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

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

58 * coffread.c: Even without TDESC, need to zap "@" symbols.
59 Don't register for wierd format names; change the names in BFD.
61 * alloca.c, language.c, tdesc.c: Lint.
62 * tdesc.c, tdesc-lib: FIXME: remove these.
64 Tue Nov 12 19:30:22 1991 John Gilmore (gnu at cygnus.com)

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

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

100 m88k-xdep.c, main.c, printcmd.c, pyr-xdep.c, source.c,
101 sun386-xdep.c, symm-xdep.c, umax-xdep.c, values.c, xcoffread.c:
102 Change all instances of use of fixed args concat() to variable
103 args concat() now located in libiberty.
105 Tue Nov 12 07:23:46 1991 John Gilmore (gnu at cygnus.com)
107 * Makefile.in: Add xcoffread.c, xcoffexec.c.
108 * xcoffread.c: New file for handling AIX mangled-coff files.
109 * xconfig/rs6000, tconfig/rs6000: New files.

111 * rs6000-pinsn.c, rs6000-tdep.c, rs6000-xdep.c, tm-rs6000.h,
112 xm-rs6000.h, rs6k-opcode.def, rs6k-opcode.h: New files.
113 * xcoffexec.c: New file for handling AIX shared libraries.

129 * dwarfread.c (dwarf_psymtab_to_symtab): Remove leftover call
130 to do_cleanups() which resulted from a previous change.
132 * elfread.c: Re-enable compilation of register_addr() stub
133 whenever it is not supplied by coredep.c
135 Sat Nov 9 00:40:32 1991 John Gilmore (gnu at cygnus.com)
137 Add tracking of object files (that contain symbols) to gdb.
138 This includes a "struct objfile" that owns symtabs and psymtabs
139 that were read in from that binary file.
141 * symfile.h: Add struct objfile. Add pointer to the objfile
142 into the struct sym_fns.
143 Replace global `symfile' and `symfile_mtime' with
144 `symfile_objfile'. Add global object_files chain.
146 * symfile.c: Move param.h above symtab.h.
147 (sort_misc_function_vector): Add.
148 (syms_from_objfile): Was syms_from_bfd.
149 (symfile_open): Now returns objfile.
150 (allocate_objfile): New.
151 (free_objfile): New, replacing free_all_.*symtabs.
152 (symfile_init): Takes objfile arg, puts it in sym_fns result.

154 (allocate_symtab): Takes objfile as new parameter, chains them.
155 Handle INIT_EXTRA_SYMTAB_INFO.

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

172 (dbx_lookup_type): Handle null typevector.
173 (dbx_alloc_type): Check file number, not sym number, for -1.
174 (find_symbol_in_list): Add for xcoffread.
175 (start_symtab): Default typevector is empty. Keep reusing same
177 (end_symtab): Take objfile argument and pass it to
178 allocate_symtab. Don't make a symtab if no blocks or symbols.
179 Handle empty typevector.
180 (push_context): New function for context stack nesting.
181 (read_type): Mark FIXME where we need to reintroduce type smashing.
183 * buildsym.h (pop_context): Macro, paired with push_context.
184 (subfile_stack): Move here from dbxread.c.
186 * coffread.c (end_symtab, read_coff_symtab): Take and use objfile arg.
187 (read_coff_symtab): Cleanup by freeing objfile, not all symtabs.
189 * mipsread.c (read_mips_symtab, parse_partial_symbols, parse_fdr,
190 new_psymtab, new_symtab): Take and use objfile arg.
192 * dwarfread.c (scan_compilation_units, start_psymtab,
193 process_dies, end_symtab, dwarf_build_psymtabs,
194 read_lexical_block_scope, read_func_scope, read_file_scope): Take
195 and use objfile argument.
196 (psymtab_to_symtab_1, read_ofile_symtab): Don't take or use file
197 descriptor. Use BFD internal functions instead.
198 (end_symtab): Call global allocate_symtab.
200 * elfread.c, target.c: Minor changes to accommodate objfiles.
201 * symtab.h: partial_symbol_table has no symfile_name member now.

203 (struct symtab): Add objfile * and objfile_chain * of symtabs.
204 (struct partial_symtab): Add objfile * and objfile_chain * of
205 psymtabs. Remove symfile_name.

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

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

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

618 generic routines for calling inferior functions.
620 * blockframe.c (inside_main_scope, inside_entry_scope): New.
622 * copying.awk: Filter formfeeds out of copying & warrantee.

