1 Wed Nov 13 19:51:11 1991 Steve Chamberlain (sac at cygnus.com)
3 * Makefile.in, xconfig/delta88 made it install a sysV manual page;
4 gdb.z into the right place.
6 Wed Nov 13 16:45:13 1991 John Gilmore (gnu at cygnus.com)
8 Motorola 88000 port without tears, I mean without tdescs.
10 * m88k-tdep.c: Blow away all tdesc stuff.
11 Provide functions for all the frame-related macros in
12 tm-delta88.h. Adopt i960-style EXTRA_FRAME_INFO.
13 (examine_prologue, frame_find_saved_regs, skip_prologue): borrow
14 from i960-tdep.c and adapt to the function prologues on the 88k.
15 (read_next_frame_reg): Borrow from mips-tdep.c.
16 FIXME: frame_locals_address should go away.
18 * tm-delta88.h: Dump all the tdesc stuff.
19 Macros for all frame-related stuff call fns of same name.
20 Remove duplicated definitions. FP_REGNUM becomes same as
23 * xm-88k.h: Eliminate lots of library dependencies, now handled
24 in libiberty. Eliminate KDB nonsupport.
26 * doc/gdbint.texinfo: Add rudiments on frames. FIXME, add more.
29 * stack.c (frame_info): Mark frameless functions.
30 Print locals address (FIXME, remove if same).
31 * blockframe.c: Comment changes, FIXME after.
32 * coffread.c: Even without TDESC, need to zap "@" symbols.
33 Don't register for wierd format names; change the names in BFD.
35 * alloca.c, language.c, tdesc.c: Lint.
36 * tdesc.c, tdesc-lib: FIXME: remove these.
38 Tue Nov 12 19:30:22 1991 John Gilmore (gnu at cygnus.com)

47 Allow setting breakpoints on C++ destructors.
48 * valops.c (destructor_name_p): Don't check TYPE_HAS_DESTRUCTOR,
49 since it lies. Rely on callers to catch missing destructors.
50 * symtab.c (decode_line_1): For example (see above), here.
51 * buildsym.c, symtab.h: Remove TYPE_FLAGS_HAS{CON,DE}STRUCTOR
52 flags since they are no longer used.
54 Fixes to support C++ methods with functional parameters.
55 * c-exp.y (func_mod rule): Allow (and ignore) list of parameter
56 types in a function type.
57 * eval.c (parse_and_eval_type), value.h: New function,
58 parse_and_eval_type, is based on old code from check_stub_method.
59 But don't actually evaluate the cast, since that calls
60 value_cast(), whcih may fail. Just extract the type
61 from the parsed expression.
62 * values.c (check_stub_method): While looping through the
63 arguments, adjust depth *after* parameter has been handled.
64 Replace call and setup of parse_and_eval with new function
67 Tue Nov 12 09:40:07 1991 Fred Fish (fnf at cygnus.com)
69 * utils.c, rem-multi.shar: Remove fixed arg count version of

74 m88k-xdep.c, main.c, printcmd.c, pyr-xdep.c, source.c,
75 sun386-xdep.c, symm-xdep.c, umax-xdep.c, values.c, xcoffread.c:
76 Change all instances of use of fixed args concat() to variable
77 args concat() now located in libiberty.
79 Tue Nov 12 07:23:46 1991 John Gilmore (gnu at cygnus.com)
81 * Makefile.in: Add xcoffread.c, xcoffexec.c.
82 * xcoffread.c: New file for handling AIX mangled-coff files.
83 * xconfig/rs6000, tconfig/rs6000: New files.
84 * buildsym.c: Add hooks for xcoffread.c.
85 * rs6000-pinsn.c, rs6000-tdep.c, rs6000-xdep.c, tm-rs6000.h,
86 xm-rs6000.h, rs6k-opcode.def, rs6k-opcode.h: New files.

92 (and possibly arguments to) the program that generated a core
95 * elfread.c: Remove the register_addr() stub now that it is no
98 * procfs.c: Move misplaced #endif for ATTACH_DETACH. Add new
99 fetch_core_registers() function for core file support.
101 Sat Nov 9 13:37:57 1991 Fred Fish (fnf at cygnus.com)
103 * dwarfread.c (dwarf_psymtab_to_symtab): Remove leftover call
104 to do_cleanups() which resulted from a previous change.
106 * elfread.c: Re-enable compilation of register_addr() stub
107 whenever it is not supplied by coredep.c
109 Sat Nov 9 00:40:32 1991 John Gilmore (gnu at cygnus.com)
111 Add tracking of object files (that contain symbols) to gdb.
112 This includes a "struct objfile" that owns symtabs and psymtabs
113 that were read in from that binary file.
115 * symfile.h: Add struct objfile. Add pointer to the objfile
116 into the struct sym_fns.
117 Replace global `symfile' and `symfile_mtime' with
118 `symfile_objfile'. Add global object_files chain.
120 * symfile.c: Move param.h above symtab.h.
121 (sort_misc_function_vector): Add.
122 (syms_from_objfile): Was syms_from_bfd.
123 (symfile_open): Now returns objfile.
124 (allocate_objfile): New.
125 (free_objfile): New, replacing free_all_.*symtabs.
126 (symfile_init): Takes objfile arg, puts it in sym_fns result.

128 (allocate_symtab): Takes objfile as new parameter, chains them.
129 Handle INIT_EXTRA_SYMTAB_INFO.

132 * dbxread.c: Make more errors into complaints.
133 (push_subfile, pop_subfile): Move to buildsym.c.
134 (dbx_symfile_read, dbx_symfile_init, fill_symbuf, read_dbx_symtab,
135 start_psymtab, psymtab_to_symtab_1, read_ofile_symtab,
136 dbx_psymtab_to_symtab, ): Use bfd ops, don't use file descriptor.
137 Pass objfile. Change callers.
138 (fill_symbuf, SWAP_SYMBOL): Take bfd as arg.
139 (read_dbx_symtab): Just wipe out new symbols, not all, on error.
140 (end_psymtab): Blow away psymtab if empty.

146 (dbx_lookup_type): Handle null typevector.
147 (dbx_alloc_type): Check file number, not sym number, for -1.
148 (find_symbol_in_list): Add for xcoffread.
149 (start_symtab): Default typevector is empty. Keep reusing same
151 (end_symtab): Take objfile argument and pass it to
152 allocate_symtab. Don't make a symtab if no blocks or symbols.
153 Handle empty typevector.
154 (push_context): New function for context stack nesting.
155 (read_type): Mark FIXME where we need to reintroduce type smashing.
157 * buildsym.h (pop_context): Macro, paired with push_context.
158 (subfile_stack): Move here from dbxread.c.
160 * coffread.c (end_symtab, read_coff_symtab): Take and use objfile arg.
161 (read_coff_symtab): Cleanup by freeing objfile, not all symtabs.

169 and use objfile argument.
170 (psymtab_to_symtab_1, read_ofile_symtab): Don't take or use file
171 descriptor. Use BFD internal functions instead.
172 (end_symtab): Call global allocate_symtab.
174 * elfread.c, target.c: Minor changes to accommodate objfiles.
175 * symtab.h: partial_symbol_table has no symfile_name member now.

177 (struct symtab): Add objfile * and objfile_chain * of symtabs.
178 (struct partial_symtab): Add objfile * and objfile_chain * of
179 psymtabs. Remove symfile_name.

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

506 * infrun.c (wait_for_inferior): fix stepi/nexti that was broken
507 by my last edit to this routine.
509 Mon Oct 21 14:27:43 1991 John Gilmore (gnu at cygnus.com)
511 * tm-sun3.h (FIX_CALL_DUMMY): problem with cross debugging.
512 FIX_CALL_DUMMY does unaligned accesses and/or forgets to byte swap
513 the values before putting them into the dummy code. (From Peter
516 Mon Oct 21 10:04:39 1991 Steve Chamberlain (steve at rtl.cygnus.com)

529 it find the registers in the core-file header.
530 * coredep.c (fetch_core_registers): Take new argument, use it,
531 and pass it to register_addr to locate the block of registers.
532 * xm-mips.h: Update KERNEL_U_ADDR for new scheme. Cleanup a bit.
534 * dbxread.c (read_dbx_symtab, process_one_symbol): Handle
535 Sequent N_FN_SEQ like everybody else's N_FN.
537 * main.c: Circumvent SCO cc bug with #if !!defined(USG).
538 * tm-i386v.h: #endif guck.
539 * xconfig/i386*: Remove -Dgetpagesize()=4096 kludge.
540 * xconfig/i386sco: Add HAVE_STRSTR to avoid ANSI bdeath.
541 * xconfig/tahoe: Add REGEX, which seems to be missing.
543 * coredep.c: Add <sys/types.h> for SCOnix.
544 * dbxread.c (read_dbx_symntab): Avoid coredump on malformed file.
545 * printcmd.c (print_formatted): Flush output before disassembly.
547 Tue Oct 15 20:12:32 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
549 * doc/refcard.tex (sec "Working Files"): consistent metavars and
550 other improvements, due to comments by François Pinard
551 (pinard@iro.umontreal.ca)
553 * doc/gdb.texinfo (appendix "Installing GDB"): changes in
554 configure, and improvenets related to Pinard's refcard comments
556 Tue Oct 15 08:45:12 1991 John Gilmore (gnu at cygnus.com)

573 * i387-tdep.c (double_to_i387): Fix typo for double_to_ieee_extended.
574 * utils.c (_initialize_utils): If !ISATTY, don't paginate.
575 * configure.in, tconfig/decstation, xconfig/decstation: Rename
576 dec3100 to decstation.
578 Mon Oct 14 13:37:50 1991 Roland H. Pesch (pesch at cygnus.com)
580 * doc/gdb.texinfo: Catch up to changes recorded here in ChangeLog
581 (nodes Continuing and Stepping; Memory; Targets) clarifications
584 Fri Oct 11 23:27:06 1991 John Gilmore (gnu at cygnus.com)
586 * tm-{irix3,mips,nindy960,pn,symmetry,vx960}.h: Move

606 Wed Oct 9 17:03:34 1991 John Gilmore (gnu at cygnus.com)
608 * mipsread.c, coffread.c: initialise TYPE_VPTR_FIELDNO to -1.
609 This avoids coredumps under `set print object on' in value_headof
610 (called erroneously by value_from_vtable_info) for `p &struct'
611 or `p *struct'. From Peter Schauer.
613 Mon Oct 7 00:06:52 1991 John Gilmore (gnu at cygnus.com)
615 * Makefile.in: Roll version to 4.1.2.
616 * dbxread.c: Use aout64.h, not a.out.gnu.h. Get external symbol entry
617 size from BFD (but, FIXME, we don't yet read external nlists's and
618 convert them to internal nlists's before handling them -- we still
619 assume they have the same size and alignment.) Use SET_NAMESTRING
621 * exec.c (exec_file_command): Move dead coff-encapsulation code
623 * m88k-tdep.c, m88k-xdep.c: Remove encap test and #inc <a.out.h>.

630 Fri Oct 4 17:04:31 1991 Per Bothner (bothner at cygnus.com)
632 More patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
633 * mips-xdep.c (store_inferior_registers): Don't try to
634 write the (pseudo) FP.
635 * mipsread.c (parse_partial_symbols): Improved algorithm for
636 setting pst->texthigh.
638 Fri Oct 4 16:47:32 1991 Roland H. Pesch (pesch at cygnus.com)
640 * doc/Makefile: make TEXINPUTS include . everywhere
642 Fri Oct 4 00:35:56 1991 John Gilmore (gnu at cygnus.com)
644 * coffread.c, dbxread.c, symfile.c, symmisc.c, symtab.h: Remove
645 vestiges of typevectors, which were for symsegs and are no longer
646 used. (From a question by Eliot Dresselhaus
647 <dresselh@RFT30.nas.nasa.gov>).
649 Thu Oct 3 09:33:26 1991 John Gilmore (gnu at cygnus.com)
651 * dbxread.c, coffread.c: static-ize functions that were
652 gratuitiously external. (From Fred Fish.)
654 * c-exp.y: sym->class to SYMBOL_CLASS (sym).
656 * dbxread.c (dbx_lookup_type): Keep doubling size of typevector
657 until it is large enough.
659 * dbxread.c (read_type): Handle error case slightly better.
660 Make complaint message not C++-specific.
662 Wed Oct 2 17:21:07 1991 Stu Grossman (grossman at cygnus.com)
664 * infrun.c (wait_for_inferior): Fix step/next so that you only
665 stop at the beginning of a new line. This fixes various problems
666 with for loops, nested if-else's and switch statements.
668 Tue Oct 1 06:33:55 1991 John Gilmore (gnu at cygnus.com)
670 * symtab.c (lookup_symtab_1, lookup_symbol): "fatal" errors
671 between symtabs and psymtabs become ordinary error()s.
673 * dbxread.c (read_dbx_symtab): Relocate end_of_text_addr
674 properly, making "end pc" correct in shared lib psymtabs.
675 (From Guy Harris <guy@auspex.com>.)
677 Mon Sep 30 13:15:31 1991 John Gilmore (gnu at cygnus.com)
679 * dbxread.c: Enable, but soften, const_vol_complaint.
680 (read_dbx_symtab): N_STSYM and N_LCSYM define static vars.
681 Ditto Gould N_NBSTS and N_NBLCS. Also, all types in the psymtab
682 should be file-scope, not global.
683 (read_struct_type): Remove ancient multiple-inheritance warning.
684 (read_range_type): Check base type, complain & patch if undefined.
685 * stack.c (frame_info): Demangle the function name in `info stack'.
688 Sat Sep 28 10:02:33 1991 John Gilmore (gnu at cygnus.com)
690 * eval.c (evaluate_subexp_for_address): Don't use
691 TYPE_POINTER_TYPE directly (it might be zero if this type has
692 never had a pointer created before); use lookup_pointer_type.
693 * symtab.c (lookup_method_type): Arguments were swapped in all
694 callers, so fix it here. I'm amazed this worked at all!
696 Fri Sep 27 18:09:31 1991 John Gilmore (gnu at cygnus.com)
698 * c-exp.y, m2-exp.y: Define more yysymbols that happen to be
699 "bss" rather than "data" symbols, but which still conflict.
702 * coffread.c (coff_symfile_read): Use xmalloc, not malloc.
703 * core.c (core_files_info): Shorten output.
704 * exec.c (exec_files_info): Ditto.
705 (build_section_table): Ignore zero-length sections.
706 * language.c, printcmd.c: Lint.
707 * language.h (get_frame_language): Declare.

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

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

839 symtab is not read in.
840 * mips-tdep.c: Remove some unneeded #includes.
841 * xconfig/dec3100: Add HAVE_STRSTR.
843 Thu Sep 19 15:14:23 1991 John Gilmore (gnu at cygnus.com)

