2213 Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
2215 * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
2216 (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
2218 * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
2219 * expread.y, findvar.c, symmisc.c: Ditto.
2220 * printcmd.c (address_info): Update printed forms of LOC_
2221 symbols. Elim LOC_EXTERNAL.
2222 (print_frame_args): Keep track of param stack offsets before
2223 re-looking up to find the local register param is kept in.
2225 * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
2226 Further integration of mipsread into gdb. Eliminate unused
2227 routines, duplicate declarations. Handle static symbols in
2228 psymtabs as well as external symbols. When reading symtabs,
2229 insert symbols into the correct block (global, static, or a local
2231 (read_mips_symtab, parse_partial_symbols): Don't pass useless
2233 (mipscoff_symfile_read): Don't call select_source_symtab.
2234 (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
2235 rather than SYMBOL_VALUE.
2236 (parse_external): Comment clobbering of top_stack.
2237 (parse_partial_symbols): Update comments. Allocate and parse
2238 static symbols as well as external symbols. FIXME, enum values
2239 are not handled in this pass, but should be. Inline new_psymbol.
2240 Use SYMBOL_VALUE_ADDRESS.
2241 (psymtab_to_symtab_1): Read symbols into global static block
2242 by default (until enter some function's local block context).
2243 (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
2244 (destroy_all_symtabs, new_psymbol): Eliminate, unused.
2246 * source.c (select_source_symtab): Select a source symtab
2247 from either the symtabs or, failing that, the psymtabs.
2248 (list_command): Update error message.
2249 (forward_search_command, reverse_search_command): Use getc, not
2250 fgetc, for speed. FIXME, add comment about buffers that die if
2251 overrun by long line.
2253 * values.c (unpack_field_as_long, modify_field): Avoid shifting
2254 by an entire word, which is not portable, if we have a 32-bit
2255 field. (Code in dbxread.c already turns such bitfields, if
2256 aligned, into ordinary ints, but fixing this will help for other
2257 symbol formats and for future changes.)
2258 * core.c (core_open): Handle ANSI const brain death.
2259 * utils.c (vprintf): Fix varargs typo.
2261 Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
2263 * findvar.c (find_var_value): Handle &function better.
2264 * TODO: Document work needed on &fn and &array.
2265 * printcmd.c (print_address_symbolic): New arg is the prefix
2266 to print if a name is printed.
2267 (print_address_demangle): Honor "set print address" now.
2268 Use new arg above to improve spacing of output.
2269 * valprint.c (val_print): When printing function pointers,
2270 print symbolic form too.
2271 * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
2273 Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2275 * core.c (memory_error): Reword error msg to mislead less.
2277 * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
2279 * mipsread.c (read_mips_symtab, read_the_mips_symtab,
2280 parse_partial_symbols): Use newer BFD internals (external_filehdr
2281 and external_aouthdr), byte-swap the fields that we care about
2282 before using them, and make the file header data local to
2283 read_the_mips_symtab rather than global.
2285 Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
2287 * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
2288 from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
2290 * main.c (command_line_input): Flush stdout and stderr
2291 before every call to readline. This reportedly fixes a bug
2292 that comes up in Sys V running emacs-gdb and/or xxgdb,
2293 when stdin/out are pipes or sockets.
2295 Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2297 * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
2298 Avoid declaring Makefile dependencies, because GNU Make stupidly
2299 tries to update it if we do.
2301 * coffread.c: Revise for minor changes to bfd internal coff
2304 * configure: If -template= is given a relative path, make it
2305 absolute before recurring in subdirectories.
2307 * configure, configure.in, Makefile.in: Install "configure" script
2308 as replacement for config.gdb.
2309 * config.gdb, Makefile.dist, Makefile.sdir: Remove
2310 * README: Update for configure, mostly. FIXME.
2312 * Add dec3100 as equivalent to littlemips. Indicate in all host &
2313 target config files that they are for the host. When the lines
2314 get copied into the Makefile, this makes it more obvious what's
2317 Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2319 * sparc-opcode.h (trap opcodes): Avoid leading spaces or
2320 tabs, which end up in the disassembler output inadvertently.
2322 Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
2324 Make it compile cleanly in an ANSI GCC2 environment.
2326 * blockframe.c: <stdio.h>
2327 * cplus-dem.c: free takes a void *, ifdef __STDC__
2328 * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
2330 * defs.h (alloca): Avoid doing anything if alloca already def'd.
2331 * stddef.h, stdlib.h: Remove these files.
2332 * symtab.c: Avoid declaring qsort, close.
2333 * symfile.c: Avoid declaring close.
2334 * utils.c (vprintf): Declare "ap" arg as proper va_alist.
2335 * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
2337 Assorted other changes.
2338 * dbxread.c: include "libaout.h", not "liba.out.h".
2339 * printcmd.c (print_frame_args): Set recurse properly for
2340 indentation of struct and array parameters.
2341 * valops.c (value_cast): Allow cast to void.
2342 * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
2343 single_step() in a target-independent fashion.
2344 * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
2345 set up to be ready to continue. This makes us target independent.
2346 * infptrace.c (child_resume): Remove call to single_step; now
2347 can single step a SPARC target of any kind.
2349 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2351 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
2352 docn into separate sections---basically chapters, plus two loose
2353 pieces that can be configured to go in different places. This
2354 allows GNU m4 to preprocess the manual without coredumping.
2356 * Makefile.dist: tell TeX where to find texinfo.
2358 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2360 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
2361 the new target "rdl-apps.texinfo" which captures the Makefile
2362 variable that records where to find the Readline libraries.
2364 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
2366 * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".
2367 * tm-tahoe.h (FIX_CALL_DUMMY): Ignore more parameters.
2368 * defs.h (const, volatile): Only define if not already defined.
2369 * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
2371 * README: Update for release 3.95.
2372 * config.gdb: Don't create readline dir in subdir builds.
2373 * main.c: Include with "..." form for non-system include files,
2374 so "gcc -MM" for "make depend" works.
2375 Include readline files with "...h" rather than <readline/...h>.
2376 * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
2378 * coffread.c: Undo minor damage done by Rich Pixley. Use
2379 different internal and external representations of COFF
2380 data structures. Use new BFD routines for swapping them in and
2382 * symfile.c (free_named_symtabs): Avoid freeing file names that
2383 are null or empty. Old i960 tools seem to produce files that
2384 claim to have empty names, causing each successive file read
2385 to blow away the previous one.
2386 * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
2387 Move deferred_stores to top of file, but don't separate its
2388 #define's from its variable. Add commentary.
2389 * Makefile.dist: Fix Rich damage; undo "configure" changes in
2390 favor of keeping the (working) config.gdb. Move readline
2393 Fri May 17 12:49:56 1991 Per Bothner (via gnu at cygint.cygnus.com)
2395 * dbxread.c (read_struct_type): Try to handle g++ version 1 MI
2397 * infptrace.c (fetch_registers): no result, since now void.
2398 * tconfig/news: target depends on m68k-tdep too.
2400 Fri May 17 14:40:14 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2402 * Makefile.dist: added readline/inc-*.texinfo to dependencies for
2405 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
2406 applied various small fixes due to or inspired by RMS comments
2408 * doc/gdb.texinfo: finished using all RMS comments, save those for
2409 appendices on readline and cmd history (which are in other source
2412 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2414 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
2415 chapter 9; (2) documented 'break' command's menu mode for
2416 overloaded names, in response to hgs problem report C++ p-31
2418 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2420 * doc/gdb.texinfo: (1) better introductory example; (2) more
2421 consistent use of @code, @samp, @file, @kbd throughout; small
2422 cleanups to first three nodes; (3) new "Contributors" node;
2423 (4) Appendix, Renamed Commands; (5) divert specialized startup
2424 instructions to "Targets" chapter for generic manuals, while
2425 leaving them up front for manuals specific to specialized
2426 environments; (6) apply fixes from RMS comments through chapter 4.

2445 * Makefile: generated from above via
2449 * gdbint.texinfo: added instructions on generating gdb.info* files
2450 locally for release. These are ordinary info
2451 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
2452 Makefile)---but due to use of texinfo 2, can't count on makeinfo
2453 to generate these, so we distribute them already formatted.
2455 * gdb.texinfo: included full Info node and menu crud (as generated
2456 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
2458 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
2459 put in comments-for-future gdb.info target (one day makeinfo will

2467 set, info source, info terminal, info types, info user, set/show
2469 Also covered all recent GDB command renames for v4.

2473 * mipsread.c: Rather than keeping count of how many symtabs
2474 and psymtabs we have, for sorting purposes, count them when

2501 * remote.c: Remove decls of memory_insert_breakpoint
2502 and memory_remove_breakpoint, no longer used. (Suggestion of
2505 * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
2506 to make it easier to interface to "configure"'d libraries.
2508 Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
2510 * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as

2902 before returning locals or slocals.
2904 * i386-tdep.c (i386_follow_jump): Do not add data16 to pos in

2936 tm-sun3.h: Define TARGET_SUN3.
2938 * utils.c: Use CPLUS_MARKER not '$'.
2940 * cplus-dem.c: Use CPLUS_MARKER not '$'. If CPLUS_MARKER isn't
2941 defined, define it to '$'.
2943 * arm-opcode.h: New file (same contents as before; it had
2944 just been left out of the distribution for a long time).
2946 * tm-68k.h: Put declaration of ext_format_68881 outside the macros.
2948 * main.c: New HAVE_SIGSETMASK #ifdefs.

3014 * inftarg.c (child_open), remote-vx{,.68}.c (vx_proc_open):
3015 New function to give correct error message.
3017 Thu Apr 11 17:19:41 1991 Jim Kingdon (kingdon at cygint.cygnus.com)
3019 * target.h: Add to_doc and target_preopen.
3020 target.c: Add target_preopen and target_command.
3022 (add_target): Call add_cmd and mess with targetlist->doc.
3023 core.c, exec.c, remote-eb.c, remote-nindy.c, remote-vx.c,
3024 remote-vx.68.c, inftarg.c, remote.c: Add doc field to target struct.
3025 Call target_preopen from open routine.
3027 * main.c: Rename editing_info to show_commands.