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

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

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

955 parser, both for language-independence, and so that scopes can
958 * language.h, language.c: New files for language-specific macros,
959 declarations, and definitions.
963 * main.c (main): If error() is called during early
964 initialization, print its message and then exit(1) from GDB.
966 * valprint.c (type_print_base): Avoid printing garbage for ints
968 (_initialize_valprint): Warn about host/target size assumption;
969 improve long long support slightly.
971 * convex-tdep.c (comm_registers_info): Avoid parsing decimal and
972 hex -- let parse_and_eval_address do it.
974 * doc/gdbint.texinfo (Languages): Doc how to add a language.
976 * Makefile.in: Cope with new files and removed files.
978 Tue Sep 17 08:37:41 1991 John Gilmore (gnu at cygint.cygnus.com)
980 Add Andrew Beers' changes for Modula-2 support. His ChangeLog
981 entries are enclosed herein. Not all of these changes
982 have been merged into the master GDB sources -- check the
983 ChangeLog above here for the merge log.
985 Mon Jun 3 17:05:45 EDT 1991
987 m2-exp.y Created. Tested outside of GDB for a few days. Proper
988 operators were added, C specific operators and tokens
989 removed. yylex() revamped to some extent. Still things
990 missing from the grammar, such as sets.
991 Tested for two weeks in GDB v3.5.
993 Tue Jun 11 17:23:48 EDT 1991
995 m2-exp.y Added boolean constants TRUE and FALSE to the grammar
996 so they are built-in. Sort of a hack.
998 Fri Jun 14 12:53:51 EDT 1991
1000 m2-exp.y Added range checking for numeric constants. Any numeric
1001 constant is assumed to be of builtin type INTEGER unless:
1002 (1) it is octal or hexadecimal, in which case it is a
1003 CARDINAL; (2) it is too big to fit into an INTEGER, in
1004 which case it is a CARDINAL.
1005 eval.c Added simple range checking for +, -, and * on integers.
1006 Doesn't work very well for *, since 6 * 1,000,000,000 =
1007 1,705,032,704, which fails the simple test of result >=
1008 first_operand, no matter in what order the operands are.
1010 Tue Jun 18 14:11:30 EDT 1991
1012 Broke the parser into parts, one containing the C grammar and the other
1013 containing code to be shared by all of the grammars.
1015 The following files no longer exist:
1020 The following files were added:
1022 c-exp.y (The C grammar)
1023 m2-exp.y (The Modula-2 grammar)
1024 parser-code.c (Code that is shared by the above grammar)
1028 Makefile.dist Changed to reflect the above dependencies. NOTE: It is
1029 now necessary to use the Bison compiler compiler, since it
1030 will generate function/variable prefixes other than yy.
1032 Tue Jun 18 16:47:49 EDT 1991
1034 symtab.[ch] Added the external variable working_lang, than holds the
1035 value of the current working language.
1036 Added the ennumerated type language_mode, with the values
1037 language_auto and language_manual, the former meaning that
1038 GDB sets working_lang as needed, and the latter meaning
1039 that the value of working_lang is totally under user
1041 symtab.[ch] Added the Modula-2 pervasive types INTEGER, CARDINAL,
1042 REAL, BOOLEAN and CHAR. Also added the type codes
1043 TYPE_CODE_BOOL and TYPE_CODE_CHAR.
1044 utils.c Added set_language_command and show_language_command to
1045 implement the GDB support commands "set language" and
1047 expression.h A number of identifiers were added to the type exp_opcode
1048 to facilitate Modula-2 builtin functions, integer
1049 division, and array indexing.
1051 Wed Jun 19 13:25:58 EDT 1991
1053 language.h Added the macro STRICT_TYPE, which evaluates to non-zero
1054 if the language specified by working_lang requires the use
1055 of strict typing of expressions. Eventually, even this
1056 will be able to be changed by the user.
1057 Added the macro RANGE_CHECK, which evaluates to non-zero
1058 if the language specified by working_lang requires the
1059 checking of a value against the domain of its type.
1060 Eventually, even this will be able to be changed by the
1062 language.[ch] Predicates involving types (simple_type, ordered_type,
1063 same_type, integral_type, numeric_type, character_type,
1064 boolean_type, float_type) are added. These predicates are
1065 based on the current value of working_lang, and are handy
1068 Wed Jun 19 15:39:34 EDT 1991
1070 eval.c Added the function type_array_rank which computes the rank
1072 valarith.c Added the funtion value_bool, which when given a integer
1073 value.h value (ie. struct value *) as an argument, it returns a
1074 boolean value (ie. struct value *) true if that integer
1075 is non-zero, and a boolean value false otherwise.
1076 valprint.c Added cases for TYPE_CODE_BOOL, so Modula-2 BOOLEAN values
1077 will print out properly.
1079 Wed Jun 19 16:36:34 EDT 1991
1081 valops.c Added the function value_capitalize, which returns it
1082 value.h argument capitalized if its argument is a lowercase
1083 letter, or the argument unchanged if its argument is not a
1085 valarith.c Added the function range_check_p, which returns non-zero
1086 value.h if its value argument is between the integral bounds upper
1088 Added the function range_check_enum_p, which makes sure
1089 that its value argument is a valid member of the domain of
1091 Added the function range_check_range_p, which makes sure
1092 its value argument lies between the upper and lower bounds
1093 of its type argument, which must be a ranged type.
1094 Added the function check_array_index, which range and type
1095 checks an index of an array.
1096 Added the function value_multi_subscript, which computes
1097 array[idx1,idx2...idxN], given a value array and an array
1098 of values representing indicies.
1099 values.c Changed value_from_long to work with TYPE_CODE_CHAR and
1100 unpack_long to work with TYPE_CODE_BOOL and
1103 Wed Jun 19 18:04:08 EDT 1991
1105 symtab.c Stored pervasive types in a structure and make
1106 lookup_pervasive_type() a lookup function that was based
1107 on working_lang. If lookup_pervasive_type() returned
1108 non-zero, then that value was returned (a fix, since
1109 before it simply wouldn't return the pervasive type.)
1110 language.h Added the macro CAST_IS_CONVERSION, which evaluates to
1111 non-zero if the language specified by working_lang means
1112 "conversion" when it says "cast".
1113 valops.c Added the function value_real_cast(), which performs a
1114 value.h *cast*, not a *conversion*, which is what value_cast()
1115 does when it can. In particular,
1116 value_cast(<float_type>,4) = 4.0, while
1117 value_real_cast(<float_type>,4) = some mess.
1118 eval.c Modula-2 builtin functions implemented: ABS, CAP, CHR,
1119 parser-code.c FLOAT, HIGH, MAX, MIN, ODD, ORD, TRUNC, and VAL.
1120 expression.h Added macros MAX_OF_TYPE and MIN_OF_TYPE to work with MAX
1121 and MIN on integral types. *NOTE*: These are currently
1122 hardcoded to work only if there are 8 bits per storage
1124 eval.c Made logical functions call value_bool to return a
1125 properly typed boolean value, based on working_lang.
1127 Thu Jun 20 11:55:27 EDT 1991
1129 valprint.c Types now print out in a Modula-2 fashion. This works for
1130 the cases when the type is printed out step-by-step, that
1131 is, it doesn't work when the name of a structured type
1132 (which includes the keyword "struct", etc.) is simply
1134 FIXME: Perhaps this is bad. Parts of it seem to kludgey,
1135 since type specifications in C and Modula-2 are very
1136 different. The C printing of a type is very recursive,
1137 whereas in Modula-2 it is generally very simple. C has
1138 type prefixes and suffixes, which have no real analogue in
1139 Modula-2. Maybe type_print() should call a language
1140 specific type printer. This is also advantageous if we
1141 compile GDB to exclude some of the languages. We'll just
1142 leave those functions out.
1144 Thu Jun 20 16:57:10 EDT 1991
1146 dbxread.c When reading the complete symbol table in (via
1147 psymtab_to_symtab()), the number and types of function
1148 arguments are added to a function type. define_symbol()
1149 calls add_param_to_type() to accomplish this.
1150 Assumption: when we come across a function definition
1151 (N_FUN symbol with an 'f' or 'F' in the name), its
1152 arguments will appear before another function definition.
1153 When a function is found, a pointer to its type is placed
1154 in the global in_function_type. Changes that
1155 add_param_to_type() makes are to this global.
1156 valprint.c The type of a function now includes (for Modula-2) the
1157 types of its parameters.
1158 eval.c Type checking and a check for the proper number of
1159 arguments is now done for function calls. Not sure of the
1160 impact this has on C++ member function yet.
1162 Thu Jun 20 19:58:48 EDT 1991
1164 valprint.c Rewrote the type printer. Broke it into two language
1165 specific parts, adding the functions type_print_m2() and
1167 An unfortunate consequence is this: if you debugging a C
1168 program in Modula-2 mode (why?), info types does not work
1169 well with regular expressions, since the types are printed
1170 out in Modula-2 terminology, but stored in C terminology.
1171 language.[ch] Added the functions new_type_last(), type_keyword(), and
1172 type_sep() to aid in the printing of typedefs.
1173 symtab.c Made the printing of typedefs as language independent as
1174 possible through calls to new_type_last(), type_keyword(),
1177 Fri Jun 21 11:50:26 EDT 1991
1179 dbxread.c Check all incoming ennumerated types. If it looks like
1180 Modula-2's BOOLEAN type, then change the type_code of the
1181 type to TYPE_CODE_BOOL so we can process it as a boolean
1183 valprint.c Replaced some of the 0x%x with calls to sprintf and
1184 hexformat() in val_print().
1185 language.[ch] Added the function hex_to_string(), which converts its
1186 integral argument to a hexadecimal number (format is
1187 language based) and returns the result as a string.
1189 Mon Jun 24 12:25:07 EDT 1991
1191 valprint.c Some functions call type_print_1() directly, instead of
1192 value.h using type_print(), so they can specify where (column) to
1193 print things. Since type_print() takes care of language
1194 dependence, that needs to be called first. Added a
1195 parameter depth to type_print() (so it is now like
1196 type_print_1). Changed type_print to type_print_at, and
1197 made type_print a macro that passes a depth argument of
1199 symmisc.c Changed all calls to type_print_1 to calls to
1201 Makefile.dist Made it possible to build GDB for a specific set of
1202 depend languages. Do this by passing a definition for the macro
1203 LANGS to make. LANGS should be a string containing a
1204 space-separated list of language names (ie. LANGS="c m2").
1205 The default is to build all languages. Note that grammar
1206 files must follow the naming convention of <lang>-exp.y.
1207 gdb.lang This holds the current value of the LANGS macro. It is
1208 examined every time make is called, and is updated if
1210 eval.c Added #ifdef _LANG_<lang> to these files.
1211 expread.c Still need to add them to dbxread.c and coffread.c.
1219 Mon Jun 24 16:33:11 EDT 1991
1221 language.[ch] Added the functions hexformat_pre() and
1222 hex_to_string_pre(), which take a prefix argument to
1223 include in the format string. Thus, hexformat_pre("08") will
1224 return "0x08x" (if the working language is language_c).
1225 Made hexformat() and hex_to_string() calls to the above
1226 with "" as the prefix argument.
1228 am29k-pinsn.c, arm-pinsn.c, breakpoint.c, convex-tdep.c, exec.c, core.c,
1229 dbxread.c, i386-pinsn.c, i386-stub.c, i386-xdep.c, i960-pinsn.c,
1230 infcmd.c, inflow.c, m68k-pinsn.c, m68k-stub.c, m88k-pinsn.c,
1231 mips-pinsn.c, mips-tdep.c, ns32k-pinsn.c, printcmd.c, pyr-pinsn.c,
1232 pyr-tdep.c, pyr-xdep.c, remote-vx.c, remote.c, solib.c, source.c,
1233 stack.c, sun386-xdep.c, symfile.c, symm-xdep.c, symmisc.c, tahoe-pinsn.c,
1234 valprint.c, vax-pinsn.c
1236 Changed all occurences of 0x%[0-9]*l*x in printf format strings to
1237 calls to hexformat() and hex_to_string(). Format strings without
1238 the leading "0x" were ignored.
1240 depend Updated to take the above into account.
1243 Tue Jun 25 15:27:18 EDT 1991
1245 symtab.h Added the types range_mode_t, range_check_t, type_mode_t,
1246 and type_check_t to keep track of the current state of
1247 range and type checking.
1248 main.c Added the variables range_mode, range_check, type_mode,
1249 and type_check to record the current state of range and
1250 type checking. Added initialization code to main().
1251 language.h Changed the macros STRICT_TYPE and RANGE_CHECK to examine
1252 the above variables.
1255 Tue Jun 25 17:57:08 EDT 1991
1257 dbxread.c process_one_symbol() updates the variable (enum language)
1258 source_lang based on the extension of the filename
1259 contained in the N_SO sybmol that started this symtab.
1260 When end_symtab() is called, the value of source_lang is
1261 put into the language field.
1262 stack.c select_frame() sets working_lang (and possibly type_check
1263 and range_check) to the language field of the symtab
1264 associated with the frame that is selected if working_mode
1265 is language_auto. If working_mode is language_manual, a
1266 warning is printed and working_lang is not set.
1267 language.c Added the function set_type_range(), which sets the value of
1268 type_check and range_check (if their modes call for
1269 automatic setting) based on the current value of
1270 working_lang. A non-zero argument will cause the current
1271 settings to be output.
1274 Wed Jun 26 14:51:40 EDT 1991
1276 eval.c Added range checks on assignment.
1277 m2-exp.y Added the grammar for sets to the language. Currently,
1278 these do not do anything except print an error message.
1280 Wed Jun 26 17:01:04 EDT 1991
1282 m2-exp.y Added the ability for parse_number() to parse negative
1283 numbers. A global flag is set upon encountering a unary
1284 minus. This was done to make, for example, 1 parse as a
1285 CARDINAL, and not as an integer, per Wirth's examples in
1286 Programming in Modula-2 ed.4.
1287 valprint.c Added support for "set radix 2" by then setting
1288 output_format to 't'.
1289 eval.c Implemented range checking on subrange types. Added calls
1290 to range_check_range_p for BINOP_ASSIGN and BINOP_VAL.
1291 Implemented MIN and MAX for ennumerated types. The
1292 minimum value of an ennumerated type is defined by Wirth
1293 as the first identifier, and the maximum as the last.
1294 m2-exp.y Made octal numbers ending with "B" be characters and those
1295 ending with "C" be numbers, per Wirth's book. (p. 34)
1297 Thu Jun 27 14:11:52 EDT 1991
1299 stack.c select_frame() now only sets working_lang, it does not
1300 notify the user. If working_mode is language_manual, then
1301 a warning is issued once.
1302 main.c At the end of each call to execute_command(), working_lang
1303 is checked against the local static (enum language)
1304 current. If they differ and working_mode is
1305 language_auto, the new settings of language, type and
1306 range checking are printed out.
1307 stack.c Modified frame_info() to include the language of the
1308 current frame in the output of "info frame".
1309 language.[ch] Added the function language_str() which returns the name
1310 of the current language.
1312 Fri Jun 28 15:33:14 EDT 1991
1314 m2-exp.y Added the built-in procedures INC, INCL, DEC, and DECL to
1315 the language. INCL and DECL currently cause an error,
1316 since sets are not implemented yet. INC and DEC are
1317 implemented as PREINCREMENT/PREDECREMENT with one
1318 argument, and as ASSIGN_MODIFY with two arguments.
1319 eval.c Added type checking to the above cases.
1320 value.h Added not_lval_constant to the lval_type ennumerated type.
1321 not_lval_constant means that the value is a constant
1322 value; that is 3 or 'a' or TRUE, not as in a constant
1323 identifier. This is used to help coerce numbers such as 3
1324 to either signed or unsigned numbers.
1325 valops.c Added the function value_coerce_constants() which coerces
1326 constant integers as following: if one is a constant and
1327 the other is not, the constant's type is set to the type
1328 of the other argument. If both are constants and one is
1329 signed, the other is converted to a signed constant.
1331 Sat Jun 29 17:26:29 EDT 1991
1333 valarith.c Added a better range checker. It now checks range
1334 (successfully) on integral operations [+-] (signed and
1335 unsigned) for any C sized type. Still does not work well
1336 for multiplication.)
1337 int_in_size() returns an integer that is coerced to fit into
1338 specified number of bytes.
1340 Mon Jul 1 13:04:14 EDT 1991
1342 language.[ch] Added the function binop_result_type(), which returns the
1343 builtin (struct type *) type that would be the result of a
1344 binop on the two values V1 and V2.
1346 Wed Jul 3 19:22:53 EDT 1991
1348 source.c Extended source_info() to include the source language in
1349 the output from "info source".
1351 Fri Jul 5 13:48:52 EDT 1991
1353 utils.c Moved the support functions for the GDB set/show commands
1354 dealing with language into language.c.
1355 language.c Added the function language_info(), which displays info
1356 about the current working language, type and range check
1357 settings. Called via the GDB command "info language".
1358 Added an initialization routine _initialize_language(),
1359 that sets defaults for the language, type and range
1360 variables and sets up the new GDB commands.
1361 main.c Language setup moved to language.c.
1364 Mon Jul 8 10:10:22 EDT 1991
1366 valarith.c Debugged the range checker for arithmetic. Still does not
1367 work for multiplication very well.
1369 Mon Jul 8 12:40:37 EDT 1991
1371 language.[ch] Added the function value_true() which returns non-zero if
1372 its argument represents a boolean true value.
1373 breakpoint.c Changed breakpoint_cond_eval() to call value_true() to
1374 check the truth of an expression.
1376 Thu Jul 11 12:51:34 EDT 1991
1378 language.[ch] Added the predicate structured_type(), which returns
1379 non-zero if the argument is a structured type.
1380 Added the predicate pointer_type(), which returns non-zero
1381 if the argument is a pointer type.
1382 eval.c Added the ability to do addition and substraction on
1383 pointers and integers. This case simply bypasses the
1386 Thu Jul 11 14:41:42 EDT 1991
1389 Added the symbol N_DEFD (0x4a) which is a definition
1390 module dependency that is used by the GNU Modula-2
1391 compiler and the linker. It is not important to GDB,
1392 except that [dbx|coff|mips]read.c should ignore these
1395 Fri Jul 12 16:07:00 EDT 1991
1397 valprint.c Changed the TYPE_LENGTH(type) >= 0 to TYPE_LENGTH(type) >
1398 0 in val_print(). Also added statements to the else part
1399 to coerce type (argument to val_print) to a pointer type
1400 if it is an "array of unspecified length".
1401 valops.c Added the function value_m2_string(), which returns a
1402 (value) value which is a constant string, whose type is
1403 (ARRAY [0..n] OF CHAR). The length field of the type
1404 structure is set to zero, so it will be interpreted as an
1405 "array of unspecified length".
1406 stack.c Moved the language/frame mismatch check to
1407 main.c:execute_command().
1408 main.c The working language is recorded each time
1409 execute_command() is executed. If working lang has
1410 changed during its execution, then the new
1411 language/type/range info is printed out for the user. If
1412 the working language does not match the language of the
1413 frame, a warning is issued.
1415 Sat Jul 13 16:16:39 EDT 1991
1417 eval.c Moved all the type-checking stuff for operators to
1418 language.[ch] language.c. This is so we can keep language-specific
1419 stuff (like for what type operators are defined) in
1421 language.[ch] Added the function binop_type_check(), which checks to see
1422 if its two (value) arguments are type-compatible with its
1423 opcode argument. The opcode should represent an operation
1424 involving an operator. Also added the macro function
1425 unop_type_check, which calls binop_type_check with a
1426 NULL second argument.
1427 expprint.c Added Modula-2 operators to the op_print_tab, so info
1428 expression.h break works correctly. Also added "op_string", which
1429 returns the string corresponding to the (enum exp_opcode)
1430 opcode that is its argument.
1433 Sat Jul 13 18:26:18 EDT 1991
1435 coffread.c Added code to record the type of function arguments with
1436 each paricular function. Code is very similar to that
1438 dbxread.c Moved add_param_to_type() to symtab.c
1439 symtab.[ch] Added function add_param_to_type() from dbxread.c
1441 *** NOTE: The above additions have not been tested.
1443 Mon Jul 15 12:50:47 EDT 1991
1445 langauge.[ch] Added the functions type_error and range_error, which work