952 Tue Sep 17 08:37:41 1991 John Gilmore (gnu at cygint.cygnus.com)
954 Add Andrew Beers' changes for Modula-2 support. His ChangeLog
955 entries are enclosed herein. Not all of these changes
956 have been merged into the master GDB sources -- check the
957 ChangeLog above here for the merge log.
959 Mon Jun 3 17:05:45 EDT 1991
961 m2-exp.y Created. Tested outside of GDB for a few days. Proper
962 operators were added, C specific operators and tokens
963 removed. yylex() revamped to some extent. Still things
964 missing from the grammar, such as sets.
965 Tested for two weeks in GDB v3.5.
967 Tue Jun 11 17:23:48 EDT 1991
969 m2-exp.y Added boolean constants TRUE and FALSE to the grammar
970 so they are built-in. Sort of a hack.
972 Fri Jun 14 12:53:51 EDT 1991
974 m2-exp.y Added range checking for numeric constants. Any numeric
975 constant is assumed to be of builtin type INTEGER unless:
976 (1) it is octal or hexadecimal, in which case it is a
977 CARDINAL; (2) it is too big to fit into an INTEGER, in
978 which case it is a CARDINAL.
979 eval.c Added simple range checking for +, -, and * on integers.
980 Doesn't work very well for *, since 6 * 1,000,000,000 =
981 1,705,032,704, which fails the simple test of result >=
982 first_operand, no matter in what order the operands are.
984 Tue Jun 18 14:11:30 EDT 1991
986 Broke the parser into parts, one containing the C grammar and the other
987 containing code to be shared by all of the grammars.
989 The following files no longer exist:
994 The following files were added:
996 c-exp.y (The C grammar)
997 m2-exp.y (The Modula-2 grammar)
998 parser-code.c (Code that is shared by the above grammar)
1002 Makefile.dist Changed to reflect the above dependencies. NOTE: It is
1003 now necessary to use the Bison compiler compiler, since it
1004 will generate function/variable prefixes other than yy.
1006 Tue Jun 18 16:47:49 EDT 1991
1008 symtab.[ch] Added the external variable working_lang, than holds the
1009 value of the current working language.
1010 Added the ennumerated type language_mode, with the values
1011 language_auto and language_manual, the former meaning that
1012 GDB sets working_lang as needed, and the latter meaning
1013 that the value of working_lang is totally under user
1015 symtab.[ch] Added the Modula-2 pervasive types INTEGER, CARDINAL,
1016 REAL, BOOLEAN and CHAR. Also added the type codes
1017 TYPE_CODE_BOOL and TYPE_CODE_CHAR.
1018 utils.c Added set_language_command and show_language_command to
1019 implement the GDB support commands "set language" and
1021 expression.h A number of identifiers were added to the type exp_opcode
1022 to facilitate Modula-2 builtin functions, integer
1023 division, and array indexing.
1025 Wed Jun 19 13:25:58 EDT 1991
1027 language.h Added the macro STRICT_TYPE, which evaluates to non-zero
1028 if the language specified by working_lang requires the use
1029 of strict typing of expressions. Eventually, even this
1030 will be able to be changed by the user.
1031 Added the macro RANGE_CHECK, which evaluates to non-zero
1032 if the language specified by working_lang requires the
1033 checking of a value against the domain of its type.
1034 Eventually, even this will be able to be changed by the
1036 language.[ch] Predicates involving types (simple_type, ordered_type,
1037 same_type, integral_type, numeric_type, character_type,
1038 boolean_type, float_type) are added. These predicates are
1039 based on the current value of working_lang, and are handy
1042 Wed Jun 19 15:39:34 EDT 1991
1044 eval.c Added the function type_array_rank which computes the rank
1046 valarith.c Added the funtion value_bool, which when given a integer
1047 value.h value (ie. struct value *) as an argument, it returns a
1048 boolean value (ie. struct value *) true if that integer
1049 is non-zero, and a boolean value false otherwise.
1050 valprint.c Added cases for TYPE_CODE_BOOL, so Modula-2 BOOLEAN values
1051 will print out properly.
1053 Wed Jun 19 16:36:34 EDT 1991
1055 valops.c Added the function value_capitalize, which returns it
1056 value.h argument capitalized if its argument is a lowercase
1057 letter, or the argument unchanged if its argument is not a
1059 valarith.c Added the function range_check_p, which returns non-zero
1060 value.h if its value argument is between the integral bounds upper
1062 Added the function range_check_enum_p, which makes sure
1063 that its value argument is a valid member of the domain of
1065 Added the function range_check_range_p, which makes sure
1066 its value argument lies between the upper and lower bounds
1067 of its type argument, which must be a ranged type.
1068 Added the function check_array_index, which range and type
1069 checks an index of an array.
1070 Added the function value_multi_subscript, which computes
1071 array[idx1,idx2...idxN], given a value array and an array
1072 of values representing indicies.
1073 values.c Changed value_from_long to work with TYPE_CODE_CHAR and
1074 unpack_long to work with TYPE_CODE_BOOL and
1077 Wed Jun 19 18:04:08 EDT 1991
1079 symtab.c Stored pervasive types in a structure and make
1080 lookup_pervasive_type() a lookup function that was based
1081 on working_lang. If lookup_pervasive_type() returned
1082 non-zero, then that value was returned (a fix, since
1083 before it simply wouldn't return the pervasive type.)
1084 language.h Added the macro CAST_IS_CONVERSION, which evaluates to
1085 non-zero if the language specified by working_lang means
1086 "conversion" when it says "cast".
1087 valops.c Added the function value_real_cast(), which performs a
1088 value.h *cast*, not a *conversion*, which is what value_cast()
1089 does when it can. In particular,
1090 value_cast(<float_type>,4) = 4.0, while
1091 value_real_cast(<float_type>,4) = some mess.
1092 eval.c Modula-2 builtin functions implemented: ABS, CAP, CHR,
1093 parser-code.c FLOAT, HIGH, MAX, MIN, ODD, ORD, TRUNC, and VAL.
1094 expression.h Added macros MAX_OF_TYPE and MIN_OF_TYPE to work with MAX
1095 and MIN on integral types. *NOTE*: These are currently
1096 hardcoded to work only if there are 8 bits per storage
1098 eval.c Made logical functions call value_bool to return a
1099 properly typed boolean value, based on working_lang.
1101 Thu Jun 20 11:55:27 EDT 1991
1103 valprint.c Types now print out in a Modula-2 fashion. This works for
1104 the cases when the type is printed out step-by-step, that
1105 is, it doesn't work when the name of a structured type
1106 (which includes the keyword "struct", etc.) is simply
1108 FIXME: Perhaps this is bad. Parts of it seem to kludgey,
1109 since type specifications in C and Modula-2 are very
1110 different. The C printing of a type is very recursive,
1111 whereas in Modula-2 it is generally very simple. C has
1112 type prefixes and suffixes, which have no real analogue in
1113 Modula-2. Maybe type_print() should call a language
1114 specific type printer. This is also advantageous if we
1115 compile GDB to exclude some of the languages. We'll just
1116 leave those functions out.
1118 Thu Jun 20 16:57:10 EDT 1991
1120 dbxread.c When reading the complete symbol table in (via
1121 psymtab_to_symtab()), the number and types of function
1122 arguments are added to a function type. define_symbol()
1123 calls add_param_to_type() to accomplish this.
1124 Assumption: when we come across a function definition
1125 (N_FUN symbol with an 'f' or 'F' in the name), its
1126 arguments will appear before another function definition.
1127 When a function is found, a pointer to its type is placed
1128 in the global in_function_type. Changes that
1129 add_param_to_type() makes are to this global.
1130 valprint.c The type of a function now includes (for Modula-2) the
1131 types of its parameters.
1132 eval.c Type checking and a check for the proper number of
1133 arguments is now done for function calls. Not sure of the
1134 impact this has on C++ member function yet.
1136 Thu Jun 20 19:58:48 EDT 1991
1138 valprint.c Rewrote the type printer. Broke it into two language
1139 specific parts, adding the functions type_print_m2() and
1141 An unfortunate consequence is this: if you debugging a C
1142 program in Modula-2 mode (why?), info types does not work
1143 well with regular expressions, since the types are printed
1144 out in Modula-2 terminology, but stored in C terminology.
1145 language.[ch] Added the functions new_type_last(), type_keyword(), and
1146 type_sep() to aid in the printing of typedefs.
1147 symtab.c Made the printing of typedefs as language independent as
1148 possible through calls to new_type_last(), type_keyword(),
1151 Fri Jun 21 11:50:26 EDT 1991
1153 dbxread.c Check all incoming ennumerated types. If it looks like
1154 Modula-2's BOOLEAN type, then change the type_code of the
1155 type to TYPE_CODE_BOOL so we can process it as a boolean
1157 valprint.c Replaced some of the 0x%x with calls to sprintf and
1158 hexformat() in val_print().
1159 language.[ch] Added the function hex_to_string(), which converts its
1160 integral argument to a hexadecimal number (format is
1161 language based) and returns the result as a string.
1163 Mon Jun 24 12:25:07 EDT 1991
1165 valprint.c Some functions call type_print_1() directly, instead of
1166 value.h using type_print(), so they can specify where (column) to
1167 print things. Since type_print() takes care of language
1168 dependence, that needs to be called first. Added a
1169 parameter depth to type_print() (so it is now like
1170 type_print_1). Changed type_print to type_print_at, and
1171 made type_print a macro that passes a depth argument of
1173 symmisc.c Changed all calls to type_print_1 to calls to
1175 Makefile.dist Made it possible to build GDB for a specific set of
1176 depend languages. Do this by passing a definition for the macro
1177 LANGS to make. LANGS should be a string containing a
1178 space-separated list of language names (ie. LANGS="c m2").
1179 The default is to build all languages. Note that grammar
1180 files must follow the naming convention of <lang>-exp.y.
1181 gdb.lang This holds the current value of the LANGS macro. It is
1182 examined every time make is called, and is updated if
1184 eval.c Added #ifdef _LANG_<lang> to these files.
1185 expread.c Still need to add them to dbxread.c and coffread.c.
1193 Mon Jun 24 16:33:11 EDT 1991
1195 language.[ch] Added the functions hexformat_pre() and
1196 hex_to_string_pre(), which take a prefix argument to
1197 include in the format string. Thus, hexformat_pre("08") will
1198 return "0x08x" (if the working language is language_c).
1199 Made hexformat() and hex_to_string() calls to the above
1200 with "" as the prefix argument.
1202 am29k-pinsn.c, arm-pinsn.c, breakpoint.c, convex-tdep.c, exec.c, core.c,
1203 dbxread.c, i386-pinsn.c, i386-stub.c, i386-xdep.c, i960-pinsn.c,
1204 infcmd.c, inflow.c, m68k-pinsn.c, m68k-stub.c, m88k-pinsn.c,
1205 mips-pinsn.c, mips-tdep.c, ns32k-pinsn.c, printcmd.c, pyr-pinsn.c,
1206 pyr-tdep.c, pyr-xdep.c, remote-vx.c, remote.c, solib.c, source.c,
1207 stack.c, sun386-xdep.c, symfile.c, symm-xdep.c, symmisc.c, tahoe-pinsn.c,
1208 valprint.c, vax-pinsn.c
1210 Changed all occurences of 0x%[0-9]*l*x in printf format strings to
1211 calls to hexformat() and hex_to_string(). Format strings without
1212 the leading "0x" were ignored.
1214 depend Updated to take the above into account.
1217 Tue Jun 25 15:27:18 EDT 1991
1219 symtab.h Added the types range_mode_t, range_check_t, type_mode_t,
1220 and type_check_t to keep track of the current state of
1221 range and type checking.
1222 main.c Added the variables range_mode, range_check, type_mode,
1223 and type_check to record the current state of range and
1224 type checking. Added initialization code to main().
1225 language.h Changed the macros STRICT_TYPE and RANGE_CHECK to examine
1226 the above variables.
1229 Tue Jun 25 17:57:08 EDT 1991
1231 dbxread.c process_one_symbol() updates the variable (enum language)
1232 source_lang based on the extension of the filename
1233 contained in the N_SO sybmol that started this symtab.
1234 When end_symtab() is called, the value of source_lang is
1235 put into the language field.
1236 stack.c select_frame() sets working_lang (and possibly type_check
1237 and range_check) to the language field of the symtab
1238 associated with the frame that is selected if working_mode
1239 is language_auto. If working_mode is language_manual, a
1240 warning is printed and working_lang is not set.
1241 language.c Added the function set_type_range(), which sets the value of
1242 type_check and range_check (if their modes call for
1243 automatic setting) based on the current value of
1244 working_lang. A non-zero argument will cause the current
1245 settings to be output.
1248 Wed Jun 26 14:51:40 EDT 1991
1250 eval.c Added range checks on assignment.
1251 m2-exp.y Added the grammar for sets to the language. Currently,
1252 these do not do anything except print an error message.
1254 Wed Jun 26 17:01:04 EDT 1991
1256 m2-exp.y Added the ability for parse_number() to parse negative
1257 numbers. A global flag is set upon encountering a unary
1258 minus. This was done to make, for example, 1 parse as a
1259 CARDINAL, and not as an integer, per Wirth's examples in
1260 Programming in Modula-2 ed.4.
1261 valprint.c Added support for "set radix 2" by then setting
1262 output_format to 't'.
1263 eval.c Implemented range checking on subrange types. Added calls
1264 to range_check_range_p for BINOP_ASSIGN and BINOP_VAL.
1265 Implemented MIN and MAX for ennumerated types. The
1266 minimum value of an ennumerated type is defined by Wirth
1267 as the first identifier, and the maximum as the last.
1268 m2-exp.y Made octal numbers ending with "B" be characters and those
1269 ending with "C" be numbers, per Wirth's book. (p. 34)
1271 Thu Jun 27 14:11:52 EDT 1991
1273 stack.c select_frame() now only sets working_lang, it does not
1274 notify the user. If working_mode is language_manual, then
1275 a warning is issued once.
1276 main.c At the end of each call to execute_command(), working_lang
1277 is checked against the local static (enum language)
1278 current. If they differ and working_mode is
1279 language_auto, the new settings of language, type and
1280 range checking are printed out.
1281 stack.c Modified frame_info() to include the language of the
1282 current frame in the output of "info frame".
1283 language.[ch] Added the function language_str() which returns the name
1284 of the current language.
1286 Fri Jun 28 15:33:14 EDT 1991
1288 m2-exp.y Added the built-in procedures INC, INCL, DEC, and DECL to
1289 the language. INCL and DECL currently cause an error,
1290 since sets are not implemented yet. INC and DEC are
1291 implemented as PREINCREMENT/PREDECREMENT with one
1292 argument, and as ASSIGN_MODIFY with two arguments.
1293 eval.c Added type checking to the above cases.
1294 value.h Added not_lval_constant to the lval_type ennumerated type.
1295 not_lval_constant means that the value is a constant
1296 value; that is 3 or 'a' or TRUE, not as in a constant
1297 identifier. This is used to help coerce numbers such as 3
1298 to either signed or unsigned numbers.
1299 valops.c Added the function value_coerce_constants() which coerces
1300 constant integers as following: if one is a constant and
1301 the other is not, the constant's type is set to the type
1302 of the other argument. If both are constants and one is
1303 signed, the other is converted to a signed constant.
1305 Sat Jun 29 17:26:29 EDT 1991
1307 valarith.c Added a better range checker. It now checks range
1308 (successfully) on integral operations [+-] (signed and
1309 unsigned) for any C sized type. Still does not work well
1310 for multiplication.)
1311 int_in_size() returns an integer that is coerced to fit into
1312 specified number of bytes.
1314 Mon Jul 1 13:04:14 EDT 1991
1316 language.[ch] Added the function binop_result_type(), which returns the
1317 builtin (struct type *) type that would be the result of a
1318 binop on the two values V1 and V2.
1320 Wed Jul 3 19:22:53 EDT 1991
1322 source.c Extended source_info() to include the source language in
1323 the output from "info source".
1325 Fri Jul 5 13:48:52 EDT 1991
1327 utils.c Moved the support functions for the GDB set/show commands
1328 dealing with language into language.c.
1329 language.c Added the function language_info(), which displays info
1330 about the current working language, type and range check
1331 settings. Called via the GDB command "info language".
1332 Added an initialization routine _initialize_language(),
1333 that sets defaults for the language, type and range
1334 variables and sets up the new GDB commands.
1335 main.c Language setup moved to language.c.
1338 Mon Jul 8 10:10:22 EDT 1991
1340 valarith.c Debugged the range checker for arithmetic. Still does not
1341 work for multiplication very well.
1343 Mon Jul 8 12:40:37 EDT 1991
1345 language.[ch] Added the function value_true() which returns non-zero if
1346 its argument represents a boolean true value.
1347 breakpoint.c Changed breakpoint_cond_eval() to call value_true() to
1348 check the truth of an expression.
1350 Thu Jul 11 12:51:34 EDT 1991
1352 language.[ch] Added the predicate structured_type(), which returns
1353 non-zero if the argument is a structured type.
1354 Added the predicate pointer_type(), which returns non-zero
1355 if the argument is a pointer type.
1356 eval.c Added the ability to do addition and substraction on
1357 pointers and integers. This case simply bypasses the
1360 Thu Jul 11 14:41:42 EDT 1991
1363 Added the symbol N_DEFD (0x4a) which is a definition
1364 module dependency that is used by the GNU Modula-2
1365 compiler and the linker. It is not important to GDB,
1366 except that [dbx|coff|mips]read.c should ignore these
1369 Fri Jul 12 16:07:00 EDT 1991
1371 valprint.c Changed the TYPE_LENGTH(type) >= 0 to TYPE_LENGTH(type) >
1372 0 in val_print(). Also added statements to the else part
1373 to coerce type (argument to val_print) to a pointer type
1374 if it is an "array of unspecified length".
1375 valops.c Added the function value_m2_string(), which returns a
1376 (value) value which is a constant string, whose type is
1377 (ARRAY [0..n] OF CHAR). The length field of the type
1378 structure is set to zero, so it will be interpreted as an
1379 "array of unspecified length".
1380 stack.c Moved the language/frame mismatch check to
1381 main.c:execute_command().
1382 main.c The working language is recorded each time
1383 execute_command() is executed. If working lang has
1384 changed during its execution, then the new
1385 language/type/range info is printed out for the user. If
1386 the working language does not match the language of the
1387 frame, a warning is issued.
1389 Sat Jul 13 16:16:39 EDT 1991
1391 eval.c Moved all the type-checking stuff for operators to
1392 language.[ch] language.c. This is so we can keep language-specific
1393 stuff (like for what type operators are defined) in
1395 language.[ch] Added the function binop_type_check(), which checks to see
1396 if its two (value) arguments are type-compatible with its
1397 opcode argument. The opcode should represent an operation
1398 involving an operator. Also added the macro function
1399 unop_type_check, which calls binop_type_check with a
1400 NULL second argument.
1401 expprint.c Added Modula-2 operators to the op_print_tab, so info
1402 expression.h break works correctly. Also added "op_string", which
1403 returns the string corresponding to the (enum exp_opcode)
1404 opcode that is its argument.
1407 Sat Jul 13 18:26:18 EDT 1991
1409 coffread.c Added code to record the type of function arguments with
1410 each paricular function. Code is very similar to that
1412 dbxread.c Moved add_param_to_type() to symtab.c
1413 symtab.[ch] Added function add_param_to_type() from dbxread.c
1415 *** NOTE: The above additions have not been tested.
1417 Mon Jul 15 12:50:47 EDT 1991
1419 langauge.[ch] Added the functions type_error and range_error, which work
1420 like error() except if the type/range mode is set to
1421 *_mode_warn, then they do not do a return_to_top_level(),
1422 but merely print a warning.
1423 Also changed [set|show]_[type|range]_command() to support
1424 the new "warn" feature.
1426 Thu Jul 18 17:50:54 EDT 1991
1428 mipsread.c Added code to record the type of function arguments with
1429 each particular function. Code is very similar to that
1432 *** NOTE: The above additions have not been tested.
1434 Fri Jul 19 11:19:10 EDT 1991
1436 defs.h Added macros MAX_OF_SIZE, MIN_OF_SIZE, UMAX_OF_SIZE, and
1437 UMIN_OF_SIZE, which when given a size of a numeric type,
1438 return the maximum and minimum value it can hold. UMAX...
1439 and UMIN... return the result for unsigned types.
1440 symtab.h Added the macros MAX_OF_TYPE and MIN_OF_TYPE to operate on
1441 struct types. They call above macros.
1442 dbxread.c Renamed the MAX and MIN_OF_TYPE macros to ..._OF_CTYPE to
1443 avoid a name conlict with the above.
1444 c-exp.y Added range checking on numeric constants in
1445 parse_number() for completeness.
1446 valarith.c Made binop_user_defined_p() and unop_user_defined_p()
1447 return 0 if working_lang is not language_c.
1449 Thu Aug 8 14:17:22 EDT 1991
1453 breakpoint.c Documentation strings of some commands changed to
1454 eliminate the references to the C language where
1457 Tue Aug 13 15:48:03 EDT 1991
1459 m2-exp.y Added qualified identifiers to the grammar. The semantics
1460 are slightly different from those of the GDB operator ::
1462 m2-exp.y Added a rule to each grammar of the form: start ::= exp |
1463 type_exp, where type_exp is any valid type expression.
1465 eval.c Added the opcode OP_TYPE, and an error case in eval.c.
1466 printcmd.c Modified ptype_command() so it actually parses the input
1467 (necessary for type expressions with scope qualifiers).
1468 Added the function ptype_eval() which expects an
1469 expression composed of one OP_TYPE element.
1470 *.[ch] Replaced all occurences of parse_c_expression with
1472 *.[ch] Replaced all occurences of parse_c_1 with parse_exp_1
1474 [End of ChangeLog entries from Andrew Beers for Modula-2 support.]
1476 Mon Sep 16 17:19:46 1991 John Gilmore (gnu at cygnus.com)
1478 Small fixes from Peter Schauer:
1480 * infrun.c (child_attach): Lint.
1481 * solib.c (find_solib): Handle shared libs version 2.
1483 Small fixes from David Wood:
1485 * xm-ultra3.h (SYS_SIGLIST_MISSING): Typo.
1489 * remote-vx.c: Move <stdio.h> to top, for FILE. Fix from
1490 John S <basrai%kanga.dnet@c3po.sm-alc.af.mil>.
1492 * utils.c (wrap_here): Avoid wrap action of fputs_filtered if
1493 chars_per_line is at maximum (user typed `set width 0'). Fix
1494 from Andreas Schwab <schwab@ls5.informatik.uni-dortmund.de>.
1496 Tue Sep 17 17:31:04 1991 Stu Grossman (grossman at cygnus.com)
1498 * coredep.c: include ptrace.h where necessary.
1499 * mipsread.c(parse_lines): fix unsigned char problem that was
1500 messing up line numbers on SGI's and possibly other MIPS based
1502 * infrun.c (child_create_inferior): use better test to check
1503 return val from setpgrp().
1504 * tm-irix3.h, xm-irix3.h, tconfig/irix3, xconfig/irix3: add these
1505 for sgi/irix support.
1507 Wed Sep 18 04:33:31 1991 Per Bothner (bothner at cygnus.com)
1509 * mipsread.c (parse_symbol): Put non-static procedures
1510 in the global block.
1512 Fri Sep 13 00:14:52 1991 John Gilmore (gnu at cygnus.com)
1514 Patch together `text_start' and `text_end' for 29K port.
1516 * exec.c (exec_command): If NEED_TEXT_START_END, define the
1517 variables and set them based on the exec file.
1518 * am29k-tdep.c: declare text_start.
1519 * valops.c (call_function_by_hand): declare text_end.
1521 * inferior.h: Eliminate CANNOT_EXECUTE_STACK in favor of
1522 defining CALL_DUMMY_LOCATION as BEFORE_TEXT_END. This is
1523 because machines that do this will also have to know to
1524 set NEED_TEXT_START_END. Besides, it was a redundant way to
1526 * tm-29k.h, tm-convex.h, tm-np1.h: Eliminate
1527 CANNOT_EXECUTE_STACK, define CALL_DUMMY_LOCATION and
1528 NEED_TEXT_START_END.
1530 Thu Sep 12 00:22:24 1991 John Gilmore (gnu at cygint.cygnus.com)
1532 AMD 29000 changes from David Wood <wood@david.ultra.nyu.edu>:
1534 * Makefile.in (CLIBS): Put XM_CLIBS and TM_CLIBS at end.
1535 Pass MUNCH_DEFINE to munch whenever we run it.
1536 * am29k-pinsn.c (print_insn): Handle NOP specially. Avoid %#x
1537 format string; use 0x%x instead.
1538 * am29k-tdep.c: Use DUMMY_SAVE_GREGS and RETURN_REGNUM.
1539 * ultra-xdep.c, xm-ultra.h: New files for Ultracomputer host system.
1540 * xm-rtbsd.h: New host support for RT/PC running BSD Unix.
1541 * inflow.c: Handle `short' process group IDs.
1542 * infptrace.c (fetch_register): Support CANNOT_FETCH_REGISTER,
1543 and check for ptrace errors.
1544 * coffread.c (SDB_REG_TO_REGNUM): Define if not already.
1545 (coff_symfile_init): Initialize text_bfd_scnum.
1546 (read_coff_symtab): Use it to find the text [and absolute?] sections.
1547 * ../config.sub: Add vendor nyu and os "sym[1-9]*".
1548 * configure.in: Add hosts rtpc-*-* and a29k-*-*.
1549 Merge target arm case with other "easy" cases. Add target
1550 cases a29k-*-none (rehack of am29k), a29k-*-kern (remote to
1551 Ultracomputer kernel), and a29k-*-sym1 (ultracomputer OS's user
1553 * minimon.h, remote-adapt.c, remote-mm.c: Add.
1554 * munch: Cope with RT/PC putting fns in data segment.
1555 Restore ability to override `nm' by specifying MUNCH_NM.
1556 * xconfig/rtbsd, xconfig/ultra3: New host systems.
1557 * tconfig/a29k: Rename from tconfig/am29k. Add remote-mm
1558 and remote-adapt. Remove encapsulated coff #define's (the
1559 support should go in BFD, and gdb shouldn't know or care).
1560 * tconfig/a29k-kern: Same, but for remote kernel debugging.
1561 * tconfig/ultra3: For debugging user processes on Ultra3/Sym1.
1562 * tm-29k.h: Update BADMAG (though it should go away).
1563 Allow the register definitions to be overridden in another
1564 tm-file. Fix SR_REGNUM. Add a mess of _REGNUM's. Separate
1565 RETURN_REGNUM from GR96_REGNUM and DUMMY_SAVE_GREGS from
1566 DUMMY_SAVE_GR96, for handling kernel calling conventions
1567 that use GR64+ rather than GR96+.
1568 * tm-ultra3.h: New file, for use on Ultra3 Unix as well as for
1569 remote debugging of Ultra3 kernel. Includes tm-29k.h and
1570 overrides various things.
1572 * remote-mm.c (mm_attach, mm_wait): Handle attach like
1573 child_attach does, making a clean stop in the newly attached
1575 * remote-eb.c: Lint.
1577 * coffread.c: Make coffread independent of any particular
1578 variant of COFF. Avoid #include-ing any particular one except
1579 internalcoff.h. BFD now passes key values for symbol reading
1580 as part of its coff_data structure (LINESZ, SYMESZ, AUXESZ,
1581 and the symbol masks and shifts); use them.
1582 Remove obsolete end_of_text_addr.
1584 * exec.c: Remove unused include files.
1586 Wed Sep 11 19:38:44 1991 John Gilmore (gnu at cygint.cygnus.com)
1588 * Makefile.in (documentation targets): Pass $(M4).
1589 Bugfix from eggert@twinsun.com (Paul Eggert).