3044 Thu Apr 18 18:08:30 1991 John Gilmore (gnu at cygint.cygnus.com)
3046 * symfile.h (free_named_symtabs): Rename from free_named_symtab.
3047 * symfile.c (clear_symtab_users_once, cashier_psymtab,
3048 free_named_symtabs): Move these routines from symmisc.c.
3049 * symmisc.c (same): same.
3050 (free_symtab): Make non-static.
3051 * symtab.h (free_symtab): Declare as exported void fn now.
3052 * dbxread.c (end_symtab, end_psymtab): Change comments.
3053 (initialize_dbxread): Call dbx_new_init() in case the first
3054 command is add-symbols.
3055 * target.c (dummy_target): Permit add_syms_addr_command.
3057 Sat Apr 13 14:46:07 1991 John Gilmore (gnu at cygint.cygnus.com)
3059 Permit symbols to be superseded when new symbol files have
3060 been read in, particularly for VxWorks.
3062 * dbxread.c (read_dbx_symtab): Allow N_SOL to cleanly take us back
3063 to the main file, as well as to include files. Also, put global
3064 functions into the global psymtab, to make "i fun" work.
3065 (end_psymtab): Free named symtabs and psymtabs for a file, once a
3066 new psymtab for it has been read.
3067 * coffread.c (end_psymtab): Free named symtabs and psymtabs for
3068 a file, once a new symtab has been read for it.
3069 * mipsread.c: FIXME. We need to do the same for MIPS, but it
3070 looks harder to determine the top-level block before it's been
3071 queued to the psymtab list.
3073 * symfile.c (symbol_file_add): Use filtered printing and wrap it.
3074 If we have wiped out any old symbol tables, clean up at end of
3076 (symbol_file_command): Don't reference symfile_fns if it's zero.
3078 * symtab.h (GLOBAL_BLOCK, STATIC_BLOCK, FIRST_LOCAL_BLOCK): New
3079 defines for the blocks of a blockvector that contain global and
3080 file-static symbols and the first of the smaller scope contours.
3081 * symtab.c (lookup_symbol, find_pc_symtab, find_pc_line,
3082 decode_line_1, make_symbol_completion_list): Use the above.
3083 * coffread.c (end_symtab, patch_opaque_types): Ditto.
3084 * dbxread.c (end_symtab): Ditto.
3085 * expread.y (block): Ditto.
3086 * mipsread.c (throughout): Ditto.
3087 * symmisc.c (free_named_symtabs): Ditto.
3089 * symtab.c (list_symbols): Process the first symbol of the
3090 static psymbols list.
3091 (types_info): Restore this function from its untimely #if 0.
3092 It's not perfect, but it is better than nothing.
3093 (_initialize_symtab): Restore "info types".
3095 Thu Apr 11 05:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
3097 * m68k-stub.c: Remote stub for 680x0's, created from
3098 rem-m68k.shar (which is removed).
3099 * nindy-share/{Makefile,Onindy.c,blout.h,env.h,nindy.c,ttyflush.c}:
3100 Remove RCS log stuff now that we use CVS and it blows our diffs.
3102 Wed Apr 10 14:18:06 1991 John Gilmore (gnu at cygint.cygnus.com)
3104 * symmisc.c (free_named_symtab): Make it work, in its current
3105 kludgy fashion. Change result to indicate if we blew away bkpts.
3106 * dbxread.c (end_symtab): Accumulate result from
3107 free_named_symtab and print warning if we blew user's state.
3108 * symfile.h: free_named_symtab now returns an int.
3110 Mon Apr 8 23:57:43 1991 John Gilmore (gnu at cygint.cygnus.com)
3112 * dbxread.c (dbx_symfile_read): Initialize psymbol list if this
3113 is the first symbol read, even if not mainline.
3114 (dbx_psymtab_to_symtab): symfile might be zero, cope.
3115 * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
3116 (set_section_command): New command ("section xxx yyy" -- should
3117 be renamed to "set section xxx yyy" FIXME) which sets the
3118 base address of a section of the exec file, overriding the
3119 virtual address that BFD reports.
3121 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
3123 * exec.c: Add add_syms_addr_command to exec_ops, so you can
3124 load symbols at any address while examining an exec file.
3126 Thu Apr 4 10:09:35 1991 John Gilmore (gnu at cygint.cygnus.com)
3128 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
3129 for printing the float info is host-dependent, not
3130 target-dependent. FIXME.
3131 * i386-pinsn.c: Move #includes to top, remove useless ones.
3132 * i386-tdep.c: Don't bother including <.../reg.h> since we
3133 don't use it (and it doesn't exist on host systems).
3135 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
3136 Convert negative numbers properly.
3137 (ieee_test): Make numbers really random; fix format arg.
3139 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
3140 * core.c (core_detach): Unpush core_ops, which might not be on
3141 top. We used to just pop the top, which broke things. Don't
3142 need dont_repeat() any more.
3143 (core_file_command): Psst! Don't repeat it.
3144 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
3145 * expprint.c (print_subexp): Avoid switch fallthru on
3146 BINOP_ASSIGN_MODIFY, so we can print += and such.
3147 * frame.h: Fix typo.
3148 * inflow.c (kill_command): After killing inferior, print our
3149 current frame in the core file, if we have one.
3150 (generic_mourn_inferior): When inferior dies, either select
3151 the current frame (in the new target, e.g. core file), or
3152 set both the current and selected frames to NULL.
3154 Changes from Peter Schauer.
3156 * infptrace.c: Avoid <sys/ptrace.h> on USG.
3158 * Make all file names fit in 14 characters (sigh and damn!):
3159 mv hp300hpux-xdep.c hp300ux-xdep.c
3160 mv symmetry-xdep.c symm-xdep.c
3161 mv symmetry-tdep.c symm-tdep.c
3162 mv convex-opcode.h convx-opcode.h
3163 mv tm-vxworks960.h tm-vx960.h
3164 mv tm-vxworks68.h tm-vx68.h
3165 mv Makefile.srcdir Makefile.sdir
3166 mv gdb-int.texinfo gdbint.texinfo
3167 mv remote-sa.m68k.shar rem-m68k.shar
3168 mv remote-multi.shar rem-multi.shar
3169 * Makefile.dist, README, config.gdb, convex-pinsn.c,
3170 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
3171 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
3174 * command.c (user_info_1, user_info): New command for listing
3175 the user-defined commands.
3177 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
3179 * dbxread.c (really_free_pendings): Clear file_symbols
3180 and global_symbols after freeing them; otherwise, running
3181 this function twice (if it appears twice on the cleanup
3182 chain), we try to free things twice.
3184 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
3185 based on text_addr (the address of text in core), not on addr (the
3186 offset between text in the .o file and in core). This change
3187 is from Peter Schauer.
3189 * main.c: Define ALL_CLEANUPS as a cast of zero.
3190 (return_to_top_level): Use it.
3191 (main): Do all cleanups after each command run as part
3192 of the gdb startup sequence. Also do all cleanups before
3193 entering the command loop, and every time we exit the command
3194 loop and reenter. Before, the cleanups from the startup sequence
3195 were being left undone until the first error!
3196 (command_loop): Rename do_nothing cleanup to command_loop_marker
3197 so we can see it easily when examining the cleanup chain.
3198 (init_signals): Add another do_nothing for signal handling.
3199 (quit_command): Only try to kill target if it has execution.
3200 Problems in the target stack got us into a state where
3201 inferior_pid was nonzero but none of the targets had execution.
3202 In this state you couldn't exit gdb.
3204 * dbxread.c: Two changes from Peter Schauer.
3205 (echo_command): Fflush output after an echo command.
3206 (show_history): Pass all args to cmd_show_list.
3208 * utils.c (init_malloc): Call mtrace to turn on tracing
3209 if the environment variable MALLOC_TRACE is set to a file name.
3210 * mtrace.c: Add source file which provides a log of every malloc,
3211 free, and realloc to a trace file.
3212 * mtrace.awk: Add source file which analyzes the trace file.
3213 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
3214 (VERSION): Roll to 3.94.3.
3216 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
3217 (check_duplicates): Don't bother with watchpoints.
3218 (set_raw_breakpoint): Comment about danger of this routine.
3219 (watch_command): Parse and eval all args before calling
3222 * solib.c (find_solib): Avoid error in referencing memory to
3223 see if any more shared libraries have been added. This is
3224 particularly useful if the target has terminated. Bug reported
3227 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
3228 in bringing up 3.94.2 on the Sun-3.
3230 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
3231 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
3232 expression (in scope) before reenabling watchpoint.
3233 * signame.c (init_sigs): Add missing declaration of i, fix
3234 sys_siglist declaration.
3235 * source.c (list_command): Fixed range computation to use
3237 * stack.c (backtrace_command): Do not allow command if target has
3238 no stack, print informative error message.
3239 * target.c (target_command): Do not write into command line
3240 because this fails if the target command is used in a user defined
3241 command. [This change was enhanced by gnu to support any-
3242 unique-prefix matching on target names.]
3243 * valops.c (value_struct_elt): Avoid infinite loop on an
3244 erroneous attempt to print the member of function (try p main.p).
3246 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
3248 * expread.y (name_no_typename): Avoid reduce/reduce errors
3249 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
3250 Since the GDB parser really doesn't use name_no_typename in a
3251 name-only context, the parser can't tell the diff between
3252 names and numbers here. Avoid allowing a name_no_typename
3253 to be a NAME_OR_*INT to resolve the conflict.
3255 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
3257 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
3259 * valprint.c (val_print_fields): bitfield printing didn't handle
3260 byte order. Indirect through a few more fns to cope.
3262 * values.c (modify_field): also cope with byte order.
3264 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
3266 Cleanup for release 3.94.2:
3268 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
3269 include files. Roll version to 3.94.2.
3271 * coffread.c (init_stringtab): Read length into unsigned char
3272 array before swapping; don't assume 32-bit longs.
3274 * target.c (target_info): Don't bother with get_sym_file, just use
3275 the symfile global variable.
3276 * symtab.h, symfile.c (get_sym_file): Delete it.
3278 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
3279 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
3280 (read_type): Replace one more error() with complain().
3282 * mipsread.c (parse_partial_symbols): Replace printf with complain.
3284 * i960-tdep.c: Fix copyright attribution.
3286 * config.gdb: Quote all backquotes in doublequotes. You can
3287 quote me on that. BSD 4.4 shell found this one.
3289 * infptrace.c (throughout): The third argument to ptrace is an
3292 * infrun.c (wait_for_inferior): When program has terminated, we
3293 have to call target_terminal_ours before we pop that target off
3294 the stack (e.g. before a call to target_kill or
3295 target_mourn_inferior). This fixes problem where a program
3296 terminates, then GDB stops for (tty output) and you have to type
3297 "fg" to the shell to resume it. FIXME: This code for what to
3298 do after termination really should be in normal_stop instead.
3300 * gdbcore.h (read_memory_check): Change declaration; it changed
3303 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
3304 4.4 prereleases, this avoids a bug in their sgtty compatability
3306 * remote.c: Use terminal.h rather than hand-rolling the same.
3308 * signame.c, signame.h (psignal): Arg is unsigned, not int.
3309 * utils.c (strsave, strstr): Fix arg types.
3310 * valprint.c (val_print): lint
3312 MIPS symbol table support from Per Bothner:
3314 * symfile.c (symtab_fns): Remove initializer table that needs to
3315 be hacked for each new symbol file format supported.
3316 (add_symtab_fns): New function, chains symbol table
3317 handlers into the global list.
3318 (symfile_init): Search this list.
3319 * symfile.h: Add next pointer, declare add_symtab_fns.
3320 * coffread.c (_initialize_coffread): Call add_symtab_fns.
3321 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
3323 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
3324 symbol *). Thus, we no longer need the hack to trash
3325 pst->filename. Good, since that hack confused code in symfile.c!
3327 (reorder_symtabs, destroy_all_symtabs): Removed static
3328 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
3329 Instead, the latter now uses a temporary array (stack-allocated
3330 from an obstack, and then freed).
3332 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
3333 haven't been set in the outermost stBlock of a procedure. This was
3334 a problem with f77 binaries on Ultrix 4.?.
3336 (new_symtab, new_symbol, new_type): Continue changing code to use
3337 obstacks more and otherwise conform to dbxread internal style.
3338 Made the free_code of symtabs be free_linetable (as in dbxread)
3339 instead of free_contents. This implies memory leaks when reading
3340 a new symbol table, until the conversion is finished. Did change
3341 (struct symbol) and (struct type) to be allocated on the
3342 symbol_obstack. Blocks and blockvectors are among the things
3345 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
3346 tested much, but it solved one problem (reported by Meissner), and
3347 cleans up some other things. The problem happened when an
3348 included file contains actual code (functions) and not just
3349 definitions. The mips coff is a little inconvenient there, since
3350 it may cause a procedure to be mapped to the wrong psymtab.
3352 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
3353 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
3354 this will need work for the new core paradigm.
3356 Opcode patches from the net:
3358 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
3359 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
3360 missing altogether - they are added here. From Bruce Bauman.
3361 * mips-opcode.h: The low mask for C0 instructions was too small.
3362 From Garrett Lau. I modified the fix to check the entire 32-bit
3365 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
3368 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3370 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
3372 * dbxread.c (read_type): Pointer subtraction (value_sub in
3373 valarith.c) sometimes failed because the types of the
3374 pointers being subtracted were not identical.
3375 These differed because dbxread.c was allocating pointer types
3376 using dbx_alloc_type+smash_to_pointer_type instead of
3377 lookup_pointer_type. I failed to find a justification for the
3378 former, so I changed it to use the latter. Similarly, I
3379 replaced smash_to_function_type by lookup_function_type,
3380 and smash_to_reference_type by lookup_reference_type.
3382 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
3383 _initialize_mipsread): corresponding changes.
3385 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
3387 * source.c (mod_path): Do tilde_expand on each component of the path,
3388 rather than on the (list of) paths as a whole.
3389 (print_source_lines): Set first_line_listed in addition to
3390 current_source_symtab and current_source_line. If the source was
3391 not findable, after a "dir" command to fix the problem,
3392 a "list" would get the wrong lines.
3394 While I was there... (gnu):
3396 * dbxread.c (read_type): Change error to complaint.
3398 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3400 First attempt at detailed understanding of symbol table memory alloc.
3402 * dbxread.c (dbx_symfile_read): Free our string table if we
3403 aren't the mainline. Free the "info" struct since we're done with
3405 (init_psymbol_list): Free any previously allocated psymbol lists.
3406 (): FIXME: Should realloc-down the psymbol lists when done reading
3407 the main symbol file?
3409 * symmisc.c (free_symtab): Free fullname field too.
3411 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
3412 (REGISTER_ADDR): Make result type unsigned int.
3414 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
3415 define REGEX must also define REGEX1 (its dependency).
3417 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
3419 * tconfig/i960: No longer works, points you at vxworks960 or
3422 * xgdb.c, XGDB-README: Remove file. Users can get the much
3424 * Makefile.dist: Remove all trace of xgdb.
3426 * breakpoint.c (breakpoint_1): Pass demangle arg to
3427 print_address_symbolic.
3428 (clear_breakpoints): Remove unused function.
3429 (breakpoint_re_set_one): Guts of breakpoint_re_set.
3430 (breakpoint_re_set): Use catch_errors to do them all anyway.
3432 * gdb-int.texinfo (Host versus Target): Add section on what is
3433 a "host" feature versus what is a "target" feature.
3435 * infcmd.c (path_command, path_info): Handle the PATH variable
3436 (object search path) as conveniently as the source search path.
3437 * environ.c (set_in_environ): Set some vars in GDB's environment,
3438 in addition to the child's. PATH, G960BASE, G960BIN for starters.
3439 * source.c (mod_path): New function, from guts of
3440 directory_command, modifies a path. Used by path_command.
3441 (directory_command): Call it.
3442 * defs.h (strsave): Declare.

3445 (printchar): Use it.
3446 (strsave): Provide this handy helper routine.
3447 (set_width_command): Rename set_screen_width_command.
3448 (_initialize_utils): "set screen-width" => "set width";
3449 "set screen-height" => "set height"; add sevenbit-strings.
3451 * infcmd.c (do_registers_info): Print floating point registers
3452 in raw hex as well as float format, regardless of whether it is
3453 a "virtual" convertible register.
3454 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
3455 regs as a double, just in case it's being used that way.
3456 * values.c (unpack_long): Comment on array/function coercion.
3457 (unpack_double): Argument is in target byte order now. For
3458 integer arguments, just call unpack_long and float the result.
3459 * m68k-tdep.c: include defs.h for "const" handling.
3460 * remote-nindy.c: Use ieee-float stuff.
3461 (nindy_fetch_registers): Unpack double regs to host double, then
3463 (nindy_store_registers): Pack extendeds to host double, flip
3464 around by misusing unpack_double, send as target double.
3466 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
3467 zero, as when stopped at the first instruction of a process.
3469 * blockframe.c: Fix filename in comment (param.h => tm.h).
3470 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
3471 * tm-68k.h: Fix typos.
3473 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
3475 Changes from a bringup on the DEC Vax under Ultrix 4.0.
3477 * coredep.c (fetch_core_registers): Pass end-address of register
3478 section to register_addr as expected. Don't call supply_register
3479 if we'd just pass it garbage.
3481 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
3483 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
3485 * target.c (push_target, target_info): Cast enums to int for < or

3489 even if we can't print it.
3491 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
3493 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
3495 Clean up IEEE floating point support.
3497 * ieee-float.h: New file.

3502 sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
3503 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
3504 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
3505 double_to_ieee_extended.
3506 * i960-tdep.c: Define ext_format_i960.
3507 * m68k-tdep.c: Define ext_format_68881.
3508 * sparc-tdep.c: Define ext_format_sparc, though unused.
3509 * Makefile.dist (HFILES): Add ieee-float.h.
3510 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT

3516 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
3517 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
3518 * tconfig/nindy960: Remove reference to coffstrip.o.
3520 * Makefile.dist: Roll version number to 3.94.1 (not yet final).

3525 * dbxread.c: Remove static symfile_bfd.
3526 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
3528 * inftarg.c (child_detach): Pop the child_ops vector if the
3529 detach is successful.
3530 * remote-nindy.c (nindy_create_inferior): Don't push a new
3531 nindy_ops since nindy uses the same one for execution and memory
3533 * core.c (core_ops): Use child_attach and child_create_inferior
3534 rather than default attach and create_inferior functions.
3536 Handle floating point registers in core files.
3538 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
3539 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
3540 This version untested since BFD doesn't yet support sun3 core
3542 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
3543 conventions. Fix comments and style. This version has not
3544 been compiled yet, since we have no HP inhouse.
3545 * core.c (get_core_registers): Look for two sections, ".reg"
3546 and ".reg2", and pass both to fetch_core_registers sequentially.
3548 Revise directory path yet again.
3550 * source.c (forget_cached_source_info): Not static any more.
3551 (init_source_path): New default source path is "$cdir:$cwd".
3552 (dir_command): Handle variable arguments ($cdir, $cwd).
3553 (source_info): Print "Compilation directory" rather than
3554 "Originally compiled in" to remind people of $cdir.
3555 (openp): If the path contains $cwd, use current directory.
3556 (open_source_file): If compilation directory is known, replace
3557 first $cdir in path with the compilation directory.
3558 (print_source_lines): Even if we can't print the lines, set the
3559 current symtab and line for future commands like "info source" or
3560 "breakpoint". Also, error message now contains the file name,
3561 line number, and file access error message.
3562 (_initialize_source): Fix help text to describe changes.
3563 * main.c (cd_command): Forget cached source info when we chdir.
3564 * utils.c (strstr): Add simple implementation.