1446 like error() except if the type/range mode is set to
1447 *_mode_warn, then they do not do a return_to_top_level(),
1448 but merely print a warning.
1449 Also changed [set|show]_[type|range]_command() to support
1450 the new "warn" feature.
1452 Thu Jul 18 17:50:54 EDT 1991
1454 mipsread.c Added code to record the type of function arguments with
1455 each particular function. Code is very similar to that
1458 *** NOTE: The above additions have not been tested.
1460 Fri Jul 19 11:19:10 EDT 1991
1462 defs.h Added macros MAX_OF_SIZE, MIN_OF_SIZE, UMAX_OF_SIZE, and
1463 UMIN_OF_SIZE, which when given a size of a numeric type,
1464 return the maximum and minimum value it can hold. UMAX...
1465 and UMIN... return the result for unsigned types.
1466 symtab.h Added the macros MAX_OF_TYPE and MIN_OF_TYPE to operate on
1467 struct types. They call above macros.
1468 dbxread.c Renamed the MAX and MIN_OF_TYPE macros to ..._OF_CTYPE to
1469 avoid a name conlict with the above.
1470 c-exp.y Added range checking on numeric constants in
1471 parse_number() for completeness.
1472 valarith.c Made binop_user_defined_p() and unop_user_defined_p()
1473 return 0 if working_lang is not language_c.
1475 Thu Aug 8 14:17:22 EDT 1991
1479 breakpoint.c Documentation strings of some commands changed to
1480 eliminate the references to the C language where
1483 Tue Aug 13 15:48:03 EDT 1991
1485 m2-exp.y Added qualified identifiers to the grammar. The semantics
1486 are slightly different from those of the GDB operator ::
1488 m2-exp.y Added a rule to each grammar of the form: start ::= exp |
1489 type_exp, where type_exp is any valid type expression.
1491 eval.c Added the opcode OP_TYPE, and an error case in eval.c.
1492 printcmd.c Modified ptype_command() so it actually parses the input
1493 (necessary for type expressions with scope qualifiers).
1494 Added the function ptype_eval() which expects an
1495 expression composed of one OP_TYPE element.
1496 *.[ch] Replaced all occurences of parse_c_expression with
1498 *.[ch] Replaced all occurences of parse_c_1 with parse_exp_1
1500 [End of ChangeLog entries from Andrew Beers for Modula-2 support.]
1502 Mon Sep 16 17:19:46 1991 John Gilmore (gnu at cygnus.com)
1504 Small fixes from Peter Schauer:
1506 * infrun.c (child_attach): Lint.
1507 * solib.c (find_solib): Handle shared libs version 2.
1509 Small fixes from David Wood:
1511 * xm-ultra3.h (SYS_SIGLIST_MISSING): Typo.
1515 * remote-vx.c: Move <stdio.h> to top, for FILE. Fix from
1516 John S <basrai%kanga.dnet@c3po.sm-alc.af.mil>.
1518 * utils.c (wrap_here): Avoid wrap action of fputs_filtered if
1519 chars_per_line is at maximum (user typed `set width 0'). Fix
1520 from Andreas Schwab <schwab@ls5.informatik.uni-dortmund.de>.
1522 Tue Sep 17 17:31:04 1991 Stu Grossman (grossman at cygnus.com)
1524 * coredep.c: include ptrace.h where necessary.
1525 * mipsread.c(parse_lines): fix unsigned char problem that was
1526 messing up line numbers on SGI's and possibly other MIPS based
1528 * infrun.c (child_create_inferior): use better test to check
1529 return val from setpgrp().
1530 * tm-irix3.h, xm-irix3.h, tconfig/irix3, xconfig/irix3: add these
1531 for sgi/irix support.
1533 Wed Sep 18 04:33:31 1991 Per Bothner (bothner at cygnus.com)
1535 * mipsread.c (parse_symbol): Put non-static procedures
1536 in the global block.
1538 Fri Sep 13 00:14:52 1991 John Gilmore (gnu at cygnus.com)
1540 Patch together `text_start' and `text_end' for 29K port.
1542 * exec.c (exec_command): If NEED_TEXT_START_END, define the
1543 variables and set them based on the exec file.
1544 * am29k-tdep.c: declare text_start.
1545 * valops.c (call_function_by_hand): declare text_end.
1547 * inferior.h: Eliminate CANNOT_EXECUTE_STACK in favor of
1548 defining CALL_DUMMY_LOCATION as BEFORE_TEXT_END. This is
1549 because machines that do this will also have to know to
1550 set NEED_TEXT_START_END. Besides, it was a redundant way to
1552 * tm-29k.h, tm-convex.h, tm-np1.h: Eliminate
1553 CANNOT_EXECUTE_STACK, define CALL_DUMMY_LOCATION and
1554 NEED_TEXT_START_END.
1556 Thu Sep 12 00:22:24 1991 John Gilmore (gnu at cygint.cygnus.com)
1558 AMD 29000 changes from David Wood <wood@david.ultra.nyu.edu>:
1560 * Makefile.in (CLIBS): Put XM_CLIBS and TM_CLIBS at end.
1561 Pass MUNCH_DEFINE to munch whenever we run it.
1562 * am29k-pinsn.c (print_insn): Handle NOP specially. Avoid %#x
1563 format string; use 0x%x instead.
1564 * am29k-tdep.c: Use DUMMY_SAVE_GREGS and RETURN_REGNUM.
1565 * ultra-xdep.c, xm-ultra.h: New files for Ultracomputer host system.
1566 * xm-rtbsd.h: New host support for RT/PC running BSD Unix.
1567 * inflow.c: Handle `short' process group IDs.
1568 * infptrace.c (fetch_register): Support CANNOT_FETCH_REGISTER,
1569 and check for ptrace errors.
1570 * coffread.c (SDB_REG_TO_REGNUM): Define if not already.
1571 (coff_symfile_init): Initialize text_bfd_scnum.
1572 (read_coff_symtab): Use it to find the text [and absolute?] sections.
1573 * ../config.sub: Add vendor nyu and os "sym[1-9]*".
1574 * configure.in: Add hosts rtpc-*-* and a29k-*-*.
1575 Merge target arm case with other "easy" cases. Add target
1576 cases a29k-*-none (rehack of am29k), a29k-*-kern (remote to
1577 Ultracomputer kernel), and a29k-*-sym1 (ultracomputer OS's user
1579 * minimon.h, remote-adapt.c, remote-mm.c: Add.
1580 * munch: Cope with RT/PC putting fns in data segment.
1581 Restore ability to override `nm' by specifying MUNCH_NM.
1582 * xconfig/rtbsd, xconfig/ultra3: New host systems.
1583 * tconfig/a29k: Rename from tconfig/am29k. Add remote-mm
1584 and remote-adapt. Remove encapsulated coff #define's (the
1585 support should go in BFD, and gdb shouldn't know or care).
1586 * tconfig/a29k-kern: Same, but for remote kernel debugging.
1587 * tconfig/ultra3: For debugging user processes on Ultra3/Sym1.
1588 * tm-29k.h: Update BADMAG (though it should go away).
1589 Allow the register definitions to be overridden in another
1590 tm-file. Fix SR_REGNUM. Add a mess of _REGNUM's. Separate
1591 RETURN_REGNUM from GR96_REGNUM and DUMMY_SAVE_GREGS from
1592 DUMMY_SAVE_GR96, for handling kernel calling conventions
1593 that use GR64+ rather than GR96+.
1594 * tm-ultra3.h: New file, for use on Ultra3 Unix as well as for
1595 remote debugging of Ultra3 kernel. Includes tm-29k.h and
1596 overrides various things.
1598 * remote-mm.c (mm_attach, mm_wait): Handle attach like
1599 child_attach does, making a clean stop in the newly attached
1601 * remote-eb.c: Lint.
1603 * coffread.c: Make coffread independent of any particular
1604 variant of COFF. Avoid #include-ing any particular one except
1605 internalcoff.h. BFD now passes key values for symbol reading
1606 as part of its coff_data structure (LINESZ, SYMESZ, AUXESZ,
1607 and the symbol masks and shifts); use them.
1608 Remove obsolete end_of_text_addr.
1610 * exec.c: Remove unused include files.
1612 Wed Sep 11 19:38:44 1991 John Gilmore (gnu at cygint.cygnus.com)
1614 * Makefile.in (documentation targets): Pass $(M4).
1615 Bugfix from eggert@twinsun.com (Paul Eggert).
1617 * stack.c (down_silently_command): Check for stack existence.
1619 Tue Sep 10 23:08:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1621 * Makefile.in (VERSION): Update to 4.0.3.
1623 Tue Sep 10 09:19:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1625 * core.c (core_file_command): Print frame at coredump with
1626 its level number, by calling print_stack_frame.
1627 * frame.h: Add selected_frame_level, print_stack_frame.
1628 * frame.h, stack.c: Remove print_sel_frame, print_selected_frame.
1629 * convex-tdep.c, convex-xdep.c, infcmd.c, inflow.c, infrun.c:
1630 Change print_sel_frame and print_selected_frame callers to
1633 * dbxread.c (read_ofile_symtab): Avoid empty else clause.
1634 * symfile.c (free_named_symtabs): Ditto.
1635 * main.c (main): wrap_here needs an arg.
1636 * solib.c (find_solib): Avoid memory access if _DYNAMIC is zero.
1637 (solib_add): Avoid noise.
1638 (solib_create_inferior_hook): Lint.
1639 (sharedlibrary_command): Move dont_repeat to here.
1640 * utils.c (error): Call wrap_here to force buffered output.
1642 Small patches from Peter Schauer:
1644 * coffread.c (start_symtab): Free any existing line_vector before
1646 (read_coff_symtab): Ditto for type_vector.
1648 * source.c (lines_to_list): New variable, replacing function.
1649 (all uses): Use as variable.
1650 (_initialize_source): Add 'set listsize' and 'show listsize'.
1651 * utils.c (lines_to_list): Remove function.
1652 * stack.c (print_frame_info): Use as variable.
1653 * defs.h (lines_to_list): Remove declaration.
1655 Mon Sep 9 13:45:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1657 * breakpoint.c (insert_breakpoints): Restore warning about
1658 the program might be running in another process, but only for
1659 systems with this brain death (#ifdef ONE_PROCESS_WRITETEXT).
1660 * xm-hp300bsd.h, xm-mips.h, xm-vax.h: Define it.
1662 * utils.c (error): if error_pre_print is set, print the string
1664 * main.c (main, print_gnu_advertisement, print_gdb_version):
1665 Reformat legalese so it always prints, but acts as an "I'm here"
1666 message while symbols are being read. If any errors occur,
1667 print a few newlines to set off the message and start it at the
1668 left margin. Remove mention of "help" command, and don't yak
1669 about symbol reading.
1670 (catch_errors): Error string is now printed first in case of
1672 * command.c (undef_cmd_error, lookup_cmd): On undefined command,
1673 suggest the "help" command.
1675 * Makefile.in (VERSION): Set to 4.0.2.
1677 Thu Sep 5 23:49:48 1991 John Gilmore (gnu at cygint.cygnus.com)
1679 * .gdbinit: Remove useless "rr" command. Set complaints
1680 to 1 for people debugging gdb.
1682 * breakpoint.c, remote-vx.c: Reword strings printed by
1683 catch_errors callers.
1685 Wed Sep 4 11:07:50 1991 John Gilmore (gnu at cygint.cygnus.com)
1687 * WHATS.NEW: "history write -> history save". Doc "write on/off".
1688 (Fix from kenc@viewlogic.com.)
1690 Fix some infrastructure to be able to cope with host and target
1691 machines with different sized basic types (ints, ptrs, etc).
1692 (Idea from pierre@la.tce.com (Pierre Willard).)
1694 * values.c (value_from_longest): Rename from value_from_long.
1695 Handle pointer types as well as integers, so that targets with
1696 different pointer sizes from the host can be accomodated.
1697 * breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
1698 valarith.c, valops.c, valprint.c, value.h, values.c: Rename
1699 uses of value_from_long to value_from_longest.
1700 * eval.c, findvar.c, printcmd.c, valarith.c, valops.c: Pass
1701 the correct pointer type to value_from_long{est}.
1703 * doc/gdb.texinfo ($_, $__): Describe types of these variables.
1705 * remote-vx.c: Remove obsolete code for calling functions via
1706 vxworks kludge interface (it referenced value_from_long).
1708 * valops.c (value_string): Find malloc with lookup_misc_func, not
1711 Tue Sep 3 18:37:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1713 Make writing to files work properly. (Fixes to BFD are also needed.)
1715 * core.c (core_open): Open file ourselves, read or r/w, depending on
1716 write_files. Use bfd_fdopenr.
1717 * gdbcore.h (write_files): New variable.
1718 * exec.c (write_files): Define variable, add set&show for it.
1719 (exec_file_command): Use write_files to open for read or r/write.
1721 Make shared library reading happen automatically. These changes
1722 are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
1724 * inferior.h (stop_soon_quietly): Add to exported variables.
1725 * infrun.c (child_create_inferior): call solib hook, if defined.
1726 (child_attach): call solib hook, if defined.
1727 * solib.c: Include inferior.h. Add from_tty to so_list as kludge.
1728 (find_solib): Use lookup_misc_func rather than hand-rolled.
1729 (symbol_add_stub): New stub for catch_errors.
1730 (solib_add): Avoid output if !from_tty. Catch errors rather
1731 than just calling symbol_file_add and bombing.
1732 (solib_create_inferior_hook): Interface with the target process
1733 to let it read and alloc shared libs, then figure out what it did.
1735 * core.c (validate_files): Fix typo, soften warning.
1736 (Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
1738 * utils.c (fputs_demangled): Avoid duplicate printing if
1739 demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
1741 * infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
1742 (Fix from pierre@la.tce.com (Pierre Willard).)
1744 * main.c (catch_errors): Change argument to a char * from an int,
1745 since a char * can point to a struct full of glop, but an int
1746 is not guaranteed to be able to hold a pointer.
1747 * breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
1748 breakpoint_re_set_one, breakpoint_re_set): Adapt.
1749 * core.c (core_open, solib_add_stub): Adapt.
1750 * remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.
1752 Wed Aug 28 18:18:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1754 * Makefile.in: Update VERSION to 4.0.1. Evade GNU Make bug
1755 by adding .NOEXPORT target.
1757 Fri Aug 23 17:14:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1761 * Makefile.in (VERSION): Roll to 4.0.
1762 (gdb.tar.Z): Make refcard.ps as well, for shipment.
1764 Fri Aug 23 14:07:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1766 * doc/gdb.texinfo: minor rewordings, crossref to ptype from print,
1769 * doc/Makefile, Makefile.in: generate "gdb-all.texi" rather than
1772 * doc/rdl-apps.texi: renamed from rdl-apps.texinfo
1774 * Makefile.in, doc/Makefile, doc/.Sanitize, doc/gdb.texinfo:
1775 reflect above name change
1777 * WHATS.NEW: correct pointer to refcard.
1779 * doc/gdb.texinfo: update New Features, Installing
1781 * doc/gdbint.texinfo: add short description of configure +template
1783 Fri Aug 23 11:46:08 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1785 * doc/gdb.texinfo: update, fix bugs in "Installing" appendix
1787 Fri Aug 23 01:02:00 1991 John Gilmore (gnu at cygint.cygnus.com)
1789 * Makefile.in: Add config.sub, make doc/rdl-apps.texinfo for
1790 tar file, add dependencies for referenced doc files.
1792 Thu Aug 22 22:17:06 1991 Stu Grossman (grossman at cygint.cygnus.com)
1794 * coffread.c, symfile.c, stack.c: saberized.
1796 Thu Aug 22 16:20:27 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1798 * doc/refcard.tex: permuted Essential Commands sec
1800 * doc/gdb.texinfo: new C++ chapter; revised installation appendix;
1802 set/show symbol-reloading
1803 default set complaints 0
1805 RET-repeat disabled after prompted long displays
1806 processID (attach) interpretation of 2nd GDB cmdline arg
1808 Thu Aug 22 14:05:47 1991 Stu Grossman (grossman at cygint.cygnus.com)
1810 * expread.y, coffread.c, dbxread.c, target.c, mem-break.c,
1811 cplus-dem.c, values.c, valprint.c, symfile.c, remote.c,
1812 breakpoint.c, main.c: lint.
1814 Thu Aug 22 02:02:26 1991 John Gilmore (gnu at cygint.cygnus.com)
1816 Install new configuration scheme for GDB and friends.
1818 * config.sub: Translate ordinary names to three-part names.
1819 * configure: Use three-part names internally.
1820 * configure.in: Translate three-part names to filenames.
1822 * README, WHATS.NEW: Update for gdb-4.0.
1823 * Makefile.in: Roll VERSION to 3.99.
1825 Wed Aug 21 18:21:09 1991 John Gilmore (gnu at cygint.cygnus.com)
1827 * infptrace.c (KERNEL_U_ADDR_BSD): Include a.out.gnu.h.
1828 * i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
1829 tm-m68k.h, remote-nindy.c: Change ext_format_XXX structs
1830 to single structures rather than arrays; when passing
1831 their address, use &. This avoids trouble with bdead compilers.
1832 * mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
1833 instead. This avoids portability headaches.
1834 * mips-tdep.c (mips_do_registers_info): Only print FP regs if
1836 * source.c (open_source_file): Avoid ANSI const bdeath by
1837 skipping declaration and then casting result value.
1838 * tm-hp300bsd.h: Clarify comment.
1839 * utils.c (strstr): Result is const char *; ANSI bdeath.
1840 * xm-hp300bsd.h: Define HOST_BYTE_ORDER. Redefine INT_MIN,
1841 since system include file defines it differently from "defs.h",
1842 though the two are equivalent for our purposes.
1843 * tconfig/hp300bsd: Add m68k-tdep.o.
1845 Tue Aug 20 16:01:11 1991 John Gilmore (gnu at cygint.cygnus.com)
1847 * tconfig/sun*4: Remove warnings about system assembler.
1849 Mon Aug 19 13:44:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1851 * mcheck.c: Avoid warning about undeclared abort fn.
1852 * tm-sparc.h (PC_ADJUST): Avoid calling error() from this;
1853 it causes recursive calls to error() when used in cleanups.
1854 To do so requires that we make it a function, so we do.
1855 * sparc-tdep.c (sparc_pc_adjust): New implem of PC_ADJUST.
1856 * utils.c (do_cleanups): Remove the current cleanup from the
1857 chain *before* calling it, in case error() is called from it.
1858 The result won't be pretty, but won't be an infinite loop either.
1860 Mon Aug 19 00:41:04 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
1862 * dbxread.c (read_struct_type): Grok anon structs for C++.
1863 (vb_name, vptr_name): Null terminate these strings.
1865 Fri Aug 16 08:31:03 1991 John Gilmore (gnu at cygint.cygnus.com)
1867 Minor bug fixes from BSD Net2 gdb:
1869 * blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
1870 returns 0, there is no previous frame.
1871 * breakpoint.c (commands_command): If !from_tty, don't call
1872 input_from_terminal_p().
1873 * dbxread.c (record_misc_function): Speed up slightly.
1874 (compare_psymbols): Ditto.
1875 * infcmd.c (do_registers_info): Take a second argument to
1876 determine whether to print float registers. "info registers"
1877 does not do so anymore. "info all-registers" does, now.
1878 * mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
1880 * tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.
1881 * inflow.c (initialize_inflow): Set tflags_ours correctly.
1885 * breakpoint.c (bpstat_do_actions): Use a cleanup to restore
1886 executing_breakpoint_commands if we are interrupted by error.
1887 * coffread.c (init_lineno): Avoid problem with zero-sized linetab
1888 versus malloc/free. From: john@labtam.labtam.oz.au (John Carey).
1889 * core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a
1890 catch_errors() so we can setup the frame regardless of whether
1891 the shared libs work.
1892 * ieee-float.c (double_to_ieee_extended): Get exponent from
1893 right place in little-endian systems. From John Carey.
1895 Thu Aug 15 18:43:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1897 * main.c: Remove unused terminating_signals and catch_termination().
1898 (long_options): Terminate with a zero element.
1899 [Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
1900 (gdb_readline): Make call-compatible with readline.
1901 (init_signals): Improve comments re vfork vs. signal.
1903 * utils.c (prompt_for_continue): Use new gdb_readline().
1904 If we prompt for continuation, we don't let CR repeat the previous
1905 command, once we get back to a prompt. It's too easy to keep
1906 hitting CR, expecting "--more--" prompts, and have some long
1907 command start repeating on you.
1909 Tue Aug 13 16:17:56 1991 John Gilmore (gnu at cygint.cygnus.com)
1911 * blockframe.c (frameless_look_for_prologue): Speed up by
1912 calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
1913 * tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
1914 Define two variants, one faster.
1915 * sparc-tdep.c (sparc_frame_chain): Use target_read_memory
1916 and return zero, rather than giving an error.
1917 (setup_arbitrary_frame): Initialize the PC in the new frame.
1918 (skip_prologue): Add a second arg saying whether we're just
1919 checking for a frameless function or not.
1921 * core.c (core_open, core_close, core_xfer_memory): Move
1922 section table pointers and bfd* into the target_ops.
1923 (core_open): Allow errors in shared lib reading, etc.
1924 (core_files_info): Describe shared library sections.
1926 * exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
1927 exec_files_info, set_section_command): Move section table
1928 pointers and bfd* into the target_ops.
1929 (add_to_section_table): Add BFD to section table.
1931 * target.c (target_xfer_memory, target_info): Pass target to
1932 xfer_memory and target_info functions.
1935 * gdbcore.h: Move struct section_table.
1936 * target.h: New home of struct section_table.
1938 * solib.c (solib_add): New argument is the target_ops whose
1939 section list is to be added to, if any. Reallocate the
1940 sections in that target to add any that come from shared libs.
1941 (throughout) so_sections renamed to sections.
1942 (solib_xfer_memory): Deleted.
1943 * tm-sunos.h (SOLIB_ADD): Add target argument.
1944 (SOLIB_XFER_MEMORY): Delete.
1946 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