1593 Tue Sep 10 23:08:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1595 * Makefile.in (VERSION): Update to 4.0.3.
1597 Tue Sep 10 09:19:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1599 * core.c (core_file_command): Print frame at coredump with
1600 its level number, by calling print_stack_frame.
1601 * frame.h: Add selected_frame_level, print_stack_frame.
1602 * frame.h, stack.c: Remove print_sel_frame, print_selected_frame.
1603 * convex-tdep.c, convex-xdep.c, infcmd.c, inflow.c, infrun.c:
1604 Change print_sel_frame and print_selected_frame callers to
1607 * dbxread.c (read_ofile_symtab): Avoid empty else clause.
1608 * symfile.c (free_named_symtabs): Ditto.
1609 * main.c (main): wrap_here needs an arg.
1610 * solib.c (find_solib): Avoid memory access if _DYNAMIC is zero.
1611 (solib_add): Avoid noise.
1612 (solib_create_inferior_hook): Lint.
1613 (sharedlibrary_command): Move dont_repeat to here.
1614 * utils.c (error): Call wrap_here to force buffered output.
1616 Small patches from Peter Schauer:
1618 * coffread.c (start_symtab): Free any existing line_vector before
1620 (read_coff_symtab): Ditto for type_vector.
1622 * source.c (lines_to_list): New variable, replacing function.
1623 (all uses): Use as variable.
1624 (_initialize_source): Add 'set listsize' and 'show listsize'.
1625 * utils.c (lines_to_list): Remove function.
1626 * stack.c (print_frame_info): Use as variable.
1627 * defs.h (lines_to_list): Remove declaration.
1629 Mon Sep 9 13:45:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1631 * breakpoint.c (insert_breakpoints): Restore warning about
1632 the program might be running in another process, but only for
1633 systems with this brain death (#ifdef ONE_PROCESS_WRITETEXT).
1634 * xm-hp300bsd.h, xm-mips.h, xm-vax.h: Define it.
1636 * utils.c (error): if error_pre_print is set, print the string
1638 * main.c (main, print_gnu_advertisement, print_gdb_version):
1639 Reformat legalese so it always prints, but acts as an "I'm here"
1640 message while symbols are being read. If any errors occur,
1641 print a few newlines to set off the message and start it at the
1642 left margin. Remove mention of "help" command, and don't yak
1643 about symbol reading.
1644 (catch_errors): Error string is now printed first in case of
1646 * command.c (undef_cmd_error, lookup_cmd): On undefined command,
1647 suggest the "help" command.
1649 * Makefile.in (VERSION): Set to 4.0.2.
1651 Thu Sep 5 23:49:48 1991 John Gilmore (gnu at cygint.cygnus.com)
1653 * .gdbinit: Remove useless "rr" command. Set complaints
1654 to 1 for people debugging gdb.
1656 * breakpoint.c, remote-vx.c: Reword strings printed by
1657 catch_errors callers.
1659 Wed Sep 4 11:07:50 1991 John Gilmore (gnu at cygint.cygnus.com)
1661 * WHATS.NEW: "history write -> history save". Doc "write on/off".
1662 (Fix from kenc@viewlogic.com.)
1664 Fix some infrastructure to be able to cope with host and target
1665 machines with different sized basic types (ints, ptrs, etc).
1666 (Idea from pierre@la.tce.com (Pierre Willard).)
1668 * values.c (value_from_longest): Rename from value_from_long.
1669 Handle pointer types as well as integers, so that targets with
1670 different pointer sizes from the host can be accomodated.
1671 * breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
1672 valarith.c, valops.c, valprint.c, value.h, values.c: Rename
1673 uses of value_from_long to value_from_longest.
1674 * eval.c, findvar.c, printcmd.c, valarith.c, valops.c: Pass
1675 the correct pointer type to value_from_long{est}.
1677 * doc/gdb.texinfo ($_, $__): Describe types of these variables.
1679 * remote-vx.c: Remove obsolete code for calling functions via
1680 vxworks kludge interface (it referenced value_from_long).
1682 * valops.c (value_string): Find malloc with lookup_misc_func, not
1685 Tue Sep 3 18:37:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1687 Make writing to files work properly. (Fixes to BFD are also needed.)
1689 * core.c (core_open): Open file ourselves, read or r/w, depending on
1690 write_files. Use bfd_fdopenr.
1691 * gdbcore.h (write_files): New variable.
1692 * exec.c (write_files): Define variable, add set&show for it.
1693 (exec_file_command): Use write_files to open for read or r/write.
1695 Make shared library reading happen automatically. These changes
1696 are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
1698 * inferior.h (stop_soon_quietly): Add to exported variables.
1699 * infrun.c (child_create_inferior): call solib hook, if defined.
1700 (child_attach): call solib hook, if defined.
1701 * solib.c: Include inferior.h. Add from_tty to so_list as kludge.
1702 (find_solib): Use lookup_misc_func rather than hand-rolled.
1703 (symbol_add_stub): New stub for catch_errors.
1704 (solib_add): Avoid output if !from_tty. Catch errors rather
1705 than just calling symbol_file_add and bombing.
1706 (solib_create_inferior_hook): Interface with the target process
1707 to let it read and alloc shared libs, then figure out what it did.
1709 * core.c (validate_files): Fix typo, soften warning.
1710 (Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
1712 * utils.c (fputs_demangled): Avoid duplicate printing if
1713 demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
1715 * infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
1716 (Fix from pierre@la.tce.com (Pierre Willard).)
1718 * main.c (catch_errors): Change argument to a char * from an int,
1719 since a char * can point to a struct full of glop, but an int
1720 is not guaranteed to be able to hold a pointer.
1721 * breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
1722 breakpoint_re_set_one, breakpoint_re_set): Adapt.
1723 * core.c (core_open, solib_add_stub): Adapt.
1724 * remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.
1726 Wed Aug 28 18:18:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1728 * Makefile.in: Update VERSION to 4.0.1. Evade GNU Make bug
1729 by adding .NOEXPORT target.
1731 Fri Aug 23 17:14:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1735 * Makefile.in (VERSION): Roll to 4.0.
1736 (gdb.tar.Z): Make refcard.ps as well, for shipment.
1738 Fri Aug 23 14:07:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1740 * doc/gdb.texinfo: minor rewordings, crossref to ptype from print,
1743 * doc/Makefile, Makefile.in: generate "gdb-all.texi" rather than
1746 * doc/rdl-apps.texi: renamed from rdl-apps.texinfo
1748 * Makefile.in, doc/Makefile, doc/.Sanitize, doc/gdb.texinfo:
1749 reflect above name change
1751 * WHATS.NEW: correct pointer to refcard.
1753 * doc/gdb.texinfo: update New Features, Installing
1755 * doc/gdbint.texinfo: add short description of configure +template
1757 Fri Aug 23 11:46:08 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1759 * doc/gdb.texinfo: update, fix bugs in "Installing" appendix
1761 Fri Aug 23 01:02:00 1991 John Gilmore (gnu at cygint.cygnus.com)
1763 * Makefile.in: Add config.sub, make doc/rdl-apps.texinfo for
1764 tar file, add dependencies for referenced doc files.
1766 Thu Aug 22 22:17:06 1991 Stu Grossman (grossman at cygint.cygnus.com)
1768 * coffread.c, symfile.c, stack.c: saberized.
1770 Thu Aug 22 16:20:27 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1772 * doc/refcard.tex: permuted Essential Commands sec
1774 * doc/gdb.texinfo: new C++ chapter; revised installation appendix;
1776 set/show symbol-reloading
1777 default set complaints 0
1779 RET-repeat disabled after prompted long displays
1780 processID (attach) interpretation of 2nd GDB cmdline arg
1782 Thu Aug 22 14:05:47 1991 Stu Grossman (grossman at cygint.cygnus.com)
1784 * expread.y, coffread.c, dbxread.c, target.c, mem-break.c,
1785 cplus-dem.c, values.c, valprint.c, symfile.c, remote.c,
1786 breakpoint.c, main.c: lint.
1788 Thu Aug 22 02:02:26 1991 John Gilmore (gnu at cygint.cygnus.com)
1790 Install new configuration scheme for GDB and friends.
1792 * config.sub: Translate ordinary names to three-part names.
1793 * configure: Use three-part names internally.
1794 * configure.in: Translate three-part names to filenames.
1796 * README, WHATS.NEW: Update for gdb-4.0.
1797 * Makefile.in: Roll VERSION to 3.99.
1799 Wed Aug 21 18:21:09 1991 John Gilmore (gnu at cygint.cygnus.com)
1801 * infptrace.c (KERNEL_U_ADDR_BSD): Include a.out.gnu.h.
1802 * i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
1803 tm-m68k.h, remote-nindy.c: Change ext_format_XXX structs
1804 to single structures rather than arrays; when passing
1805 their address, use &. This avoids trouble with bdead compilers.
1806 * mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
1807 instead. This avoids portability headaches.
1808 * mips-tdep.c (mips_do_registers_info): Only print FP regs if
1810 * source.c (open_source_file): Avoid ANSI const bdeath by
1811 skipping declaration and then casting result value.
1812 * tm-hp300bsd.h: Clarify comment.
1813 * utils.c (strstr): Result is const char *; ANSI bdeath.
1814 * xm-hp300bsd.h: Define HOST_BYTE_ORDER. Redefine INT_MIN,
1815 since system include file defines it differently from "defs.h",
1816 though the two are equivalent for our purposes.
1817 * tconfig/hp300bsd: Add m68k-tdep.o.
1819 Tue Aug 20 16:01:11 1991 John Gilmore (gnu at cygint.cygnus.com)
1821 * tconfig/sun*4: Remove warnings about system assembler.
1823 Mon Aug 19 13:44:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1825 * mcheck.c: Avoid warning about undeclared abort fn.
1826 * tm-sparc.h (PC_ADJUST): Avoid calling error() from this;
1827 it causes recursive calls to error() when used in cleanups.
1828 To do so requires that we make it a function, so we do.
1829 * sparc-tdep.c (sparc_pc_adjust): New implem of PC_ADJUST.
1830 * utils.c (do_cleanups): Remove the current cleanup from the
1831 chain *before* calling it, in case error() is called from it.
1832 The result won't be pretty, but won't be an infinite loop either.
1834 Mon Aug 19 00:41:04 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
1836 * dbxread.c (read_struct_type): Grok anon structs for C++.
1837 (vb_name, vptr_name): Null terminate these strings.
1839 Fri Aug 16 08:31:03 1991 John Gilmore (gnu at cygint.cygnus.com)
1841 Minor bug fixes from BSD Net2 gdb:
1843 * blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
1844 returns 0, there is no previous frame.
1845 * breakpoint.c (commands_command): If !from_tty, don't call
1846 input_from_terminal_p().
1847 * dbxread.c (record_misc_function): Speed up slightly.
1848 (compare_psymbols): Ditto.
1849 * infcmd.c (do_registers_info): Take a second argument to
1850 determine whether to print float registers. "info registers"
1851 does not do so anymore. "info all-registers" does, now.
1852 * mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
1854 * tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.
1855 * inflow.c (initialize_inflow): Set tflags_ours correctly.
1859 * breakpoint.c (bpstat_do_actions): Use a cleanup to restore
1860 executing_breakpoint_commands if we are interrupted by error.
1861 * coffread.c (init_lineno): Avoid problem with zero-sized linetab
1862 versus malloc/free. From: john@labtam.labtam.oz.au (John Carey).
1863 * core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a
1864 catch_errors() so we can setup the frame regardless of whether
1865 the shared libs work.
1866 * ieee-float.c (double_to_ieee_extended): Get exponent from
1867 right place in little-endian systems. From John Carey.
1869 Thu Aug 15 18:43:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1871 * main.c: Remove unused terminating_signals and catch_termination().
1872 (long_options): Terminate with a zero element.
1873 [Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
1874 (gdb_readline): Make call-compatible with readline.
1875 (init_signals): Improve comments re vfork vs. signal.
1877 * utils.c (prompt_for_continue): Use new gdb_readline().
1878 If we prompt for continuation, we don't let CR repeat the previous
1879 command, once we get back to a prompt. It's too easy to keep
1880 hitting CR, expecting "--more--" prompts, and have some long
1881 command start repeating on you.
1883 Tue Aug 13 16:17:56 1991 John Gilmore (gnu at cygint.cygnus.com)
1885 * blockframe.c (frameless_look_for_prologue): Speed up by
1886 calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
1887 * tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
1888 Define two variants, one faster.
1889 * sparc-tdep.c (sparc_frame_chain): Use target_read_memory
1890 and return zero, rather than giving an error.
1891 (setup_arbitrary_frame): Initialize the PC in the new frame.
1892 (skip_prologue): Add a second arg saying whether we're just
1893 checking for a frameless function or not.
1895 * core.c (core_open, core_close, core_xfer_memory): Move
1896 section table pointers and bfd* into the target_ops.
1897 (core_open): Allow errors in shared lib reading, etc.
1898 (core_files_info): Describe shared library sections.
1900 * exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
1901 exec_files_info, set_section_command): Move section table
1902 pointers and bfd* into the target_ops.
1903 (add_to_section_table): Add BFD to section table.
1905 * target.c (target_xfer_memory, target_info): Pass target to
1906 xfer_memory and target_info functions.
1909 * gdbcore.h: Move struct section_table.
1910 * target.h: New home of struct section_table.
1912 * solib.c (solib_add): New argument is the target_ops whose
1913 section list is to be added to, if any. Reallocate the
1914 sections in that target to add any that come from shared libs.
1915 (throughout) so_sections renamed to sections.
1916 (solib_xfer_memory): Deleted.
1917 * tm-sunos.h (SOLIB_ADD): Add target argument.
1918 (SOLIB_XFER_MEMORY): Delete.
1920 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
1921 remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
1922 from target_ops. It's the same on all targets. Add two section
1923 pointers to target_ops.
1925 * stack.c (find_relative_frame): Dump ancient algorithm for
1926 "down", just use handy "next" pointers.
1927 (frame_command): Don't error if there is no stack; let user
1930 * inflow.c (new_tty_prefork, new_tty): New prefork routine
1931 modifies static state in the parent process; new_tty itself
1932 runs in the child and modifies the child's file descriptors
1933 to match the saved static state.
1934 * infrun.c (child_create_inferior): Call new_tty_prefork,
1937 * infptrace.c (child_xfer_memory): Add ignored target arg.
1938 * remote-eb.c (eb_xfer_inferior_memory): ''
1939 * remote-nindy.c (nindy_xfer_inferior_memory): ''
1940 * remote-vx.c (vx_xfer_memory): ''
1941 * remote.c (remote_xfer_memory): ''. Rename from
1942 remote_xfer_inferior_memory.
1944 * main.c (main): Only try to attach "corefile" argument if
1945 it starts with a digit.
1947 * symfile.c (symbol_reloading): New "set/show" variable.
1948 (symbol_file_add): Shorten message about symbol reading.
1949 (add_symbol_file_command): Merge with add_syms_addr_command,
1950 since this should work on all targets now.
1951 (stop_whining): Default to zero, to shut up complaints
1952 about bad symbol tables on many systems.
1953 (free_named_symtabs): Just exit unless symbol_reloading.
1955 * xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
1956 and add comment explaining shared library screw.
1958 * source.c: #if defined => #ifdef.
1960 Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
1962 * doc/gdbint.texinfo: Improve doc on porting to new OS's.
1964 Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1966 * doc/rdl-apps.texinfo: provide default readline-appendix finder
1967 (doc/Makefile knows how to make one for local config)
1969 * Makefile.in: use doc/Makefile for doc targets
1971 * doc/Makefile: GDB documentation now has its own Makefile
1972 doc/refcard.tex: renamed from "gdbrc.tex"
1973 doc/.Sanitize: add Makefile; recognize renamed refcard.tex
1974 doc/gdbint.texinfo: add markup in "Cleanups" chapter
1977 Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1979 * values.c (baseclass_addr): When reading target memory, use the
1980 length of the basetype, not the upper type. We've only malloc'd
1981 enough space for the basetype, leading to errors in free().
1983 * expprint.c (print_subexp): Print UNOP_MEMVAL of an OP_LONG that
1984 ends up as a function specially, since we know the actual type of
1985 the pointed-to address. This (somewhat) fixes display of
1986 expressions that include misc_function_vector names. Try `cond 1
1987 !strcmp("a","b")' then `i b'.
1989 * infrun.c: Move DO_DEFERRED_STORES from proceed() to resume().
1990 The child can be proceeded from inside wait_for_inferior in
1991 evaluating breakpoint conditions, and DO_DEFERRED_STORES was
1992 getting skipped in that case.
1994 * expprint.c (print_subexp): Use filtered output, since the
1995 subroutines we call use it, otherwise the output is horribly
1996 mangled, since output of wrappable stuff comes out late.
1998 * Makefile.in: Bump VERSION to 3.98.1
2000 * infrun.c (child_create_process): Use execlp to find the
2001 shell to exec our target program. This requires some fiddling
2002 with `environ' since there is no execlpe().
2004 Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2006 * Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
2007 Minor rearrangement of refcard permits two new make targets--
2008 gdbrc.dvi DVI output for refcard, using CM fonts
2009 gdbrc.ps PostScript refcard, using PS fonts
2011 Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
2015 * TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
2016 * Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
2018 Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2020 * doc/gdb.texinfo: last changes for release.
2021 Minor typo and formatting fixes; incorporated most fixes remaining from
2022 filed mail commenting on earlier drafts.
2024 Added warnings: pipes don't work in run command;
2025 conditions are converse of assertions;
2026 step over fn without debug info goes to next fn;
2027 vars may have "wrong" values near fn entrance, exit
2029 Added example from Kingston on printing repeated nonadjacent values
2031 Added explicit mention that in Emacs gdb mode C-c and C-z are like
2032 shell mode for signals
2034 Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
2035 doesn't sound so much like its parent "Stopping and Continuing"; also
2036 moved entries on continue to top of section, so they don't get lost.
2038 Improved installation directions in appendix, added manual formatting
2041 Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
2043 * configure.in: Remove xm.h and tm.h even if we aren't linking
2044 new ones, so "./configure sun4; ./configure none" does the right
2045 thing. Assume that alldeps.mak and depend are already built in
2046 srcdir, and avoid running "make" (particularly "make depend",
2047 which involves "gcc") from inside configure. Build Makefile
2048 directly rather than building Makefile.conf first.
2049 * configure: Regenerate with above changes.
2050 * Makefile.in: Use $(BISON) to find bison. Roll VERSION
2051 to 3.98. Revise gdb.tar.Z procedure to produce a file
2052 called gdb-$(VERSION).tar.Z but which unpacks into a
2053 directory called "gdb". Move non-source files out of
2054 $(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
2055 (depend): Don't try to do "gcc expread.y".
2056 (expread.o): Update dependencies by hand.
2058 Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2061 Fixed a variety of small typos that prevented info from formatting
2062 cleanly; altered too-long heading for GPL Appendix, as discussed
2063 w/RMS; Changed date on cover to July 91.
2065 Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2068 (1) Applied some fixes due to comments from Larry Breed (easier ones
2069 through chapsec 5.2)
2070 (2) Eliminated use of @footnote---had my doubts about it anyways, and
2071 it's broken in latest texinfo
2072 (3) Introduced *some* use of [] for optional arguments, where
2073 explanation is not simpler by listing cmd w arg and cmd w/out arg
2074 separately. Still not using @deffn.
2075 (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
2076 couple of headings are too long. Need patches to texinfo or revision
2079 * Partial update to README (which still needs work for this
2080 release!): (1) use of configure corrected for new script,
2081 (2) "make gdb.dvi" and "make gdb.info" mentioned.
2083 Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
2085 * symtab.c (lookup_symbol): Don't complain right off about
2086 no debug symbols; use the misc function vector first.
2087 (list_symbols): Use misc function vector to find symbols
2088 that don't have debug info, and print them.
2089 (find_pc_symtab): Temporarily avoid fatal() when psymtab
2090 PC range doesn't match symtab PC range, as it does on the
2091 MIPS because our symtab reading isn't perfect.
2093 * dbxread.c (dbx_symfile_read): Make warning about
2094 "no debug symbols" slightly nicer.
2096 * source.c (select_source_symtab): If "main" symbol exists,
2097 but decode_line_spec can't find line info, don't just return
2098 a zero; try other source symtabs or give an error.
2100 * mipsread.c (parse_partial_symbols): Sort the psymtabs by
2101 their low addresses first, then rip through fixing high addrs.
2103 * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
2104 <runene@ifi.uio.no>.
2105 (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
2107 Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2109 * Minor, mostly mechanical, cleanup of doc subdir for clean
2110 makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
2111 and gdb.info (post- texinfo2 makeinfo) generated for distribution.
2113 Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
2115 Mostly MIPS and general symbol-reading fixups.
2117 * doc/gdbint.texinfo: Add documentation on symbol-reading
2120 * mipsread.c: Remove kludges around #include "ecoff.h".
2121 Remove redefinitions of a_magic, etc, no longer used.
2122 (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
2123 Fix global overview comments to match symfile.c protocol.
2124 (mipscoff_new_init): Eliminate cur_hdr if we have one.
2125 (mipscoff_symfile_read): Eliminate unused code. Avoid
2126 sorting all the symtabs, when all we have read here is psymtabs.
2127 The symtabs are sorted as they are created anyway. Tell
2128 condense_misc_bunches whether we're mainline.
2129 (psymtab_to_symtab_1): Pass filename when recursing, to make
2130 stack trace more informative.
2131 (parse_partial_symbols): Assume cur_hdr as argument.
2132 (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
2133 Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
2134 the TYPE_NAME of char *, since that's done in symfile.c.
2135 (free_numargs, parse_symbol, add_symbol, add_block,
2136 shrink_linetable): Declare these fns void.
2137 (upgrade_type): Convert tree of if's to switch. Clean up
2138 bogus "off == 0" handling with a complaint. Avoid setting
2139 field bitpos and bitsize of array with lower and upper bounds.
2140 Check specified bitsize of elements against their actual type's
2141 bitsize, and complain if different. Complain about unknown
2143 (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
2144 (psymtab_to_symtab_1): Print names of subsidiary files that
2145 are being read in. FIXME, we read far too many files. This code
2146 is not the problem, the problem is in parse_fdr where the psymtabs
2148 (cross_ref): Result should indicate that we used one aux entry
2149 normally, or two if we encountered a "next" entry. This used
2150 to leave the caller pointing at the wrong aux entry.
2151 (add_symbol): If overflowed cur_block, reallocate it larger,
2152 chase all pointers to it, and complain(), rather than clobber memory.
2153 (shrink_block): Use xrealloc rather than xmalloc-and-copy.
2154 (new_field): Only allocate one field initially, not two.
2155 Pull ++ out of macro argument. Simplify.
2156 (_initialize_mipsread): Avoid initialization of importd
2157 global_psymbols and static_psymbols.
2159 * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
2160 to properly set pst->symtab; avoid searching for it.
2161 (symfile_fns): Improve comments, add a FIXME.
2162 * dbxread.c: Update comments to reflect symfile protocol.
2163 (read_ofile_symtab, end_symtab): Return the symtab.
2164 (psymtab_to_symtab_1): Set pst->symtab.
2166 * coffread.c (coff_symfile_read): tell condense_misc_bunches
2167 whether we're mainline.
2169 * symfile.h (sym_fns): Remove unused sym_discard member.
2170 * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
2172 * mtrace.c (mtrace): Take effect if mallwatch is set, even if
2173 the environment variable is not.
2174 * infcmd.c (finish_command): Use filtered printfs.
2175 * cplus-dem.c: Add struct tags to a few unnamed structs.
2176 * valops.c (value_coerce_array): Improve comments.
2177 * valprint.c (type_print_varspec_suffix): Print array size only
2178 if greater than zero.
2179 * m88k-tdep.c: Shift some lines left by one space, that had
2180 apparently been trashed at some point.
2181 * TODO: More things to do, a few got done.
2183 Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
2185 * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
2186 (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
2188 * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
2189 * expread.y, findvar.c, symmisc.c: Ditto.
2190 * printcmd.c (address_info): Update printed forms of LOC_
2191 symbols. Elim LOC_EXTERNAL.
2192 (print_frame_args): Keep track of param stack offsets before
2193 re-looking up to find the local register param is kept in.
2195 * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
2196 Further integration of mipsread into gdb. Eliminate unused
2197 routines, duplicate declarations. Handle static symbols in
2198 psymtabs as well as external symbols. When reading symtabs,
2199 insert symbols into the correct block (global, static, or a local
2201 (read_mips_symtab, parse_partial_symbols): Don't pass useless
2203 (mipscoff_symfile_read): Don't call select_source_symtab.
2204 (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
2205 rather than SYMBOL_VALUE.
2206 (parse_external): Comment clobbering of top_stack.
2207 (parse_partial_symbols): Update comments. Allocate and parse
2208 static symbols as well as external symbols. FIXME, enum values
2209 are not handled in this pass, but should be. Inline new_psymbol.
2210 Use SYMBOL_VALUE_ADDRESS.
2211 (psymtab_to_symtab_1): Read symbols into global static block
2212 by default (until enter some function's local block context).
2213 (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
2214 (destroy_all_symtabs, new_psymbol): Eliminate, unused.
2216 * source.c (select_source_symtab): Select a source symtab
2217 from either the symtabs or, failing that, the psymtabs.
2218 (list_command): Update error message.
2219 (forward_search_command, reverse_search_command): Use getc, not
2220 fgetc, for speed. FIXME, add comment about buffers that die if
2221 overrun by long line.
2223 * values.c (unpack_field_as_long, modify_field): Avoid shifting
2224 by an entire word, which is not portable, if we have a 32-bit
2225 field. (Code in dbxread.c already turns such bitfields, if
2226 aligned, into ordinary ints, but fixing this will help for other
2227 symbol formats and for future changes.)
2228 * core.c (core_open): Handle ANSI const brain death.
2229 * utils.c (vprintf): Fix varargs typo.
2231 Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
2233 * findvar.c (find_var_value): Handle &function better.
2234 * TODO: Document work needed on &fn and &array.
2235 * printcmd.c (print_address_symbolic): New arg is the prefix
2236 to print if a name is printed.
2237 (print_address_demangle): Honor "set print address" now.
2238 Use new arg above to improve spacing of output.
2239 * valprint.c (val_print): When printing function pointers,
2240 print symbolic form too.
2241 * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
2243 Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2245 * core.c (memory_error): Reword error msg to mislead less.
2247 * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
2249 * mipsread.c (read_mips_symtab, read_the_mips_symtab,
2250 parse_partial_symbols): Use newer BFD internals (external_filehdr
2251 and external_aouthdr), byte-swap the fields that we care about
2252 before using them, and make the file header data local to
2253 read_the_mips_symtab rather than global.
2255 Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
2257 * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
2258 from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
2260 * main.c (command_line_input): Flush stdout and stderr
2261 before every call to readline. This reportedly fixes a bug
2262 that comes up in Sys V running emacs-gdb and/or xxgdb,
2263 when stdin/out are pipes or sockets.
2265 Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2267 * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
2268 Avoid declaring Makefile dependencies, because GNU Make stupidly
2269 tries to update it if we do.
2271 * coffread.c: Revise for minor changes to bfd internal coff
2274 * configure: If -template= is given a relative path, make it
2275 absolute before recurring in subdirectories.
2277 * configure, configure.in, Makefile.in: Install "configure" script
2278 as replacement for config.gdb.
2279 * config.gdb, Makefile.dist, Makefile.sdir: Remove
2280 * README: Update for configure, mostly. FIXME.
2282 * Add dec3100 as equivalent to littlemips. Indicate in all host &
2283 target config files that they are for the host. When the lines
2284 get copied into the Makefile, this makes it more obvious what's
2287 Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2289 * sparc-opcode.h (trap opcodes): Avoid leading spaces or
2290 tabs, which end up in the disassembler output inadvertently.
2292 Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
2294 Make it compile cleanly in an ANSI GCC2 environment.
2296 * blockframe.c: <stdio.h>
2297 * cplus-dem.c: free takes a void *, ifdef __STDC__
2298 * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
2300 * defs.h (alloca): Avoid doing anything if alloca already def'd.
2301 * stddef.h, stdlib.h: Remove these files.
2302 * symtab.c: Avoid declaring qsort, close.
2303 * symfile.c: Avoid declaring close.
2304 * utils.c (vprintf): Declare "ap" arg as proper va_alist.
2305 * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
2307 Assorted other changes.
2308 * dbxread.c: include "libaout.h", not "liba.out.h".
2309 * printcmd.c (print_frame_args): Set recurse properly for
2310 indentation of struct and array parameters.
2311 * valops.c (value_cast): Allow cast to void.
2312 * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
2313 single_step() in a target-independent fashion.
2314 * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
2315 set up to be ready to continue. This makes us target independent.
2316 * infptrace.c (child_resume): Remove call to single_step; now
2317 can single step a SPARC target of any kind.
2319 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2321 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
2322 docn into separate sections---basically chapters, plus two loose
2323 pieces that can be configured to go in different places. This
2324 allows GNU m4 to preprocess the manual without coredumping.
2326 * Makefile.dist: tell TeX where to find texinfo.
2328 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2330 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
2331 the new target "rdl-apps.texinfo" which captures the Makefile
2332 variable that records where to find the Readline libraries.
2334 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
2336 * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".
2337 * tm-tahoe.h (FIX_CALL_DUMMY): Ignore more parameters.
2338 * defs.h (const, volatile): Only define if not already defined.
2339 * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
2341 * README: Update for release 3.95.
2342 * config.gdb: Don't create readline dir in subdir builds.
2343 * main.c: Include with "..." form for non-system include files,
2344 so "gcc -MM" for "make depend" works.
2345 Include readline files with "...h" rather than <readline/...h>.
2346 * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
2348 * coffread.c: Undo minor damage done by Rich Pixley. Use
2349 different internal and external representations of COFF
2350 data structures. Use new BFD routines for swapping them in and
2352 * symfile.c (free_named_symtabs): Avoid freeing file names that
2353 are null or empty. Old i960 tools seem to produce files that
2354 claim to have empty names, causing each successive file read
2355 to blow away the previous one.
2356 * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
2357 Move deferred_stores to top of file, but don't separate its
2358 #define's from its variable. Add commentary.
2359 * Makefile.dist: Fix Rich damage; undo "configure" changes in
2360 favor of keeping the (working) config.gdb. Move readline
2363 Fri May 17 12:49:56 1991 Per Bothner (via gnu at cygint.cygnus.com)
2365 * dbxread.c (read_struct_type): Try to handle g++ version 1 MI
2367 * infptrace.c (fetch_registers): no result, since now void.
2368 * tconfig/news: target depends on m68k-tdep too.
2370 Fri May 17 14:40:14 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2372 * Makefile.dist: added readline/inc-*.texinfo to dependencies for
2375 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
2376 applied various small fixes due to or inspired by RMS comments
2378 * doc/gdb.texinfo: finished using all RMS comments, save those for
2379 appendices on readline and cmd history (which are in other source
2382 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2384 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
2385 chapter 9; (2) documented 'break' command's menu mode for
2386 overloaded names, in response to hgs problem report C++ p-31
2388 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2390 * doc/gdb.texinfo: (1) better introductory example; (2) more
2391 consistent use of @code, @samp, @file, @kbd throughout; small
2392 cleanups to first three nodes; (3) new "Contributors" node;
2393 (4) Appendix, Renamed Commands; (5) divert specialized startup
2394 instructions to "Targets" chapter for generic manuals, while
2395 leaving them up front for manuals specific to specialized
2396 environments; (6) apply fixes from RMS comments through chapter 4.
2398 * pretex.m4: modify explanatory text slightly (and redefine
2399 "regexp") to keep GNU m4 from complaining. (It still crashes
2400 later, but one step at a time...)
2402 Wed May 15 10:32:12 1991 John Gilmore (gnu at cygint.cygnus.com)
2404 * readline/readline.c (update_line): Avoid dereferencing a pointer
2405 before comparing it to its bounds. Saber caught this.
2406 (init_terminal_io): Don't set BC from the "pc=" termcap variable,
2407 and only set PC if tgetstr returned non-null. Saber caught this.
2409 Tue May 14 16:29:53 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2411 * Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
2412 stuff for config manual) here where it counts; updated
2413 to use new subdir structure (gdb/doc/).
2415 * Makefile: generated from above via
2419 * gdbint.texinfo: added instructions on generating gdb.info* files
2420 locally for release. These are ordinary info
2421 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
2422 Makefile)---but due to use of texinfo 2, can't count on makeinfo