3568 * coffread.c (read_one_sym, init_linetable, init_stringtab):
3569 Byte-swap COFF symbol tables if necessary when reading them in.
3570 Use complain() to replace error message in one spot. Needs
3571 corresponding change in bfd/coff-code.h to make some symbol
3572 swapping routines non-static.
3574 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)

3586 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
3588 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
3589 <rpc/rpc.h> and <rpc/types.h>.
3591 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
3593 * i960-tdep.c (examine_prologue): Add new argument limit,
3594 which stops the scan at the end of the prologue, or at the PC.
3595 This fixes a problem where it walks down into the code for the
3596 user's statements if that code looks like function prologues.
3597 Mark Fox and I have been bouncing this code back and forth, making
3598 small changes to it. Callers changed to match.
3600 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
3602 Cleanup for gdb-3.94 release final:
3604 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
3605 the .c files from vx-share and nindy-share, from the various
3606 macros, since they are not found via ALLDEPFILES.
3607 (SFILES): Add tm-i960.h.
3608 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
3609 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files

3616 * am29k-tdep.c: Add contribution line.
3617 (examine_prologue): Cache information about function prologues in
3618 the misc-function-vector to avoid lots of references over the
3619 serial line while examining instructions.
3621 * core.c (core_close): New function made from cleanup_core.
3623 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
3624 remote-vx.c, remote.c, target.c, target.h,
3625 Update target_ops vector to add attach, close, and load entries.
3626 Use add_syms_addr_command, not add_file_addr_command, for
3627 add_file. Break out close routine from existing code.
3629 * dbxread.c (really_free_pendings): Don't free pending_blocks;
3630 they are in an obstack.
3631 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
3633 (define_symbol): Add symbol type parameter; change callers;
3634 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
3635 it to influence the symbol class on the i960.
3636 (define_symbol): Swap LOC_CONST's into target byte order.
3638 * exec.c (exec_close): New function.
3639 (exec_file_command): Call it.
3641 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
3642 Fix byte order of frame pointer.
3643 (read_var_value): Result of 0 if var's value can't be found,
3644 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
3645 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
3646 (locate_var_value): Use read_var_value and use its lazy address
3647 as the location of the var's value. Lint.
3649 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
3652 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
3653 obsolete Intel versions in favor of vxgdb versions.
3654 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
3655 code dealing with byte order of values, which Intel did in host byte
3656 order rather than gdb-4's target byte order.
3657 (i960_frame_chain_valid): Move to nindy-tdep.c.
3658 (examine_prologue, skip_prologue, frame_find_saved_regs,
3659 frame_args_address, leafproc_return, saved_pc_after_call,
3660 pop_frame): Add vxgdb versions from Mark Fox.

3662 to deal with the saved value of G13 (struct return address
3664 (frame_args_address): Modify Mark's version to prefer the
3665 saved value over the current value in the topmost frame.
3666 Cache result in the frame info to avoid performance hair in
3668 (print_fault): Add gdb960 code for printing faults.
3669 (_initialize_i960): Actually call check_host.
3671 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
3672 add stub routines. FIXME, these currently just return zero!

3675 (attach_command): Call target_attach, not target_open, now.
3677 * infrun.c (normal_stop): Make global, not static, for vx_attach.
3678 (child_attach): Rename from child_open.
3679 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
3680 don't confuse it with a zero step_resume_break_address.
3682 * inftarg.c (child_detach): Eliminate inferior_pid test.
3683 (child_files_info): Clean up message a bit.
3684 (child_ops): Use child_attach, not child_open, to attach.
3686 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
3687 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
3688 findvar.c to here, since it depends on the contents of the
3689 shadow_contents of breakpoints, but keep if #if 0 since it is
3692 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
3695 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
3696 (ptype_command, display_command): Eliminate have_inferior_p and
3697 have_core_file_p in favor of target_has_stack or
3698 target_has_execution.
3699 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
3700 code for actually finding the values of arguments, though we still
3701 keep track of the maximum stack offset for use in printing unnamed
3702 arguments. Handle missing FRAME_ARGS_ADDRESS.
3704 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
3705 (struct nindy_regs): Define registers passed to/from nindy.
3706 (nindy_fetch_registers, nindy_store-registers): Translate between
3707 nindy and GDB formats for the registers.
3708 (dcache_init): Statically allocate the cache, since it was being
3709 allocated by a malloc that was never freed anyway.
3710 (nindy_create_inferior): Error, not core dump, if no exec file.
3711 (nindy_before_main_loop): Use target_load, not target_add_file.
3713 * remote-vx.c (net_load): Specify large timeout for load
3714 requests. Allow user to break out with INTERRUPT.
3715 (net_break): Remove useless code, clean up. Change callers.
3716 (parse-args, skip_white_space, find_white_space): Clean up arg
3717 parsing to cope with quoted strings.
3718 (net_wait, net_quit): Never call error, just return status.
3719 (vx_read_register, vx_write_register): Cleanup status checking.
3720 #ifdef the code based on which CPU we are using (960 or 68k),
3721 FIXME, this should be completely general but it isn't yet.
3722 (vx_xfer_memory, vx_resume): Cleanup status checking.
3723 (vx_run_files_info): Improve message.
3724 (vx_load_command): Renamed from vx_add_file_command. Allow load
3726 (net_ptrace): Remove unused routine.
3727 (vx_wait): Adopt code from vxgdb960 to cope with broken
3728 connections to target machine and prompt to disconnect. Remove
3729 debug printouts. Map some EVENT_'s to SIGnals.
3730 (add_symbol_stub, vx_open): Print names of object files we found,
3731 and "ok" if we read their symbols OK. Clarify output in general.
3732 (vx_attach, vx_detach, vx_kill): Add these commands.
3733 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
3734 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
3735 "info files" output, and create_inferior, since we already have
3738 * stack.c (frame_info): Replace Frame_unknown with 0.
3739 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
3740 (return_command): Pop until the PC matches as well as the FP,
3741 so it works even if the FP is shared with another function,
3742 as in "frameless" or "leaf" procedures.
3744 * symfile.c (load_command): renamed from add_file_target_command.
3745 (add_syms_addr_command): renamed from add_file_addr_command.
3746 (add_syms_command): Stub to call target_add_syms.
3747 (_initialize_symfile): Change command names and descriptions,
3748 add-file => add-syms, and load from alias to its own command.
3750 * target.c (kill_or_be_killed, maybe_kill_then_attach,
3751 maybe_kill_then_create_inferior): Default for attempts to start
3752 a process, if one is already running, is to ask about killing
3753 it and retry if yes.
3754 (upstack_create_inferior): #if-0 it, strata obsolete it.
3755 (push_target, unpush_target, pop_target): to_close() a target
3756 before unstacking it.
3757 (target_info): Renamed from target_files_info.
3758 (_initialize_targets): Rename "i files" as "i target", accessible
3761 * target.h: Improve comments about the target_ vectored routines.
3763 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.