1947 remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
1948 from target_ops. It's the same on all targets. Add two section
1949 pointers to target_ops.
1951 * stack.c (find_relative_frame): Dump ancient algorithm for
1952 "down", just use handy "next" pointers.
1953 (frame_command): Don't error if there is no stack; let user
1956 * inflow.c (new_tty_prefork, new_tty): New prefork routine
1957 modifies static state in the parent process; new_tty itself
1958 runs in the child and modifies the child's file descriptors
1959 to match the saved static state.
1960 * infrun.c (child_create_inferior): Call new_tty_prefork,
1963 * infptrace.c (child_xfer_memory): Add ignored target arg.
1964 * remote-eb.c (eb_xfer_inferior_memory): ''
1965 * remote-nindy.c (nindy_xfer_inferior_memory): ''
1966 * remote-vx.c (vx_xfer_memory): ''
1967 * remote.c (remote_xfer_memory): ''. Rename from
1968 remote_xfer_inferior_memory.
1970 * main.c (main): Only try to attach "corefile" argument if
1971 it starts with a digit.
1973 * symfile.c (symbol_reloading): New "set/show" variable.
1974 (symbol_file_add): Shorten message about symbol reading.
1975 (add_symbol_file_command): Merge with add_syms_addr_command,
1976 since this should work on all targets now.
1977 (stop_whining): Default to zero, to shut up complaints
1978 about bad symbol tables on many systems.
1979 (free_named_symtabs): Just exit unless symbol_reloading.
1981 * xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
1982 and add comment explaining shared library screw.
1984 * source.c: #if defined => #ifdef.
1986 Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
1988 * doc/gdbint.texinfo: Improve doc on porting to new OS's.
1990 Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1992 * doc/rdl-apps.texinfo: provide default readline-appendix finder
1993 (doc/Makefile knows how to make one for local config)
1995 * Makefile.in: use doc/Makefile for doc targets
1997 * doc/Makefile: GDB documentation now has its own Makefile
1998 doc/refcard.tex: renamed from "gdbrc.tex"
1999 doc/.Sanitize: add Makefile; recognize renamed refcard.tex
2000 doc/gdbint.texinfo: add markup in "Cleanups" chapter
2003 Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2005 * values.c (baseclass_addr): When reading target memory, use the
2006 length of the basetype, not the upper type. We've only malloc'd
2007 enough space for the basetype, leading to errors in free().
2009 * expprint.c (print_subexp): Print UNOP_MEMVAL of an OP_LONG that
2010 ends up as a function specially, since we know the actual type of
2011 the pointed-to address. This (somewhat) fixes display of
2012 expressions that include misc_function_vector names. Try `cond 1
2013 !strcmp("a","b")' then `i b'.
2015 * infrun.c: Move DO_DEFERRED_STORES from proceed() to resume().
2016 The child can be proceeded from inside wait_for_inferior in
2017 evaluating breakpoint conditions, and DO_DEFERRED_STORES was
2018 getting skipped in that case.
2020 * expprint.c (print_subexp): Use filtered output, since the
2021 subroutines we call use it, otherwise the output is horribly
2022 mangled, since output of wrappable stuff comes out late.
2024 * Makefile.in: Bump VERSION to 3.98.1
2026 * infrun.c (child_create_process): Use execlp to find the
2027 shell to exec our target program. This requires some fiddling
2028 with `environ' since there is no execlpe().
2030 Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2032 * Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
2033 Minor rearrangement of refcard permits two new make targets--
2034 gdbrc.dvi DVI output for refcard, using CM fonts
2035 gdbrc.ps PostScript refcard, using PS fonts
2037 Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
2041 * TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
2042 * Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
2044 Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2046 * doc/gdb.texinfo: last changes for release.
2047 Minor typo and formatting fixes; incorporated most fixes remaining from
2048 filed mail commenting on earlier drafts.
2050 Added warnings: pipes don't work in run command;
2051 conditions are converse of assertions;
2052 step over fn without debug info goes to next fn;
2053 vars may have "wrong" values near fn entrance, exit
2055 Added example from Kingston on printing repeated nonadjacent values
2057 Added explicit mention that in Emacs gdb mode C-c and C-z are like
2058 shell mode for signals
2060 Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
2061 doesn't sound so much like its parent "Stopping and Continuing"; also
2062 moved entries on continue to top of section, so they don't get lost.
2064 Improved installation directions in appendix, added manual formatting
2067 Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
2069 * configure.in: Remove xm.h and tm.h even if we aren't linking
2070 new ones, so "./configure sun4; ./configure none" does the right
2071 thing. Assume that alldeps.mak and depend are already built in
2072 srcdir, and avoid running "make" (particularly "make depend",
2073 which involves "gcc") from inside configure. Build Makefile
2074 directly rather than building Makefile.conf first.
2075 * configure: Regenerate with above changes.
2076 * Makefile.in: Use $(BISON) to find bison. Roll VERSION
2077 to 3.98. Revise gdb.tar.Z procedure to produce a file
2078 called gdb-$(VERSION).tar.Z but which unpacks into a
2079 directory called "gdb". Move non-source files out of
2080 $(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
2081 (depend): Don't try to do "gcc expread.y".
2082 (expread.o): Update dependencies by hand.
2084 Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2087 Fixed a variety of small typos that prevented info from formatting
2088 cleanly; altered too-long heading for GPL Appendix, as discussed
2089 w/RMS; Changed date on cover to July 91.
2091 Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2094 (1) Applied some fixes due to comments from Larry Breed (easier ones
2095 through chapsec 5.2)
2096 (2) Eliminated use of @footnote---had my doubts about it anyways, and
2097 it's broken in latest texinfo
2098 (3) Introduced *some* use of [] for optional arguments, where
2099 explanation is not simpler by listing cmd w arg and cmd w/out arg
2100 separately. Still not using @deffn.
2101 (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
2102 couple of headings are too long. Need patches to texinfo or revision
2105 * Partial update to README (which still needs work for this
2106 release!): (1) use of configure corrected for new script,
2107 (2) "make gdb.dvi" and "make gdb.info" mentioned.
2109 Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
2111 * symtab.c (lookup_symbol): Don't complain right off about
2112 no debug symbols; use the misc function vector first.
2113 (list_symbols): Use misc function vector to find symbols
2114 that don't have debug info, and print them.
2115 (find_pc_symtab): Temporarily avoid fatal() when psymtab
2116 PC range doesn't match symtab PC range, as it does on the
2117 MIPS because our symtab reading isn't perfect.
2119 * dbxread.c (dbx_symfile_read): Make warning about
2120 "no debug symbols" slightly nicer.
2122 * source.c (select_source_symtab): If "main" symbol exists,
2123 but decode_line_spec can't find line info, don't just return
2124 a zero; try other source symtabs or give an error.
2126 * mipsread.c (parse_partial_symbols): Sort the psymtabs by
2127 their low addresses first, then rip through fixing high addrs.
2129 * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
2130 <runene@ifi.uio.no>.
2131 (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
2133 Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2135 * Minor, mostly mechanical, cleanup of doc subdir for clean
2136 makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
2137 and gdb.info (post- texinfo2 makeinfo) generated for distribution.
2139 Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
2141 Mostly MIPS and general symbol-reading fixups.
2143 * doc/gdbint.texinfo: Add documentation on symbol-reading
2146 * mipsread.c: Remove kludges around #include "ecoff.h".
2147 Remove redefinitions of a_magic, etc, no longer used.
2148 (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
2149 Fix global overview comments to match symfile.c protocol.
2150 (mipscoff_new_init): Eliminate cur_hdr if we have one.
2151 (mipscoff_symfile_read): Eliminate unused code. Avoid
2152 sorting all the symtabs, when all we have read here is psymtabs.
2153 The symtabs are sorted as they are created anyway. Tell
2154 condense_misc_bunches whether we're mainline.
2155 (psymtab_to_symtab_1): Pass filename when recursing, to make
2156 stack trace more informative.
2157 (parse_partial_symbols): Assume cur_hdr as argument.
2158 (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
2159 Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
2160 the TYPE_NAME of char *, since that's done in symfile.c.
2161 (free_numargs, parse_symbol, add_symbol, add_block,
2162 shrink_linetable): Declare these fns void.
2163 (upgrade_type): Convert tree of if's to switch. Clean up
2164 bogus "off == 0" handling with a complaint. Avoid setting
2165 field bitpos and bitsize of array with lower and upper bounds.
2166 Check specified bitsize of elements against their actual type's
2167 bitsize, and complain if different. Complain about unknown
2169 (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
2170 (psymtab_to_symtab_1): Print names of subsidiary files that
2171 are being read in. FIXME, we read far too many files. This code
2172 is not the problem, the problem is in parse_fdr where the psymtabs
2174 (cross_ref): Result should indicate that we used one aux entry
2175 normally, or two if we encountered a "next" entry. This used
2176 to leave the caller pointing at the wrong aux entry.
2177 (add_symbol): If overflowed cur_block, reallocate it larger,
2178 chase all pointers to it, and complain(), rather than clobber memory.
2179 (shrink_block): Use xrealloc rather than xmalloc-and-copy.
2180 (new_field): Only allocate one field initially, not two.
2181 Pull ++ out of macro argument. Simplify.
2182 (_initialize_mipsread): Avoid initialization of importd
2183 global_psymbols and static_psymbols.
2185 * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
2186 to properly set pst->symtab; avoid searching for it.
2187 (symfile_fns): Improve comments, add a FIXME.
2188 * dbxread.c: Update comments to reflect symfile protocol.
2189 (read_ofile_symtab, end_symtab): Return the symtab.
2190 (psymtab_to_symtab_1): Set pst->symtab.
2192 * coffread.c (coff_symfile_read): tell condense_misc_bunches
2193 whether we're mainline.
2195 * symfile.h (sym_fns): Remove unused sym_discard member.
2196 * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
2198 * mtrace.c (mtrace): Take effect if mallwatch is set, even if
2199 the environment variable is not.
2200 * infcmd.c (finish_command): Use filtered printfs.
2201 * cplus-dem.c: Add struct tags to a few unnamed structs.
2202 * valops.c (value_coerce_array): Improve comments.
2203 * valprint.c (type_print_varspec_suffix): Print array size only
2204 if greater than zero.
2205 * m88k-tdep.c: Shift some lines left by one space, that had
2206 apparently been trashed at some point.
2207 * TODO: More things to do, a few got done.
2209 Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
2211 * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
2212 (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
2214 * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
2215 * expread.y, findvar.c, symmisc.c: Ditto.
2216 * printcmd.c (address_info): Update printed forms of LOC_
2217 symbols. Elim LOC_EXTERNAL.
2218 (print_frame_args): Keep track of param stack offsets before
2219 re-looking up to find the local register param is kept in.
2221 * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
2222 Further integration of mipsread into gdb. Eliminate unused
2223 routines, duplicate declarations. Handle static symbols in
2224 psymtabs as well as external symbols. When reading symtabs,
2225 insert symbols into the correct block (global, static, or a local
2227 (read_mips_symtab, parse_partial_symbols): Don't pass useless
2229 (mipscoff_symfile_read): Don't call select_source_symtab.
2230 (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
2231 rather than SYMBOL_VALUE.
2232 (parse_external): Comment clobbering of top_stack.
2233 (parse_partial_symbols): Update comments. Allocate and parse
2234 static symbols as well as external symbols. FIXME, enum values
2235 are not handled in this pass, but should be. Inline new_psymbol.
2236 Use SYMBOL_VALUE_ADDRESS.
2237 (psymtab_to_symtab_1): Read symbols into global static block
2238 by default (until enter some function's local block context).
2239 (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
2240 (destroy_all_symtabs, new_psymbol): Eliminate, unused.
2242 * source.c (select_source_symtab): Select a source symtab
2243 from either the symtabs or, failing that, the psymtabs.
2244 (list_command): Update error message.
2245 (forward_search_command, reverse_search_command): Use getc, not
2246 fgetc, for speed. FIXME, add comment about buffers that die if
2247 overrun by long line.
2249 * values.c (unpack_field_as_long, modify_field): Avoid shifting
2250 by an entire word, which is not portable, if we have a 32-bit
2251 field. (Code in dbxread.c already turns such bitfields, if
2252 aligned, into ordinary ints, but fixing this will help for other
2253 symbol formats and for future changes.)
2254 * core.c (core_open): Handle ANSI const brain death.
2255 * utils.c (vprintf): Fix varargs typo.
2257 Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
2259 * findvar.c (find_var_value): Handle &function better.
2260 * TODO: Document work needed on &fn and &array.
2261 * printcmd.c (print_address_symbolic): New arg is the prefix
2262 to print if a name is printed.
2263 (print_address_demangle): Honor "set print address" now.
2264 Use new arg above to improve spacing of output.
2265 * valprint.c (val_print): When printing function pointers,
2266 print symbolic form too.
2267 * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
2269 Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2271 * core.c (memory_error): Reword error msg to mislead less.
2273 * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
2275 * mipsread.c (read_mips_symtab, read_the_mips_symtab,
2276 parse_partial_symbols): Use newer BFD internals (external_filehdr
2277 and external_aouthdr), byte-swap the fields that we care about
2278 before using them, and make the file header data local to
2279 read_the_mips_symtab rather than global.
2281 Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
2283 * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
2284 from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
2286 * main.c (command_line_input): Flush stdout and stderr
2287 before every call to readline. This reportedly fixes a bug
2288 that comes up in Sys V running emacs-gdb and/or xxgdb,
2289 when stdin/out are pipes or sockets.
2291 Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2293 * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
2294 Avoid declaring Makefile dependencies, because GNU Make stupidly
2295 tries to update it if we do.
2297 * coffread.c: Revise for minor changes to bfd internal coff
2300 * configure: If -template= is given a relative path, make it
2301 absolute before recurring in subdirectories.
2303 * configure, configure.in, Makefile.in: Install "configure" script
2304 as replacement for config.gdb.
2305 * config.gdb, Makefile.dist, Makefile.sdir: Remove
2306 * README: Update for configure, mostly. FIXME.
2308 * Add dec3100 as equivalent to littlemips. Indicate in all host &
2309 target config files that they are for the host. When the lines
2310 get copied into the Makefile, this makes it more obvious what's
2313 Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2315 * sparc-opcode.h (trap opcodes): Avoid leading spaces or
2316 tabs, which end up in the disassembler output inadvertently.
2318 Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
2320 Make it compile cleanly in an ANSI GCC2 environment.
2322 * blockframe.c: <stdio.h>
2323 * cplus-dem.c: free takes a void *, ifdef __STDC__
2324 * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
2326 * defs.h (alloca): Avoid doing anything if alloca already def'd.
2327 * stddef.h, stdlib.h: Remove these files.
2328 * symtab.c: Avoid declaring qsort, close.
2329 * symfile.c: Avoid declaring close.
2330 * utils.c (vprintf): Declare "ap" arg as proper va_alist.
2331 * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
2333 Assorted other changes.
2334 * dbxread.c: include "libaout.h", not "liba.out.h".
2335 * printcmd.c (print_frame_args): Set recurse properly for
2336 indentation of struct and array parameters.
2337 * valops.c (value_cast): Allow cast to void.
2338 * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
2339 single_step() in a target-independent fashion.
2340 * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
2341 set up to be ready to continue. This makes us target independent.
2342 * infptrace.c (child_resume): Remove call to single_step; now
2343 can single step a SPARC target of any kind.
2345 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2347 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
2348 docn into separate sections---basically chapters, plus two loose
2349 pieces that can be configured to go in different places. This
2350 allows GNU m4 to preprocess the manual without coredumping.
2352 * Makefile.dist: tell TeX where to find texinfo.
2354 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2356 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
2357 the new target "rdl-apps.texinfo" which captures the Makefile
2358 variable that records where to find the Readline libraries.
2360 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
2362 * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".
2363 * tm-tahoe.h (FIX_CALL_DUMMY): Ignore more parameters.
2364 * defs.h (const, volatile): Only define if not already defined.
2365 * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
2367 * README: Update for release 3.95.
2368 * config.gdb: Don't create readline dir in subdir builds.
2369 * main.c: Include with "..." form for non-system include files,
2370 so "gcc -MM" for "make depend" works.
2371 Include readline files with "...h" rather than <readline/...h>.
2372 * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
2374 * coffread.c: Undo minor damage done by Rich Pixley. Use
2375 different internal and external representations of COFF
2376 data structures. Use new BFD routines for swapping them in and
2378 * symfile.c (free_named_symtabs): Avoid freeing file names that
2379 are null or empty. Old i960 tools seem to produce files that
2380 claim to have empty names, causing each successive file read
2381 to blow away the previous one.
2382 * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
2383 Move deferred_stores to top of file, but don't separate its
2384 #define's from its variable. Add commentary.
2385 * Makefile.dist: Fix Rich damage; undo "configure" changes in
2386 favor of keeping the (working) config.gdb. Move readline
2389 Fri May 17 12:49:56 1991 Per Bothner (via gnu at cygint.cygnus.com)
2391 * dbxread.c (read_struct_type): Try to handle g++ version 1 MI
2393 * infptrace.c (fetch_registers): no result, since now void.
2394 * tconfig/news: target depends on m68k-tdep too.
2396 Fri May 17 14:40:14 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2398 * Makefile.dist: added readline/inc-*.texinfo to dependencies for
2401 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
2402 applied various small fixes due to or inspired by RMS comments
2404 * doc/gdb.texinfo: finished using all RMS comments, save those for
2405 appendices on readline and cmd history (which are in other source
2408 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2410 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
2411 chapter 9; (2) documented 'break' command's menu mode for
2412 overloaded names, in response to hgs problem report C++ p-31
2414 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2416 * doc/gdb.texinfo: (1) better introductory example; (2) more
2417 consistent use of @code, @samp, @file, @kbd throughout; small
2418 cleanups to first three nodes; (3) new "Contributors" node;
2419 (4) Appendix, Renamed Commands; (5) divert specialized startup
2420 instructions to "Targets" chapter for generic manuals, while
2421 leaving them up front for manuals specific to specialized
2422 environments; (6) apply fixes from RMS comments through chapter 4.
2424 * pretex.m4: modify explanatory text slightly (and redefine
2425 "regexp") to keep GNU m4 from complaining. (It still crashes