2906 tm-sun3.h: Define TARGET_SUN3.
2908 * utils.c: Use CPLUS_MARKER not '$'.
2910 * cplus-dem.c: Use CPLUS_MARKER not '$'. If CPLUS_MARKER isn't
2911 defined, define it to '$'.
2913 * arm-opcode.h: New file (same contents as before; it had
2914 just been left out of the distribution for a long time).
2916 * tm-68k.h: Put declaration of ext_format_68881 outside the macros.
2918 * main.c: New HAVE_SIGSETMASK #ifdefs.
2920 * coffread.c (read_coff_symtab): Check for "LF%" with all the
2923 * coffread.c (SDB_TYPE): New macro.
2924 various: Use it instead of checking against T_NULL.

2935 * i386-pinsn.c (OP_E): Change %d to 0x%x for consistency.
2937 * putenv.c: New file
2938 Makefile.dist: Add it to $(OBS).
2940 * mipsread.c [!CMUCS]: #include <syms.h>.
2942 * mips-xdep.c (fetch_core_registers): #if 0 out the whole function.
2944 * Move read_memory_nobpt from mem-break.c to breakpoint.c.

2948 * utils.c (_initialize_utils): Rename "set demangle" to
2949 "set print demangle", "set asm-demangle" to "set print

2984 * inftarg.c (child_open), remote-vx{,.68}.c (vx_proc_open):
2985 New function to give correct error message.
2987 Thu Apr 11 17:19:41 1991 Jim Kingdon (kingdon at cygint.cygnus.com)
2989 * target.h: Add to_doc and target_preopen.
2990 target.c: Add target_preopen and target_command.
2992 (add_target): Call add_cmd and mess with targetlist->doc.
2993 core.c, exec.c, remote-eb.c, remote-nindy.c, remote-vx.c,
2994 remote-vx.68.c, inftarg.c, remote.c: Add doc field to target struct.
2995 Call target_preopen from open routine.
2997 * main.c: Rename editing_info to show_commands.
2998 (_initialize_main): Rename "info editing" to "show commands".
3000 * source.c: Rename directories_info to show_directories.
3001 (_initialize_values): Rename "info directories" to "show directories".

3012 Rename add-syms to add-symbol-file.
3014 Thu Apr 18 18:08:30 1991 John Gilmore (gnu at cygint.cygnus.com)
3016 * symfile.h (free_named_symtabs): Rename from free_named_symtab.
3017 * symfile.c (clear_symtab_users_once, cashier_psymtab,
3018 free_named_symtabs): Move these routines from symmisc.c.
3019 * symmisc.c (same): same.
3020 (free_symtab): Make non-static.
3021 * symtab.h (free_symtab): Declare as exported void fn now.
3022 * dbxread.c (end_symtab, end_psymtab): Change comments.
3023 (initialize_dbxread): Call dbx_new_init() in case the first
3024 command is add-symbols.
3025 * target.c (dummy_target): Permit add_syms_addr_command.
3027 Sat Apr 13 14:46:07 1991 John Gilmore (gnu at cygint.cygnus.com)
3029 Permit symbols to be superseded when new symbol files have
3030 been read in, particularly for VxWorks.
3032 * dbxread.c (read_dbx_symtab): Allow N_SOL to cleanly take us back
3033 to the main file, as well as to include files. Also, put global
3034 functions into the global psymtab, to make "i fun" work.
3035 (end_psymtab): Free named symtabs and psymtabs for a file, once a
3036 new psymtab for it has been read.
3037 * coffread.c (end_psymtab): Free named symtabs and psymtabs for
3038 a file, once a new symtab has been read for it.
3039 * mipsread.c: FIXME. We need to do the same for MIPS, but it
3040 looks harder to determine the top-level block before it's been
3041 queued to the psymtab list.
3043 * symfile.c (symbol_file_add): Use filtered printing and wrap it.
3044 If we have wiped out any old symbol tables, clean up at end of
3046 (symbol_file_command): Don't reference symfile_fns if it's zero.
3048 * symtab.h (GLOBAL_BLOCK, STATIC_BLOCK, FIRST_LOCAL_BLOCK): New
3049 defines for the blocks of a blockvector that contain global and
3050 file-static symbols and the first of the smaller scope contours.
3051 * symtab.c (lookup_symbol, find_pc_symtab, find_pc_line,
3052 decode_line_1, make_symbol_completion_list): Use the above.
3053 * coffread.c (end_symtab, patch_opaque_types): Ditto.
3054 * dbxread.c (end_symtab): Ditto.
3055 * expread.y (block): Ditto.
3056 * mipsread.c (throughout): Ditto.
3057 * symmisc.c (free_named_symtabs): Ditto.
3059 * symtab.c (list_symbols): Process the first symbol of the
3060 static psymbols list.
3061 (types_info): Restore this function from its untimely #if 0.
3062 It's not perfect, but it is better than nothing.
3063 (_initialize_symtab): Restore "info types".
3065 Thu Apr 11 05:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
3067 * m68k-stub.c: Remote stub for 680x0's, created from
3068 rem-m68k.shar (which is removed).
3069 * nindy-share/{Makefile,Onindy.c,blout.h,env.h,nindy.c,ttyflush.c}:
3070 Remove RCS log stuff now that we use CVS and it blows our diffs.
3072 Wed Apr 10 14:18:06 1991 John Gilmore (gnu at cygint.cygnus.com)
3074 * symmisc.c (free_named_symtab): Make it work, in its current
3075 kludgy fashion. Change result to indicate if we blew away bkpts.
3076 * dbxread.c (end_symtab): Accumulate result from
3077 free_named_symtab and print warning if we blew user's state.
3078 * symfile.h: free_named_symtab now returns an int.
3080 Mon Apr 8 23:57:43 1991 John Gilmore (gnu at cygint.cygnus.com)
3082 * dbxread.c (dbx_symfile_read): Initialize psymbol list if this
3083 is the first symbol read, even if not mainline.
3084 (dbx_psymtab_to_symtab): symfile might be zero, cope.
3085 * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
3086 (set_section_command): New command ("section xxx yyy" -- should
3087 be renamed to "set section xxx yyy" FIXME) which sets the
3088 base address of a section of the exec file, overriding the
3089 virtual address that BFD reports.
3091 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
3093 * exec.c: Add add_syms_addr_command to exec_ops, so you can
3094 load symbols at any address while examining an exec file.
3096 Thu Apr 4 10:09:35 1991 John Gilmore (gnu at cygint.cygnus.com)
3098 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
3099 for printing the float info is host-dependent, not
3100 target-dependent. FIXME.
3101 * i386-pinsn.c: Move #includes to top, remove useless ones.
3102 * i386-tdep.c: Don't bother including <.../reg.h> since we
3103 don't use it (and it doesn't exist on host systems).
3105 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
3106 Convert negative numbers properly.
3107 (ieee_test): Make numbers really random; fix format arg.
3109 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
3110 * core.c (core_detach): Unpush core_ops, which might not be on
3111 top. We used to just pop the top, which broke things. Don't
3112 need dont_repeat() any more.
3113 (core_file_command): Psst! Don't repeat it.
3114 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
3115 * expprint.c (print_subexp): Avoid switch fallthru on
3116 BINOP_ASSIGN_MODIFY, so we can print += and such.
3117 * frame.h: Fix typo.
3118 * inflow.c (kill_command): After killing inferior, print our
3119 current frame in the core file, if we have one.
3120 (generic_mourn_inferior): When inferior dies, either select
3121 the current frame (in the new target, e.g. core file), or
3122 set both the current and selected frames to NULL.
3124 Changes from Peter Schauer.
3126 * infptrace.c: Avoid <sys/ptrace.h> on USG.
3128 * Make all file names fit in 14 characters (sigh and damn!):
3129 mv hp300hpux-xdep.c hp300ux-xdep.c
3130 mv symmetry-xdep.c symm-xdep.c
3131 mv symmetry-tdep.c symm-tdep.c
3132 mv convex-opcode.h convx-opcode.h
3133 mv tm-vxworks960.h tm-vx960.h
3134 mv tm-vxworks68.h tm-vx68.h
3135 mv Makefile.srcdir Makefile.sdir
3136 mv gdb-int.texinfo gdbint.texinfo
3137 mv remote-sa.m68k.shar rem-m68k.shar
3138 mv remote-multi.shar rem-multi.shar
3139 * Makefile.dist, README, config.gdb, convex-pinsn.c,
3140 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
3141 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
3144 * command.c (user_info_1, user_info): New command for listing
3145 the user-defined commands.
3147 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
3149 * dbxread.c (really_free_pendings): Clear file_symbols
3150 and global_symbols after freeing them; otherwise, running
3151 this function twice (if it appears twice on the cleanup
3152 chain), we try to free things twice.
3154 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
3155 based on text_addr (the address of text in core), not on addr (the
3156 offset between text in the .o file and in core). This change
3157 is from Peter Schauer.
3159 * main.c: Define ALL_CLEANUPS as a cast of zero.
3160 (return_to_top_level): Use it.
3161 (main): Do all cleanups after each command run as part
3162 of the gdb startup sequence. Also do all cleanups before
3163 entering the command loop, and every time we exit the command
3164 loop and reenter. Before, the cleanups from the startup sequence
3165 were being left undone until the first error!
3166 (command_loop): Rename do_nothing cleanup to command_loop_marker
3167 so we can see it easily when examining the cleanup chain.
3168 (init_signals): Add another do_nothing for signal handling.
3169 (quit_command): Only try to kill target if it has execution.
3170 Problems in the target stack got us into a state where
3171 inferior_pid was nonzero but none of the targets had execution.
3172 In this state you couldn't exit gdb.
3174 * dbxread.c: Two changes from Peter Schauer.
3175 (echo_command): Fflush output after an echo command.
3176 (show_history): Pass all args to cmd_show_list.
3178 * utils.c (init_malloc): Call mtrace to turn on tracing
3179 if the environment variable MALLOC_TRACE is set to a file name.
3180 * mtrace.c: Add source file which provides a log of every malloc,
3181 free, and realloc to a trace file.
3182 * mtrace.awk: Add source file which analyzes the trace file.
3183 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
3184 (VERSION): Roll to 3.94.3.
3186 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
3187 (check_duplicates): Don't bother with watchpoints.
3188 (set_raw_breakpoint): Comment about danger of this routine.
3189 (watch_command): Parse and eval all args before calling
3192 * solib.c (find_solib): Avoid error in referencing memory to
3193 see if any more shared libraries have been added. This is
3194 particularly useful if the target has terminated. Bug reported
3197 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
3198 in bringing up 3.94.2 on the Sun-3.
3200 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
3201 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
3202 expression (in scope) before reenabling watchpoint.
3203 * signame.c (init_sigs): Add missing declaration of i, fix
3204 sys_siglist declaration.
3205 * source.c (list_command): Fixed range computation to use
3207 * stack.c (backtrace_command): Do not allow command if target has
3208 no stack, print informative error message.
3209 * target.c (target_command): Do not write into command line
3210 because this fails if the target command is used in a user defined
3211 command. [This change was enhanced by gnu to support any-
3212 unique-prefix matching on target names.]
3213 * valops.c (value_struct_elt): Avoid infinite loop on an
3214 erroneous attempt to print the member of function (try p main.p).
3216 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
3218 * expread.y (name_no_typename): Avoid reduce/reduce errors
3219 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
3220 Since the GDB parser really doesn't use name_no_typename in a
3221 name-only context, the parser can't tell the diff between
3222 names and numbers here. Avoid allowing a name_no_typename
3223 to be a NAME_OR_*INT to resolve the conflict.
3225 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
3227 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
3229 * valprint.c (val_print_fields): bitfield printing didn't handle
3230 byte order. Indirect through a few more fns to cope.
3232 * values.c (modify_field): also cope with byte order.
3234 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
3236 Cleanup for release 3.94.2:
3238 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
3239 include files. Roll version to 3.94.2.
3241 * coffread.c (init_stringtab): Read length into unsigned char
3242 array before swapping; don't assume 32-bit longs.
3244 * target.c (target_info): Don't bother with get_sym_file, just use
3245 the symfile global variable.
3246 * symtab.h, symfile.c (get_sym_file): Delete it.
3248 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
3249 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
3250 (read_type): Replace one more error() with complain().
3252 * mipsread.c (parse_partial_symbols): Replace printf with complain.
3254 * i960-tdep.c: Fix copyright attribution.
3256 * config.gdb: Quote all backquotes in doublequotes. You can
3257 quote me on that. BSD 4.4 shell found this one.
3259 * infptrace.c (throughout): The third argument to ptrace is an
3262 * infrun.c (wait_for_inferior): When program has terminated, we
3263 have to call target_terminal_ours before we pop that target off
3264 the stack (e.g. before a call to target_kill or
3265 target_mourn_inferior). This fixes problem where a program
3266 terminates, then GDB stops for (tty output) and you have to type
3267 "fg" to the shell to resume it. FIXME: This code for what to
3268 do after termination really should be in normal_stop instead.
3270 * gdbcore.h (read_memory_check): Change declaration; it changed
3273 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
3274 4.4 prereleases, this avoids a bug in their sgtty compatability
3276 * remote.c: Use terminal.h rather than hand-rolling the same.
3278 * signame.c, signame.h (psignal): Arg is unsigned, not int.
3279 * utils.c (strsave, strstr): Fix arg types.
3280 * valprint.c (val_print): lint
3282 MIPS symbol table support from Per Bothner:
3284 * symfile.c (symtab_fns): Remove initializer table that needs to
3285 be hacked for each new symbol file format supported.
3286 (add_symtab_fns): New function, chains symbol table
3287 handlers into the global list.
3288 (symfile_init): Search this list.
3289 * symfile.h: Add next pointer, declare add_symtab_fns.
3290 * coffread.c (_initialize_coffread): Call add_symtab_fns.
3291 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
3293 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
3294 symbol *). Thus, we no longer need the hack to trash
3295 pst->filename. Good, since that hack confused code in symfile.c!
3297 (reorder_symtabs, destroy_all_symtabs): Removed static
3298 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
3299 Instead, the latter now uses a temporary array (stack-allocated
3300 from an obstack, and then freed).
3302 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
3303 haven't been set in the outermost stBlock of a procedure. This was
3304 a problem with f77 binaries on Ultrix 4.?.
3306 (new_symtab, new_symbol, new_type): Continue changing code to use
3307 obstacks more and otherwise conform to dbxread internal style.
3308 Made the free_code of symtabs be free_linetable (as in dbxread)
3309 instead of free_contents. This implies memory leaks when reading
3310 a new symbol table, until the conversion is finished. Did change
3311 (struct symbol) and (struct type) to be allocated on the
3312 symbol_obstack. Blocks and blockvectors are among the things
3315 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
3316 tested much, but it solved one problem (reported by Meissner), and
3317 cleans up some other things. The problem happened when an
3318 included file contains actual code (functions) and not just
3319 definitions. The mips coff is a little inconvenient there, since
3320 it may cause a procedure to be mapped to the wrong psymtab.
3322 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
3323 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
3324 this will need work for the new core paradigm.
3326 Opcode patches from the net:
3328 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
3329 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
3330 missing altogether - they are added here. From Bruce Bauman.
3331 * mips-opcode.h: The low mask for C0 instructions was too small.
3332 From Garrett Lau. I modified the fix to check the entire 32-bit
3335 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
3338 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3340 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
3342 * dbxread.c (read_type): Pointer subtraction (value_sub in
3343 valarith.c) sometimes failed because the types of the
3344 pointers being subtracted were not identical.
3345 These differed because dbxread.c was allocating pointer types
3346 using dbx_alloc_type+smash_to_pointer_type instead of
3347 lookup_pointer_type. I failed to find a justification for the
3348 former, so I changed it to use the latter. Similarly, I
3349 replaced smash_to_function_type by lookup_function_type,
3350 and smash_to_reference_type by lookup_reference_type.
3352 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
3353 _initialize_mipsread): corresponding changes.
3355 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
3357 * source.c (mod_path): Do tilde_expand on each component of the path,
3358 rather than on the (list of) paths as a whole.
3359 (print_source_lines): Set first_line_listed in addition to
3360 current_source_symtab and current_source_line. If the source was
3361 not findable, after a "dir" command to fix the problem,
3362 a "list" would get the wrong lines.
3364 While I was there... (gnu):

3376 (): FIXME: Should realloc-down the psymbol lists when done reading
3377 the main symbol file?
3379 * symmisc.c (free_symtab): Free fullname field too.
3381 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
3382 (REGISTER_ADDR): Make result type unsigned int.
3384 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
3385 define REGEX must also define REGEX1 (its dependency).