3766 (SKIP_PROLOGUE): No longer a no-op.
3767 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
3768 (*_REGNUM): Sort register numbers.
3769 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
3770 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
3771 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
3772 are now 10 byte extendeds, not 8 byte doubles.
3773 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
3774 for nindy versus vxworks targets. FIXME, this should possibly go
3775 in the target vector.
3776 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
3777 frame_saved_regs and arg pointer with each frame.
3778 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
3779 (FRAME_ARGS_ADDRESS): Use cached result.
3780 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
3781 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
3782 (PRINT_RAMDON_SIGNAL): Call print_fault.
3783 (POP_FRAME): Now works.
3785 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
3786 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
3787 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
3788 (ADDITIONAL_OPTION_HANDLER): use target_load, not
3791 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
3792 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
3794 * valarith.c (value_subscripted_rvalue): Avoid handling
3795 floats and doubles specially; it gave alignment errors. Lint.
3797 * valops.c (value_of_variable, value_of_this): Error if unknown
3800 * valprint.c (print_floating): Bcopy rather than pointer-deref,
3801 to avoid alignment problems.
3802 (value_print): Handle unknown value address.
3803 (cplus_val_print): Two args are ignored; remove them. Change caller.
3804 (val_print): Use unpack_long rather than pointer-deref.
3807 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
3808 to avoid alignment problems.
3809 (value_being_returned): Error if return value unknown.
3810 (set_return_value): Add bogosity warning, FIXME. *
3812 * TODO: A woman's work is never done.
3814 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
3815 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
3816 Add ieee-float.o to OBS.
3817 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
3818 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
3819 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
3821 Changes to generalize the VxWorks RPC protocol slightly, to handle
3822 i960 as well as 68000.
3824 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
3825 * vx-share/reg.h: Produce i960 regs #ifdef I80960
3826 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
3827 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
3828 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
3829 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
3830 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
3831 so they will move in target byte order rather than network
3832 byte order (happens to be the same).
3834 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
3836 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
3838 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
3841 Add contribution lines to various files, showing where they
3844 * breakpoint.c (break_insn, check_break_insn_size,
3845 read_memory_nobpt): Remove to mem-break.c.
3847 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
3850 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
3851 entry has bad register number. This change is not
3852 tested in this release, FIXME.
3854 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
3857 * value.h: Force value's contents field to be aligned to hold
3858 at least a double or a long long (if supported). This avoids
3859 doing bcopy's in and out of the contents field.
3861 (step_1): Avoid coredump under obscure circumstances when we
3864 * symtab.h (misc_info): Add field to misc function vector for
3865 any kind of cached information the target code desires. AMD
3866 29000 uses this to avoid repeating examine_function_prologue's.
3868 * coffread.c: Lint. Remove static symfile, read_section_header.
3869 core.c (have_core_file_p): Lint: remove.
3870 expprint.c (print_subexp): Lint.
3871 infptrace.c, valops.c, valprint.c: lint.
3873 Roll in changes from vxgdb-5.0.1:
3875 * symtab.h: Comment byte order of each address class. Add
3876 LOC_LOCAL_ARG for frame-relative args (960).
3877 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
3878 symtab.c, symmisc.c: ditto.
3880 * infrun.c (init_wait_for_inferior): Clear stop_signal.
3882 * remote.c (remote_resume): Error if resume with a signal.
3884 * symfile.c (prim_record_misc_function): Clear misc_info.
3885 (fill_in_vptr_fieldno): Check stub type of arg.
3887 * valops.c (value_cast): Avoid looking up names of types whose
3888 name we don't know, to prevent coredump. Sun CC produces typedef
3889 rtx and the name of *rtx is zero...
3891 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3893 Roll in changes from final AMD 29000 port (Tiemann).
3895 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
3896 for ../include/a.out.encap.h. This might not work now that BFD
3897 is separately compiled. Instead, BFD support for encap will have
3898 to translate machine type 29k into the right COFF_MAGIC.
3900 * infcmd.c: Remove references to inferior_pid that aren't used
3901 in actual ptrace calls; use target_has_execution, etc.
3902 (have_inferior_p): Remove function.
3903 (program_info): Print target info rather than "process number";
3904 avoid gratuitous messages unless from_tty.
3905 (run_stack_dummy, finish_command): Set proceed_to_finish.
3906 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
3907 main.c: Lint. Lose have_inferior_p().
3908 inferior.h (have_inferior_p): Remove, lint.
3909 (proceed_to_finish): Add flag to ask that all regs be saved
3910 by normal_stop, for the few commands that need it, speeding up
3911 serial I/O. Add comments to stop_registers.
3913 * remote-eb.c: Remove newline from breakpoint message we grep
3914 for. Never time out when running the user program.
3918 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3920 Roll in changes from vxgdb-5.0.1:
3922 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
3923 symbol in its raw form, we are processing an unlinked ".o" file.
3924 See if the target environment has assigned it an address, using
3925 target_lookup_symbol (VxWorks does), and enter it into the symtab
3928 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
3929 68k versions for a simpler version that assumes zero FP at bottom.
3930 Fixes bug of truncated stack reports.
3932 * target.h (target_lookup_symbol): Define this routine's args
3933 and result, finally.
3935 * target.c (nosymbol): Default routine for target_lookup_symbol.
3936 (target_default): Default lookup_symbol and call_function too.
3937 (files_info): Only print has_all_memory warning if a non-dummy
3940 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
3941 vx_convert_from_virtual): If target does not have floating point,
3942 zero register "values", and avoid doing cross-net conversions.
3943 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
3944 (vx_open): Rearrange code that attaches to target and reads
3945 symbols for all loaded modules, to work if some of the modules
3946 are not accessible. Add symbol_stub() and add_symbol_stub()
3947 as callbacks from catch_errors(). Allow connect attempt to be
3948 interrupted painlessly with ^C (FIXME, there are still some bugs
3949 if the interrupt happens during symbol reading.). Print
3950 final message with puts_filtered, since symbol messages are
3955 * main.c (catch_errors): Only print errstring if non-null.
3956 (command_loop): Avoid an ioctl per command to test ISATTY.
3958 * remote-vx.c (net_load): make static; avoid sophomoric msg.
3959 (vx_xfer_memory): Return correct result!
3960 (vx_files_info): Indicate whether target has float or not.
3961 (vx_lookup_symbol): Complain, not error, if target gone.
3962 (vx_open): Print "Connected" msg before disabling immediate-quit.
3963 [FIXME: lookup_symbol and vx_open changes need testing.]
3965 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
3966 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
3967 contributor lines and update copyrights to 1991.
3969 Changes from an attempted H-PUX host port:
3971 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
3972 defines PT_ATTACH and PT_DETACH but not PT_KILL.
3973 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
3974 * remote-vx.c: include <sys/time.h> for HPUX.
3975 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
3976 "core_file_command" routine to BFD regime. May not work yet.
3978 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
3980 * xgdb.c: Replace X10 version with some VJ version.
3981 (FIXME: Its copyright assignment is not on record.)
3982 * xgdb.c: Update include files to X11R4 (Xaw crud).
3983 (xgdb_display_source, create_text_widget): fix call to
3984 get_filename_and_charpos. Rewack source window stuff for X11R4
3985 (gleaned from include files, and "nm's" of binary libraries, since
3986 I had no doc available).
3987 (append_selection, append_selection_word): Disable with FIXME
3988 since R4 changed interface here.
3989 (create_buttons): Add back the old set of buttons.
3990 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
3992 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
3993 Roll VERSION to 3.94 (not yet final though).
3995 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3997 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
3998 obstack_int_grow, obstack_int_grow_fast): Eliminate
3999 cast on left of assignment, which gives MIPS cc fits and is
4002 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
4003 F_ALIAS. Use printf, not fprintf, when not passing a file
4005 (compare_opcodes): Check that identical instructions have
4006 identical opcodes, complain otherwise.
4008 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
4009 was reported by Roland McGrath.
4010 (unimp): Only match if exactly zero instruction. (Roland)
4011 (branches and traps): Generate all variations of these
4012 instructions with macros, based on a single call that defines
4013 each condition name and its binary representation.
4014 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
4016 * valprint.c (val_print_fields): Take, and use, format parameter.
4017 This means that "p/x struct" again prints the elements in the
4018 desired format. Changed callers.
4020 * stack.c (frame_info): Use filtered output, and indicate wrap
4021 points. Remove kludgy formatting designed to avoid line wrap.
4023 * utils.c (wrap_here): If the line is already full (because
4024 we had printed a long indent or long wrapped string), do an
4025 immediate newline-and-indent.
4027 * m68k-pinsn.c (print_insn_arg): Bugfix from
4028 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
4029 instruction is incorrectly disassembled as bkpt #8.
4031 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
4032 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
4033 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
4034 and then will dump core (sometimes). I traced it back to an
4035 uninitialized symfile_name in psymtab_to_symtab.
4036 (const_vol_complaint): Add quotes to message.
4037 (define_symbol): Only believe line number if gcc_compiled.
4038 Avoid allocating symbol if we will not return it.
4040 Add target strata support so that newly established targets go
4041 into their right place in the target stack (e.g. a new exec file
4042 doesn't wipe out the ability to access the running process).
4044 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
4045 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
4046 and initialize it properly in all the targets.
4048 * target.h: Document strata. Change return type of push_target.
4050 * target.c (nomemory): new function for dummy memory access.
4051 (tcomplain): Rename complain, now also used in symfile.c.
4052 (push_target): Push targets within strata. New return value shows
4053 whether new target is on top of stack or not. Always keep dummy
4055 (target_files_info): Ignore dummy target.
4057 * core.c (core_open): Warn user, and skip accessing file, if the
4058 core target is not the topmost target in the stack.
4059 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
4062 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
4063 target_ops, it doesn't belong there since we have no regs there.
4064 Change name of target from machine => memory to clarify.
4066 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
4068 * Freeze version 3.93 for release.
4070 * Makefile.dist: Handle vx-share and nindy-share subdirs
4071 properly when building gdb.tar.Z.
4073 * symtab.c: lint; add no_symtab_msg to consolidate the messages
4074 printed in various places, so I could change just one copy.
4076 * dbxread.c, coffread.c: Change references to bfd->iostream
4077 to cast to FILE *, now that BFD avoids needing types defined
4078 in other header files.
4080 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
4082 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
4083 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
4084 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
4085 (actually gcc -Wall).
4087 * dbxread.c: Remove first_global_sym, last_global_sym, since
4088 they are never referenced.
4090 * defs.h (baud_rate): Declare.
4091 main.c: Define it, and add the -b option to set it.
4093 * gdb-int.texinfo: Add text on how to define a new host or target
4094 architecture, prompted by Per Bothner's questions about MIPS
4097 * gdb.texinfo: Document "complaints". Change doc of -q since
4098 gdb no longer prints the copyright and blurb if you specify a file
4099 name to be debugged (just like Emacs). Add doc for Nindy-specific
4100 command line flags for specifying target serial port and such.
4101 Update copyright to 1991.
4103 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
4104 has taken over for us the job of ripping up executable files. The
4105 crud caused Per Bothner's port to not compile.
4107 * infrun.c (normal_stop): Avoid printing "Program exited
4108 normally" if we are in batch mode. This allows a GDB which
4109 executes a program on a target system, to behave like a Unix
4110 command (input from stdin, output to stdout, no extraneous
4113 * main.c (main): Allow additional machine-dependent command line
4114 options to be specified with the ADDITIONAL_OPTIONS,
4115 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
4116 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
4117 processing to occur just before the main loop with
4118 BEFORE_MAIN_LOOP_HOOK.
4119 (main): If a "core file" argument is specified, and it is not a
4120 core file, try it as a process ID to attach.
4121 (symbol_completion_function): Attempt to cope with
4122 "show screen-" TAB, not very successfully. This needs more work,
4124 (batch_file): New function, returns whether we are reading
4125 commands from an interactive tty on stdin, or from somewhere else.
4126 Called by normal_stop since it doesn't get from_tty passed down
4127 to it like many commands do.
4129 * remote-nindy.c: Handle command line options for nindy
4131 (nindy_before_main_loop): Prompt user for tty name if they
4132 don't specify it before getting to the interactive command loop.
4134 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
4135 and -r command line options. Also add hook before main loop
4136 to make it easy to specify a tty.
4138 * TODO: More things to do, one done.
4140 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
4142 * dbxread.c: Make complaint() calls pass pointer, not struct.
4143 Add complaints about badly formatted C++ type information
4144 (const/volatile indicator, and parse errors resulting in
4145 error_type). Fix C++ virtual member fn comment.
4146 (read_struct_type): Avoid bumping pointer if we got a parse
4147 error; this prevents our walking beyond the end of a string.
4148 Terminate loop on null char as well as semicolon.
4149 (process_one_symbol): Fix the LBRAC fix so that it uses the
4150 last previous SLINE, FUN, or SO record's PC address. C++ debug
4151 symbols did not have SLINE records in a useful order compared
4152 to the LBRAC records.
4153 (define_symbol): Handle "catch" records.
4155 * symtab.c (check_stub_type): Added new complain
4156 `stub_noname_complain' and added a consistency check to
4157 keep the debugger from crashing when finishing from an
4158 exception frame. A real fix will be needed later.
4160 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
4162 * infcmd.c (attach_command): Make global.
4164 * Makefile.dist (REMOTE_OBS): Make these compile by default,
4165 but make them easy to comment out. Perhaps later they should
4166 be enabled by what CPU you configure for? FIXME.
4167 (VERSION): Roll to 3.93.
4168 (pinsn.o): Remove rule for obsolete file.
4169 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
4171 Run down a problem that manifested by printing the wrong function
4172 name in stack traces of read_ofile_symtab. Turned out that the
4173 problem was the SunOS 4.1.1 (and previous) C compiler outputs
4174 the LBRAC symbol with an address in the *data* segment, which
4175 blew our binary search through the blocks.
4177 * dbxread.c: Use the complain() facility consistently to bitch
4178 about problems in the symbol file we are reading.
4179 (finish_block): Add code to check the nesting of the blocks;
4180 complain and Procrust them to fit if wrong.
4181 (make_blockvector): Check the order of the blocks, complain
4182 [but don't cope] if wrong.
4183 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
4184 symbols to be sure their PC value is greater than the last SLINE
4185 (line number) symbol we've seen, complaining and adopting the
4186 SLINE PC value if wrong.
4188 * symfile.h (struct complaint, complaint_root, complain,
4189 clear_complaints): Add.
4190 * symfile.c (complain, complaint_root, clear_complaints): Add
4191 facility to deal with non-fatal complaints and to regularize their
4193 (symbol_file_add): Clear complaint counters to allow new complaints.
4194 (initialize_symfile): Add 'set complaints' and 'show complaints'.
4196 * dbxread.c (dbx_symfile_read): Remember the address and size
4197 of the string table for the main symbol file, so we won't read it
4199 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
4200 to avoid reading the string table yet again. Lint.
4201 (throughout): Improve filtered output, including word wrap.
4202 (read_range_type): Improve Bothner's fix to handle other types too.
4204 * utils.c: Improve line wrap implementation. Handle unlimited
4205 width by making chars_per_line unsigned.
4206 (puts_filtered): New, easy, function.
4208 * defs.h (puts_filtered): add.
4210 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
4211 call the identical sort_symtab_syms() in symfile.c instead.
4213 * expread.y: Suggest the `file' command rather than `symbol-file'.
4215 * command.h (enum var_types): Add zinteger for seroable
4217 * command.c (do_setshow_command): Handle var_zinteger. Restructure
4218 nested if's into a switch.
4220 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
4221 we did not stop because of a breakpoint (it must have been for
4222 some other reason, like a "stepi"), so don't print anything.
4224 * symtab.c: Include <sys/types.h> all the time. Now that BFD
4225 doesn't include <sys/types.h>, old SunOS's require it for
4228 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
4230 A test port of gdb-3.92.6 to the Sony NEWS.
4233 Don't normally link in remote- or vx stuff.
4234 Some of it doesn't compile, and it wastes space for 99% of the users.
4235 Remove reference to no-longer-used HAVE_VPRINTF.
4236 Fixed BFD_DEP typo to BFD_DIR.
4238 Fix cast in arg to bfd_h_getlong.
4239 Make char *prefix be const.
4240 Fix how certain range types are mapped into builtin unsigned int types.
4242 Remove 2 #includes. They cause errors (on Sony, at least),
4243 and aren't needed (they wern't in earlier versions).
4245 print_address_symbolic should never demangle labels
4246 (since it prints *assembler-level* labels).
4248 [This was superseded by the change to printcmd below.]
4251 Add some "volatile" return types to avoid warnings.
4252 If MISSING_VPRINTF add vprintf function and not just macro
4253 (since vprintf is used in printcmd.c).
4255 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
4256 (The latter isn't grokked by some PCC-based compilers.)
4258 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
4260 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
4261 * nindy-share/coffstrip.c
4262 Added some forward declarations (otherwise, gcc complains
4263 about implicit extern redefined as static).
4265 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
4267 Changes inspired by Per Bothner:
4268 * printcmd.c (print_address_symbolic): Take additional parameter
4269 specifying whether to demangle.
4270 (print_address): Pass in asm_demangle to control demangling.
4271 (print_address_demangle): New fn, takes explicit arg to control
4273 * utils.c: Add new vars demangle and asm_demangle, and let them
4275 (fputs_demangled): If !demangle, just print the argument.
4276 (fprint_symbol): If !demangle, just print raw symbol.
4277 * valprint.c (val_print): Call print_address_demangle rather than
4278 print_address, to cause demangling to depend on the global
4279 rather than assembler-level demangling setting.
4280 * WHATS.NEW, gdb.texinfo: Document.
4282 * main.c (show_command): Show all settings if no arg.
4283 (initialize_main): Make "info set" the same as naked "show".
4284 * command.c (cmd_show_list): Handle prefix commands in the
4285 list, and print the name of the setting as well as its English
4286 description and value.
4288 Allow gdb functions to specify where a line should wrap if it
4289 exceeds the size of a terminal line. Use it to make the output
4291 * utils.c (set_screen_width_command): New fn, mallocs a buffer
4292 of the right size when screen width changes.
4293 (set_screensize_command, screensize_info): Remove #if 0'd fns.
4294 (wrap_here): New fn, indicates a point in the output where we
4295 should wrap the line rather than just letting it overflow at a
4297 (fputs_filtered): Implement wrapping.
4298 (n_spaces): New fn, returns a pointer to N spaces.
4299 (print_spaces_filtered): Use n_spaces.
4300 * defs.h (n_spaces): Declare.
4301 * stack.c (print_frame_info): Wrap with 4-space indent after
4302 fn name and before filename and line number.
4303 * printcmd.c (print_frame_args): Wrap with 4-space indent
4304 before each argument name is printed.
4305 * valprint.c (value_print): Wrap with no indentation before
4307 (val_print_fields): Wrap with indentation relative to nesting
4308 level before each field name.
4309 (val_print): Wrap with nesting indentation before array elements.
4310 * command.c (do_setshow_command): Avoid extra newlines,
4311 wrap with 4-space indent around values printed, end with period.
4312 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
4314 * breakpoint.c (breakpoint_1): Implement addressprint for
4315 "info breakpoints" display. Change file name and line number
4316 format to " at file:nnn" rather than " (file line nnn)".
4317 * gdb.texinfo: Document.