2437 * Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
2438 stuff for config manual) here where it counts; updated
2439 to use new subdir structure (gdb/doc/).
2441 * Makefile: generated from above via
2445 * gdbint.texinfo: added instructions on generating gdb.info* files
2446 locally for release. These are ordinary info
2447 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
2448 Makefile)---but due to use of texinfo 2, can't count on makeinfo
2449 to generate these, so we distribute them already formatted.
2451 * gdb.texinfo: included full Info node and menu crud (as generated
2452 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
2454 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
2455 put in comments-for-future gdb.info target (one day makeinfo will

2463 set, info source, info terminal, info types, info user, set/show
2465 Also covered all recent GDB command renames for v4.
2467 Mon May 13 14:57:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2469 * mipsread.c: Rather than keeping count of how many symtabs
2470 and psymtabs we have, for sorting purposes, count them when
2471 we need to sort. This fixes bug in rereading of symbol tables.

2497 * remote.c: Remove decls of memory_insert_breakpoint
2498 and memory_remove_breakpoint, no longer used. (Suggestion of
2501 * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
2502 to make it easier to interface to "configure"'d libraries.
2504 Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
2506 * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as

2898 before returning locals or slocals.
2900 * i386-tdep.c (i386_follow_jump): Do not add data16 to pos in
2901 call to codestream_seek; add one to pos if (and only if)
2902 we are dealing with a jump with data16 == 1 (i.e. 0x66, 0xe9).

2932 tm-sun3.h: Define TARGET_SUN3.
2934 * utils.c: Use CPLUS_MARKER not '$'.
2936 * cplus-dem.c: Use CPLUS_MARKER not '$'. If CPLUS_MARKER isn't
2937 defined, define it to '$'.
2939 * arm-opcode.h: New file (same contents as before; it had
2940 just been left out of the distribution for a long time).
2942 * tm-68k.h: Put declaration of ext_format_68881 outside the macros.
2944 * main.c: New HAVE_SIGSETMASK #ifdefs.

3010 * inftarg.c (child_open), remote-vx{,.68}.c (vx_proc_open):
3011 New function to give correct error message.
3013 Thu Apr 11 17:19:41 1991 Jim Kingdon (kingdon at cygint.cygnus.com)
3015 * target.h: Add to_doc and target_preopen.
3016 target.c: Add target_preopen and target_command.
3018 (add_target): Call add_cmd and mess with targetlist->doc.
3019 core.c, exec.c, remote-eb.c, remote-nindy.c, remote-vx.c,
3020 remote-vx.68.c, inftarg.c, remote.c: Add doc field to target struct.
3021 Call target_preopen from open routine.
3023 * main.c: Rename editing_info to show_commands.