3422 in raw hex as well as float format, regardless of whether it is
3423 a "virtual" convertible register.

3425 regs as a double, just in case it's being used that way.
3426 * values.c (unpack_long): Comment on array/function coercion.
3427 (unpack_double): Argument is in target byte order now. For
3428 integer arguments, just call unpack_long and float the result.

3430 * remote-nindy.c: Use ieee-float stuff.
3431 (nindy_fetch_registers): Unpack double regs to host double, then

3445 Changes from a bringup on the DEC Vax under Ultrix 4.0.
3447 * coredep.c (fetch_core_registers): Pass end-address of register

3498 * inftarg.c (child_detach): Pop the child_ops vector if the
3499 detach is successful.
3500 * remote-nindy.c (nindy_create_inferior): Don't push a new
3501 nindy_ops since nindy uses the same one for execution and memory
3503 * core.c (core_ops): Use child_attach and child_create_inferior
3504 rather than default attach and create_inferior functions.
3506 Handle floating point registers in core files.
3508 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
3509 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
3510 This version untested since BFD doesn't yet support sun3 core
3512 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
3513 conventions. Fix comments and style. This version has not
3514 been compiled yet, since we have no HP inhouse.
3515 * core.c (get_core_registers): Look for two sections, ".reg"
3516 and ".reg2", and pass both to fetch_core_registers sequentially.
3518 Revise directory path yet again.
3520 * source.c (forget_cached_source_info): Not static any more.
3521 (init_source_path): New default source path is "$cdir:$cwd".
3522 (dir_command): Handle variable arguments ($cdir, $cwd).
3523 (source_info): Print "Compilation directory" rather than
3524 "Originally compiled in" to remind people of $cdir.
3525 (openp): If the path contains $cwd, use current directory.
3526 (open_source_file): If compilation directory is known, replace
3527 first $cdir in path with the compilation directory.
3528 (print_source_lines): Even if we can't print the lines, set the
3529 current symtab and line for future commands like "info source" or
3530 "breakpoint". Also, error message now contains the file name,
3531 line number, and file access error message.
3532 (_initialize_source): Fix help text to describe changes.
3533 * main.c (cd_command): Forget cached source info when we chdir.

3539 Byte-swap COFF symbol tables if necessary when reading them in.
3540 Use complain() to replace error message in one spot. Needs
3541 corresponding change in bfd/coff-code.h to make some symbol
3542 swapping routines non-static.
3544 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)

3556 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
3558 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
3559 <rpc/rpc.h> and <rpc/types.h>.
3561 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
3563 * i960-tdep.c (examine_prologue): Add new argument limit,
3564 which stops the scan at the end of the prologue, or at the PC.
3565 This fixes a problem where it walks down into the code for the
3566 user's statements if that code looks like function prologues.
3567 Mark Fox and I have been bouncing this code back and forth, making
3568 small changes to it. Callers changed to match.
3570 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
3572 Cleanup for gdb-3.94 release final:
3574 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
3575 the .c files from vx-share and nindy-share, from the various
3576 macros, since they are not found via ALLDEPFILES.
3577 (SFILES): Add tm-i960.h.
3578 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
3579 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files

3586 * am29k-tdep.c: Add contribution line.
3587 (examine_prologue): Cache information about function prologues in
3588 the misc-function-vector to avoid lots of references over the
3589 serial line while examining instructions.
3591 * core.c (core_close): New function made from cleanup_core.
3593 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
3594 remote-vx.c, remote.c, target.c, target.h,
3595 Update target_ops vector to add attach, close, and load entries.
3596 Use add_syms_addr_command, not add_file_addr_command, for
3597 add_file. Break out close routine from existing code.
3599 * dbxread.c (really_free_pendings): Don't free pending_blocks;
3600 they are in an obstack.
3601 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
3603 (define_symbol): Add symbol type parameter; change callers;
3604 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
3605 it to influence the symbol class on the i960.
3606 (define_symbol): Swap LOC_CONST's into target byte order.
3608 * exec.c (exec_close): New function.
3609 (exec_file_command): Call it.
3611 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
3612 Fix byte order of frame pointer.
3613 (read_var_value): Result of 0 if var's value can't be found,
3614 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
3615 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
3616 (locate_var_value): Use read_var_value and use its lazy address
3617 as the location of the var's value. Lint.
3619 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
3622 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
3623 obsolete Intel versions in favor of vxgdb versions.
3624 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
3625 code dealing with byte order of values, which Intel did in host byte
3626 order rather than gdb-4's target byte order.
3627 (i960_frame_chain_valid): Move to nindy-tdep.c.
3628 (examine_prologue, skip_prologue, frame_find_saved_regs,
3629 frame_args_address, leafproc_return, saved_pc_after_call,
3630 pop_frame): Add vxgdb versions from Mark Fox.
3631 (examine_prologue, frame_struct_result_address): Add code
3632 to deal with the saved value of G13 (struct return address
3634 (frame_args_address): Modify Mark's version to prefer the
3635 saved value over the current value in the topmost frame.
3636 Cache result in the frame info to avoid performance hair in
3638 (print_fault): Add gdb960 code for printing faults.
3639 (_initialize_i960): Actually call check_host.
3641 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
3642 add stub routines. FIXME, these currently just return zero!

3645 (attach_command): Call target_attach, not target_open, now.
3647 * infrun.c (normal_stop): Make global, not static, for vx_attach.
3648 (child_attach): Rename from child_open.
3649 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
3650 don't confuse it with a zero step_resume_break_address.
3652 * inftarg.c (child_detach): Eliminate inferior_pid test.
3653 (child_files_info): Clean up message a bit.
3654 (child_ops): Use child_attach, not child_open, to attach.
3656 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
3657 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
3658 findvar.c to here, since it depends on the contents of the
3659 shadow_contents of breakpoints, but keep if #if 0 since it is
3662 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
3665 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
3666 (ptype_command, display_command): Eliminate have_inferior_p and
3667 have_core_file_p in favor of target_has_stack or
3668 target_has_execution.
3669 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
3670 code for actually finding the values of arguments, though we still
3671 keep track of the maximum stack offset for use in printing unnamed
3672 arguments. Handle missing FRAME_ARGS_ADDRESS.
3674 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
3675 (struct nindy_regs): Define registers passed to/from nindy.
3676 (nindy_fetch_registers, nindy_store-registers): Translate between
3677 nindy and GDB formats for the registers.
3678 (dcache_init): Statically allocate the cache, since it was being
3679 allocated by a malloc that was never freed anyway.
3680 (nindy_create_inferior): Error, not core dump, if no exec file.
3681 (nindy_before_main_loop): Use target_load, not target_add_file.
3683 * remote-vx.c (net_load): Specify large timeout for load
3684 requests. Allow user to break out with INTERRUPT.
3685 (net_break): Remove useless code, clean up. Change callers.
3686 (parse-args, skip_white_space, find_white_space): Clean up arg
3687 parsing to cope with quoted strings.
3688 (net_wait, net_quit): Never call error, just return status.
3689 (vx_read_register, vx_write_register): Cleanup status checking.
3690 #ifdef the code based on which CPU we are using (960 or 68k),
3691 FIXME, this should be completely general but it isn't yet.
3692 (vx_xfer_memory, vx_resume): Cleanup status checking.
3693 (vx_run_files_info): Improve message.
3694 (vx_load_command): Renamed from vx_add_file_command. Allow load
3696 (net_ptrace): Remove unused routine.
3697 (vx_wait): Adopt code from vxgdb960 to cope with broken
3698 connections to target machine and prompt to disconnect. Remove
3699 debug printouts. Map some EVENT_'s to SIGnals.
3700 (add_symbol_stub, vx_open): Print names of object files we found,
3701 and "ok" if we read their symbols OK. Clarify output in general.
3702 (vx_attach, vx_detach, vx_kill): Add these commands.
3703 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
3704 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
3705 "info files" output, and create_inferior, since we already have
3708 * stack.c (frame_info): Replace Frame_unknown with 0.
3709 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
3710 (return_command): Pop until the PC matches as well as the FP,
3711 so it works even if the FP is shared with another function,
3712 as in "frameless" or "leaf" procedures.
3714 * symfile.c (load_command): renamed from add_file_target_command.
3715 (add_syms_addr_command): renamed from add_file_addr_command.
3716 (add_syms_command): Stub to call target_add_syms.
3717 (_initialize_symfile): Change command names and descriptions,
3718 add-file => add-syms, and load from alias to its own command.
3720 * target.c (kill_or_be_killed, maybe_kill_then_attach,
3721 maybe_kill_then_create_inferior): Default for attempts to start
3722 a process, if one is already running, is to ask about killing
3723 it and retry if yes.
3724 (upstack_create_inferior): #if-0 it, strata obsolete it.
3725 (push_target, unpush_target, pop_target): to_close() a target
3726 before unstacking it.
3727 (target_info): Renamed from target_files_info.
3728 (_initialize_targets): Rename "i files" as "i target", accessible
3731 * target.h: Improve comments about the target_ vectored routines.
3733 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.

3736 (SKIP_PROLOGUE): No longer a no-op.
3737 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
3738 (*_REGNUM): Sort register numbers.
3739 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
3740 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
3741 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
3742 are now 10 byte extendeds, not 8 byte doubles.
3743 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
3744 for nindy versus vxworks targets. FIXME, this should possibly go
3745 in the target vector.
3746 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
3747 frame_saved_regs and arg pointer with each frame.
3748 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
3749 (FRAME_ARGS_ADDRESS): Use cached result.
3750 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
3751 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
3752 (PRINT_RAMDON_SIGNAL): Call print_fault.
3753 (POP_FRAME): Now works.
3755 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
3756 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
3757 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
3758 (ADDITIONAL_OPTION_HANDLER): use target_load, not
3761 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
3762 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
3764 * valarith.c (value_subscripted_rvalue): Avoid handling
3765 floats and doubles specially; it gave alignment errors. Lint.
3767 * valops.c (value_of_variable, value_of_this): Error if unknown
3770 * valprint.c (print_floating): Bcopy rather than pointer-deref,
3771 to avoid alignment problems.