4322 Frozen for gdb-3.92.6 release.
4324 README, WHATS.NEW: Update for 3.92.6 release.
4326 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
4327 coffread.o from configs since it is now built by default.
4328 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
4329 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
4330 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
4331 from configs since it is now built by default.
4333 Makefile.dist: Update for release 3.92.6. Handle files that
4334 have been moved to ../include, ../getopt, or ../bfd. Add
4335 saber.suppress and tests directory. Add config.status to
4336 the release (it will say "none").
4338 coredep.c: Minor formatting fixes.
4340 These changes were made in early December but only checked in now:
4341 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
4342 nindy-share/nindy.c: lint
4343 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
4344 register values coming back from the target; we store values
4345 in target byte order everywhere.
4347 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
4349 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
4351 * valprint.c (cplus_val_print, val_print_fields): New functions,
4352 which print C++ objects. They conspire to avoid printing a
4353 virtual base class more than once, following all the twists and
4354 turns of C++ virtual base rules.
4355 (val_print): Call the above rather than do it by hand.
4357 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
4358 symbol file, not for added files like shared libs. This really
4359 needs to be generalized to a timestamp per file.
4361 * core.c (cleanup_core): Avoid coredump if no core file.
4363 * config.gdb: Accept -host or -target in place of +host or
4366 * coffread.c (find_linenos): Avoid desupported BFD interface
4367 to line numbers. We still read them manually rather than using
4368 BFD's "generic" features.
4370 * gdbrc.tex, threecol.tex: Add GDB reference card and its
4372 Makefile.dist: Add refcard to OTHERS list for creating tar files.
4374 * Makefile.dist: Eliminate use of $< in explicit targets.
4376 * readline/Makefile: Use $< rather than $*.c, which does not
4377 include the VPATH in GNU Make.
4379 * tconfig/i960-bout, tconfig/i960-coff: These are identical
4380 copies of tconfig/i960, added for global configuration
4381 compatability. All i960 versions can read both coff and b.out.
4383 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
4384 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
4387 * TODO: Think of more things to do.
4389 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
4391 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
4392 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
4393 64-bit float conversion.
4395 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
4396 equivalent to sun?os4 so global config works.
4398 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
4400 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
4402 * main.c: Only declare linesize once; declare pagesize not at
4403 all, since it is never used.
4404 (main): Clear newly allocated line before it is used.
4406 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
4408 Further stabilization for the Intel 960.
4410 * Makefile.dist: Parameterize the location of the "include"
4411 and "bfd" directories, as well as "getopt". Add symfile.c.
4412 Link in both dbxread and coffread. Fix up "make depend" to
4413 rewack the locations of include, bfd, and getopt in its output.
4415 * README: Document moving include files, improve some of
4418 * coffread.c: Move common code out to symfile.c. Change
4419 symbol_file_command style interface to use new *_symfile_init
4420 and *_symfile_read interface under BFD. Use BFD internal
4421 info to locate line table, symbols, etc.
4423 * core.c (core_fetch_registers): Rename to get_core_registers
4424 to avoid confusion with fetch_core_registers.
4425 (register_addr): Move to coredep.c, which is already machine
4426 dependent. This leaves core.c pretty clean of dependencies.
4428 * coredep.c (register_addr): Accept this routine from core.c.
4430 * dbxread.c: Move common code (with coffread.c, etc) into new
4431 symfile.c. Each psymtab now contains a pointer to the
4432 format-dependent function that knows how to read it in. Make
4434 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
4435 (process_one_symbol): Add code to complain about a "compiler bug
4436 we muzzle here", if we actually see it.
4438 * eval.c (evaluate_subexp): Insert missing "break" statements
4439 in code that determines whether a variable is an lvalue in
4440 memory, register, or whatever. I detected this via a compiler
4441 bug in which it *almost* mashed out the whole switch statement.
4443 * gdb-int.texinfo: Add minor sections on configuring gdb for
4444 release, and about the README file.
4446 * infcmd.c (registers_info): Fix formatting somewhat. Still
4447 not as pretty as before, but it handles byte swapping.
4449 * remote-nindy.c: If data cache routines are interrupted while
4450 waiting for the remote end, be sure that any uninitialized cache
4451 blocks are on the free list, not on the valid list!
4453 * symfile.h: Flesh out this header file with all the various
4454 routines and variables that have been merged in from dbxread.c
4455 coffread.c, and symtab.c to symfile.c.
4457 * symfile.c: New file, containing code common to dbxread.c,
4458 coffread.c, and some code from symtab.c. All generic code for
4459 reading symbol files should be in here now.
4460 (unrecord_misc_function): Remove unused function.
4462 * symtab.h: Remove file-reading things to symfile.h.
4464 * symtab.c: Remove file-reading things to symfile.c.
4466 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
4467 to decode i960 fault types.
4469 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
4470 target.c: Change type of the "resume" function from int to void,
4471 since its result was never used.
4473 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
4475 * main.c: Replace "stupid" with "caution"; you now "set caution
4478 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
4480 * infcmd.c (do_registers_info): Call val_print to deal with the
4481 byte order of the registers being printed. FIXME, this makes
4482 the formatting of the output uglier.
4484 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
4485 defined, call it for signals the debugger doesn't itself use.
4486 The i960 uses this for more detailed fault information.
4488 * remote.c (remote_open): If arg is null, print help rather than
4491 * sparc-xdep.c (register_valid): Avoid declaring size, since
4492 various modules will think of various sizes depending on the
4493 architecture of their tm-file. FIXME, we need protection against
4494 actually entering one of those modules, which would clobber
4495 storage if not for the target architecture compiled into gdb.
4497 * stack.c (up_command, down_command): Always print the frame
4499 (up_silently_command, down_silently_command): New commands
4502 * i960-pinsn.c (reg), i960-tdep.c: Lint.
4504 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
4505 more parameters than it used to.
4507 * findvar.c (registers): Increase slop to 256 bytes, which should
4508 protect us against even most RISC machines with large register
4510 (locate_var_value): Move declaration inside related ifdef.
4512 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
4513 throughout, to avoid throwing away buffered input from the board.
4514 (nindy_wait): Supply_register takes addr_of_value, not value.
4515 (i960_print_fault): Renamed from i80960_fault.
4516 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
4517 (nindy_store_registers): Avoid regs_changed stuff, just stuff
4519 (nindy_create_inferior): Don't bother to write PC_REGNUM since
4520 we can set the PC in the call to proceed(). Unpush nindy_ops
4521 before pushing it on top, to avoid message to user. Eliminate
4522 commentary from Unix machines that just misleads here.
4523 (reset_command): Fix error message to suggest target command.
4525 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
4527 Release 3.92.5 as frozen.
4529 Stabilize the merged release...with help from lint, Saber C,
4532 Everywhere: Add include files needed to declare return types
4533 of functions called.
4535 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
4537 * breakpoint.h: Add undeclared breakpoint functions, and some
4538 functions for display handling since I couldn't think of a better
4541 * breakpoint.c (insert_breakpoints): Make code for disabling
4542 shared library bkpts more likely to work. It's used when we
4543 rerun a program and stop before the shared library has been
4545 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
4546 cast from pointer, so it squeezes through catch_errors.
4547 (bpstat_stop_status): Fix logic broken some time ago. We now
4548 always create a bpstat if the stop address matches a breakpoint,
4549 even if we don't stop there -- just like the old code used to do
4550 before I got my fingers into it (sigh).
4551 (breakpoint_1): Print "ignore count" after "stop only if"
4552 condition, since that's how it actually works.
4553 (mention): Handle watchpoints as well as breakpoints.
4554 (watch_command): use set_raw_breakpoint and mention to do most
4555 of the work (and initialize all the fields!). Only pass one
4556 arg to parse_c_expression, since that's all it takes.
4558 * command.c (not_just_help_class_command): Rename arg to args
4559 since we ignore "unused argument" warnings on vars named "args".
4560 inflow.c (child_terminal_info): ditto.
4561 infptrace.c (kill_inferior): ditto
4562 main.c (catch_errors, version_info, quit_command, pwd_command,
4563 source_command, dump_me_command, editing_info,
4564 set_history_size_command, set_history, show_history,
4566 stack.c (locals_info): ditto
4567 target.c (target_files_info): ditto
4568 valprint.c (set_input_radix, set_output_radix): ditto
4570 * core.c: Remove old variables for handling core and exec file
4571 sections (data_start, data_end, stack_start, stack_end,
4572 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
4573 text_end, exec_data_start, exec_data_end, text_offset,
4574 exec_data_offset, data_offset, stack_offset). They're
4575 superseded the more general build_section_table and
4577 (get_exec_file): Mention the `file' command.
4578 (read_memory_check): Rename to memory_error, and only call it
4579 in the case of an actual error.
4580 (read_memory, write_memory): call memory_error.
4581 (core_fetch_registers): Register section name is ".reg".
4583 coredep.c: Remove a bunch of crud now that all this file does
4584 is pull the registers out of a core file.
4585 (fetch_core_registers): Rewrite to actually work, I hope.
4587 dbxread.c: Use a.out.gnu.h, not system a.out, now.
4588 Replace index() with strchr(). Remove all the pre-BFD macro
4589 definitions for accessing the symbol file.
4590 (struct dbx_symfile_info): Encapsulate the information that
4591 dbx_symfile_init needs to pass to dbx_symfile_read in this
4594 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
4595 dbx_symfile_discard): Rearrange symbol file reading to divide
4596 the format-specific part from the format-independent part,
4597 leaving the format-independent part such as file name expansion
4598 and opening in symtab.c. This replaces
4599 partial_symbol_file_open and partial_symbol_file_read.
4600 Symbol_file_read, add_file, add_file_target_command,
4601 add_file_addr_command move to symtab.c. Pass an explicit
4602 "mainline" flag for when reading the main symbol table, rather
4603 than relying on the offset address to be zero or nonzero.
4605 (dbx_symfile_read): Don't allow void *'s to be printed as
4607 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
4608 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
4609 macro" debug version really work.
4610 (read_dbx_symtab): Remove unref'd parameter inclink.
4611 Avoid swapping N_SLINE symbols, for speed.
4612 Merge N_TEXT!N_EXT case with the other external symbol
4613 definitions' case. Add comments.
4614 (start_psymtab): Allocate the symfile name in the psymtab on
4615 the psymbol_obstack, rather than using the caller's storage.
4616 (end_psymtab): Only allocate a dependencies list if there are
4618 (psymtab_to_symtab_2): Use BFD when reopening file to read
4619 its symbols for real.
4620 (read_struct_type): Add FIXME comments where it needs work
4622 (read_huge_number): Add FIXME about overflows.
4623 (read_range_type): Add FIXME about comparing a long to 1<<32.
4625 * coffread.c: Minor changes to move things closer to the new
4626 regime with symtab.c and dbxread.c Major work is still needed
4629 * exec.c (exec_file_command): Remove old variables (see core.c
4631 (xfer_memory): If memory transfer is right at the end of a
4632 section, don't lose.
4634 * findvar.c (get_saved_register): If value is in a real
4635 register, LVAL is lval_register, not lval_memory.
4637 frame.h: Declare print_sel_frame and record_selected_frame.
4639 gdb-int.texinfo: New file, for GDB internals documentation.
4640 Very simple, unformatted doc of cleanups is there for now.
4642 gdbcore.h: Remove obsolete variables that described a.out
4643 section addresses and offsets. (See core.c above.)
4644 Declare fetch_core_registers and registers_fetched.
4646 getopt.c: Declare char *alloca(); even on SPARC.
4648 infcmd.c (run_command): Call target_kill rather than
4650 (step_command, next_command, stepi_command, nexti_command):
4651 Declare from_tty parameter even though we don't use it.
4652 (run_stack_dummy): argument BUFFER is a char array, not
4653 a pointer to REGISTER_TYPE.
4654 (finish_command): using_struct_return needed a value *,
4655 not a struct symbol *.
4657 * infptrace.c (child_xfer_memory): To avoid dependency on
4658 where sections are in memory, try PT_WRITE_D and if that fails,
4659 try PT_WRITE_I. Most Unixes don't care which you use.
4661 * infrun.c (step_resume_break_shadow): Change to array to
4662 match other breakpoint shadow storage.
4663 (clear_proceed_status): Pass address of bpstat to
4664 bpstat_clear, not the bpstat itself.
4665 (child_create_inferior): FIXME comment about if the child
4667 (start_inferior): Remove old function.
4668 (child_open): Use target_kill rather than kill_inferior.
4669 (wait_for_inferior): Ditto.
4670 (insert_step_breakpoint, remote_step_breakpoint): Use
4671 new step_resume_break_shadow.
4673 * inftarg.c (child_wait): If all child processes die,
4674 pretend that the one being waited for exited with signal 42.
4676 * main.c (command_line_input): When scanning for comments,
4677 don't coredump on unclosed quotes.
4678 (quit_command): Use target_kill rther than kill_inferior.
4679 (_initialize_main): Rename class_user from "user" to
4682 * printcmd.c (print_command_1): Initialize "fmt" if no format
4683 is specified by the user.
4684 (print_frame_args): Only add to args_printed if we are
4685 actually fetching args from the stack (avoiding undefined
4687 (_initialize_printcmd): Remove bogus \{ from string.
4689 * remote-eb.c (eb_open): Avoid coredump on no argument.
4691 * remote-nindy.c: Bring out of Intel environment into new
4692 target environment. Remove all conditional compilation on
4693 I80960. Massive hacking throughout.
4694 (nindy_xfer_inferior_memory): New routine stolen from
4696 (nindy_create_inferior): New routine pieced together, probably
4697 not quite working yet.
4698 (nindy_ops): New target_ops struct for nindy.
4700 * remote-vx.c: Use write_memory rather than target_write_memory
4701 to get error checking.
4702 (vx_add_file_command, vx_open): Use symbol_file_add rather than
4704 (vx_create_inferior): Use target_terminal_ours...
4706 * signame.c (_initialize_signame): Always initialize, since
4707 we need the table for things other than psignal.
4709 * solib.c (solib_add): Use symbol_file_add, not add_file.
4710 (solib_address): Return boolean result rather than struct
4711 pointer which nobody else knows the type of.
4713 * sparc-tdep.c, valops.c: Use write_memory rather than
4714 target_write_memory, to get error checking.
4716 * stack.c (locals_info, catch_info, args_info,
4717 get_selected_block, frame_command, up_command): Use
4718 target_has_stack, rather than have_inferior_p or
4721 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
4723 * symfile.h: New file, defining the interface between the
4724 generic and object-file-specific symbol reading code.
4726 * symtab.c: Move generic symbol-reading interface to symtab.c,
4727 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
4728 table to map BFD targets to symbol-reading modules in GDB.
4729 Change index to strchr.
4730 (lookup_struct_elt_type): Use error() rather than hand-made
4731 simulations thereof.
4732 (lookup_partial_symbol): Speedup slightly when length == 0.
4733 (symbol_file_add): New function.
4734 (symbol_file_command): Call it.
4735 (symfile_open, symfile_init): New function.
4736 (add_file_target_command, add_file_addr_command): moved from
4739 * target.c (target_command): use target_kill.
4741 * target.h (target_files_info): Don't declare, never called
4744 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
4745 files to determine stack end address.
4747 * valarith.c (value_x_binop, value_x_unop): Change error message
4748 to be more useful. Pass proper argument to value_struct_elt.
4750 * valops.c (value_assign): FIXME comment that long long
4751 bitfields will break here.
4753 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
4754 Update `make saber_gdb' to work better.
4756 * TODO: A woman's work is never done.
4758 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
4759 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
4760 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
4761 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
4762 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
4763 valops.c, valprint.c, exec.c: Lint.
4766 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
4768 Continuing Intel 960 port merge of GDB.
4770 * Makefile.dist: Merge i960 "nindy-share" files. Rename
4771 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
4772 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
4773 Wack over "make depend" so it handles files in subdirectories
4774 vx-share, nindy-share, bfd, and in the current directory.
4776 * blockframe.c (get_prev_frame_info): Remove fatal error
4777 if stack not defined.
4779 * core.c (core_open, core_detach): New functions that handle
4780 the old "core-file" command as "target core" and "detach" instead.
4781 (core_file_command): Call them.
4782 (core_xfer_memory): Use common routine xfer_memory.
4784 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
4785 dbxread now uses bfd for everything but symbol reading itself.
4786 BFD internals are used to drag out the relevant file offsets.
4787 (partial_symbol_file_open): Change args all around for BFD.
4789 * symtab.c: Rename "value" to "val" everywhere, so we can
4791 (symbol_file_command): New command, moved from dbxread.c
4792 and coffread.c. It uses BFD to read the file, then vectors
4793 based on its type, to dbx or coff symbol readers.
4794 * symtab.h: Extern a few vars for symbol_file_command.
4796 * target.h: Breakpoint takes a char * save area, not a char **.
4798 * valprint.c (val_print): When unpacking bitfields, offset
4799 the address in gdb of the value, if it is declared with a shorter
4800 type. Remove the last "runtime kludge test" of host byte order.
4802 * utils.c: Remove old my_bfd_read routine.
4804 * stack.c (frame_info): Use target_has_stack. Print program counter
4805 register's actual name rather than "pc", since it's called the
4806 "ip" (instruction pointer) on the i960 (sigh).
4808 * target.c (target_command): Add command for selecting a target
4809 type and calling its open routine. This is used for initiating
4810 communication with a particular target, in a generic way.
4812 * tm-i960.h: Update for modern gdb. Remove semicolons from
4813 various macros. Handle reading struct return convention, and
4814 error-out attempts to return structs with the "return" command.
4815 Be sure gdb doesn't think we know how to call functions in the
4818 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
4819 to i960_xxx in lower case.
4820 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
4821 not being defined yet.
4823 * remote.c (remote_open): Call start_remote to initialize
4824 wait_for_inferior during open.
4825 (remote_xfer_inferior_memory): Return length written rather
4828 * remote-vx.c (target_command -> vx_open): Use new generic
4830 * remote-eb.c, inftarg.c, exec.c: ditto.
4832 * infrun.c: Fix comments.
4833 (attach_program -> child_open): Use new generic target command.
4834 (wait_for_inferior): Clear saved register values before target_wait,
4835 so target_wait can set some of them if convenient.
4837 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
4838 Return success indicator, not void.
4839 (child_xfer_memory): Avoid fetching initial word if we'll
4840 overwrite it anyway.
4842 * infcmd.c (attach_command): Use new generic target open routine.
4843 (_initialize_infcmd): Update doc on attach and detach commands.