3040 Thu Apr 18 18:08:30 1991 John Gilmore (gnu at cygint.cygnus.com)
3042 * symfile.h (free_named_symtabs): Rename from free_named_symtab.
3043 * symfile.c (clear_symtab_users_once, cashier_psymtab,
3044 free_named_symtabs): Move these routines from symmisc.c.
3045 * symmisc.c (same): same.
3046 (free_symtab): Make non-static.
3047 * symtab.h (free_symtab): Declare as exported void fn now.
3048 * dbxread.c (end_symtab, end_psymtab): Change comments.
3049 (initialize_dbxread): Call dbx_new_init() in case the first
3050 command is add-symbols.
3051 * target.c (dummy_target): Permit add_syms_addr_command.
3053 Sat Apr 13 14:46:07 1991 John Gilmore (gnu at cygint.cygnus.com)
3055 Permit symbols to be superseded when new symbol files have
3056 been read in, particularly for VxWorks.
3058 * dbxread.c (read_dbx_symtab): Allow N_SOL to cleanly take us back
3059 to the main file, as well as to include files. Also, put global
3060 functions into the global psymtab, to make "i fun" work.
3061 (end_psymtab): Free named symtabs and psymtabs for a file, once a
3062 new psymtab for it has been read.
3063 * coffread.c (end_psymtab): Free named symtabs and psymtabs for
3064 a file, once a new symtab has been read for it.
3065 * mipsread.c: FIXME. We need to do the same for MIPS, but it
3066 looks harder to determine the top-level block before it's been
3067 queued to the psymtab list.
3069 * symfile.c (symbol_file_add): Use filtered printing and wrap it.
3070 If we have wiped out any old symbol tables, clean up at end of
3072 (symbol_file_command): Don't reference symfile_fns if it's zero.
3074 * symtab.h (GLOBAL_BLOCK, STATIC_BLOCK, FIRST_LOCAL_BLOCK): New
3075 defines for the blocks of a blockvector that contain global and
3076 file-static symbols and the first of the smaller scope contours.
3077 * symtab.c (lookup_symbol, find_pc_symtab, find_pc_line,
3078 decode_line_1, make_symbol_completion_list): Use the above.
3079 * coffread.c (end_symtab, patch_opaque_types): Ditto.
3080 * dbxread.c (end_symtab): Ditto.
3081 * expread.y (block): Ditto.
3082 * mipsread.c (throughout): Ditto.
3083 * symmisc.c (free_named_symtabs): Ditto.
3085 * symtab.c (list_symbols): Process the first symbol of the
3086 static psymbols list.
3087 (types_info): Restore this function from its untimely #if 0.
3088 It's not perfect, but it is better than nothing.
3089 (_initialize_symtab): Restore "info types".
3091 Thu Apr 11 05:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
3093 * m68k-stub.c: Remote stub for 680x0's, created from
3094 rem-m68k.shar (which is removed).
3095 * nindy-share/{Makefile,Onindy.c,blout.h,env.h,nindy.c,ttyflush.c}:
3096 Remove RCS log stuff now that we use CVS and it blows our diffs.
3098 Wed Apr 10 14:18:06 1991 John Gilmore (gnu at cygint.cygnus.com)
3100 * symmisc.c (free_named_symtab): Make it work, in its current
3101 kludgy fashion. Change result to indicate if we blew away bkpts.
3102 * dbxread.c (end_symtab): Accumulate result from
3103 free_named_symtab and print warning if we blew user's state.
3104 * symfile.h: free_named_symtab now returns an int.
3106 Mon Apr 8 23:57:43 1991 John Gilmore (gnu at cygint.cygnus.com)
3108 * dbxread.c (dbx_symfile_read): Initialize psymbol list if this
3109 is the first symbol read, even if not mainline.
3110 (dbx_psymtab_to_symtab): symfile might be zero, cope.
3111 * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
3112 (set_section_command): New command ("section xxx yyy" -- should
3113 be renamed to "set section xxx yyy" FIXME) which sets the
3114 base address of a section of the exec file, overriding the
3115 virtual address that BFD reports.
3117 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
3119 * exec.c: Add add_syms_addr_command to exec_ops, so you can
3120 load symbols at any address while examining an exec file.
3122 Thu Apr 4 10:09:35 1991 John Gilmore (gnu at cygint.cygnus.com)
3124 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
3125 for printing the float info is host-dependent, not
3126 target-dependent. FIXME.
3127 * i386-pinsn.c: Move #includes to top, remove useless ones.
3128 * i386-tdep.c: Don't bother including <.../reg.h> since we
3129 don't use it (and it doesn't exist on host systems).
3131 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
3132 Convert negative numbers properly.
3133 (ieee_test): Make numbers really random; fix format arg.
3135 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
3136 * core.c (core_detach): Unpush core_ops, which might not be on
3137 top. We used to just pop the top, which broke things. Don't
3138 need dont_repeat() any more.
3139 (core_file_command): Psst! Don't repeat it.
3140 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
3141 * expprint.c (print_subexp): Avoid switch fallthru on
3142 BINOP_ASSIGN_MODIFY, so we can print += and such.
3143 * frame.h: Fix typo.
3144 * inflow.c (kill_command): After killing inferior, print our
3145 current frame in the core file, if we have one.
3146 (generic_mourn_inferior): When inferior dies, either select
3147 the current frame (in the new target, e.g. core file), or
3148 set both the current and selected frames to NULL.
3150 Changes from Peter Schauer.
3152 * infptrace.c: Avoid <sys/ptrace.h> on USG.
3154 * Make all file names fit in 14 characters (sigh and damn!):
3155 mv hp300hpux-xdep.c hp300ux-xdep.c
3156 mv symmetry-xdep.c symm-xdep.c
3157 mv symmetry-tdep.c symm-tdep.c
3158 mv convex-opcode.h convx-opcode.h
3159 mv tm-vxworks960.h tm-vx960.h
3160 mv tm-vxworks68.h tm-vx68.h
3161 mv Makefile.srcdir Makefile.sdir
3162 mv gdb-int.texinfo gdbint.texinfo
3163 mv remote-sa.m68k.shar rem-m68k.shar
3164 mv remote-multi.shar rem-multi.shar
3165 * Makefile.dist, README, config.gdb, convex-pinsn.c,
3166 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
3167 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
3170 * command.c (user_info_1, user_info): New command for listing
3171 the user-defined commands.
3173 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
3175 * dbxread.c (really_free_pendings): Clear file_symbols
3176 and global_symbols after freeing them; otherwise, running
3177 this function twice (if it appears twice on the cleanup
3178 chain), we try to free things twice.
3180 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
3181 based on text_addr (the address of text in core), not on addr (the
3182 offset between text in the .o file and in core). This change
3183 is from Peter Schauer.
3185 * main.c: Define ALL_CLEANUPS as a cast of zero.
3186 (return_to_top_level): Use it.
3187 (main): Do all cleanups after each command run as part
3188 of the gdb startup sequence. Also do all cleanups before
3189 entering the command loop, and every time we exit the command
3190 loop and reenter. Before, the cleanups from the startup sequence
3191 were being left undone until the first error!
3192 (command_loop): Rename do_nothing cleanup to command_loop_marker
3193 so we can see it easily when examining the cleanup chain.
3194 (init_signals): Add another do_nothing for signal handling.
3195 (quit_command): Only try to kill target if it has execution.
3196 Problems in the target stack got us into a state where
3197 inferior_pid was nonzero but none of the targets had execution.
3198 In this state you couldn't exit gdb.
3200 * dbxread.c: Two changes from Peter Schauer.
3201 (echo_command): Fflush output after an echo command.
3202 (show_history): Pass all args to cmd_show_list.
3204 * utils.c (init_malloc): Call mtrace to turn on tracing
3205 if the environment variable MALLOC_TRACE is set to a file name.
3206 * mtrace.c: Add source file which provides a log of every malloc,
3207 free, and realloc to a trace file.
3208 * mtrace.awk: Add source file which analyzes the trace file.
3209 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
3210 (VERSION): Roll to 3.94.3.
3212 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
3213 (check_duplicates): Don't bother with watchpoints.
3214 (set_raw_breakpoint): Comment about danger of this routine.
3215 (watch_command): Parse and eval all args before calling
3218 * solib.c (find_solib): Avoid error in referencing memory to
3219 see if any more shared libraries have been added. This is
3220 particularly useful if the target has terminated. Bug reported
3223 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
3224 in bringing up 3.94.2 on the Sun-3.
3226 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
3227 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
3228 expression (in scope) before reenabling watchpoint.
3229 * signame.c (init_sigs): Add missing declaration of i, fix
3230 sys_siglist declaration.
3231 * source.c (list_command): Fixed range computation to use
3233 * stack.c (backtrace_command): Do not allow command if target has
3234 no stack, print informative error message.
3235 * target.c (target_command): Do not write into command line
3236 because this fails if the target command is used in a user defined
3237 command. [This change was enhanced by gnu to support any-
3238 unique-prefix matching on target names.]
3239 * valops.c (value_struct_elt): Avoid infinite loop on an
3240 erroneous attempt to print the member of function (try p main.p).
3242 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
3244 * expread.y (name_no_typename): Avoid reduce/reduce errors
3245 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
3246 Since the GDB parser really doesn't use name_no_typename in a
3247 name-only context, the parser can't tell the diff between
3248 names and numbers here. Avoid allowing a name_no_typename
3249 to be a NAME_OR_*INT to resolve the conflict.
3251 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
3253 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
3255 * valprint.c (val_print_fields): bitfield printing didn't handle
3256 byte order. Indirect through a few more fns to cope.
3258 * values.c (modify_field): also cope with byte order.
3260 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
3262 Cleanup for release 3.94.2:
3264 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
3265 include files. Roll version to 3.94.2.
3267 * coffread.c (init_stringtab): Read length into unsigned char
3268 array before swapping; don't assume 32-bit longs.
3270 * target.c (target_info): Don't bother with get_sym_file, just use
3271 the symfile global variable.
3272 * symtab.h, symfile.c (get_sym_file): Delete it.
3274 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
3275 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
3276 (read_type): Replace one more error() with complain().
3278 * mipsread.c (parse_partial_symbols): Replace printf with complain.
3280 * i960-tdep.c: Fix copyright attribution.
3282 * config.gdb: Quote all backquotes in doublequotes. You can
3283 quote me on that. BSD 4.4 shell found this one.
3285 * infptrace.c (throughout): The third argument to ptrace is an
3288 * infrun.c (wait_for_inferior): When program has terminated, we
3289 have to call target_terminal_ours before we pop that target off
3290 the stack (e.g. before a call to target_kill or
3291 target_mourn_inferior). This fixes problem where a program
3292 terminates, then GDB stops for (tty output) and you have to type
3293 "fg" to the shell to resume it. FIXME: This code for what to
3294 do after termination really should be in normal_stop instead.
3296 * gdbcore.h (read_memory_check): Change declaration; it changed
3299 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
3300 4.4 prereleases, this avoids a bug in their sgtty compatability
3302 * remote.c: Use terminal.h rather than hand-rolling the same.
3304 * signame.c, signame.h (psignal): Arg is unsigned, not int.
3305 * utils.c (strsave, strstr): Fix arg types.
3306 * valprint.c (val_print): lint
3308 MIPS symbol table support from Per Bothner:
3310 * symfile.c (symtab_fns): Remove initializer table that needs to
3311 be hacked for each new symbol file format supported.
3312 (add_symtab_fns): New function, chains symbol table
3313 handlers into the global list.
3314 (symfile_init): Search this list.
3315 * symfile.h: Add next pointer, declare add_symtab_fns.
3316 * coffread.c (_initialize_coffread): Call add_symtab_fns.
3317 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
3319 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
3320 symbol *). Thus, we no longer need the hack to trash
3321 pst->filename. Good, since that hack confused code in symfile.c!
3323 (reorder_symtabs, destroy_all_symtabs): Removed static
3324 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
3325 Instead, the latter now uses a temporary array (stack-allocated
3326 from an obstack, and then freed).
3328 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
3329 haven't been set in the outermost stBlock of a procedure. This was
3330 a problem with f77 binaries on Ultrix 4.?.
3332 (new_symtab, new_symbol, new_type): Continue changing code to use
3333 obstacks more and otherwise conform to dbxread internal style.
3334 Made the free_code of symtabs be free_linetable (as in dbxread)
3335 instead of free_contents. This implies memory leaks when reading
3336 a new symbol table, until the conversion is finished. Did change
3337 (struct symbol) and (struct type) to be allocated on the
3338 symbol_obstack. Blocks and blockvectors are among the things
3341 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
3342 tested much, but it solved one problem (reported by Meissner), and
3343 cleans up some other things. The problem happened when an
3344 included file contains actual code (functions) and not just
3345 definitions. The mips coff is a little inconvenient there, since
3346 it may cause a procedure to be mapped to the wrong psymtab.
3348 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
3349 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
3350 this will need work for the new core paradigm.
3352 Opcode patches from the net:
3354 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
3355 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
3356 missing altogether - they are added here. From Bruce Bauman.
3357 * mips-opcode.h: The low mask for C0 instructions was too small.
3358 From Garrett Lau. I modified the fix to check the entire 32-bit
3361 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
3364 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3366 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
3368 * dbxread.c (read_type): Pointer subtraction (value_sub in
3369 valarith.c) sometimes failed because the types of the
3370 pointers being subtracted were not identical.
3371 These differed because dbxread.c was allocating pointer types
3372 using dbx_alloc_type+smash_to_pointer_type instead of
3373 lookup_pointer_type. I failed to find a justification for the
3374 former, so I changed it to use the latter. Similarly, I
3375 replaced smash_to_function_type by lookup_function_type,
3376 and smash_to_reference_type by lookup_reference_type.
3378 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
3379 _initialize_mipsread): corresponding changes.
3381 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
3383 * source.c (mod_path): Do tilde_expand on each component of the path,
3384 rather than on the (list of) paths as a whole.
3385 (print_source_lines): Set first_line_listed in addition to
3386 current_source_symtab and current_source_line. If the source was
3387 not findable, after a "dir" command to fix the problem,
3388 a "list" would get the wrong lines.
3390 While I was there... (gnu):
3392 * dbxread.c (read_type): Change error to complaint.
3394 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3396 First attempt at detailed understanding of symbol table memory alloc.
3398 * dbxread.c (dbx_symfile_read): Free our string table if we
3399 aren't the mainline. Free the "info" struct since we're done with
3401 (init_psymbol_list): Free any previously allocated psymbol lists.
3402 (): FIXME: Should realloc-down the psymbol lists when done reading
3403 the main symbol file?
3405 * symmisc.c (free_symtab): Free fullname field too.
3407 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
3408 (REGISTER_ADDR): Make result type unsigned int.
3410 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
3411 define REGEX must also define REGEX1 (its dependency).
3413 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
3415 * tconfig/i960: No longer works, points you at vxworks960 or
3418 * xgdb.c, XGDB-README: Remove file. Users can get the much
3420 * Makefile.dist: Remove all trace of xgdb.
3422 * breakpoint.c (breakpoint_1): Pass demangle arg to
3423 print_address_symbolic.
3424 (clear_breakpoints): Remove unused function.
3425 (breakpoint_re_set_one): Guts of breakpoint_re_set.
3426 (breakpoint_re_set): Use catch_errors to do them all anyway.
3428 * gdb-int.texinfo (Host versus Target): Add section on what is
3429 a "host" feature versus what is a "target" feature.
3431 * infcmd.c (path_command, path_info): Handle the PATH variable
3432 (object search path) as conveniently as the source search path.
3433 * environ.c (set_in_environ): Set some vars in GDB's environment,
3434 in addition to the child's. PATH, G960BASE, G960BIN for starters.
3435 * source.c (mod_path): New function, from guts of
3436 directory_command, modifies a path. Used by path_command.
3437 (directory_command): Call it.
3438 * defs.h (strsave): Declare.
3440 * utils.c (sevenbit_strings): Add new printing option.
3441 (printchar): Use it.
3442 (strsave): Provide this handy helper routine.
3443 (set_width_command): Rename set_screen_width_command.
3444 (_initialize_utils): "set screen-width" => "set width";
3445 "set screen-height" => "set height"; add sevenbit-strings.
3447 * infcmd.c (do_registers_info): Print floating point registers
3448 in raw hex as well as float format, regardless of whether it is
3449 a "virtual" convertible register.
3450 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
3451 regs as a double, just in case it's being used that way.
3452 * values.c (unpack_long): Comment on array/function coercion.
3453 (unpack_double): Argument is in target byte order now. For
3454 integer arguments, just call unpack_long and float the result.
3455 * m68k-tdep.c: include defs.h for "const" handling.
3456 * remote-nindy.c: Use ieee-float stuff.
3457 (nindy_fetch_registers): Unpack double regs to host double, then
3459 (nindy_store_registers): Pack extendeds to host double, flip
3460 around by misusing unpack_double, send as target double.
3462 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
3463 zero, as when stopped at the first instruction of a process.
3465 * blockframe.c: Fix filename in comment (param.h => tm.h).
3466 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
3467 * tm-68k.h: Fix typos.
3469 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
3471 Changes from a bringup on the DEC Vax under Ultrix 4.0.
3473 * coredep.c (fetch_core_registers): Pass end-address of register
3474 section to register_addr as expected. Don't call supply_register
3475 if we'd just pass it garbage.
3477 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
3479 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
3481 * target.c (push_target, target_info): Cast enums to int for < or
3484 * stack.c (print_frame_info): Identify source file & line
3485 even if we can't print it.
3487 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
3489 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
3491 Clean up IEEE floating point support.
3493 * ieee-float.h: New file.