3774 (val_print): Use unpack_long rather than pointer-deref.
3777 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
3778 to avoid alignment problems.
3779 (value_being_returned): Error if return value unknown.
3780 (set_return_value): Add bogosity warning, FIXME. *
3782 * TODO: A woman's work is never done.
3784 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
3785 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
3786 Add ieee-float.o to OBS.
3787 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
3788 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
3789 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
3791 Changes to generalize the VxWorks RPC protocol slightly, to handle
3792 i960 as well as 68000.
3794 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
3795 * vx-share/reg.h: Produce i960 regs #ifdef I80960
3796 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
3797 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
3798 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
3799 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
3800 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
3801 so they will move in target byte order rather than network
3802 byte order (happens to be the same).
3804 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
3806 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
3808 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
3811 Add contribution lines to various files, showing where they
3814 * breakpoint.c (break_insn, check_break_insn_size,
3815 read_memory_nobpt): Remove to mem-break.c.
3817 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
3820 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
3821 entry has bad register number. This change is not
3822 tested in this release, FIXME.
3824 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
3827 * value.h: Force value's contents field to be aligned to hold
3828 at least a double or a long long (if supported). This avoids
3829 doing bcopy's in and out of the contents field.
3831 (step_1): Avoid coredump under obscure circumstances when we
3834 * symtab.h (misc_info): Add field to misc function vector for
3835 any kind of cached information the target code desires. AMD
3836 29000 uses this to avoid repeating examine_function_prologue's.
3838 * coffread.c: Lint. Remove static symfile, read_section_header.
3839 core.c (have_core_file_p): Lint: remove.
3840 expprint.c (print_subexp): Lint.
3841 infptrace.c, valops.c, valprint.c: lint.
3843 Roll in changes from vxgdb-5.0.1:
3845 * symtab.h: Comment byte order of each address class. Add
3846 LOC_LOCAL_ARG for frame-relative args (960).
3847 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
3848 symtab.c, symmisc.c: ditto.
3850 * infrun.c (init_wait_for_inferior): Clear stop_signal.
3852 * remote.c (remote_resume): Error if resume with a signal.
3854 * symfile.c (prim_record_misc_function): Clear misc_info.
3855 (fill_in_vptr_fieldno): Check stub type of arg.
3857 * valops.c (value_cast): Avoid looking up names of types whose
3858 name we don't know, to prevent coredump. Sun CC produces typedef
3859 rtx and the name of *rtx is zero...
3861 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3863 Roll in changes from final AMD 29000 port (Tiemann).
3865 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
3866 for ../include/a.out.encap.h. This might not work now that BFD
3867 is separately compiled. Instead, BFD support for encap will have
3868 to translate machine type 29k into the right COFF_MAGIC.
3870 * infcmd.c: Remove references to inferior_pid that aren't used
3871 in actual ptrace calls; use target_has_execution, etc.
3872 (have_inferior_p): Remove function.
3873 (program_info): Print target info rather than "process number";
3874 avoid gratuitous messages unless from_tty.
3875 (run_stack_dummy, finish_command): Set proceed_to_finish.
3876 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
3877 main.c: Lint. Lose have_inferior_p().
3878 inferior.h (have_inferior_p): Remove, lint.
3879 (proceed_to_finish): Add flag to ask that all regs be saved
3880 by normal_stop, for the few commands that need it, speeding up
3881 serial I/O. Add comments to stop_registers.
3883 * remote-eb.c: Remove newline from breakpoint message we grep
3884 for. Never time out when running the user program.
3888 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3890 Roll in changes from vxgdb-5.0.1:
3892 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
3893 symbol in its raw form, we are processing an unlinked ".o" file.
3894 See if the target environment has assigned it an address, using
3895 target_lookup_symbol (VxWorks does), and enter it into the symtab
3898 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
3899 68k versions for a simpler version that assumes zero FP at bottom.
3900 Fixes bug of truncated stack reports.
3902 * target.h (target_lookup_symbol): Define this routine's args
3903 and result, finally.
3905 * target.c (nosymbol): Default routine for target_lookup_symbol.
3906 (target_default): Default lookup_symbol and call_function too.
3907 (files_info): Only print has_all_memory warning if a non-dummy
3910 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
3911 vx_convert_from_virtual): If target does not have floating point,
3912 zero register "values", and avoid doing cross-net conversions.
3913 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
3914 (vx_open): Rearrange code that attaches to target and reads
3915 symbols for all loaded modules, to work if some of the modules
3916 are not accessible. Add symbol_stub() and add_symbol_stub()
3917 as callbacks from catch_errors(). Allow connect attempt to be
3918 interrupted painlessly with ^C (FIXME, there are still some bugs
3919 if the interrupt happens during symbol reading.). Print
3920 final message with puts_filtered, since symbol messages are
3925 * main.c (catch_errors): Only print errstring if non-null.
3926 (command_loop): Avoid an ioctl per command to test ISATTY.
3928 * remote-vx.c (net_load): make static; avoid sophomoric msg.
3929 (vx_xfer_memory): Return correct result!
3930 (vx_files_info): Indicate whether target has float or not.
3931 (vx_lookup_symbol): Complain, not error, if target gone.
3932 (vx_open): Print "Connected" msg before disabling immediate-quit.
3933 [FIXME: lookup_symbol and vx_open changes need testing.]
3935 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
3936 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
3937 contributor lines and update copyrights to 1991.
3939 Changes from an attempted H-PUX host port:
3941 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
3942 defines PT_ATTACH and PT_DETACH but not PT_KILL.
3943 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
3944 * remote-vx.c: include <sys/time.h> for HPUX.
3945 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
3946 "core_file_command" routine to BFD regime. May not work yet.
3948 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
3950 * xgdb.c: Replace X10 version with some VJ version.
3951 (FIXME: Its copyright assignment is not on record.)
3952 * xgdb.c: Update include files to X11R4 (Xaw crud).
3953 (xgdb_display_source, create_text_widget): fix call to
3954 get_filename_and_charpos. Rewack source window stuff for X11R4
3955 (gleaned from include files, and "nm's" of binary libraries, since
3956 I had no doc available).
3957 (append_selection, append_selection_word): Disable with FIXME
3958 since R4 changed interface here.
3959 (create_buttons): Add back the old set of buttons.
3960 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
3962 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
3963 Roll VERSION to 3.94 (not yet final though).
3965 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3967 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
3968 obstack_int_grow, obstack_int_grow_fast): Eliminate
3969 cast on left of assignment, which gives MIPS cc fits and is
3972 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
3973 F_ALIAS. Use printf, not fprintf, when not passing a file
3975 (compare_opcodes): Check that identical instructions have
3976 identical opcodes, complain otherwise.
3978 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
3979 was reported by Roland McGrath.
3980 (unimp): Only match if exactly zero instruction. (Roland)
3981 (branches and traps): Generate all variations of these
3982 instructions with macros, based on a single call that defines
3983 each condition name and its binary representation.
3984 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
3986 * valprint.c (val_print_fields): Take, and use, format parameter.
3987 This means that "p/x struct" again prints the elements in the
3988 desired format. Changed callers.
3990 * stack.c (frame_info): Use filtered output, and indicate wrap
3991 points. Remove kludgy formatting designed to avoid line wrap.
3993 * utils.c (wrap_here): If the line is already full (because
3994 we had printed a long indent or long wrapped string), do an
3995 immediate newline-and-indent.
3997 * m68k-pinsn.c (print_insn_arg): Bugfix from
3998 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
3999 instruction is incorrectly disassembled as bkpt #8.
4001 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
4002 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
4003 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
4004 and then will dump core (sometimes). I traced it back to an
4005 uninitialized symfile_name in psymtab_to_symtab.
4006 (const_vol_complaint): Add quotes to message.
4007 (define_symbol): Only believe line number if gcc_compiled.
4008 Avoid allocating symbol if we will not return it.
4010 Add target strata support so that newly established targets go
4011 into their right place in the target stack (e.g. a new exec file
4012 doesn't wipe out the ability to access the running process).
4014 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
4015 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
4016 and initialize it properly in all the targets.
4018 * target.h: Document strata. Change return type of push_target.
4020 * target.c (nomemory): new function for dummy memory access.
4021 (tcomplain): Rename complain, now also used in symfile.c.
4022 (push_target): Push targets within strata. New return value shows
4023 whether new target is on top of stack or not. Always keep dummy
4025 (target_files_info): Ignore dummy target.
4027 * core.c (core_open): Warn user, and skip accessing file, if the
4028 core target is not the topmost target in the stack.
4029 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
4032 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
4033 target_ops, it doesn't belong there since we have no regs there.
4034 Change name of target from machine => memory to clarify.
4036 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
4038 * Freeze version 3.93 for release.
4040 * Makefile.dist: Handle vx-share and nindy-share subdirs
4041 properly when building gdb.tar.Z.
4043 * symtab.c: lint; add no_symtab_msg to consolidate the messages
4044 printed in various places, so I could change just one copy.
4046 * dbxread.c, coffread.c: Change references to bfd->iostream
4047 to cast to FILE *, now that BFD avoids needing types defined
4048 in other header files.
4050 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
4052 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
4053 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
4054 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
4055 (actually gcc -Wall).
4057 * dbxread.c: Remove first_global_sym, last_global_sym, since
4058 they are never referenced.
4060 * defs.h (baud_rate): Declare.
4061 main.c: Define it, and add the -b option to set it.
4063 * gdb-int.texinfo: Add text on how to define a new host or target
4064 architecture, prompted by Per Bothner's questions about MIPS
4067 * gdb.texinfo: Document "complaints". Change doc of -q since
4068 gdb no longer prints the copyright and blurb if you specify a file
4069 name to be debugged (just like Emacs). Add doc for Nindy-specific
4070 command line flags for specifying target serial port and such.
4071 Update copyright to 1991.
4073 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
4074 has taken over for us the job of ripping up executable files. The
4075 crud caused Per Bothner's port to not compile.
4077 * infrun.c (normal_stop): Avoid printing "Program exited
4078 normally" if we are in batch mode. This allows a GDB which
4079 executes a program on a target system, to behave like a Unix
4080 command (input from stdin, output to stdout, no extraneous
4083 * main.c (main): Allow additional machine-dependent command line
4084 options to be specified with the ADDITIONAL_OPTIONS,
4085 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
4086 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
4087 processing to occur just before the main loop with
4088 BEFORE_MAIN_LOOP_HOOK.
4089 (main): If a "core file" argument is specified, and it is not a
4090 core file, try it as a process ID to attach.
4091 (symbol_completion_function): Attempt to cope with
4092 "show screen-" TAB, not very successfully. This needs more work,
4094 (batch_file): New function, returns whether we are reading
4095 commands from an interactive tty on stdin, or from somewhere else.
4096 Called by normal_stop since it doesn't get from_tty passed down
4097 to it like many commands do.
4099 * remote-nindy.c: Handle command line options for nindy
4101 (nindy_before_main_loop): Prompt user for tty name if they
4102 don't specify it before getting to the interactive command loop.
4104 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
4105 and -r command line options. Also add hook before main loop
4106 to make it easy to specify a tty.
4108 * TODO: More things to do, one done.
4110 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
4112 * dbxread.c: Make complaint() calls pass pointer, not struct.
4113 Add complaints about badly formatted C++ type information
4114 (const/volatile indicator, and parse errors resulting in
4115 error_type). Fix C++ virtual member fn comment.
4116 (read_struct_type): Avoid bumping pointer if we got a parse
4117 error; this prevents our walking beyond the end of a string.
4118 Terminate loop on null char as well as semicolon.
4119 (process_one_symbol): Fix the LBRAC fix so that it uses the
4120 last previous SLINE, FUN, or SO record's PC address. C++ debug
4121 symbols did not have SLINE records in a useful order compared
4122 to the LBRAC records.
4123 (define_symbol): Handle "catch" records.
4125 * symtab.c (check_stub_type): Added new complain
4126 `stub_noname_complain' and added a consistency check to
4127 keep the debugger from crashing when finishing from an
4128 exception frame. A real fix will be needed later.
4130 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
4132 * infcmd.c (attach_command): Make global.
4134 * Makefile.dist (REMOTE_OBS): Make these compile by default,
4135 but make them easy to comment out. Perhaps later they should
4136 be enabled by what CPU you configure for? FIXME.
4137 (VERSION): Roll to 3.93.
4138 (pinsn.o): Remove rule for obsolete file.
4139 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
4141 Run down a problem that manifested by printing the wrong function
4142 name in stack traces of read_ofile_symtab. Turned out that the
4143 problem was the SunOS 4.1.1 (and previous) C compiler outputs
4144 the LBRAC symbol with an address in the *data* segment, which
4145 blew our binary search through the blocks.
4147 * dbxread.c: Use the complain() facility consistently to bitch
4148 about problems in the symbol file we are reading.
4149 (finish_block): Add code to check the nesting of the blocks;
4150 complain and Procrust them to fit if wrong.
4151 (make_blockvector): Check the order of the blocks, complain
4152 [but don't cope] if wrong.
4153 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
4154 symbols to be sure their PC value is greater than the last SLINE
4155 (line number) symbol we've seen, complaining and adopting the
4156 SLINE PC value if wrong.
4158 * symfile.h (struct complaint, complaint_root, complain,
4159 clear_complaints): Add.
4160 * symfile.c (complain, complaint_root, clear_complaints): Add
4161 facility to deal with non-fatal complaints and to regularize their
4163 (symbol_file_add): Clear complaint counters to allow new complaints.
4164 (initialize_symfile): Add 'set complaints' and 'show complaints'.
4166 * dbxread.c (dbx_symfile_read): Remember the address and size
4167 of the string table for the main symbol file, so we won't read it
4169 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
4170 to avoid reading the string table yet again. Lint.
4171 (throughout): Improve filtered output, including word wrap.
4172 (read_range_type): Improve Bothner's fix to handle other types too.
4174 * utils.c: Improve line wrap implementation. Handle unlimited
4175 width by making chars_per_line unsigned.
4176 (puts_filtered): New, easy, function.
4178 * defs.h (puts_filtered): add.
4180 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
4181 call the identical sort_symtab_syms() in symfile.c instead.
4183 * expread.y: Suggest the `file' command rather than `symbol-file'.
4185 * command.h (enum var_types): Add zinteger for seroable
4187 * command.c (do_setshow_command): Handle var_zinteger. Restructure
4188 nested if's into a switch.
4190 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
4191 we did not stop because of a breakpoint (it must have been for
4192 some other reason, like a "stepi"), so don't print anything.
4194 * symtab.c: Include <sys/types.h> all the time. Now that BFD
4195 doesn't include <sys/types.h>, old SunOS's require it for
4198 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
4200 A test port of gdb-3.92.6 to the Sony NEWS.
4203 Don't normally link in remote- or vx stuff.
4204 Some of it doesn't compile, and it wastes space for 99% of the users.
4205 Remove reference to no-longer-used HAVE_VPRINTF.
4206 Fixed BFD_DEP typo to BFD_DIR.
4208 Fix cast in arg to bfd_h_getlong.
4209 Make char *prefix be const.
4210 Fix how certain range types are mapped into builtin unsigned int types.
4212 Remove 2 #includes. They cause errors (on Sony, at least),
4213 and aren't needed (they wern't in earlier versions).
4215 print_address_symbolic should never demangle labels
4216 (since it prints *assembler-level* labels).
4218 [This was superseded by the change to printcmd below.]
4221 Add some "volatile" return types to avoid warnings.
4222 If MISSING_VPRINTF add vprintf function and not just macro
4223 (since vprintf is used in printcmd.c).
4225 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
4226 (The latter isn't grokked by some PCC-based compilers.)
4228 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
4230 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
4231 * nindy-share/coffstrip.c
4232 Added some forward declarations (otherwise, gcc complains
4233 about implicit extern redefined as static).
4235 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
4237 Changes inspired by Per Bothner:
4238 * printcmd.c (print_address_symbolic): Take additional parameter
4239 specifying whether to demangle.
4240 (print_address): Pass in asm_demangle to control demangling.
4241 (print_address_demangle): New fn, takes explicit arg to control
4243 * utils.c: Add new vars demangle and asm_demangle, and let them
4245 (fputs_demangled): If !demangle, just print the argument.
4246 (fprint_symbol): If !demangle, just print raw symbol.
4247 * valprint.c (val_print): Call print_address_demangle rather than
4248 print_address, to cause demangling to depend on the global
4249 rather than assembler-level demangling setting.
4250 * WHATS.NEW, gdb.texinfo: Document.
4252 * main.c (show_command): Show all settings if no arg.
4253 (initialize_main): Make "info set" the same as naked "show".
4254 * command.c (cmd_show_list): Handle prefix commands in the
4255 list, and print the name of the setting as well as its English
4256 description and value.
4258 Allow gdb functions to specify where a line should wrap if it
4259 exceeds the size of a terminal line. Use it to make the output
4261 * utils.c (set_screen_width_command): New fn, mallocs a buffer
4262 of the right size when screen width changes.
4263 (set_screensize_command, screensize_info): Remove #if 0'd fns.
4264 (wrap_here): New fn, indicates a point in the output where we
4265 should wrap the line rather than just letting it overflow at a
4267 (fputs_filtered): Implement wrapping.
4268 (n_spaces): New fn, returns a pointer to N spaces.
4269 (print_spaces_filtered): Use n_spaces.
4270 * defs.h (n_spaces): Declare.
4271 * stack.c (print_frame_info): Wrap with 4-space indent after
4272 fn name and before filename and line number.
4273 * printcmd.c (print_frame_args): Wrap with 4-space indent
4274 before each argument name is printed.
4275 * valprint.c (value_print): Wrap with no indentation before
4277 (val_print_fields): Wrap with indentation relative to nesting
4278 level before each field name.
4279 (val_print): Wrap with nesting indentation before array elements.
4280 * command.c (do_setshow_command): Avoid extra newlines,
4281 wrap with 4-space indent around values printed, end with period.
4282 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
4284 * breakpoint.c (breakpoint_1): Implement addressprint for
4285 "info breakpoints" display. Change file name and line number
4286 format to " at file:nnn" rather than " (file line nnn)".
4287 * gdb.texinfo: Document.
4290 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4292 Frozen for gdb-3.92.6 release.
4294 README, WHATS.NEW: Update for 3.92.6 release.
4296 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
4297 coffread.o from configs since it is now built by default.
4298 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
4299 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
4300 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
4301 from configs since it is now built by default.
4303 Makefile.dist: Update for release 3.92.6. Handle files that
4304 have been moved to ../include, ../getopt, or ../bfd. Add
4305 saber.suppress and tests directory. Add config.status to
4306 the release (it will say "none").
4308 coredep.c: Minor formatting fixes.
4310 These changes were made in early December but only checked in now:
4311 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
4312 nindy-share/nindy.c: lint
4313 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
4314 register values coming back from the target; we store values
4315 in target byte order everywhere.
4317 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
4319 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
4321 * valprint.c (cplus_val_print, val_print_fields): New functions,
4322 which print C++ objects. They conspire to avoid printing a
4323 virtual base class more than once, following all the twists and
4324 turns of C++ virtual base rules.
4325 (val_print): Call the above rather than do it by hand.
4327 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
4328 symbol file, not for added files like shared libs. This really
4329 needs to be generalized to a timestamp per file.
4331 * core.c (cleanup_core): Avoid coredump if no core file.
4333 * config.gdb: Accept -host or -target in place of +host or
4336 * coffread.c (find_linenos): Avoid desupported BFD interface
4337 to line numbers. We still read them manually rather than using
4338 BFD's "generic" features.
4340 * gdbrc.tex, threecol.tex: Add GDB reference card and its
4342 Makefile.dist: Add refcard to OTHERS list for creating tar files.
4344 * Makefile.dist: Eliminate use of $< in explicit targets.
4346 * readline/Makefile: Use $< rather than $*.c, which does not
4347 include the VPATH in GNU Make.
4349 * tconfig/i960-bout, tconfig/i960-coff: These are identical
4350 copies of tconfig/i960, added for global configuration
4351 compatability. All i960 versions can read both coff and b.out.
4353 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
4354 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
4357 * TODO: Think of more things to do.
4359 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
4361 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
4362 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
4363 64-bit float conversion.
4365 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
4366 equivalent to sun?os4 so global config works.
4368 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
4370 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
4372 * main.c: Only declare linesize once; declare pagesize not at
4373 all, since it is never used.
4374 (main): Clear newly allocated line before it is used.
4376 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
4378 Further stabilization for the Intel 960.
4380 * Makefile.dist: Parameterize the location of the "include"
4381 and "bfd" directories, as well as "getopt". Add symfile.c.
4382 Link in both dbxread and coffread. Fix up "make depend" to
4383 rewack the locations of include, bfd, and getopt in its output.
4385 * README: Document moving include files, improve some of
4388 * coffread.c: Move common code out to symfile.c. Change
4389 symbol_file_command style interface to use new *_symfile_init
4390 and *_symfile_read interface under BFD. Use BFD internal
4391 info to locate line table, symbols, etc.
4393 * core.c (core_fetch_registers): Rename to get_core_registers
4394 to avoid confusion with fetch_core_registers.
4395 (register_addr): Move to coredep.c, which is already machine
4396 dependent. This leaves core.c pretty clean of dependencies.
4398 * coredep.c (register_addr): Accept this routine from core.c.
4400 * dbxread.c: Move common code (with coffread.c, etc) into new
4401 symfile.c. Each psymtab now contains a pointer to the
4402 format-dependent function that knows how to read it in. Make
4404 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
4405 (process_one_symbol): Add code to complain about a "compiler bug
4406 we muzzle here", if we actually see it.
4408 * eval.c (evaluate_subexp): Insert missing "break" statements
4409 in code that determines whether a variable is an lvalue in
4410 memory, register, or whatever. I detected this via a compiler
4411 bug in which it *almost* mashed out the whole switch statement.
4413 * gdb-int.texinfo: Add minor sections on configuring gdb for
4414 release, and about the README file.
4416 * infcmd.c (registers_info): Fix formatting somewhat. Still
4417 not as pretty as before, but it handles byte swapping.
4419 * remote-nindy.c: If data cache routines are interrupted while
4420 waiting for the remote end, be sure that any uninitialized cache
4421 blocks are on the free list, not on the valid list!
4423 * symfile.h: Flesh out this header file with all the various
4424 routines and variables that have been merged in from dbxread.c
4425 coffread.c, and symtab.c to symfile.c.
4427 * symfile.c: New file, containing code common to dbxread.c,
4428 coffread.c, and some code from symtab.c. All generic code for
4429 reading symbol files should be in here now.
4430 (unrecord_misc_function): Remove unused function.
4432 * symtab.h: Remove file-reading things to symfile.h.
4434 * symtab.c: Remove file-reading things to symfile.c.
4436 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
4437 to decode i960 fault types.
4439 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
4440 target.c: Change type of the "resume" function from int to void,
4441 since its result was never used.
4443 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
4445 * main.c: Replace "stupid" with "caution"; you now "set caution
4448 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
4450 * infcmd.c (do_registers_info): Call val_print to deal with the
4451 byte order of the registers being printed. FIXME, this makes
4452 the formatting of the output uglier.
4454 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
4455 defined, call it for signals the debugger doesn't itself use.
4456 The i960 uses this for more detailed fault information.
4458 * remote.c (remote_open): If arg is null, print help rather than
4461 * sparc-xdep.c (register_valid): Avoid declaring size, since
4462 various modules will think of various sizes depending on the
4463 architecture of their tm-file. FIXME, we need protection against
4464 actually entering one of those modules, which would clobber
4465 storage if not for the target architecture compiled into gdb.
4467 * stack.c (up_command, down_command): Always print the frame
4469 (up_silently_command, down_silently_command): New commands
4472 * i960-pinsn.c (reg), i960-tdep.c: Lint.
4474 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
4475 more parameters than it used to.
4477 * findvar.c (registers): Increase slop to 256 bytes, which should
4478 protect us against even most RISC machines with large register
4480 (locate_var_value): Move declaration inside related ifdef.
4482 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
4483 throughout, to avoid throwing away buffered input from the board.
4484 (nindy_wait): Supply_register takes addr_of_value, not value.
4485 (i960_print_fault): Renamed from i80960_fault.
4486 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
4487 (nindy_store_registers): Avoid regs_changed stuff, just stuff
4489 (nindy_create_inferior): Don't bother to write PC_REGNUM since
4490 we can set the PC in the call to proceed(). Unpush nindy_ops
4491 before pushing it on top, to avoid message to user. Eliminate
4492 commentary from Unix machines that just misleads here.
4493 (reset_command): Fix error message to suggest target command.
4495 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
4497 Release 3.92.5 as frozen.
4499 Stabilize the merged release...with help from lint, Saber C,
4502 Everywhere: Add include files needed to declare return types
4503 of functions called.
4505 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
4507 * breakpoint.h: Add undeclared breakpoint functions, and some
4508 functions for display handling since I couldn't think of a better
4511 * breakpoint.c (insert_breakpoints): Make code for disabling
4512 shared library bkpts more likely to work. It's used when we
4513 rerun a program and stop before the shared library has been
4515 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
4516 cast from pointer, so it squeezes through catch_errors.
4517 (bpstat_stop_status): Fix logic broken some time ago. We now
4518 always create a bpstat if the stop address matches a breakpoint,
4519 even if we don't stop there -- just like the old code used to do
4520 before I got my fingers into it (sigh).
4521 (breakpoint_1): Print "ignore count" after "stop only if"
4522 condition, since that's how it actually works.
4523 (mention): Handle watchpoints as well as breakpoints.
4524 (watch_command): use set_raw_breakpoint and mention to do most
4525 of the work (and initialize all the fields!). Only pass one
4526 arg to parse_c_expression, since that's all it takes.
4528 * command.c (not_just_help_class_command): Rename arg to args
4529 since we ignore "unused argument" warnings on vars named "args".
4530 inflow.c (child_terminal_info): ditto.
4531 infptrace.c (kill_inferior): ditto
4532 main.c (catch_errors, version_info, quit_command, pwd_command,
4533 source_command, dump_me_command, editing_info,
4534 set_history_size_command, set_history, show_history,
4536 stack.c (locals_info): ditto
4537 target.c (target_files_info): ditto
4538 valprint.c (set_input_radix, set_output_radix): ditto
4540 * core.c: Remove old variables for handling core and exec file
4541 sections (data_start, data_end, stack_start, stack_end,
4542 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
4543 text_end, exec_data_start, exec_data_end, text_offset,
4544 exec_data_offset, data_offset, stack_offset). They're
4545 superseded the more general build_section_table and
4547 (get_exec_file): Mention the `file' command.
4548 (read_memory_check): Rename to memory_error, and only call it
4549 in the case of an actual error.
4550 (read_memory, write_memory): call memory_error.
4551 (core_fetch_registers): Register section name is ".reg".
4553 coredep.c: Remove a bunch of crud now that all this file does
4554 is pull the registers out of a core file.
4555 (fetch_core_registers): Rewrite to actually work, I hope.
4557 dbxread.c: Use a.out.gnu.h, not system a.out, now.
4558 Replace index() with strchr(). Remove all the pre-BFD macro
4559 definitions for accessing the symbol file.
4560 (struct dbx_symfile_info): Encapsulate the information that
4561 dbx_symfile_init needs to pass to dbx_symfile_read in this
4564 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
4565 dbx_symfile_discard): Rearrange symbol file reading to divide
4566 the format-specific part from the format-independent part,
4567 leaving the format-independent part such as file name expansion
4568 and opening in symtab.c. This replaces
4569 partial_symbol_file_open and partial_symbol_file_read.
4570 Symbol_file_read, add_file, add_file_target_command,
4571 add_file_addr_command move to symtab.c. Pass an explicit
4572 "mainline" flag for when reading the main symbol table, rather
4573 than relying on the offset address to be zero or nonzero.
4575 (dbx_symfile_read): Don't allow void *'s to be printed as
4577 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
4578 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
4579 macro" debug version really work.
4580 (read_dbx_symtab): Remove unref'd parameter inclink.
4581 Avoid swapping N_SLINE symbols, for speed.
4582 Merge N_TEXT!N_EXT case with the other external symbol
4583 definitions' case. Add comments.
4584 (start_psymtab): Allocate the symfile name in the psymtab on
4585 the psymbol_obstack, rather than using the caller's storage.
4586 (end_psymtab): Only allocate a dependencies list if there are
4588 (psymtab_to_symtab_2): Use BFD when reopening file to read
4589 its symbols for real.
4590 (read_struct_type): Add FIXME comments where it needs work
4592 (read_huge_number): Add FIXME about overflows.
4593 (read_range_type): Add FIXME about comparing a long to 1<<32.
4595 * coffread.c: Minor changes to move things closer to the new
4596 regime with symtab.c and dbxread.c Major work is still needed
4599 * exec.c (exec_file_command): Remove old variables (see core.c
4601 (xfer_memory): If memory transfer is right at the end of a
4602 section, don't lose.
4604 * findvar.c (get_saved_register): If value is in a real
4605 register, LVAL is lval_register, not lval_memory.
4607 frame.h: Declare print_sel_frame and record_selected_frame.
4609 gdb-int.texinfo: New file, for GDB internals documentation.
4610 Very simple, unformatted doc of cleanups is there for now.
4612 gdbcore.h: Remove obsolete variables that described a.out
4613 section addresses and offsets. (See core.c above.)
4614 Declare fetch_core_registers and registers_fetched.
4616 getopt.c: Declare char *alloca(); even on SPARC.
4618 infcmd.c (run_command): Call target_kill rather than
4620 (step_command, next_command, stepi_command, nexti_command):
4621 Declare from_tty parameter even though we don't use it.
4622 (run_stack_dummy): argument BUFFER is a char array, not
4623 a pointer to REGISTER_TYPE.
4624 (finish_command): using_struct_return needed a value *,
4625 not a struct symbol *.
4627 * infptrace.c (child_xfer_memory): To avoid dependency on
4628 where sections are in memory, try PT_WRITE_D and if that fails,
4629 try PT_WRITE_I. Most Unixes don't care which you use.
4631 * infrun.c (step_resume_break_shadow): Change to array to
4632 match other breakpoint shadow storage.
4633 (clear_proceed_status): Pass address of bpstat to
4634 bpstat_clear, not the bpstat itself.
4635 (child_create_inferior): FIXME comment about if the child
4637 (start_inferior): Remove old function.
4638 (child_open): Use target_kill rather than kill_inferior.
4639 (wait_for_inferior): Ditto.
4640 (insert_step_breakpoint, remote_step_breakpoint): Use
4641 new step_resume_break_shadow.
4643 * inftarg.c (child_wait): If all child processes die,
4644 pretend that the one being waited for exited with signal 42.
4646 * main.c (command_line_input): When scanning for comments,
4647 don't coredump on unclosed quotes.
4648 (quit_command): Use target_kill rther than kill_inferior.
4649 (_initialize_main): Rename class_user from "user" to
4652 * printcmd.c (print_command_1): Initialize "fmt" if no format
4653 is specified by the user.
4654 (print_frame_args): Only add to args_printed if we are
4655 actually fetching args from the stack (avoiding undefined
4657 (_initialize_printcmd): Remove bogus \{ from string.
4659 * remote-eb.c (eb_open): Avoid coredump on no argument.
4661 * remote-nindy.c: Bring out of Intel environment into new
4662 target environment. Remove all conditional compilation on
4663 I80960. Massive hacking throughout.
4664 (nindy_xfer_inferior_memory): New routine stolen from
4666 (nindy_create_inferior): New routine pieced together, probably
4667 not quite working yet.
4668 (nindy_ops): New target_ops struct for nindy.
4670 * remote-vx.c: Use write_memory rather than target_write_memory
4671 to get error checking.
4672 (vx_add_file_command, vx_open): Use symbol_file_add rather than
4674 (vx_create_inferior): Use target_terminal_ours...
4676 * signame.c (_initialize_signame): Always initialize, since
4677 we need the table for things other than psignal.
4679 * solib.c (solib_add): Use symbol_file_add, not add_file.
4680 (solib_address): Return boolean result rather than struct
4681 pointer which nobody else knows the type of.
4683 * sparc-tdep.c, valops.c: Use write_memory rather than
4684 target_write_memory, to get error checking.
4686 * stack.c (locals_info, catch_info, args_info,
4687 get_selected_block, frame_command, up_command): Use
4688 target_has_stack, rather than have_inferior_p or
4691 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
4693 * symfile.h: New file, defining the interface between the
4694 generic and object-file-specific symbol reading code.
4696 * symtab.c: Move generic symbol-reading interface to symtab.c,
4697 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
4698 table to map BFD targets to symbol-reading modules in GDB.
4699 Change index to strchr.
4700 (lookup_struct_elt_type): Use error() rather than hand-made
4701 simulations thereof.
4702 (lookup_partial_symbol): Speedup slightly when length == 0.
4703 (symbol_file_add): New function.
4704 (symbol_file_command): Call it.
4705 (symfile_open, symfile_init): New function.
4706 (add_file_target_command, add_file_addr_command): moved from
4709 * target.c (target_command): use target_kill.
4711 * target.h (target_files_info): Don't declare, never called
4714 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
4715 files to determine stack end address.
4717 * valarith.c (value_x_binop, value_x_unop): Change error message
4718 to be more useful. Pass proper argument to value_struct_elt.
4720 * valops.c (value_assign): FIXME comment that long long
4721 bitfields will break here.
4723 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
4724 Update `make saber_gdb' to work better.
4726 * TODO: A woman's work is never done.
4728 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
4729 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
4730 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
4731 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
4732 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
4733 valops.c, valprint.c, exec.c: Lint.
4736 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
4738 Continuing Intel 960 port merge of GDB.
4740 * Makefile.dist: Merge i960 "nindy-share" files. Rename
4741 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
4742 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
4743 Wack over "make depend" so it handles files in subdirectories
4744 vx-share, nindy-share, bfd, and in the current directory.
4746 * blockframe.c (get_prev_frame_info): Remove fatal error
4747 if stack not defined.
4749 * core.c (core_open, core_detach): New functions that handle
4750 the old "core-file" command as "target core" and "detach" instead.
4751 (core_file_command): Call them.
4752 (core_xfer_memory): Use common routine xfer_memory.
4754 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
4755 dbxread now uses bfd for everything but symbol reading itself.
4756 BFD internals are used to drag out the relevant file offsets.
4757 (partial_symbol_file_open): Change args all around for BFD.
4759 * symtab.c: Rename "value" to "val" everywhere, so we can
4761 (symbol_file_command): New command, moved from dbxread.c
4762 and coffread.c. It uses BFD to read the file, then vectors
4763 based on its type, to dbx or coff symbol readers.
4764 * symtab.h: Extern a few vars for symbol_file_command.
4766 * target.h: Breakpoint takes a char * save area, not a char **.
4768 * valprint.c (val_print): When unpacking bitfields, offset
4769 the address in gdb of the value, if it is declared with a shorter
4770 type. Remove the last "runtime kludge test" of host byte order.
4772 * utils.c: Remove old my_bfd_read routine.
4774 * stack.c (frame_info): Use target_has_stack. Print program counter
4775 register's actual name rather than "pc", since it's called the
4776 "ip" (instruction pointer) on the i960 (sigh).
4778 * target.c (target_command): Add command for selecting a target
4779 type and calling its open routine. This is used for initiating
4780 communication with a particular target, in a generic way.
4782 * tm-i960.h: Update for modern gdb. Remove semicolons from
4783 various macros. Handle reading struct return convention, and
4784 error-out attempts to return structs with the "return" command.
4785 Be sure gdb doesn't think we know how to call functions in the
4788 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
4789 to i960_xxx in lower case.
4790 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
4791 not being defined yet.
4793 * remote.c (remote_open): Call start_remote to initialize
4794 wait_for_inferior during open.
4795 (remote_xfer_inferior_memory): Return length written rather
4798 * remote-vx.c (target_command -> vx_open): Use new generic
4800 * remote-eb.c, inftarg.c, exec.c: ditto.
4802 * infrun.c: Fix comments.
4803 (attach_program -> child_open): Use new generic target command.
4804 (wait_for_inferior): Clear saved register values before target_wait,
4805 so target_wait can set some of them if convenient.
4807 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
4808 Return success indicator, not void.
4809 (child_xfer_memory): Avoid fetching initial word if we'll
4810 overwrite it anyway.
4812 * infcmd.c (attach_command): Use new generic target open routine.
4813 (_initialize_infcmd): Update doc on attach and detach commands.
4814 (do_registers_info): Merge in a byte-order problem as a FIXME
4817 * findvar.c (find_saved_register): Avoid problem in current frame.
4818 (read_relative_register): Ditto.
4819 (write_register): Convert byte order on the way out.
4821 * exec.c (file_command): Add.
4822 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
4823 (xfer_memory): Common function between core_xfer_memory and
4825 (exec_xfer_memory): Use it.
4827 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
4829 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
4830 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
4831 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
4833 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
4835 Merge Intel 960 port of gdb, continuing...
4837 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
4838 symbol_file_command): Pass from_tty arg to hush 'em up.
4840 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
4841 Add magic numbers for 960 COFF format.
4843 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
4845 Merge Intel 960 port of gdb, from Intel "1.2" release.