4865 Merge Intel 960 port of gdb, continuing...
4867 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
4868 symbol_file_command): Pass from_tty arg to hush 'em up.
4870 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
4871 Add magic numbers for 960 COFF format.
4873 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)

4899 Thu Apr 19 09:54:28 PDT 1990
4900 Add 'reset' command.
4902 Wed Apr 18 09:48:07 PDT 1990
4903 After opening remote tty, wait for 1 second to go by without input
4904 from it before trying to talk to NINDY (fixes problems with the
4905 Heurikon HK80/V960E).
4907 Mon Apr 4 16:33:05 PDT 1990
4908 Some output was not being suppressed in 'batch' mode.
4910 Thu Mar 22 15:31:11 PST 1990
4911 Ask user if old symbol table should be deleted when new file is
4914 Allow user to run a program downloaded before gdb960 was brought up.
4916 Correct "exec-file" help message for i80960 context.

4943 Added 960CA disassembly support.
4945 To simplify maintenance:
4946 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
4948 - eliminated opcode.h: incorporates tables into i960-pinsn.c
4949 - moved 960-specific routines from i960-pinsn.c to i960-md.c
4950 - made disassembly interface identical to that in gdmp960.
4954 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
4956 * target.h: Allow targets to stack. Add target_has_memory,
4957 _registers, etc. Restructure memory access and "info files"
4958 to walk the target stack.
4959 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
4960 target.c: Change tables to match target.h.
4961 * inflow.c (child_mourn_inferior): pop child_ops.
4962 (generic_mourn_inferior): Use new has_stack flag.

4964 * inftarg.c (child_files_info): New "info files" regime.
4965 * remote-eb.c: New memory regime, new info files.
4966 * remote-vx.c: New memory regime, new info files. Now use
4967 separate targets for VxWorks attachment to machine, and
4968 actually running a process under VxWorks, since one has
4969 stack & execution & regs and the other doesn't.
4970 * remote.c: New memory regime, new info files.
4971 * sparc-xdep.c (fetch_core-registers): New memory regime.
4972 * target.c: New routines and support for stacked targets,
4973 new memory regime, new info files regime.
4976 Generalize section handling for an arbitrary number of sections,
4977 including use of the new BFD (binary file) library.
4978 * gdbcore.h: Add struct section_table.
4979 * exec.c (build_section_table): Iterate all sections and
4980 record what gdb needs to know about them.
4981 (exec_command): Use it.
4982 (exec_xfer_memory): Use the table.
4983 (exec_files_info): Print the table.
4984 * core.c (core_file_command, core_xfer_memory, core_files_info):

4992 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
4994 * inferior.h (attach_flag): Export.
4995 * infcmd.c (run_command): use new target_create_inferior.
4996 * infrun.c (child_create_inferior): Don't return result.
4997 * Makefile.dist (VERSION): 3.91.4.
4999 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
5001 * breakpoint.c (bpstat_num): Handle breakpoints which have
5002 since been deleted, such as temporary breakpoints.
5003 infcmd.c (program_info): ditto.
5005 * core.c (core_file_command): Display the frame where the core
5010 * remote-vx.c (target_command): Merge in target command from
5011 targ-vx.c. A few other cleanups.
5013 * TODO, Projects: Lots more stuff to do...
5015 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
5017 Massive changes to wall off the remote-debugging interface
5018 behind a function vector. The port to handle VxWorks targets
5019 is also part of this.
5021 All files: Replace references to renamed functions,
5022 remove references to remote_debugging, remove references to
5023 have_include_file, have_core_file in favor of target_has_stack,
5024 target_has_memory, etc.
5026 * Modularize the breakpoint interface.
5027 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
5028 a breakpoint instruction.
5029 breakpoint.c: struct breakpoint's shadow_contents now sized as
5031 (insert_breakpoints): Vector to target to install breakpoints.
5032 (remove_breakpoints): Vector to target here too.
5033 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
5034 sparc-tdep.c (single_step): Use new breakpoint interface for
5035 the single-step breakpoints.
5036 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
5037 New file, contains routines to insert and remove breakpoints by
5038 reading out the old contents and later replacing them. This is
5039 how ptrace breakpoints work, and many remote systems as well.
5041 * tm-vxworks68.h: New config file, overrides a few things for
5042 Wind River's preferences.
5044 * target.h: New file, for transfer vector used to talk to the
5045 inferior (child, attached, core, exec, remote, etc). All accesses
5046 to the thing being debugged should come through these vectors.
5047 target.c: New file, routines to handle transfer vector.
5048 (various files): Add transfer vectors XXX_ops for the various
5049 targets and pseudo-targets (core files, etc) we support.
5051 * breakpoint.c (bpstat_stop_status): Further explorations of
5052 watchpoints and why things don't work all the time.
5053 (bpstat_alloc): New fn to allocate a bpstat and chain it.
5055 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
5056 the local gdbinit if it doesn't already have it.
5058 * core.c (core_ops): add and install.
5059 Allow core debugging without exec file.
5061 * dbxread.c (free_and_init_header_files): Merge two fns.
5062 (end_symtab): Free named symbol table when a new version comes in.
5063 (read_dbx_symtab): Relocate all kinds of symbols with base
5064 address. First step toward handling different text, data, bss
5066 (add_file_addr_command): Renamed add_file_command.
5067 (add_file_command): Vector to remote handler.
5068 Add "load" as an alias for "add-file" command.
5070 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
5071 non-returning functions.
5073 * exec.c: Add exec_ops, and push it as a target when an exec
5076 * infcmd.c (run_command): Pass executable file name and arg list
5077 separately when starting an inferior. Permit "run" when no exec
5078 file is specified, for VxWorks.
5079 (detach_command): Move to child_detach in inftarg.c.
5081 * inftarg.c: New file. Unix-child-specific routines, and the
5082 child_ops structure.
5084 * inferior.h (registers): Export "registers" as the way for
5085 target dependent register handlers to find gdb's local copy of
5086 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
5087 since it is now used by places that want wait_for_inferior to
5088 handle the grunge but want to see every trap from the inferior.
5090 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
5091 Eliminate remote_debugging hooks in terminal handling.
5093 * infrun.c: Replace start_inferior with child_create_inferior.
5094 Move all the hair of Unix shells and ptrace idiosyncracies into
5095 child_create_inferior, so remote handlers don't have to deal.
5096 Remove running_in_shell. Rename stop_after_attach to
5097 stop_soon_quietly, and use it in a few other places where we want
5098 to just call wait_for_inferior and get control back on the first
5099 trap. trap_expected now never takes a value > 1.
5100 (init_wait_for_inferior): Initialize static vars when a new
5103 main.c (gdbinit): Add new hook for .gdbinit file name, let
5104 it be overridden by config files as GDBINIT_FILENAME.
5105 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
5106 Both of these are used for VxWorks gdb.
5108 mcheck.c: rename include file "gmalloc.c" to avoid problems
5109 with system include file "malloc.c".
5111 param-no-tm.h: New include file, same as param.h but does not
5112 include the default "tm.h" file. This is used in files where
5113 the target is known, e.g. remote-eb.c or sparc-xdep.c.
5115 param.h: Now just a shell that includes tm.h and param-no-tm.h.
5117 remote-vx.c: New file, VxWorks remote debugging support. Uses
5118 RPC routines that are shared with the target system, in directory
5121 remote.c: Vectorize remote interface.
5123 source.c: Globalize source_path, and make an alias "l" for "list"
5124 since we now have the "load" command.
5126 sparc-xdep.c: Use new param-no-tm.h.
5128 symmisc.c (free_named_symtab): Add new function from Wind River.
5129 However, ifdef it out for now while we think about what it should
5132 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
5134 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
5135 non-Unix-children handle this with their own code in the target
5138 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
5139 source and target lists. Add vx-share to default list of include
5140 directories. Add new files to src and target lists: mem-break,
5141 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
5142 ${srcdir} versions of munch and createtags are used.
5144 * valops.c (find_function_addr): Split out of call_function.
5145 (call_function_by_hand): Rename call_function; this function
5146 calls functions in the target by laboriously patching the target
5147 word-by-word with the right stack, args, regs, etc.
5150 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
5152 Handle AMD 29000 a bit better.
5154 * remote-eb.c (readchar): Mask received char log to make it readable.
5155 (remote_start): Pass arguments down to executing program.
5156 Make startaddr unsigned.
5157 infrun.c (start_inferior): Accept args, pass them to
5159 infcmd.c (run_command): Pass args down to start_inferior.
5161 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
5162 the target object file format.
5163 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
5165 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
5166 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
5168 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
5170 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
5171 * TODO: We did a few things, we have more to do though.