3498 sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
3499 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
3500 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
3501 double_to_ieee_extended.
3502 * i960-tdep.c: Define ext_format_i960.
3503 * m68k-tdep.c: Define ext_format_68881.
3504 * sparc-tdep.c: Define ext_format_sparc, though unused.
3505 * Makefile.dist (HFILES): Add ieee-float.h.
3506 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT

3512 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
3513 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
3514 * tconfig/nindy960: Remove reference to coffstrip.o.
3516 * Makefile.dist: Roll version number to 3.94.1 (not yet final).

3521 * dbxread.c: Remove static symfile_bfd.
3522 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
3524 * inftarg.c (child_detach): Pop the child_ops vector if the
3525 detach is successful.
3526 * remote-nindy.c (nindy_create_inferior): Don't push a new
3527 nindy_ops since nindy uses the same one for execution and memory
3529 * core.c (core_ops): Use child_attach and child_create_inferior
3530 rather than default attach and create_inferior functions.
3532 Handle floating point registers in core files.
3534 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
3535 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
3536 This version untested since BFD doesn't yet support sun3 core
3538 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
3539 conventions. Fix comments and style. This version has not
3540 been compiled yet, since we have no HP inhouse.
3541 * core.c (get_core_registers): Look for two sections, ".reg"
3542 and ".reg2", and pass both to fetch_core_registers sequentially.
3544 Revise directory path yet again.
3546 * source.c (forget_cached_source_info): Not static any more.
3547 (init_source_path): New default source path is "$cdir:$cwd".
3548 (dir_command): Handle variable arguments ($cdir, $cwd).
3549 (source_info): Print "Compilation directory" rather than
3550 "Originally compiled in" to remind people of $cdir.
3551 (openp): If the path contains $cwd, use current directory.
3552 (open_source_file): If compilation directory is known, replace
3553 first $cdir in path with the compilation directory.
3554 (print_source_lines): Even if we can't print the lines, set the
3555 current symtab and line for future commands like "info source" or
3556 "breakpoint". Also, error message now contains the file name,
3557 line number, and file access error message.
3558 (_initialize_source): Fix help text to describe changes.
3559 * main.c (cd_command): Forget cached source info when we chdir.
3560 * utils.c (strstr): Add simple implementation.

3564 * coffread.c (read_one_sym, init_linetable, init_stringtab):
3565 Byte-swap COFF symbol tables if necessary when reading them in.
3566 Use complain() to replace error message in one spot. Needs
3567 corresponding change in bfd/coff-code.h to make some symbol
3568 swapping routines non-static.
3570 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)

3580 declarations of errno.
3582 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
3584 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
3585 <rpc/rpc.h> and <rpc/types.h>.
3587 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
3589 * i960-tdep.c (examine_prologue): Add new argument limit,
3590 which stops the scan at the end of the prologue, or at the PC.
3591 This fixes a problem where it walks down into the code for the
3592 user's statements if that code looks like function prologues.
3593 Mark Fox and I have been bouncing this code back and forth, making
3594 small changes to it. Callers changed to match.
3596 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
3598 Cleanup for gdb-3.94 release final:
3600 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
3601 the .c files from vx-share and nindy-share, from the various
3602 macros, since they are not found via ALLDEPFILES.
3603 (SFILES): Add tm-i960.h.
3604 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
3605 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
3607 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
3608 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.

3612 * am29k-tdep.c: Add contribution line.
3613 (examine_prologue): Cache information about function prologues in
3614 the misc-function-vector to avoid lots of references over the
3615 serial line while examining instructions.
3617 * core.c (core_close): New function made from cleanup_core.
3619 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
3620 remote-vx.c, remote.c, target.c, target.h,
3621 Update target_ops vector to add attach, close, and load entries.
3622 Use add_syms_addr_command, not add_file_addr_command, for
3623 add_file. Break out close routine from existing code.
3625 * dbxread.c (really_free_pendings): Don't free pending_blocks;
3626 they are in an obstack.
3627 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
3629 (define_symbol): Add symbol type parameter; change callers;
3630 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
3631 it to influence the symbol class on the i960.
3632 (define_symbol): Swap LOC_CONST's into target byte order.
3634 * exec.c (exec_close): New function.
3635 (exec_file_command): Call it.
3637 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
3638 Fix byte order of frame pointer.
3639 (read_var_value): Result of 0 if var's value can't be found,
3640 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
3641 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
3642 (locate_var_value): Use read_var_value and use its lazy address
3643 as the location of the var's value. Lint.
3645 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
3648 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
3649 obsolete Intel versions in favor of vxgdb versions.
3650 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
3651 code dealing with byte order of values, which Intel did in host byte
3652 order rather than gdb-4's target byte order.
3653 (i960_frame_chain_valid): Move to nindy-tdep.c.
3654 (examine_prologue, skip_prologue, frame_find_saved_regs,
3655 frame_args_address, leafproc_return, saved_pc_after_call,
3656 pop_frame): Add vxgdb versions from Mark Fox.
3657 (examine_prologue, frame_struct_result_address): Add code
3658 to deal with the saved value of G13 (struct return address
3660 (frame_args_address): Modify Mark's version to prefer the
3661 saved value over the current value in the topmost frame.
3662 Cache result in the frame info to avoid performance hair in
3664 (print_fault): Add gdb960 code for printing faults.
3665 (_initialize_i960): Actually call check_host.
3667 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
3668 add stub routines. FIXME, these currently just return zero!
3670 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
3671 (attach_command): Call target_attach, not target_open, now.
3673 * infrun.c (normal_stop): Make global, not static, for vx_attach.
3674 (child_attach): Rename from child_open.
3675 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
3676 don't confuse it with a zero step_resume_break_address.
3678 * inftarg.c (child_detach): Eliminate inferior_pid test.
3679 (child_files_info): Clean up message a bit.
3680 (child_ops): Use child_attach, not child_open, to attach.
3682 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
3683 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
3684 findvar.c to here, since it depends on the contents of the
3685 shadow_contents of breakpoints, but keep if #if 0 since it is
3688 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
3691 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
3692 (ptype_command, display_command): Eliminate have_inferior_p and
3693 have_core_file_p in favor of target_has_stack or
3694 target_has_execution.
3695 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
3696 code for actually finding the values of arguments, though we still
3697 keep track of the maximum stack offset for use in printing unnamed
3698 arguments. Handle missing FRAME_ARGS_ADDRESS.
3700 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
3701 (struct nindy_regs): Define registers passed to/from nindy.
3702 (nindy_fetch_registers, nindy_store-registers): Translate between
3703 nindy and GDB formats for the registers.
3704 (dcache_init): Statically allocate the cache, since it was being
3705 allocated by a malloc that was never freed anyway.
3706 (nindy_create_inferior): Error, not core dump, if no exec file.
3707 (nindy_before_main_loop): Use target_load, not target_add_file.
3709 * remote-vx.c (net_load): Specify large timeout for load
3710 requests. Allow user to break out with INTERRUPT.
3711 (net_break): Remove useless code, clean up. Change callers.
3712 (parse-args, skip_white_space, find_white_space): Clean up arg
3713 parsing to cope with quoted strings.
3714 (net_wait, net_quit): Never call error, just return status.
3715 (vx_read_register, vx_write_register): Cleanup status checking.
3716 #ifdef the code based on which CPU we are using (960 or 68k),
3717 FIXME, this should be completely general but it isn't yet.
3718 (vx_xfer_memory, vx_resume): Cleanup status checking.
3719 (vx_run_files_info): Improve message.
3720 (vx_load_command): Renamed from vx_add_file_command. Allow load
3722 (net_ptrace): Remove unused routine.
3723 (vx_wait): Adopt code from vxgdb960 to cope with broken
3724 connections to target machine and prompt to disconnect. Remove
3725 debug printouts. Map some EVENT_'s to SIGnals.
3726 (add_symbol_stub, vx_open): Print names of object files we found,
3727 and "ok" if we read their symbols OK. Clarify output in general.
3728 (vx_attach, vx_detach, vx_kill): Add these commands.
3729 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
3730 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
3731 "info files" output, and create_inferior, since we already have
3734 * stack.c (frame_info): Replace Frame_unknown with 0.
3735 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
3736 (return_command): Pop until the PC matches as well as the FP,
3737 so it works even if the FP is shared with another function,
3738 as in "frameless" or "leaf" procedures.
3740 * symfile.c (load_command): renamed from add_file_target_command.
3741 (add_syms_addr_command): renamed from add_file_addr_command.
3742 (add_syms_command): Stub to call target_add_syms.
3743 (_initialize_symfile): Change command names and descriptions,
3744 add-file => add-syms, and load from alias to its own command.
3746 * target.c (kill_or_be_killed, maybe_kill_then_attach,
3747 maybe_kill_then_create_inferior): Default for attempts to start
3748 a process, if one is already running, is to ask about killing
3749 it and retry if yes.
3750 (upstack_create_inferior): #if-0 it, strata obsolete it.
3751 (push_target, unpush_target, pop_target): to_close() a target
3752 before unstacking it.
3753 (target_info): Renamed from target_files_info.
3754 (_initialize_targets): Rename "i files" as "i target", accessible
3757 * target.h: Improve comments about the target_ vectored routines.
3759 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
3760 Convert commenting style to standard GNU style.