4866 Fri Apr 20 13:47:15 PDT 1990
4869 Thu Apr 19 09:54:28 PDT 1990
4870 Add 'reset' command.
4872 Wed Apr 18 09:48:07 PDT 1990
4873 After opening remote tty, wait for 1 second to go by without input
4874 from it before trying to talk to NINDY (fixes problems with the
4875 Heurikon HK80/V960E).
4877 Mon Apr 4 16:33:05 PDT 1990
4878 Some output was not being suppressed in 'batch' mode.
4880 Thu Mar 22 15:31:11 PST 1990
4881 Ask user if old symbol table should be deleted when new file is

4908 Mon Oct 16 14:15:09 PDT 1989
4909 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
4911 Mon Oct 2 15:56:31 PDT 1989
4913 Added 960CA disassembly support.
4915 To simplify maintenance:
4916 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
4918 - eliminated opcode.h: incorporates tables into i960-pinsn.c
4919 - moved 960-specific routines from i960-pinsn.c to i960-md.c
4920 - made disassembly interface identical to that in gdmp960.
4924 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
4926 * target.h: Allow targets to stack. Add target_has_memory,
4927 _registers, etc. Restructure memory access and "info files"
4928 to walk the target stack.
4929 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
4930 target.c: Change tables to match target.h.
4931 * inflow.c (child_mourn_inferior): pop child_ops.
4932 (generic_mourn_inferior): Use new has_stack flag.
4933 * infptrace.c (child_xfer_memory): New memory regime.
4934 * inftarg.c (child_files_info): New "info files" regime.
4935 * remote-eb.c: New memory regime, new info files.
4936 * remote-vx.c: New memory regime, new info files. Now use
4937 separate targets for VxWorks attachment to machine, and
4938 actually running a process under VxWorks, since one has
4939 stack & execution & regs and the other doesn't.
4940 * remote.c: New memory regime, new info files.
4941 * sparc-xdep.c (fetch_core-registers): New memory regime.
4942 * target.c: New routines and support for stacked targets,
4943 new memory regime, new info files regime.
4946 Generalize section handling for an arbitrary number of sections,
4947 including use of the new BFD (binary file) library.
4948 * gdbcore.h: Add struct section_table.
4949 * exec.c (build_section_table): Iterate all sections and
4950 record what gdb needs to know about them.
4951 (exec_command): Use it.
4952 (exec_xfer_memory): Use the table.
4953 (exec_files_info): Print the table.
4954 * core.c (core_file_command, core_xfer_memory, core_files_info):
4956 * source.c (find_source_lines): Use bfd_get_mtime.
4957 * dbxread.c: Quick changes to make it compile with new BFD.
4958 * utils.c (error): Avoid using bfd_error in generic routines.
4960 * core.c (core_fetch_registers): Get from the ".regs" section of
4962 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
4964 * inferior.h (attach_flag): Export.
4965 * infcmd.c (run_command): use new target_create_inferior.
4966 * infrun.c (child_create_inferior): Don't return result.
4967 * Makefile.dist (VERSION): 3.91.4.
4969 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
4971 * breakpoint.c (bpstat_num): Handle breakpoints which have
4972 since been deleted, such as temporary breakpoints.
4973 infcmd.c (program_info): ditto.
4975 * core.c (core_file_command): Display the frame where the core
4980 * remote-vx.c (target_command): Merge in target command from
4981 targ-vx.c. A few other cleanups.
4983 * TODO, Projects: Lots more stuff to do...
4985 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
4987 Massive changes to wall off the remote-debugging interface
4988 behind a function vector. The port to handle VxWorks targets
4989 is also part of this.
4991 All files: Replace references to renamed functions,
4992 remove references to remote_debugging, remove references to
4993 have_include_file, have_core_file in favor of target_has_stack,
4994 target_has_memory, etc.
4996 * Modularize the breakpoint interface.
4997 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
4998 a breakpoint instruction.
4999 breakpoint.c: struct breakpoint's shadow_contents now sized as
5001 (insert_breakpoints): Vector to target to install breakpoints.
5002 (remove_breakpoints): Vector to target here too.
5003 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
5004 sparc-tdep.c (single_step): Use new breakpoint interface for
5005 the single-step breakpoints.
5006 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
5007 New file, contains routines to insert and remove breakpoints by
5008 reading out the old contents and later replacing them. This is
5009 how ptrace breakpoints work, and many remote systems as well.
5011 * tm-vxworks68.h: New config file, overrides a few things for
5012 Wind River's preferences.
5014 * target.h: New file, for transfer vector used to talk to the
5015 inferior (child, attached, core, exec, remote, etc). All accesses
5016 to the thing being debugged should come through these vectors.
5017 target.c: New file, routines to handle transfer vector.
5018 (various files): Add transfer vectors XXX_ops for the various
5019 targets and pseudo-targets (core files, etc) we support.
5021 * breakpoint.c (bpstat_stop_status): Further explorations of
5022 watchpoints and why things don't work all the time.
5023 (bpstat_alloc): New fn to allocate a bpstat and chain it.
5025 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
5026 the local gdbinit if it doesn't already have it.
5028 * core.c (core_ops): add and install.
5029 Allow core debugging without exec file.
5031 * dbxread.c (free_and_init_header_files): Merge two fns.
5032 (end_symtab): Free named symbol table when a new version comes in.
5033 (read_dbx_symtab): Relocate all kinds of symbols with base
5034 address. First step toward handling different text, data, bss
5036 (add_file_addr_command): Renamed add_file_command.
5037 (add_file_command): Vector to remote handler.
5038 Add "load" as an alias for "add-file" command.
5040 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
5041 non-returning functions.
5043 * exec.c: Add exec_ops, and push it as a target when an exec
5046 * infcmd.c (run_command): Pass executable file name and arg list
5047 separately when starting an inferior. Permit "run" when no exec
5048 file is specified, for VxWorks.
5049 (detach_command): Move to child_detach in inftarg.c.
5051 * inftarg.c: New file. Unix-child-specific routines, and the
5052 child_ops structure.
5054 * inferior.h (registers): Export "registers" as the way for
5055 target dependent register handlers to find gdb's local copy of
5056 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
5057 since it is now used by places that want wait_for_inferior to
5058 handle the grunge but want to see every trap from the inferior.
5060 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
5061 Eliminate remote_debugging hooks in terminal handling.
5063 * infrun.c: Replace start_inferior with child_create_inferior.
5064 Move all the hair of Unix shells and ptrace idiosyncracies into
5065 child_create_inferior, so remote handlers don't have to deal.
5066 Remove running_in_shell. Rename stop_after_attach to
5067 stop_soon_quietly, and use it in a few other places where we want
5068 to just call wait_for_inferior and get control back on the first
5069 trap. trap_expected now never takes a value > 1.
5070 (init_wait_for_inferior): Initialize static vars when a new
5073 main.c (gdbinit): Add new hook for .gdbinit file name, let
5074 it be overridden by config files as GDBINIT_FILENAME.
5075 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
5076 Both of these are used for VxWorks gdb.
5078 mcheck.c: rename include file "gmalloc.c" to avoid problems
5079 with system include file "malloc.c".
5081 param-no-tm.h: New include file, same as param.h but does not
5082 include the default "tm.h" file. This is used in files where
5083 the target is known, e.g. remote-eb.c or sparc-xdep.c.
5085 param.h: Now just a shell that includes tm.h and param-no-tm.h.
5087 remote-vx.c: New file, VxWorks remote debugging support. Uses
5088 RPC routines that are shared with the target system, in directory
5091 remote.c: Vectorize remote interface.
5093 source.c: Globalize source_path, and make an alias "l" for "list"
5094 since we now have the "load" command.
5096 sparc-xdep.c: Use new param-no-tm.h.
5098 symmisc.c (free_named_symtab): Add new function from Wind River.
5099 However, ifdef it out for now while we think about what it should
5102 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
5104 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
5105 non-Unix-children handle this with their own code in the target
5108 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
5109 source and target lists. Add vx-share to default list of include
5110 directories. Add new files to src and target lists: mem-break,
5111 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
5112 ${srcdir} versions of munch and createtags are used.
5114 * valops.c (find_function_addr): Split out of call_function.
5115 (call_function_by_hand): Rename call_function; this function
5116 calls functions in the target by laboriously patching the target
5117 word-by-word with the right stack, args, regs, etc.
5120 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
5122 Handle AMD 29000 a bit better.
5124 * remote-eb.c (readchar): Mask received char log to make it readable.
5125 (remote_start): Pass arguments down to executing program.
5126 Make startaddr unsigned.
5127 infrun.c (start_inferior): Accept args, pass them to
5129 infcmd.c (run_command): Pass args down to start_inferior.
5131 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
5132 the target object file format.
5133 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
5135 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
5136 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
5138 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
5140 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
5141 * TODO: We did a few things, we have more to do though.

5144 * inflow.c (inferior_died): Clear deferred stores.
5146 * Debug problems with dummy frames and calls to the inferior.
5147 * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME): Move to sparc-tdep.c.
5148 * sparc-tdep.c (do_restore_insn): Simplify.
5149 (sparc_frame_find_saved_regs): Simplify and fix what we find.
5150 (sparc_push_dummy_frame): Simplify and fix what we push.
5151 (sparc_pop_frame): Slightly more hair here, deciding whether
5152 we are restoring a saved PC or returning to a return address in %i7.
5153 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
5155 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
5156 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
5157 * obstack.h (chunkfun): ditto.
5158 * defs.h (xmalloc, xrealloc): ditto
5160 * utils.c (quit): Grab the terminal from the child if necessary.
5162 * inflow.c (term_status_command): Rename to term_info, change
5165 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
5166 (is_delayed_branch): Speed up.
5167 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
5168 Still missing some float ops, and needs testing.
5170 * Support for input and output radixes other than base 10
5171 * defs.h (input_radix, output_radix): Declare.
5172 * expread.y (yyparse, parse_number): Handle changes of input
5173 radix, and ambiguous names-or-numbers in radixes >10.
5174 * printcmd.c (print_scalar_formatted): Print formatted hex
5175 numbers in varying column widths.
5176 * valprint.c (val_print): Use output_format to print scalar ints.
5177 (set_input_radix, set_output_radix, set_radix): Create.
5178 (set_output_radix): Set output_format from output_radix.
5179 (_initialize_valprint): add `set radix' but leave the others off.
5181 * main.c (execute_command): Let stupid questions be turned off.
5182 (_initialize_main): Handle "set stupidity", etc.
5184 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
5185 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
5187 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
5189 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
5190 bfd stuff is still screwed up, but with some manual work, it
5193 * breakpoint.c (bpstat_do_actions): Start over if a command
5194 proceeds the inferior, since the inferior will have stopped and
5195 will need to have its new stop-actions taken care of.
5197 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
5198 compiler fits, simplify it.
5200 * gdb.texinfo (directory command): Doc new dir command.
5201 source.c (directory_command): "dir" now puts things on the front
5202 of the path, moves dups up front, and handles multiple names
5203 on the command line, inserting each one in order. It also
5204 blows away cached line and full_filename info.
5206 * stack.c (backtrace_command): Skip "more stack frames follow"
5209 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
5210 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
5211 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
5212 The only odd one was Gould NP1, which had defined vprintf to
5215 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
5216 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
5217 variable, inspect_it.
5218 valprint.c (print_string, val_print): Use the global inspect_it
5219 to indicate whether to print in Epoch style or normal style.
5221 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
5223 * printcmd.c (call_command): add an alias for the "print" command
5224 which runs expressions and doesn't print the result if void.
5225 (print_command_1): implement it.
5227 * command.c: Remove #if 0'd code. Initialize all the fields
5228 in add_cmd (). Rename do_nothing_command to
5229 not_just_help_class_command, and make it externally visible.
5230 command.h: add user_commands to struct.
5231 * main.c (define_command): Don't overload c->function with a char
5232 string as well as a function pointer.
5234 * eval.c (evaluate_subexp): Reinstall tiemann changes to
5235 calling convention of value_struct_elt () that got dropped in
5238 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
5239 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
5241 * tm-sparc.h (POP_FRAME): replace some constants with defines.
5243 * sparc-xdep.c (store_inferior_registers): defer stores to regs
5244 until a good time (e.g. when we are about to run the child),
5245 saving ptrace calls.
5246 * infrun.c (proceed): handle DO_DEFERRED_STORES.
5247 * tm-sparc.h: define DO_DEFERRED_STORES.
5249 * sparc-xdep.c (store_inferior_registers): when storing float
5250 registers, don't store stack regs too. When storing the SP,
5251 however, DO store the stack regs too. This fixes a bug in which
5252 the dummy frame is not recognized when a call_function finishes,
5253 because its frame pointer (in the stack regs) was never
5255 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
5256 even though we don't know how to read them from an inferior.
5257 valops.c (call_function): Comment about storing SP.
5259 * infrun.c (save_inferior_status): Save away the original bpstat
5260 chain so it can be restored later. Install the copied version for
5261 use by whoever saved the status. It will be blow away by
5262 restore_inferior_status, and the original chain restored. This is
5263 important for people who have pointers into the original.
5265 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
5266 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
5267 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
5270 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
5272 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
5273 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
5274 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
5276 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
5278 * Merge Mike Tiemann's multiple inheritance changes from Sun.
5279 Store the baseclasses in a type struct starting from array element
5280 0 rather than from the unusual array element 1.
5282 dbxread.c: the above.
5283 (virtual_context): Add
5284 Read new debug information about which virtual function table
5285 a virtual function is from, and store it in fn_field.fcontext.
5287 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
5288 TYPE_FN_FIELD_STATIC_P.
5290 symtab.c: the above.
5291 valops.c: the above. Handle pointer casts of object *'s.
5292 (search_struct_method): Add.
5293 (value_struct_elt): First arg is now a pointer to a value, and is
5296 valprint.c: the above.
5297 values.c (value_virtual_fn_field): Add type arg. Handle
5298 offsetting to the proper object when calling virtual fns.
5300 (baseclass_addr): Add valuep arg.
5302 * README: Document the current state of BFD config (missing).
5303 * TODO, ChangeLog, Makefile.dist: Roll version.
5304 * WHATS.NEW: Add summary of changes since 3.5.
5306 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
5308 * dbxread.c (read_struct_type): Clear bit vectors whenever
5310 symtab.c (B_CLRALL): define.
5312 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
5313 using == rather than =. Huh... This fixes the dreaded problem
5314 wherein builtin_type_int becomes TYPE_CODE_FLT.
5316 * core.c (info_files): Show the inferior pid.
5318 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
5319 already knows how to look in the source directory.
5321 * Remove psymtab hair from many places. Remove duplicated code
5322 for searching symbol tables. Hide psymtabs from most places.
5323 Make it fast to get from a psymtab to its symtab.
5325 blockframe.c (blockvector_for_pc): Remove psymtab hair.
5326 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
5327 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
5328 dbxread.c: export psymtab_to_symtab, make it work if called N times.
5329 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
5330 new symtab completely. New psymtabs get symtab pointer
5331 initialized to zero. Remove MI warning printf.
5332 symtab.h: Comments. Add psymtab to symtab pointer.
5333 (PSYMTAB_TO_SYMTAB): New macro.
5334 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
5335 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
5337 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
5339 (print_frame_info): Avoid special-casing symbols that have not yet
5342 * source.c (open_source_file): Quick path if we have already
5343 located the source file by its full name.
5345 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
5346 find_pc_psymtab. When a name is found in the misc function
5347 vector, search the symbol table for its mangled name, not the
5348 name that the user typed.
5350 * bfd.h: Fix missing comment terminators, make #endifs match.
5352 * valarith.c (value_less): Handle unsigned int comparisons.
5353 Add FIXME about pointer compares, which assume host and target
5354 pointers are the same.
5356 * command.c (do_nothing_command): lint
5357 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
5358 fix comments on debug symbol format for visibility. Actually set
5359 visibility of symbols.
5360 main.c (echo_command): lint; use <readline/history.h>.
5361 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
5362 obstack.h (_obstack_blank): Rearrange pointer math to avoid
5363 pointing past end of allocated memory; saber complains.
5364 obstack.h: Declare the external functions that we use.
5365 valarith.h: use <string.h>
5366 solib.c (solib_add): lint.
5368 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
5370 * main.c (initialize_main): Default info_verbose to off, now that
5371 symbol reading is fast.
5372 (quit_command): Avoid clobbering exec_bfd while quitting.
5374 * Initial BFD (binary file diddling library) merger:
5375 coffread.c: Change AOUTHDR to struct exe_hdr.
5377 core.c: initialize initialized data at compile time.
5378 (core_file_command): Move from coredep.c, convert to bfd.
5379 (xfer_core_file): Convert to bfd.
5380 exec.c (exec_file_command): use bfd routines.
5382 mips-tdep.c: Remove exec_file_command and friends.
5385 * coredep.c: (fetch_core_registers) Convert core_file_command to
5386 fetch_core_registers.
5387 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
5389 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
5390 (my_bfd_read): More bogosity, which I don't think we call.
5391 (program_name): Remove this atrocity asap!
5393 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
5396 values.c: allocate_repeat_value was not clearing the
5397 optimized_out field.
5398 (value_static_field): minor stylistic fix (wrong macro was used).
5399 valops.c (value_struct_elt_for_address): didn't work for C++
5402 * signame.c (_initialize_signame): Initialize signal names once.
5404 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
5405 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
5406 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
5408 * remote-eb.c: Support user-settable baud rates on the serial port.
5410 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
5412 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
5414 * tconfig/sun3os4: Remove warning about native assembler,
5415 since it also occurs in the xconfig file.
5417 * findvar.c (registers): Allocate some slop after `registers'
5418 to prevent stray accesses from trashing the next variable.
5420 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
5421 on the sun-3, by changing the #ifdef from `sun3' (which is not
5422 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
5423 vars, which happened to follow `registers' in the executable.
5425 * readline/history.c (history_search): Heed gcc-2's advice
5426 and parenthesize && inside ||).
5428 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
5429 tm-29k.c: Insert FSF copyright headers.
5431 * remote-eb.c: Better comments.
5433 * Makefile.dist: Update to 3.91.6.
5434 * TODO: note PREPARE_TO_STORE problem.
5436 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
5438 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
5440 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
5442 * infrun.c (wait_for_inferior, at end): Don't set up
5443 prev_* if the inferior no longer exists.
5445 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
5446 CANNOT_EXECUTE_STACK.
5447 valops.c (call_function): Use it.
5449 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
5451 * inferior.h (PC_IN_CALL_DUMMY): New macro.
5452 infrun.c (wait_for_inferior, 2 places): Use it.
5454 * values.c (value_being_returned): Only use
5455 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
5457 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
5458 right thing for remote-eb.c.
5460 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
5461 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
5463 * blockframe.c: Put get_frame_saved_regs inside #if !defined
5464 (FRAME_FIND_SAVED_REGS).
5466 * findvar.c ({fetch,store}_registers): Check for
5467 REMOTE_{FETCH_STORE}_REGISTER macro.
5469 * findvar.c (get_saved_register): Add argument lval and
5470 change meaning of argument addr.
5471 findvar.c: Change calls to get_saved_register to reflect
5472 new calling convention.
5473 valops.c (value_assign): Use get_saved_register instead of
5474 find_saved_register.
5476 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5478 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
5479 an (uninitialized) pointer to one. Use "&" when passing it
5482 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5484 * coffread.c (getfilename): Use DGUX x_offset and x_name if
5487 * coffread.c (symbol_file_command): Put semicolon after
5489 Put safe_to_init_tdesc_context in #if defined (TDESC).
5490 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
5491 coffread.c: #include <sys/stat.h>.
5492 (read_coff_symtab): Typo: in_source_files -> in_source_file.
5493 Add missing ')' in check for "lc%" and friends. Remove
5495 Declare read_one_sym() at top of file.
5496 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
5497 MC68WRMAGIC can have the same value without causing a duplicate
5500 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
5502 * Allow a Makefile to be built without building the
5503 tm and xm file links that screw up builds in subdirectories.
5504 This is done with `config.gdb none', then you can do things
5505 like `make gdb.tar.Z'.
5506 * tconfig/none: Config file for no target system
5507 * xconfig/none: Config file for no host system
5508 * config.gdb: If no TM or XM files are called out by the
5509 host or target file, don't make links for them.
5511 * cplus-dem.c: Add documentation.
5513 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
5514 simple error, so the user's gdb doesn't crash due to some object
5515 file problem (e.g. somebody is rebuilding the file out from under
5518 * printcmd.c (print_address_symbolic): demangle the symbol.
5520 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
5521 Motorola copyrights in it. Make "make gdb.tar.Z" work.
5522 (alldeps.mak): sort and uniq all results from this; duplicates
5523 hose gdb.tar.Z link building. Remove RCS files from
5524 tconfig and xconfig. Add config files for sun386. Add
5525 a few odd files to OTHERS and HFILES.
5527 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
5529 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
5530 Roll version number to 3.91.5. Make lint work in bindir.
5532 * README: Document cross-debugging and new file structure.
5534 * blockframe.c: Lint. Include "value.h" to declare read_register.
5535 (find_pc_partial_function): remove duplicate line.
5537 * command.h: Lint. Declare error_no_arg and dont_repeat.
5539 * tm-news.h: Remove inadvertently duplicated stuff.
5541 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
5542 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
5544 * config.gdb: Allow `config.gdb host target' form. Clean
5545 up previous change that printed bogus messages when you just said
5548 * core.c: #include "command.h" for lint.
5551 * main.c: Remove some casts of enums. Lint.
5558 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
5560 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
5561 read it from memory. This will allow us to save ptrace calls
5562 eventually. Changed caller single_step too.
5564 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
5565 that we aren't going to use, saving many ptrace calls, especially
5566 when watchpointing or single stepping. Use some #define's for
5568 (store_inferior_registers): Ditto.
5569 (core_file_command): Use some #define's for constants.
5571 * tm-sparc.h: Add #define's for some register numbers, so we
5572 can eliminate the use of random constants in sparc-xdep.c.
5574 * stack.c (frame_command, print_frame_info, up_command,
5575 down_command) Remove frame_changed, since it
5576 causes a bug and doesn't seem to do anything useful. In some
5577 places it was used as a flag, in others as a stack level (?).
5579 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
5580 default is to use the portable (vprintf) version rather than the
5582 * xm-news.h (MISSING_VPRINTF): Add.
5584 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
5586 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
5588 * Remove stuff that forces -Bstatic linking of gdb, and warnings
5589 about linking debugged programs -Bstatic in the sun?os4 config
5590 files in tconfig and xconfig subdirectories.
5592 * main.c (main): Remove unreached exit(0) now that we exit
5595 * Create TODO file for online bug list. There are too many
5596 "little" bugs to keep track of on paper.
5598 * Change Projects file to refer to bug-gdb@cygnus.com
5599 rather than kingdon@ai.
5601 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
5603 * Makefile.dist (VERSION): 3.91.4 now.
5605 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
5606 (condense_misc_bunches): Add sanity check that misc_count is
5607 the same as the number of symbols in the bunch.
5609 * coffread.c: rename init_misc_bunches. Pass an argument
5610 to condense_misc_bunches (a zero).
5612 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
5613 every time we are called; don't rely on our caller to do it.
5614 (add_file): Remove call to init_misc_bunches.
5616 * mipsread.c: Only warn, don't error, if unknown symbol types.
5617 This keeps an old gdb from falling on its face if it sees newly
5618 extended symbol info. Rename init_misc_bunches.
5620 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
5622 * Merge in changes from Per Bothner for DECstations and other
5623 MIPS stuff. The rest is Bothner speaking:
5625 The next message is a merger of Alessando Forin's mips port with
5626 mine. I've tried to use my good if biased judgment to get
5627 the best of both. It *does* need testing.
5629 Some of the changes are general, *not* mips-specific.
5632 Didn't believe in little-endian bit order.
5633 There are still inconsistencies about whether flags
5634 like BITS_BIG_ENDIAN are integer (#if ...) or
5635 boolean (#ifdef ...). I tried to paper over them.
5637 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
5638 Moved some misc_function code that was common to
5639 {dbx,coff,mips}read.c to symtab.c.
5640 In the process, I think I cleaned things up a bit.
5641 At the same time, moved obsavestring and obconcat to symtab.c.
5644 Removed obsolete condense_addl_misc_bunches (use
5645 condense_misc_bunches(1) instead).
5648 Needed to include <sys/dir>, at least on DECstations.
5650 valops.c, mips-tdep.c, tm-mips.h:
5651 Added PUSH_ARGUMENTS macro to support funny argument-pushing
5652 conventions (when STACK_ALIGN is insufficient).
5653 Needed on mips, where doubles need 8-byte alignment,
5654 but ints only need 4.
5657 Removed cruft that was not being used.
5658 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
5661 Print $ before register-names (I think that makes things a little
5663 Never print two instructions, even if one delays.
5664 Removed hex-disassemble set_cmd. (This is not mips-specific,
5665 so I think the argument is whether it is generally worthwhile or not.
5666 I'm inclined to think not, given how easy it is to
5667 convert between radixes in gdb.)
5670 This is basically Alessando's code.
5671 It doesn't use obstacks; I changed it to use obstacks
5672 in a few minor places where using malloc causes a
5673 memory leak. (Probably, more places could/should be changed.)
5674 I added record_misc_function where it was missing.
5675 In symbol_file_command and add_file_command, I tried
5676 to make the code consistent with more recent versions.
5677 Minor sylistic changes in parse_procedure.
5678 Make a .gdbinfo. psuedo-symbol point back to the real
5679 procedure symbol (using the isym field).
5682 This is basically from my port, but with a lot of details
5683 and a number of routines merged in from Alessando's version.
5684 I basically used my code "raw" backtrace (use heuristics
5685 from the actual code, rather than symbol table info) - though
5686 the idea is Alessandro's. I feel my code is a little cleaner
5687 here, particularly in being a little more flexible, such as being
5688 able to handle gcc-produced code (which it now can).
5689 It also doesn't do frame caching (which is not useful
5690 more recent gdb versions).
5691 I also used my code for push_/pop_dummy, more or less.
5692 I tried to incorporate AF's code for testing sigtramp
5693 while backtracing; I probably got it wrong.
5694 Added mips_print_register, which tries to scrunch as much
5695 information as possible on a screen...
5696 Removed the skip-prologue set_cmd. As with hex-disassemble (see
5697 under mips-pinsn.c), I don't see anything mips-specific here,
5698 and I don't see it being all that useful anyway.
5701 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
5702 Use more register names (rather than hard-cases numbers).
5704 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
5706 * Hack up 3.90.11 changes:
5708 * Makefile.dist (depend): parameterize $(GCC).
5709 Add solib.c and solib.o.
5710 (readline): Fix vpath for both absolute or relative SRCDIR.
5712 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
5713 Also, let the part I didn't understand at least compile so
5714 I can test the rest. FIXME.
5716 * dbxread.c: Fix thinko using strcmp.
5717 (init_psymbol_list): declare static.
5718 (partial_symbol_file_open): Comment cleanups better, avoid
5719 cleaning up the string table since the caller will do that.
5720 Move the stat for mod time into symbol_file_command, temporarily.
5721 (There should be a mod time for each symbol file, eventually,
5722 to control its rereading. FIXME.)
5724 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
5725 SunOS, which gives error for shared libs otherwise. (From
5726 Schaefer, probably FIXME needs work for portability.)
5728 * solib.c: Move #include "param.h" to work.
5729 Lowercase all the Uppercase Letters In the Messages.
5730 (find_solib): Clean up inferior_so_name for debug printouts.
5731 Allow no argument, to mean all shared libraries.
5733 * symmisc.c: include param.h to get CLEAR_SOLIB.
5735 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
5737 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
5738 to 3.90.11. ChangeLog entries below are from this.
5740 Wed Jun 13 09:17:39 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)