5179 (sparc_frame_find_saved_regs): Simplify and fix what we find.
5180 (sparc_push_dummy_frame): Simplify and fix what we push.
5181 (sparc_pop_frame): Slightly more hair here, deciding whether
5182 we are restoring a saved PC or returning to a return address in %i7.
5183 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
5185 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
5186 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
5187 * obstack.h (chunkfun): ditto.
5188 * defs.h (xmalloc, xrealloc): ditto
5190 * utils.c (quit): Grab the terminal from the child if necessary.
5192 * inflow.c (term_status_command): Rename to term_info, change
5195 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
5196 (is_delayed_branch): Speed up.
5197 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
5198 Still missing some float ops, and needs testing.
5200 * Support for input and output radixes other than base 10
5201 * defs.h (input_radix, output_radix): Declare.
5202 * expread.y (yyparse, parse_number): Handle changes of input
5203 radix, and ambiguous names-or-numbers in radixes >10.
5204 * printcmd.c (print_scalar_formatted): Print formatted hex
5205 numbers in varying column widths.
5206 * valprint.c (val_print): Use output_format to print scalar ints.
5207 (set_input_radix, set_output_radix, set_radix): Create.
5208 (set_output_radix): Set output_format from output_radix.
5209 (_initialize_valprint): add `set radix' but leave the others off.
5211 * main.c (execute_command): Let stupid questions be turned off.
5212 (_initialize_main): Handle "set stupidity", etc.
5214 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
5215 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
5217 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
5219 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
5220 bfd stuff is still screwed up, but with some manual work, it
5223 * breakpoint.c (bpstat_do_actions): Start over if a command
5224 proceeds the inferior, since the inferior will have stopped and
5225 will need to have its new stop-actions taken care of.
5227 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
5228 compiler fits, simplify it.
5230 * gdb.texinfo (directory command): Doc new dir command.
5231 source.c (directory_command): "dir" now puts things on the front
5232 of the path, moves dups up front, and handles multiple names
5233 on the command line, inserting each one in order. It also
5234 blows away cached line and full_filename info.
5236 * stack.c (backtrace_command): Skip "more stack frames follow"
5239 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
5240 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
5241 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
5242 The only odd one was Gould NP1, which had defined vprintf to
5245 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
5246 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
5247 variable, inspect_it.
5248 valprint.c (print_string, val_print): Use the global inspect_it
5249 to indicate whether to print in Epoch style or normal style.
5251 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
5253 * printcmd.c (call_command): add an alias for the "print" command
5254 which runs expressions and doesn't print the result if void.
5255 (print_command_1): implement it.
5257 * command.c: Remove #if 0'd code. Initialize all the fields
5258 in add_cmd (). Rename do_nothing_command to
5259 not_just_help_class_command, and make it externally visible.
5260 command.h: add user_commands to struct.
5261 * main.c (define_command): Don't overload c->function with a char
5262 string as well as a function pointer.
5264 * eval.c (evaluate_subexp): Reinstall tiemann changes to
5265 calling convention of value_struct_elt () that got dropped in
5268 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
5269 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
5271 * tm-sparc.h (POP_FRAME): replace some constants with defines.
5273 * sparc-xdep.c (store_inferior_registers): defer stores to regs
5274 until a good time (e.g. when we are about to run the child),
5275 saving ptrace calls.
5276 * infrun.c (proceed): handle DO_DEFERRED_STORES.
5277 * tm-sparc.h: define DO_DEFERRED_STORES.
5279 * sparc-xdep.c (store_inferior_registers): when storing float
5280 registers, don't store stack regs too. When storing the SP,
5281 however, DO store the stack regs too. This fixes a bug in which
5282 the dummy frame is not recognized when a call_function finishes,
5283 because its frame pointer (in the stack regs) was never
5285 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
5286 even though we don't know how to read them from an inferior.
5287 valops.c (call_function): Comment about storing SP.
5289 * infrun.c (save_inferior_status): Save away the original bpstat
5290 chain so it can be restored later. Install the copied version for
5291 use by whoever saved the status. It will be blow away by
5292 restore_inferior_status, and the original chain restored. This is
5293 important for people who have pointers into the original.
5295 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
5296 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
5297 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
5300 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
5302 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
5303 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
5304 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
5306 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
5308 * Merge Mike Tiemann's multiple inheritance changes from Sun.
5309 Store the baseclasses in a type struct starting from array element
5310 0 rather than from the unusual array element 1.
5312 dbxread.c: the above.
5313 (virtual_context): Add
5314 Read new debug information about which virtual function table
5315 a virtual function is from, and store it in fn_field.fcontext.
5317 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
5318 TYPE_FN_FIELD_STATIC_P.
5320 symtab.c: the above.
5321 valops.c: the above. Handle pointer casts of object *'s.
5322 (search_struct_method): Add.
5323 (value_struct_elt): First arg is now a pointer to a value, and is
5326 valprint.c: the above.
5327 values.c (value_virtual_fn_field): Add type arg. Handle
5328 offsetting to the proper object when calling virtual fns.
5330 (baseclass_addr): Add valuep arg.
5332 * README: Document the current state of BFD config (missing).
5333 * TODO, ChangeLog, Makefile.dist: Roll version.
5334 * WHATS.NEW: Add summary of changes since 3.5.
5336 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
5338 * dbxread.c (read_struct_type): Clear bit vectors whenever
5340 symtab.c (B_CLRALL): define.
5342 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
5343 using == rather than =. Huh... This fixes the dreaded problem
5344 wherein builtin_type_int becomes TYPE_CODE_FLT.
5346 * core.c (info_files): Show the inferior pid.
5348 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
5349 already knows how to look in the source directory.
5351 * Remove psymtab hair from many places. Remove duplicated code
5352 for searching symbol tables. Hide psymtabs from most places.
5353 Make it fast to get from a psymtab to its symtab.
5355 blockframe.c (blockvector_for_pc): Remove psymtab hair.
5356 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
5357 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
5358 dbxread.c: export psymtab_to_symtab, make it work if called N times.
5359 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
5360 new symtab completely. New psymtabs get symtab pointer
5361 initialized to zero. Remove MI warning printf.
5362 symtab.h: Comments. Add psymtab to symtab pointer.
5363 (PSYMTAB_TO_SYMTAB): New macro.
5364 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
5365 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
5367 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
5369 (print_frame_info): Avoid special-casing symbols that have not yet
5372 * source.c (open_source_file): Quick path if we have already
5373 located the source file by its full name.
5375 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
5376 find_pc_psymtab. When a name is found in the misc function
5377 vector, search the symbol table for its mangled name, not the
5378 name that the user typed.
5380 * bfd.h: Fix missing comment terminators, make #endifs match.
5382 * valarith.c (value_less): Handle unsigned int comparisons.
5383 Add FIXME about pointer compares, which assume host and target
5384 pointers are the same.
5386 * command.c (do_nothing_command): lint
5387 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
5388 fix comments on debug symbol format for visibility. Actually set
5389 visibility of symbols.
5390 main.c (echo_command): lint; use <readline/history.h>.
5391 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
5392 obstack.h (_obstack_blank): Rearrange pointer math to avoid
5393 pointing past end of allocated memory; saber complains.
5394 obstack.h: Declare the external functions that we use.
5395 valarith.h: use <string.h>
5396 solib.c (solib_add): lint.
5398 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
5400 * main.c (initialize_main): Default info_verbose to off, now that
5401 symbol reading is fast.
5402 (quit_command): Avoid clobbering exec_bfd while quitting.
5404 * Initial BFD (binary file diddling library) merger:
5405 coffread.c: Change AOUTHDR to struct exe_hdr.
5407 core.c: initialize initialized data at compile time.
5408 (core_file_command): Move from coredep.c, convert to bfd.
5409 (xfer_core_file): Convert to bfd.
5410 exec.c (exec_file_command): use bfd routines.
5412 mips-tdep.c: Remove exec_file_command and friends.
5415 * coredep.c: (fetch_core_registers) Convert core_file_command to
5416 fetch_core_registers.
5417 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
5419 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
5420 (my_bfd_read): More bogosity, which I don't think we call.
5421 (program_name): Remove this atrocity asap!
5423 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
5426 values.c: allocate_repeat_value was not clearing the
5427 optimized_out field.
5428 (value_static_field): minor stylistic fix (wrong macro was used).
5429 valops.c (value_struct_elt_for_address): didn't work for C++
5432 * signame.c (_initialize_signame): Initialize signal names once.
5434 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
5435 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
5436 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
5438 * remote-eb.c: Support user-settable baud rates on the serial port.
5440 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
5442 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
5444 * tconfig/sun3os4: Remove warning about native assembler,
5445 since it also occurs in the xconfig file.
5447 * findvar.c (registers): Allocate some slop after `registers'
5448 to prevent stray accesses from trashing the next variable.
5450 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
5451 on the sun-3, by changing the #ifdef from `sun3' (which is not
5452 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
5453 vars, which happened to follow `registers' in the executable.
5455 * readline/history.c (history_search): Heed gcc-2's advice
5456 and parenthesize && inside ||).
5458 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
5459 tm-29k.c: Insert FSF copyright headers.
5461 * remote-eb.c: Better comments.
5463 * Makefile.dist: Update to 3.91.6.
5464 * TODO: note PREPARE_TO_STORE problem.
5466 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
5468 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
5470 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
5472 * infrun.c (wait_for_inferior, at end): Don't set up
5473 prev_* if the inferior no longer exists.
5475 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
5476 CANNOT_EXECUTE_STACK.
5477 valops.c (call_function): Use it.
5479 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
5481 * inferior.h (PC_IN_CALL_DUMMY): New macro.
5482 infrun.c (wait_for_inferior, 2 places): Use it.
5484 * values.c (value_being_returned): Only use
5485 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
5487 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
5488 right thing for remote-eb.c.
5490 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
5491 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
5493 * blockframe.c: Put get_frame_saved_regs inside #if !defined
5494 (FRAME_FIND_SAVED_REGS).
5496 * findvar.c ({fetch,store}_registers): Check for
5497 REMOTE_{FETCH_STORE}_REGISTER macro.
5499 * findvar.c (get_saved_register): Add argument lval and
5500 change meaning of argument addr.
5501 findvar.c: Change calls to get_saved_register to reflect
5502 new calling convention.
5503 valops.c (value_assign): Use get_saved_register instead of
5504 find_saved_register.
5506 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5508 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
5509 an (uninitialized) pointer to one. Use "&" when passing it
5512 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5514 * coffread.c (getfilename): Use DGUX x_offset and x_name if
5517 * coffread.c (symbol_file_command): Put semicolon after
5519 Put safe_to_init_tdesc_context in #if defined (TDESC).
5520 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
5521 coffread.c: #include <sys/stat.h>.
5522 (read_coff_symtab): Typo: in_source_files -> in_source_file.
5523 Add missing ')' in check for "lc%" and friends. Remove
5525 Declare read_one_sym() at top of file.
5526 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
5527 MC68WRMAGIC can have the same value without causing a duplicate
5530 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
5532 * Allow a Makefile to be built without building the
5533 tm and xm file links that screw up builds in subdirectories.
5534 This is done with `config.gdb none', then you can do things
5535 like `make gdb.tar.Z'.
5536 * tconfig/none: Config file for no target system
5537 * xconfig/none: Config file for no host system
5538 * config.gdb: If no TM or XM files are called out by the
5539 host or target file, don't make links for them.
5541 * cplus-dem.c: Add documentation.
5543 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
5544 simple error, so the user's gdb doesn't crash due to some object
5545 file problem (e.g. somebody is rebuilding the file out from under
5548 * printcmd.c (print_address_symbolic): demangle the symbol.
5550 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
5551 Motorola copyrights in it. Make "make gdb.tar.Z" work.
5552 (alldeps.mak): sort and uniq all results from this; duplicates
5553 hose gdb.tar.Z link building. Remove RCS files from
5554 tconfig and xconfig. Add config files for sun386. Add
5555 a few odd files to OTHERS and HFILES.
5557 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
5559 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
5560 Roll version number to 3.91.5. Make lint work in bindir.
5562 * README: Document cross-debugging and new file structure.
5564 * blockframe.c: Lint. Include "value.h" to declare read_register.
5565 (find_pc_partial_function): remove duplicate line.
5567 * command.h: Lint. Declare error_no_arg and dont_repeat.
5569 * tm-news.h: Remove inadvertently duplicated stuff.
5571 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
5572 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
5574 * config.gdb: Allow `config.gdb host target' form. Clean
5575 up previous change that printed bogus messages when you just said
5578 * core.c: #include "command.h" for lint.
5581 * main.c: Remove some casts of enums. Lint.
5588 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
5590 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
5591 read it from memory. This will allow us to save ptrace calls
5592 eventually. Changed caller single_step too.
5594 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
5595 that we aren't going to use, saving many ptrace calls, especially
5596 when watchpointing or single stepping. Use some #define's for
5598 (store_inferior_registers): Ditto.
5599 (core_file_command): Use some #define's for constants.
5601 * tm-sparc.h: Add #define's for some register numbers, so we
5602 can eliminate the use of random constants in sparc-xdep.c.
5604 * stack.c (frame_command, print_frame_info, up_command,
5605 down_command) Remove frame_changed, since it
5606 causes a bug and doesn't seem to do anything useful. In some
5607 places it was used as a flag, in others as a stack level (?).
5609 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
5610 default is to use the portable (vprintf) version rather than the
5612 * xm-news.h (MISSING_VPRINTF): Add.
5614 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
5616 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
5618 * Remove stuff that forces -Bstatic linking of gdb, and warnings
5619 about linking debugged programs -Bstatic in the sun?os4 config
5620 files in tconfig and xconfig subdirectories.
5622 * main.c (main): Remove unreached exit(0) now that we exit
5625 * Create TODO file for online bug list. There are too many
5626 "little" bugs to keep track of on paper.
5628 * Change Projects file to refer to bug-gdb@cygnus.com
5629 rather than kingdon@ai.
5631 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
5633 * Makefile.dist (VERSION): 3.91.4 now.
5635 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
5636 (condense_misc_bunches): Add sanity check that misc_count is
5637 the same as the number of symbols in the bunch.
5639 * coffread.c: rename init_misc_bunches. Pass an argument
5640 to condense_misc_bunches (a zero).
5642 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
5643 every time we are called; don't rely on our caller to do it.
5644 (add_file): Remove call to init_misc_bunches.
5646 * mipsread.c: Only warn, don't error, if unknown symbol types.
5647 This keeps an old gdb from falling on its face if it sees newly
5648 extended symbol info. Rename init_misc_bunches.
5650 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
5652 * Merge in changes from Per Bothner for DECstations and other
5653 MIPS stuff. The rest is Bothner speaking:
5655 The next message is a merger of Alessando Forin's mips port with
5656 mine. I've tried to use my good if biased judgment to get
5657 the best of both. It *does* need testing.
5659 Some of the changes are general, *not* mips-specific.
5662 Didn't believe in little-endian bit order.
5663 There are still inconsistencies about whether flags
5664 like BITS_BIG_ENDIAN are integer (#if ...) or
5665 boolean (#ifdef ...). I tried to paper over them.
5667 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
5668 Moved some misc_function code that was common to
5669 {dbx,coff,mips}read.c to symtab.c.
5670 In the process, I think I cleaned things up a bit.
5671 At the same time, moved obsavestring and obconcat to symtab.c.
5674 Removed obsolete condense_addl_misc_bunches (use
5675 condense_misc_bunches(1) instead).
5678 Needed to include <sys/dir>, at least on DECstations.
5680 valops.c, mips-tdep.c, tm-mips.h:
5681 Added PUSH_ARGUMENTS macro to support funny argument-pushing
5682 conventions (when STACK_ALIGN is insufficient).
5683 Needed on mips, where doubles need 8-byte alignment,
5684 but ints only need 4.
5687 Removed cruft that was not being used.
5688 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
5691 Print $ before register-names (I think that makes things a little
5693 Never print two instructions, even if one delays.
5694 Removed hex-disassemble set_cmd. (This is not mips-specific,
5695 so I think the argument is whether it is generally worthwhile or not.
5696 I'm inclined to think not, given how easy it is to
5697 convert between radixes in gdb.)
5700 This is basically Alessando's code.
5701 It doesn't use obstacks; I changed it to use obstacks
5702 in a few minor places where using malloc causes a
5703 memory leak. (Probably, more places could/should be changed.)
5704 I added record_misc_function where it was missing.
5705 In symbol_file_command and add_file_command, I tried
5706 to make the code consistent with more recent versions.
5707 Minor sylistic changes in parse_procedure.
5708 Make a .gdbinfo. psuedo-symbol point back to the real
5709 procedure symbol (using the isym field).
5712 This is basically from my port, but with a lot of details
5713 and a number of routines merged in from Alessando's version.
5714 I basically used my code "raw" backtrace (use heuristics
5715 from the actual code, rather than symbol table info) - though
5716 the idea is Alessandro's. I feel my code is a little cleaner
5717 here, particularly in being a little more flexible, such as being
5718 able to handle gcc-produced code (which it now can).
5719 It also doesn't do frame caching (which is not useful
5720 more recent gdb versions).
5721 I also used my code for push_/pop_dummy, more or less.
5722 I tried to incorporate AF's code for testing sigtramp
5723 while backtracing; I probably got it wrong.
5724 Added mips_print_register, which tries to scrunch as much
5725 information as possible on a screen...
5726 Removed the skip-prologue set_cmd. As with hex-disassemble (see
5727 under mips-pinsn.c), I don't see anything mips-specific here,
5728 and I don't see it being all that useful anyway.
5731 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
5732 Use more register names (rather than hard-cases numbers).
5734 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
5736 * Hack up 3.90.11 changes:
5738 * Makefile.dist (depend): parameterize $(GCC).
5739 Add solib.c and solib.o.
5740 (readline): Fix vpath for both absolute or relative SRCDIR.
5742 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
5743 Also, let the part I didn't understand at least compile so
5744 I can test the rest. FIXME.
5746 * dbxread.c: Fix thinko using strcmp.
5747 (init_psymbol_list): declare static.
5748 (partial_symbol_file_open): Comment cleanups better, avoid
5749 cleaning up the string table since the caller will do that.
5750 Move the stat for mod time into symbol_file_command, temporarily.
5751 (There should be a mod time for each symbol file, eventually,
5752 to control its rereading. FIXME.)
5754 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
5755 SunOS, which gives error for shared libs otherwise. (From
5756 Schaefer, probably FIXME needs work for portability.)
5758 * solib.c: Move #include "param.h" to work.
5759 Lowercase all the Uppercase Letters In the Messages.
5760 (find_solib): Clean up inferior_so_name for debug printouts.
5761 Allow no argument, to mean all shared libraries.
5763 * symmisc.c: include param.h to get CLEAR_SOLIB.
5765 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)

5811 Take code which is shared between symbol_file_command and
5812 add_file_command and put it into partial_symbol_file_{open,read}.
5813 Split add_file_command into add_file_command and add_file.
5814 Make psymtab_to_symtab read in the string table if the file
5816 Two new parameters to read_dbx_symtab and start_psymtab.

5836 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
5838 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)