5746 Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5750 * Makefile.dist (gdb.tar.Z): Change linking of config so it works.
5752 Thu Jun 7 16:22:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu)

5756 Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5758 * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
5759 Put parens around gcc_p in expansion.
5761 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
5763 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
5765 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5767 * Changes for Sun shared libraries:
5768 blockframe.c (find_pc_partial_function): If a non-text symbol
5769 is found, set *address = pc - FUNCTION_START_OFFSET.
5770 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
5771 Disable breakpoints instead of giving an error.
5772 source.c (select_source_symtab): Initialize cs_pst.
5773 symmisc.c: Call CLEAR_SOLIB if defined.
5774 symtab.h: Make text{low,high} CORE_ADDR not int.
5775 (psymtab): New field addr.
5777 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
5778 (record_misc_function): Give correct type for N_DATA symbols.
5779 (condense_misc_bunches): do "misc_function_count = j" regardless
5781 Take code which is shared between symbol_file_command and
5782 add_file_command and put it into partial_symbol_file_{open,read}.
5783 Split add_file_command into add_file_command and add_file.
5784 Make psymtab_to_symtab read in the string table if the file
5786 Two new parameters to read_dbx_symtab and start_psymtab.
5787 tm-sunos.h: New file.
5789 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5791 * infcmd.c: Change cont_command to continue_command and "cont"
5794 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5796 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
5798 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
5800 * values.c (USE_STRUCT_CONVENTION): Check for structures of
5801 size 1,2,4,8 rather than size < 8.
5803 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
5804 as necessary, not just once.
5806 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
5808 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5810 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
5812 * tm-news.h: Add CALL_DUMMY_*.
5814 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
5816 * config.gdb: In list_host, list_target, use ${i}, not $i.
5818 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5820 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
5822 * sparc-opcode.h: Change all store floating-point state register
5823 instructions to have the right match & lose fields.
5825 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5827 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
5829 config.gdb: If srcdir != ., create readline directory and
5830 copy a makefile into it.
5832 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
5833 consistency with POSIX.
5835 * breakpoint.c (bpstat_stop_status): Disable watchpoint
5836 when we exit its exp_valid_block.
5838 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
5840 * Makefile.dist: Bump version to 3.91.3.
5842 * Clean up handling of breakpoint commands (somewhat).
5843 Prompted by Tiemann bug report "cont 10" doesn't work any more.
5845 inferior.h: Add breakpoint_proceeded to inferior status struct
5846 and globals; save it and restore it.
5847 (clear_breakpoint_commands): Cleanup, remove old #define.
5849 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
5850 (save_inferior_status, restore_inferior_status): handle it also.
5851 (proceed): Remove earlier code that set breakpoint_proceeded.
5852 It is now set only in clear_proceed_status.
5853 (clear_proceed_status): Cleanup, use bpstat_clear rather
5854 than clear_breakpoint_commands. No callers need the stop_bpstat
5855 between clear_proceed_status and proceed.
5857 infcmd.c: Add breakpoint_proceeded definition and comment.
5858 (cont_command, jump_command, signal_command): Move call to
5859 clear_proceed_status right next to call to proceed.
5861 breakpoint.c (bpstat_do_actions): Avoid clobbering our
5862 caller's argument while running down the chain of breakpoints.
5863 Use new variable "breakpoint_proceeded" to determine when
5864 a command that it executes moves the inferior past the
5866 (bpstat_clear): Handle NULL argument.
5867 (bpstat_clear_actions): Avoid useless call to
5868 breakpoint_auto_delete.
5869 (delete_breakpoint): Clean up bpstat's that are pointing to
5870 the deleted breakpoint from the stop_bpstat chain.
5871 (breakpoint_auto_delete): Simplify.
5873 * Clean up handling of EOF, error on stdin, etc. This was
5874 prompted by a network problem that caused gdb to go into an
5875 infinite loop filling up its malloc'd memory.
5877 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
5878 not clear_breakpoints_commands, which is now gone.
5879 (main): If command_loop returns (e.g. from EOF on stdin), do
5880 a quit_command (looping back to command_loop if quit_command
5881 doesn't really quit).
5882 (command_loop): check result from command_line_input and
5883 exit if it returns NULL, rather than passing the NULL to
5885 (gdb_readline): Free malloc'd result space before returning
5888 * utils.c (query): Handle C-d to mean "yes", just as if the
5889 input was not a terminal. Also avoid infinite loop if EOF
5890 occurs in mid-input-line before newline. This allows
5891 query to be used at EOF on stdin with reasonable results.
5893 * infrun.c (proceed): Set breakpoint_proceeded.
5895 * values.c (value_as_long): Avoid infinite recursion for enums.
5896 (_initialize_values): Fix typo in help msg (kingdon).
5898 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
5899 RL_LIB for linking. This allows -lreadline for linking
5900 and nothing for dependencies, once readline is a real library.
5902 * config.gdb: Jim Kingdon: give useful error message if the
5903 host or target type is not recognized.
5905 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
5906 it just defines it. Dumb, but deal with it.
5908 * Jim Kingdon suggests:
5909 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
5911 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
5913 * Makefile.dist (VERSION): Bump version # to 3.91.2.
5915 * Clean up Bothner's changes.
5917 * blockframe.c (clear_pc_function_cache): New function.
5918 * blockframe.c: remake cache_pc_function_* static.
5919 * dbxread.c (symbol_file_command): remove references to
5920 cache_pc_function_* variables.
5921 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
5922 * printcmd.c: Avoid kludging a global variable (addressprint)
5923 to avoid printing the address of a string twice. Instead,
5924 pass the format letter 's' down low enough that it can be seen
5925 to avoid this problem.
5926 (print_formatted): Pass format arg to value_print.
5927 (restore_addressprint): Remove function.
5928 (do_examine): Avoid hacking addressprint, cleanups and such.
5929 (print_frame_args): Add a comment to a Bothner change.
5930 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
5931 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
5932 to wipe out the values cached in blockframe.c.
5933 * symtab.c (find_method): Add comment saying how big you must
5934 allocate to be "big enough". Per being terse again.
5935 * valprint.c (val_print): Handle format letter "s" to print
5936 strings without addresses. Add comment to vtbl printing code
5937 which casts with wild abandon. Rearrange reference-printing
5939 @0xaddr: value (print w/addressprint)
5940 value (print w/~addressprint)
5941 @0xaddr (parameter lists w/addressprint)
5942 or nothing (parameter lists w/o addressprint)
5944 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
5946 * Merge more changes from Per Bothner:
5948 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
5949 annoying) that I tried to improve it. Here are my suggestions.
5951 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
5954 Do automatic de-reference when taking the address of a reference.
5956 Don't deref_ref when printing parameter lists.
5958 More attempts at treating refernences properly.
5960 In val_print, if deref_ref==0, don't print dangling " = ".
5962 Add COERCE_REF macro, which de-references an REF.
5964 * Merge changes from Per Bothner:
5966 * Fixed (Sony news)-specific configuration problems.
5967 * Fixed other problems with using vanilla pcc and libc (enum problems;
5968 assumption that vsprintf exists).
5969 * Some major speed-ups (finc_pc_partial_function now caches a match;
5970 parsing avoids duplicate symbol_lookup calls).
5971 * Changed handling of baseclasses (no longer use baseclasses field
5972 of struct type, use the first n_baseclasses fields instead).
5973 * Various minor changes/fixes, most C++-related.
5976 Cache the most previous match from find_pc_partial_function.
5977 (Save both low and high ends of matching function's pc range.)
5978 This speeds up the loop of infrun.c:wait_for_inferior quite
5979 a bit, and makes step/next commands much zippier.
5981 Added an enum->int cast (otherwise, some compilers barf).
5983 No longer set baseclass offset to 0, since multiple
5984 inheritance now mostly works.
5985 Added a number of casts, to shut up compiler warnings
5986 (after stabs where made enums, not ints).
5987 When discarding a symbol table (in symbol_file_command),
5988 must clear the cache introduced in blockframe.c.
5989 Don't convert $vtbl_ptr_type to vtbl any more.
5990 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
5991 Mask off sign bit emitted by g++ for virtual table offset.
5992 Set voffset to -1 (not 1) for static member functions.
5994 Changed parsing/lexing of names to avoid doing symbol lookup twice
5995 (once when lexing to determine symbol class, once for real).
5996 Now only call symbol_lookup once. Fields of 'this' win especially big.
5998 Subpress printing addr twice in the case of 'x/s addr'.
6000 lookup_basetype_type is no longer used.
6001 Add find_methods as recursive helper function to decode_line_1.
6002 This allows multiple inheritance to work.
6003 Also, once one or more matches has been found, do not look in
6004 base-classes. (Baseclass methods would be overridden, anyway.)
6006 Removed baseclasses array in struct type.
6007 Instead of using baseclasses[i], use fields[i-1].
6008 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
6009 Changed sign convention of voffset (previous was inconsistent).
6011 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
6013 Used to assume existence of vsprintf. Re-written to not need it
6014 if HAVE_VPRINTF is undefined.
6016 typecmp was too pessimistic. Made it less so.
6018 Don't print space after address.
6019 If vtable points to a misc symbol (with 0 offset), print it,
6020 since that indicates the actual class of the object.
6021 Changed ype_print_derivation_info to use new inheritance
6022 scheme (without baseclasses vector).
6024 In value_primitive_field, fixed some bugs left over from previous set of fixes.
6025 Also, changes needed because TYPE_BASECLASSES were removed.
6027 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
6029 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
6032 If there is no path set, and the symbols don't indicate what directory
6033 a file was compiled in, look in the current directory. But either
6034 a path or a known compilation directory will prevent this.
6037 Three independent bug fixes:
6038 * Remove the #if 0 block that breaks some stuff.
6039 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
6040 adapt gdb to either SunOS 4.0.* or 4.1.
6041 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
6044 Instantiate the class T when looking for methods in it. (Tiemann@sun)
6047 (type_print) Demangle the name being printed.
6048 (type_print_base) Handle botched demangling without coredump (tiemann).
6051 (check_stub_method): Document routine.
6052 (tiemann) fix bug for no-arg functions
6053 Avoid clobbering beyond end of malloc'd storage.
6054 Terminate the argument list properly.
6056 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
6058 * Changes merged by John Gilmore:
6061 In breakpoint_1, use new print_address_symbolic instead
6062 of find_pc_partial_function. (This forces use of assembler-level
6063 addresses, and avoids misleading non-mangled source-level names.)
6065 Generalize ansi argument such that -1 means skip arglist totally.
6066 Removed global variable print_ansi_qualifiers (which made
6067 code non-reentrant), in favor of extra explicit arguments
6068 to internal routines.
6070 Add new helper function print_address_symbolic.
6071 Use find_pc_misc_function instead of find_pc_partial_function
6072 (since we want assembler-level symbols here).
6074 Print unknown function as just "f (...)", not "f (...) (...)".
6075 Use new fputs_demangled explicitly.
6077 Fixed a typing violation (problem: value.h cannot be imported
6078 without renaming many variable in this file).
6079 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
6080 decode_line_1: Moved forward some never-reached code.
6081 Made decode_line_2 skip function prologues correctly.
6083 fputs_filtered should not demangle by default.
6084 Add new fputs_demangled to demangle on demand..
6086 Change value_struct_elt to use value_primitive_field (using recursive
6087 utility function search_struct_field). This allows foo.bar to work
6088 for multiple inheritance (so far only for data fields).
6089 Change check_field in the same way (recursive helper function
6090 to support multiple inheritance).
6091 (Note: there are more of these problems that I haven't fixed.
6092 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
6093 value_of_this: 'this' symbol name is now just "this", note "$this".
6095 Don't print static members.
6096 Avoid printing "members of <type>" if there are none.
6097 Simplified type_print_derivation_info by merging duplicate code.
6098 Remove useless blank lines in type_print_base (ptype command).
6100 Added declaration of new routine value_primitive_field.
6102 Added value_primitive_field which is generalized version of
6103 value_field that can handle multiple inheritance (non-zero offsets etc).
6104 Re-implemented value_field to call value_primitive_field.
6106 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
6108 * infcmd.c -- insert else to avoid 'delete env' coredump when you
6109 delete the whole environment. Karl Berry reported the bug.
6110 * source.c - fix openp to avoid //'s in filenames, which
6111 trigger an Emacs bug causing it to not be able to find files
6112 when running gdb in a window.
6113 * dbxread.c - zap the #if 0 that botches the add-file code.
6114 It seems to work a lot better without all the code commented out.
6116 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
6118 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
6121 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
6123 * Makefile - added a ${CFLAGS} to a couple of entries,
6124 added remote-sa.sparc.c
6125 * added remote.sa-sparc.c, a modification of remote.c
6126 which conducts a dialog directly with the SparcStation prom.
6127 * breakpoint.c, infrun.c, sparcdep.c added
6128 remote_insert_breakpoint(), and remote_remove_breakpoint()
6129 to breakpoint.c instead of directly writing breakpoint instructions.
6130 * sparcdep.c on remote_debugging,there is no need
6131 to remove signle step breakpoint instructions.
6132 * main.c added "-epoch" flag and "int epoch_interface" to main.c
6134 * printcmd.c - epoch interface sends lisp expressions to open up
6135 epoch windows on inspection.
6136 * valprint.c - added arrayprint, and addressprint and made adding
6137 format controls easier
6138 * wait.h added a couple of undef's because we were getting
6139 complaints about WSTOPSIG and WTERMSIG begin redefined.

6164 Tue Jun 26 04:26:29 1990 Michael Tiemann (tiemann at masham)
6166 * cplus-dem.c (cplus_demangle): New parameter ANSI says whether we
6167 should print ANSI qualifiers (such as `const' and `volatile').
6168 All callers changed to call with ANSI == 1, except from
6169 `check_method_stub', which uses old-style syntax.
6171 * symseg.h (struct fn_field): Remove unneccessary `args' field.
6172 * symtab.h (TYPE_FN_FIELD_ARGS): Redefined.
6174 * values.c (check_stub_method): New function.

6191 Sun Jun 3 22:54:08 1990 Michael Tiemann (tiemann at gzilla)
6193 * blockframe.c (blockvector_for_pc): New function.
6194 * blockframe.c (block_for_pc): Changed to call
6195 `blockvector_for_pc' and get the block itself.
6197 * stack.c (catch_info): New function. Prints info about
6198 exceptions which can be caught in the current frame.
6199 * stack.c (print_frame_label_vars): New function. Similar to
6200 `print_frame_local_vars'.
6201 * stack.c (print_block_frame_labels): Prints out labels that are
6202 defined in this frame. These labels are exceptions that can be
6205 * dbxread.c: Updated to handle N_CATCH symtab types.
6207 Thu May 3 22:10:00 1990 Michael Tiemann (tiemann at teacake)
6209 * valprint.c (everywhere): TYPE_NAME (TYPE) no longer comes in the
6210 form "struct ..." for GNU C++. Don't flush any part of TYPE_NAME
6211 when printing the type.
6213 Wed May 2 22:43:04 1990 Michael Tiemann (tiemann at teacake)
6215 * valprint.c (val_print): Use `baseclass_addr' to access the
6216 baseclasses pointed to via the derived class object at VALADDR.
6218 * values.c (baseclass_addr): New function. Casts derived pointers
6219 to baseclass pointers taking virtual baseclasses and multiple
6220 inheritance into account.

6226 Fri May 4 12:12:55 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6228 * breakpoint.c (watch_command, bpstat_stop_status): Deal with
6229 exp_valid_block field correctly.
6231 * infrun.c (wait_for_inferior): When checking "don't even think
6232 about breakpoints" if stop_signal == SIGTRAP && trap_expected,
6233 also check step_resume_breakpoint.
6234 Insert breakpoints and continue (not step) if
6235 step_resume_break_address != NULL, even if another_trap.
6236 If trap_expected and we enter sigtramp, then set up a
6238 If trap_expected is set when we hit the step_resume_break,
6240 When calling resume and trap_expected says tell resume to step
6241 (2 places), also check step_resume_break_address.
6243 * infrun.c (wait_for_inferior): Don't set
6244 prev_{pc,sp,func_{start,name}} before calling wait ().

6252 Restore old code which distinguishes between trap_expected and
6253 running_in_shell, just make the latter take any non-TRAP signal,
6256 * values.c (allocate_value): Zero VALUE_OPTIMIZED_OUT flag.
6258 * Makefile.dist (pinsn.o): Use PINSN_CC to compile.

6402 to remote_fetch_registers.
6404 * mips-tdep.c (_initialize_mipsdep): Remove hex_disassembler
6405 and re-write skip_prologue to use add_set_cmd.