5870 * Makefile.dist: Bump version to 3.91.3.
5872 * Clean up handling of breakpoint commands (somewhat).
5873 Prompted by Tiemann bug report "cont 10" doesn't work any more.
5875 inferior.h: Add breakpoint_proceeded to inferior status struct
5876 and globals; save it and restore it.
5877 (clear_breakpoint_commands): Cleanup, remove old #define.
5879 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
5880 (save_inferior_status, restore_inferior_status): handle it also.
5881 (proceed): Remove earlier code that set breakpoint_proceeded.
5882 It is now set only in clear_proceed_status.
5883 (clear_proceed_status): Cleanup, use bpstat_clear rather
5884 than clear_breakpoint_commands. No callers need the stop_bpstat
5885 between clear_proceed_status and proceed.
5887 infcmd.c: Add breakpoint_proceeded definition and comment.
5888 (cont_command, jump_command, signal_command): Move call to
5889 clear_proceed_status right next to call to proceed.
5891 breakpoint.c (bpstat_do_actions): Avoid clobbering our
5892 caller's argument while running down the chain of breakpoints.
5893 Use new variable "breakpoint_proceeded" to determine when
5894 a command that it executes moves the inferior past the
5896 (bpstat_clear): Handle NULL argument.
5897 (bpstat_clear_actions): Avoid useless call to
5898 breakpoint_auto_delete.
5899 (delete_breakpoint): Clean up bpstat's that are pointing to
5900 the deleted breakpoint from the stop_bpstat chain.
5901 (breakpoint_auto_delete): Simplify.
5903 * Clean up handling of EOF, error on stdin, etc. This was
5904 prompted by a network problem that caused gdb to go into an
5905 infinite loop filling up its malloc'd memory.
5907 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
5908 not clear_breakpoints_commands, which is now gone.
5909 (main): If command_loop returns (e.g. from EOF on stdin), do
5910 a quit_command (looping back to command_loop if quit_command
5911 doesn't really quit).
5912 (command_loop): check result from command_line_input and
5913 exit if it returns NULL, rather than passing the NULL to
5915 (gdb_readline): Free malloc'd result space before returning
5918 * utils.c (query): Handle C-d to mean "yes", just as if the
5919 input was not a terminal. Also avoid infinite loop if EOF
5920 occurs in mid-input-line before newline. This allows
5921 query to be used at EOF on stdin with reasonable results.
5923 * infrun.c (proceed): Set breakpoint_proceeded.
5925 * values.c (value_as_long): Avoid infinite recursion for enums.
5926 (_initialize_values): Fix typo in help msg (kingdon).
5928 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
5929 RL_LIB for linking. This allows -lreadline for linking
5930 and nothing for dependencies, once readline is a real library.
5932 * config.gdb: Jim Kingdon: give useful error message if the
5933 host or target type is not recognized.
5935 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
5936 it just defines it. Dumb, but deal with it.
5938 * Jim Kingdon suggests:
5939 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
5941 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
5943 * Makefile.dist (VERSION): Bump version # to 3.91.2.
5945 * Clean up Bothner's changes.
5947 * blockframe.c (clear_pc_function_cache): New function.
5948 * blockframe.c: remake cache_pc_function_* static.
5949 * dbxread.c (symbol_file_command): remove references to
5950 cache_pc_function_* variables.
5951 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
5952 * printcmd.c: Avoid kludging a global variable (addressprint)
5953 to avoid printing the address of a string twice. Instead,
5954 pass the format letter 's' down low enough that it can be seen
5955 to avoid this problem.
5956 (print_formatted): Pass format arg to value_print.
5957 (restore_addressprint): Remove function.
5958 (do_examine): Avoid hacking addressprint, cleanups and such.
5959 (print_frame_args): Add a comment to a Bothner change.
5960 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
5961 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
5962 to wipe out the values cached in blockframe.c.
5963 * symtab.c (find_method): Add comment saying how big you must
5964 allocate to be "big enough". Per being terse again.
5965 * valprint.c (val_print): Handle format letter "s" to print
5966 strings without addresses. Add comment to vtbl printing code
5967 which casts with wild abandon. Rearrange reference-printing
5969 @0xaddr: value (print w/addressprint)
5970 value (print w/~addressprint)
5971 @0xaddr (parameter lists w/addressprint)
5972 or nothing (parameter lists w/o addressprint)
5974 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
5976 * Merge more changes from Per Bothner:
5978 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
5979 annoying) that I tried to improve it. Here are my suggestions.
5981 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
5984 Do automatic de-reference when taking the address of a reference.
5986 Don't deref_ref when printing parameter lists.
5988 More attempts at treating refernences properly.
5990 In val_print, if deref_ref==0, don't print dangling " = ".
5992 Add COERCE_REF macro, which de-references an REF.
5994 * Merge changes from Per Bothner:
5996 * Fixed (Sony news)-specific configuration problems.
5997 * Fixed other problems with using vanilla pcc and libc (enum problems;
5998 assumption that vsprintf exists).
5999 * Some major speed-ups (finc_pc_partial_function now caches a match;
6000 parsing avoids duplicate symbol_lookup calls).
6001 * Changed handling of baseclasses (no longer use baseclasses field
6002 of struct type, use the first n_baseclasses fields instead).
6003 * Various minor changes/fixes, most C++-related.
6006 Cache the most previous match from find_pc_partial_function.
6007 (Save both low and high ends of matching function's pc range.)
6008 This speeds up the loop of infrun.c:wait_for_inferior quite
6009 a bit, and makes step/next commands much zippier.
6011 Added an enum->int cast (otherwise, some compilers barf).
6013 No longer set baseclass offset to 0, since multiple
6014 inheritance now mostly works.
6015 Added a number of casts, to shut up compiler warnings
6016 (after stabs where made enums, not ints).
6017 When discarding a symbol table (in symbol_file_command),
6018 must clear the cache introduced in blockframe.c.
6019 Don't convert $vtbl_ptr_type to vtbl any more.
6020 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
6021 Mask off sign bit emitted by g++ for virtual table offset.
6022 Set voffset to -1 (not 1) for static member functions.
6024 Changed parsing/lexing of names to avoid doing symbol lookup twice
6025 (once when lexing to determine symbol class, once for real).
6026 Now only call symbol_lookup once. Fields of 'this' win especially big.
6028 Subpress printing addr twice in the case of 'x/s addr'.
6030 lookup_basetype_type is no longer used.
6031 Add find_methods as recursive helper function to decode_line_1.
6032 This allows multiple inheritance to work.
6033 Also, once one or more matches has been found, do not look in
6034 base-classes. (Baseclass methods would be overridden, anyway.)
6036 Removed baseclasses array in struct type.
6037 Instead of using baseclasses[i], use fields[i-1].
6038 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
6039 Changed sign convention of voffset (previous was inconsistent).
6041 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
6043 Used to assume existence of vsprintf. Re-written to not need it
6044 if HAVE_VPRINTF is undefined.
6046 typecmp was too pessimistic. Made it less so.
6048 Don't print space after address.
6049 If vtable points to a misc symbol (with 0 offset), print it,
6050 since that indicates the actual class of the object.
6051 Changed ype_print_derivation_info to use new inheritance
6052 scheme (without baseclasses vector).
6054 In value_primitive_field, fixed some bugs left over from previous set of fixes.
6055 Also, changes needed because TYPE_BASECLASSES were removed.
6057 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
6059 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
6062 If there is no path set, and the symbols don't indicate what directory
6063 a file was compiled in, look in the current directory. But either
6064 a path or a known compilation directory will prevent this.
6067 Three independent bug fixes:
6068 * Remove the #if 0 block that breaks some stuff.
6069 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
6070 adapt gdb to either SunOS 4.0.* or 4.1.
6071 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
6074 Instantiate the class T when looking for methods in it. (Tiemann@sun)
6077 (type_print) Demangle the name being printed.
6078 (type_print_base) Handle botched demangling without coredump (tiemann).
6081 (check_stub_method): Document routine.
6082 (tiemann) fix bug for no-arg functions
6083 Avoid clobbering beyond end of malloc'd storage.
6084 Terminate the argument list properly.
6086 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
6088 * Changes merged by John Gilmore:
6091 In breakpoint_1, use new print_address_symbolic instead
6092 of find_pc_partial_function. (This forces use of assembler-level
6093 addresses, and avoids misleading non-mangled source-level names.)
6095 Generalize ansi argument such that -1 means skip arglist totally.
6096 Removed global variable print_ansi_qualifiers (which made
6097 code non-reentrant), in favor of extra explicit arguments
6098 to internal routines.
6100 Add new helper function print_address_symbolic.
6101 Use find_pc_misc_function instead of find_pc_partial_function
6102 (since we want assembler-level symbols here).
6104 Print unknown function as just "f (...)", not "f (...) (...)".
6105 Use new fputs_demangled explicitly.
6107 Fixed a typing violation (problem: value.h cannot be imported
6108 without renaming many variable in this file).
6109 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
6110 decode_line_1: Moved forward some never-reached code.
6111 Made decode_line_2 skip function prologues correctly.
6113 fputs_filtered should not demangle by default.
6114 Add new fputs_demangled to demangle on demand..
6116 Change value_struct_elt to use value_primitive_field (using recursive
6117 utility function search_struct_field). This allows foo.bar to work
6118 for multiple inheritance (so far only for data fields).
6119 Change check_field in the same way (recursive helper function
6120 to support multiple inheritance).
6121 (Note: there are more of these problems that I haven't fixed.
6122 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
6123 value_of_this: 'this' symbol name is now just "this", note "$this".
6125 Don't print static members.
6126 Avoid printing "members of <type>" if there are none.
6127 Simplified type_print_derivation_info by merging duplicate code.
6128 Remove useless blank lines in type_print_base (ptype command).
6130 Added declaration of new routine value_primitive_field.
6132 Added value_primitive_field which is generalized version of
6133 value_field that can handle multiple inheritance (non-zero offsets etc).
6134 Re-implemented value_field to call value_primitive_field.
6136 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
6138 * infcmd.c -- insert else to avoid 'delete env' coredump when you
6139 delete the whole environment. Karl Berry reported the bug.
6140 * source.c - fix openp to avoid //'s in filenames, which
6141 trigger an Emacs bug causing it to not be able to find files
6142 when running gdb in a window.
6143 * dbxread.c - zap the #if 0 that botches the add-file code.
6144 It seems to work a lot better without all the code commented out.
6146 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
6148 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
6151 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
6153 * Makefile - added a ${CFLAGS} to a couple of entries,
6154 added remote-sa.sparc.c
6155 * added remote.sa-sparc.c, a modification of remote.c
6156 which conducts a dialog directly with the SparcStation prom.
6157 * breakpoint.c, infrun.c, sparcdep.c added
6158 remote_insert_breakpoint(), and remote_remove_breakpoint()
6159 to breakpoint.c instead of directly writing breakpoint instructions.
6160 * sparcdep.c on remote_debugging,there is no need
6161 to remove signle step breakpoint instructions.
6162 * main.c added "-epoch" flag and "int epoch_interface" to main.c
6164 * printcmd.c - epoch interface sends lisp expressions to open up
6165 epoch windows on inspection.
6166 * valprint.c - added arrayprint, and addressprint and made adding
6167 format controls easier
6168 * wait.h added a couple of undef's because we were getting
6169 complaints about WSTOPSIG and WTERMSIG begin redefined.
6172 Wed Jul 4 05:27:51 1990 Michael Tiemann (tiemann at masham)
6174 * symtab.c (decode_line_1): Add support for handling method stubs

6179 * values.c (baseclass_addr): Run loop from INDEX+1 to
6180 N_BASECLASSES; otherwise, we can still get into a loop.
6181 @@ This should be restructured to use a cleaner search strategy.
6183 Sun Jul 1 12:28:51 1990 Michael Tiemann (tiemann at masham)
6185 * dbxread.c (define_symbol,read_type): Grok GNU C++'s new
6186 abbreviation "Tt" for tags which have the same name as their
6189 Fri Jun 29 01:03:46 1990 Michael Tiemann (tiemann at masham)
6191 * symtab.c (list_symbols): add ability to set breakpoints on all
6192 the functions which match a particular regular expression.
6194 Tue Jun 26 04:26:29 1990 Michael Tiemann (tiemann at masham)
6196 * cplus-dem.c (cplus_demangle): New parameter ANSI says whether we
6197 should print ANSI qualifiers (such as `const' and `volatile').
6198 All callers changed to call with ANSI == 1, except from
6199 `check_method_stub', which uses old-style syntax.
6201 * symseg.h (struct fn_field): Remove unneccessary `args' field.
6202 * symtab.h (TYPE_FN_FIELD_ARGS): Redefined.
6204 * values.c (check_stub_method): New function.
6206 * cplus-dem.c (do_type): Handle "long long" (encoded as 'x').
6208 * dbxread.c (read_type): Handle new GNU C++ method type stubs.
6209 * valprint (type_print_base): Ditto.
6211 * symtab.c (gdb_mangle_typename): New function.
6213 Tue Jun 5 00:18:43 1990 Michael Tiemann (tiemann at gzilla)
6215 * breakpoint.c (catch_command): New function. Provides a
6216 mechanism to set breakpoints based on catch clauses.
6217 (disable_catch): Similar, but disables breakpoints on catch
6219 (delete_catch): Similar, but deleted breakpoints on catch clauses.
6221 Sun Jun 3 22:54:08 1990 Michael Tiemann (tiemann at gzilla)
6223 * blockframe.c (blockvector_for_pc): New function.
6224 * blockframe.c (block_for_pc): Changed to call
6225 `blockvector_for_pc' and get the block itself.
6227 * stack.c (catch_info): New function. Prints info about
6228 exceptions which can be caught in the current frame.
6229 * stack.c (print_frame_label_vars): New function. Similar to
6230 `print_frame_local_vars'.
6231 * stack.c (print_block_frame_labels): Prints out labels that are
6232 defined in this frame. These labels are exceptions that can be
6235 * dbxread.c: Updated to handle N_CATCH symtab types.
6237 Thu May 3 22:10:00 1990 Michael Tiemann (tiemann at teacake)
6239 * valprint.c (everywhere): TYPE_NAME (TYPE) no longer comes in the
6240 form "struct ..." for GNU C++. Don't flush any part of TYPE_NAME
6241 when printing the type.
6243 Wed May 2 22:43:04 1990 Michael Tiemann (tiemann at teacake)
6245 * valprint.c (val_print): Use `baseclass_addr' to access the
6246 baseclasses pointed to via the derived class object at VALADDR.
6248 * values.c (baseclass_addr): New function. Casts derived pointers
6249 to baseclass pointers taking virtual baseclasses and multiple
6250 inheritance into account.
6252 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6256 Fri May 4 12:12:55 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6258 * breakpoint.c (watch_command, bpstat_stop_status): Deal with
6259 exp_valid_block field correctly.
6261 * infrun.c (wait_for_inferior): When checking "don't even think
6262 about breakpoints" if stop_signal == SIGTRAP && trap_expected,
6263 also check step_resume_breakpoint.
6264 Insert breakpoints and continue (not step) if
6265 step_resume_break_address != NULL, even if another_trap.
6266 If trap_expected and we enter sigtramp, then set up a
6268 If trap_expected is set when we hit the step_resume_break,
6270 When calling resume and trap_expected says tell resume to step
6271 (2 places), also check step_resume_break_address.
6273 * infrun.c (wait_for_inferior): Don't set
6274 prev_{pc,sp,func_{start,name}} before calling wait ().
6275 Do set them after exiting loop.

6279 Thu May 3 00:15:11 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6281 * infrun.c (wait_for_inferior, after check for trap_expected > 1):
6282 Restore old code which distinguishes between trap_expected and
6283 running_in_shell, just make the latter take any non-TRAP signal,
6286 * values.c (allocate_value): Zero VALUE_OPTIMIZED_OUT flag.
6288 * Makefile.dist (pinsn.o): Use PINSN_CC to compile.
6289 xconfig/3b1 (CC,PINSN_CC): Define.

6312 * value.h: Add optimized_out field and change lazy field to
6313 char. Add macro VALUE_OPTIMIZED_OUT.
6315 * i386-pinsn.c: Change from Eirik Fuller to write to stream directly
6316 instead of stuffing things in buffers (oappend, etc).
6318 * breakpoint.c (bpstat_do_actions): If *BSP is set to NULL by
6319 execute_command, exit both loops.
6321 * Makefile.dist: Don't set TARGET_ARCH. Add .c.o rule.

6328 m68k-xdep.c, coredep.c: Wrap in #if !defined (RDB).
6330 * valops.c (value_struct_elt), values.c (value_static_field):

6348 findvar.c (get_saved_register): New function.
6349 findvar.c: Rewrite code which called find_saved_register to
6350 call get_saved_register instead.
6352 Sun Apr 22 14:47:51 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6354 * valprint.c (val_print): Change error message printed when
6355 the type has TYPE_FLAG_STUB set.

6389 (enter_linenos): Use it.
6390 * blockframe.c: Add INIT_FRAME_PC hook and use it in
6391 get_prev_frame_info.
6392 m-m88k.h: Use INIT_{FRAME_PC,EXTRA_FRAME_INFO} to do tdesc stuff.
6393 Use dummy versions of FRAME_CHAIN_*.