3762 (SKIP_PROLOGUE): No longer a no-op.
3763 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
3764 (*_REGNUM): Sort register numbers.
3765 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
3766 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
3767 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
3768 are now 10 byte extendeds, not 8 byte doubles.
3769 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
3770 for nindy versus vxworks targets. FIXME, this should possibly go
3771 in the target vector.
3772 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
3773 frame_saved_regs and arg pointer with each frame.
3774 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
3775 (FRAME_ARGS_ADDRESS): Use cached result.
3776 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
3777 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
3778 (PRINT_RAMDON_SIGNAL): Call print_fault.
3779 (POP_FRAME): Now works.
3781 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
3782 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
3783 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
3784 (ADDITIONAL_OPTION_HANDLER): use target_load, not
3787 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
3788 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
3790 * valarith.c (value_subscripted_rvalue): Avoid handling
3791 floats and doubles specially; it gave alignment errors. Lint.
3793 * valops.c (value_of_variable, value_of_this): Error if unknown
3796 * valprint.c (print_floating): Bcopy rather than pointer-deref,
3797 to avoid alignment problems.
3798 (value_print): Handle unknown value address.
3799 (cplus_val_print): Two args are ignored; remove them. Change caller.
3800 (val_print): Use unpack_long rather than pointer-deref.
3803 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
3804 to avoid alignment problems.
3805 (value_being_returned): Error if return value unknown.
3806 (set_return_value): Add bogosity warning, FIXME. *
3808 * TODO: A woman's work is never done.
3810 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
3811 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
3812 Add ieee-float.o to OBS.
3813 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
3814 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
3815 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
3817 Changes to generalize the VxWorks RPC protocol slightly, to handle
3818 i960 as well as 68000.
3820 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
3821 * vx-share/reg.h: Produce i960 regs #ifdef I80960
3822 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
3823 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
3824 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
3825 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
3826 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
3827 so they will move in target byte order rather than network
3828 byte order (happens to be the same).
3830 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
3832 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
3834 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
3837 Add contribution lines to various files, showing where they
3840 * breakpoint.c (break_insn, check_break_insn_size,
3841 read_memory_nobpt): Remove to mem-break.c.
3843 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
3846 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
3847 entry has bad register number. This change is not
3848 tested in this release, FIXME.
3850 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
3853 * value.h: Force value's contents field to be aligned to hold
3854 at least a double or a long long (if supported). This avoids
3855 doing bcopy's in and out of the contents field.
3857 (step_1): Avoid coredump under obscure circumstances when we
3860 * symtab.h (misc_info): Add field to misc function vector for
3861 any kind of cached information the target code desires. AMD
3862 29000 uses this to avoid repeating examine_function_prologue's.
3864 * coffread.c: Lint. Remove static symfile, read_section_header.
3865 core.c (have_core_file_p): Lint: remove.
3866 expprint.c (print_subexp): Lint.
3867 infptrace.c, valops.c, valprint.c: lint.
3869 Roll in changes from vxgdb-5.0.1:
3871 * symtab.h: Comment byte order of each address class. Add
3872 LOC_LOCAL_ARG for frame-relative args (960).
3873 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
3874 symtab.c, symmisc.c: ditto.
3876 * infrun.c (init_wait_for_inferior): Clear stop_signal.
3878 * remote.c (remote_resume): Error if resume with a signal.
3880 * symfile.c (prim_record_misc_function): Clear misc_info.
3881 (fill_in_vptr_fieldno): Check stub type of arg.
3883 * valops.c (value_cast): Avoid looking up names of types whose
3884 name we don't know, to prevent coredump. Sun CC produces typedef
3885 rtx and the name of *rtx is zero...
3887 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3889 Roll in changes from final AMD 29000 port (Tiemann).
3891 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
3892 for ../include/a.out.encap.h. This might not work now that BFD
3893 is separately compiled. Instead, BFD support for encap will have
3894 to translate machine type 29k into the right COFF_MAGIC.
3896 * infcmd.c: Remove references to inferior_pid that aren't used
3897 in actual ptrace calls; use target_has_execution, etc.
3898 (have_inferior_p): Remove function.
3899 (program_info): Print target info rather than "process number";
3900 avoid gratuitous messages unless from_tty.
3901 (run_stack_dummy, finish_command): Set proceed_to_finish.
3902 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
3903 main.c: Lint. Lose have_inferior_p().
3904 inferior.h (have_inferior_p): Remove, lint.
3905 (proceed_to_finish): Add flag to ask that all regs be saved
3906 by normal_stop, for the few commands that need it, speeding up
3907 serial I/O. Add comments to stop_registers.
3909 * remote-eb.c: Remove newline from breakpoint message we grep
3910 for. Never time out when running the user program.
3914 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3916 Roll in changes from vxgdb-5.0.1:
3918 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
3919 symbol in its raw form, we are processing an unlinked ".o" file.
3920 See if the target environment has assigned it an address, using
3921 target_lookup_symbol (VxWorks does), and enter it into the symtab
3924 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
3925 68k versions for a simpler version that assumes zero FP at bottom.
3926 Fixes bug of truncated stack reports.
3928 * target.h (target_lookup_symbol): Define this routine's args
3929 and result, finally.
3931 * target.c (nosymbol): Default routine for target_lookup_symbol.
3932 (target_default): Default lookup_symbol and call_function too.
3933 (files_info): Only print has_all_memory warning if a non-dummy
3936 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
3937 vx_convert_from_virtual): If target does not have floating point,
3938 zero register "values", and avoid doing cross-net conversions.
3939 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
3940 (vx_open): Rearrange code that attaches to target and reads
3941 symbols for all loaded modules, to work if some of the modules
3942 are not accessible. Add symbol_stub() and add_symbol_stub()
3943 as callbacks from catch_errors(). Allow connect attempt to be
3944 interrupted painlessly with ^C (FIXME, there are still some bugs
3945 if the interrupt happens during symbol reading.). Print
3946 final message with puts_filtered, since symbol messages are
3951 * main.c (catch_errors): Only print errstring if non-null.
3952 (command_loop): Avoid an ioctl per command to test ISATTY.
3954 * remote-vx.c (net_load): make static; avoid sophomoric msg.
3955 (vx_xfer_memory): Return correct result!
3956 (vx_files_info): Indicate whether target has float or not.
3957 (vx_lookup_symbol): Complain, not error, if target gone.
3958 (vx_open): Print "Connected" msg before disabling immediate-quit.
3959 [FIXME: lookup_symbol and vx_open changes need testing.]
3961 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
3962 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
3963 contributor lines and update copyrights to 1991.
3965 Changes from an attempted H-PUX host port:
3967 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
3968 defines PT_ATTACH and PT_DETACH but not PT_KILL.
3969 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
3970 * remote-vx.c: include <sys/time.h> for HPUX.
3971 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
3972 "core_file_command" routine to BFD regime. May not work yet.
3974 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
3976 * xgdb.c: Replace X10 version with some VJ version.
3977 (FIXME: Its copyright assignment is not on record.)
3978 * xgdb.c: Update include files to X11R4 (Xaw crud).
3979 (xgdb_display_source, create_text_widget): fix call to
3980 get_filename_and_charpos. Rewack source window stuff for X11R4
3981 (gleaned from include files, and "nm's" of binary libraries, since
3982 I had no doc available).
3983 (append_selection, append_selection_word): Disable with FIXME
3984 since R4 changed interface here.
3985 (create_buttons): Add back the old set of buttons.
3986 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
3988 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
3989 Roll VERSION to 3.94 (not yet final though).
3991 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3993 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
3994 obstack_int_grow, obstack_int_grow_fast): Eliminate
3995 cast on left of assignment, which gives MIPS cc fits and is
3998 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
3999 F_ALIAS. Use printf, not fprintf, when not passing a file
4001 (compare_opcodes): Check that identical instructions have
4002 identical opcodes, complain otherwise.
4004 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
4005 was reported by Roland McGrath.
4006 (unimp): Only match if exactly zero instruction. (Roland)
4007 (branches and traps): Generate all variations of these
4008 instructions with macros, based on a single call that defines
4009 each condition name and its binary representation.
4010 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
4012 * valprint.c (val_print_fields): Take, and use, format parameter.
4013 This means that "p/x struct" again prints the elements in the
4014 desired format. Changed callers.
4016 * stack.c (frame_info): Use filtered output, and indicate wrap
4017 points. Remove kludgy formatting designed to avoid line wrap.
4019 * utils.c (wrap_here): If the line is already full (because
4020 we had printed a long indent or long wrapped string), do an
4021 immediate newline-and-indent.
4023 * m68k-pinsn.c (print_insn_arg): Bugfix from
4024 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
4025 instruction is incorrectly disassembled as bkpt #8.
4027 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
4028 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
4029 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
4030 and then will dump core (sometimes). I traced it back to an
4031 uninitialized symfile_name in psymtab_to_symtab.
4032 (const_vol_complaint): Add quotes to message.
4033 (define_symbol): Only believe line number if gcc_compiled.
4034 Avoid allocating symbol if we will not return it.
4036 Add target strata support so that newly established targets go
4037 into their right place in the target stack (e.g. a new exec file
4038 doesn't wipe out the ability to access the running process).
4040 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
4041 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
4042 and initialize it properly in all the targets.
4044 * target.h: Document strata. Change return type of push_target.
4046 * target.c (nomemory): new function for dummy memory access.
4047 (tcomplain): Rename complain, now also used in symfile.c.
4048 (push_target): Push targets within strata. New return value shows
4049 whether new target is on top of stack or not. Always keep dummy
4051 (target_files_info): Ignore dummy target.
4053 * core.c (core_open): Warn user, and skip accessing file, if the
4054 core target is not the topmost target in the stack.
4055 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
4058 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
4059 target_ops, it doesn't belong there since we have no regs there.
4060 Change name of target from machine => memory to clarify.
4062 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
4064 * Freeze version 3.93 for release.
4066 * Makefile.dist: Handle vx-share and nindy-share subdirs
4067 properly when building gdb.tar.Z.
4069 * symtab.c: lint; add no_symtab_msg to consolidate the messages
4070 printed in various places, so I could change just one copy.
4072 * dbxread.c, coffread.c: Change references to bfd->iostream
4073 to cast to FILE *, now that BFD avoids needing types defined
4074 in other header files.
4076 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
4078 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
4079 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
4080 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
4081 (actually gcc -Wall).
4083 * dbxread.c: Remove first_global_sym, last_global_sym, since
4084 they are never referenced.
4086 * defs.h (baud_rate): Declare.
4087 main.c: Define it, and add the -b option to set it.
4089 * gdb-int.texinfo: Add text on how to define a new host or target
4090 architecture, prompted by Per Bothner's questions about MIPS
4093 * gdb.texinfo: Document "complaints". Change doc of -q since
4094 gdb no longer prints the copyright and blurb if you specify a file
4095 name to be debugged (just like Emacs). Add doc for Nindy-specific
4096 command line flags for specifying target serial port and such.
4097 Update copyright to 1991.
4099 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
4100 has taken over for us the job of ripping up executable files. The
4101 crud caused Per Bothner's port to not compile.
4103 * infrun.c (normal_stop): Avoid printing "Program exited
4104 normally" if we are in batch mode. This allows a GDB which
4105 executes a program on a target system, to behave like a Unix
4106 command (input from stdin, output to stdout, no extraneous
4109 * main.c (main): Allow additional machine-dependent command line
4110 options to be specified with the ADDITIONAL_OPTIONS,
4111 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
4112 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
4113 processing to occur just before the main loop with
4114 BEFORE_MAIN_LOOP_HOOK.
4115 (main): If a "core file" argument is specified, and it is not a
4116 core file, try it as a process ID to attach.
4117 (symbol_completion_function): Attempt to cope with
4118 "show screen-" TAB, not very successfully. This needs more work,
4120 (batch_file): New function, returns whether we are reading
4121 commands from an interactive tty on stdin, or from somewhere else.
4122 Called by normal_stop since it doesn't get from_tty passed down
4123 to it like many commands do.
4125 * remote-nindy.c: Handle command line options for nindy
4127 (nindy_before_main_loop): Prompt user for tty name if they
4128 don't specify it before getting to the interactive command loop.
4130 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
4131 and -r command line options. Also add hook before main loop
4132 to make it easy to specify a tty.
4134 * TODO: More things to do, one done.
4136 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
4138 * dbxread.c: Make complaint() calls pass pointer, not struct.
4139 Add complaints about badly formatted C++ type information
4140 (const/volatile indicator, and parse errors resulting in
4141 error_type). Fix C++ virtual member fn comment.
4142 (read_struct_type): Avoid bumping pointer if we got a parse
4143 error; this prevents our walking beyond the end of a string.
4144 Terminate loop on null char as well as semicolon.
4145 (process_one_symbol): Fix the LBRAC fix so that it uses the
4146 last previous SLINE, FUN, or SO record's PC address. C++ debug
4147 symbols did not have SLINE records in a useful order compared
4148 to the LBRAC records.
4149 (define_symbol): Handle "catch" records.
4151 * symtab.c (check_stub_type): Added new complain
4152 `stub_noname_complain' and added a consistency check to
4153 keep the debugger from crashing when finishing from an
4154 exception frame. A real fix will be needed later.
4156 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
4158 * infcmd.c (attach_command): Make global.
4160 * Makefile.dist (REMOTE_OBS): Make these compile by default,
4161 but make them easy to comment out. Perhaps later they should
4162 be enabled by what CPU you configure for? FIXME.
4163 (VERSION): Roll to 3.93.
4164 (pinsn.o): Remove rule for obsolete file.
4165 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
4167 Run down a problem that manifested by printing the wrong function
4168 name in stack traces of read_ofile_symtab. Turned out that the
4169 problem was the SunOS 4.1.1 (and previous) C compiler outputs
4170 the LBRAC symbol with an address in the *data* segment, which
4171 blew our binary search through the blocks.
4173 * dbxread.c: Use the complain() facility consistently to bitch
4174 about problems in the symbol file we are reading.
4175 (finish_block): Add code to check the nesting of the blocks;
4176 complain and Procrust them to fit if wrong.
4177 (make_blockvector): Check the order of the blocks, complain
4178 [but don't cope] if wrong.
4179 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
4180 symbols to be sure their PC value is greater than the last SLINE
4181 (line number) symbol we've seen, complaining and adopting the
4182 SLINE PC value if wrong.
4184 * symfile.h (struct complaint, complaint_root, complain,
4185 clear_complaints): Add.
4186 * symfile.c (complain, complaint_root, clear_complaints): Add
4187 facility to deal with non-fatal complaints and to regularize their
4189 (symbol_file_add): Clear complaint counters to allow new complaints.
4190 (initialize_symfile): Add 'set complaints' and 'show complaints'.
4192 * dbxread.c (dbx_symfile_read): Remember the address and size
4193 of the string table for the main symbol file, so we won't read it
4195 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
4196 to avoid reading the string table yet again. Lint.
4197 (throughout): Improve filtered output, including word wrap.
4198 (read_range_type): Improve Bothner's fix to handle other types too.
4200 * utils.c: Improve line wrap implementation. Handle unlimited
4201 width by making chars_per_line unsigned.
4202 (puts_filtered): New, easy, function.
4204 * defs.h (puts_filtered): add.
4206 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
4207 call the identical sort_symtab_syms() in symfile.c instead.
4209 * expread.y: Suggest the `file' command rather than `symbol-file'.
4211 * command.h (enum var_types): Add zinteger for seroable
4213 * command.c (do_setshow_command): Handle var_zinteger. Restructure
4214 nested if's into a switch.
4216 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
4217 we did not stop because of a breakpoint (it must have been for
4218 some other reason, like a "stepi"), so don't print anything.
4220 * symtab.c: Include <sys/types.h> all the time. Now that BFD
4221 doesn't include <sys/types.h>, old SunOS's require it for
4224 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
4226 A test port of gdb-3.92.6 to the Sony NEWS.
4229 Don't normally link in remote- or vx stuff.
4230 Some of it doesn't compile, and it wastes space for 99% of the users.
4231 Remove reference to no-longer-used HAVE_VPRINTF.
4232 Fixed BFD_DEP typo to BFD_DIR.
4234 Fix cast in arg to bfd_h_getlong.
4235 Make char *prefix be const.
4236 Fix how certain range types are mapped into builtin unsigned int types.
4238 Remove 2 #includes. They cause errors (on Sony, at least),
4239 and aren't needed (they wern't in earlier versions).
4241 print_address_symbolic should never demangle labels
4242 (since it prints *assembler-level* labels).
4244 [This was superseded by the change to printcmd below.]
4247 Add some "volatile" return types to avoid warnings.
4248 If MISSING_VPRINTF add vprintf function and not just macro
4249 (since vprintf is used in printcmd.c).
4251 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
4252 (The latter isn't grokked by some PCC-based compilers.)
4254 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
4256 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
4257 * nindy-share/coffstrip.c
4258 Added some forward declarations (otherwise, gcc complains
4259 about implicit extern redefined as static).
4261 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
4263 Changes inspired by Per Bothner:
4264 * printcmd.c (print_address_symbolic): Take additional parameter
4265 specifying whether to demangle.
4266 (print_address): Pass in asm_demangle to control demangling.
4267 (print_address_demangle): New fn, takes explicit arg to control
4269 * utils.c: Add new vars demangle and asm_demangle, and let them
4271 (fputs_demangled): If !demangle, just print the argument.
4272 (fprint_symbol): If !demangle, just print raw symbol.
4273 * valprint.c (val_print): Call print_address_demangle rather than
4274 print_address, to cause demangling to depend on the global
4275 rather than assembler-level demangling setting.
4276 * WHATS.NEW, gdb.texinfo: Document.
4278 * main.c (show_command): Show all settings if no arg.
4279 (initialize_main): Make "info set" the same as naked "show".
4280 * command.c (cmd_show_list): Handle prefix commands in the
4281 list, and print the name of the setting as well as its English
4282 description and value.
4284 Allow gdb functions to specify where a line should wrap if it
4285 exceeds the size of a terminal line. Use it to make the output
4287 * utils.c (set_screen_width_command): New fn, mallocs a buffer
4288 of the right size when screen width changes.
4289 (set_screensize_command, screensize_info): Remove #if 0'd fns.
4290 (wrap_here): New fn, indicates a point in the output where we
4291 should wrap the line rather than just letting it overflow at a
4293 (fputs_filtered): Implement wrapping.
4294 (n_spaces): New fn, returns a pointer to N spaces.
4295 (print_spaces_filtered): Use n_spaces.
4296 * defs.h (n_spaces): Declare.
4297 * stack.c (print_frame_info): Wrap with 4-space indent after
4298 fn name and before filename and line number.
4299 * printcmd.c (print_frame_args): Wrap with 4-space indent
4300 before each argument name is printed.
4301 * valprint.c (value_print): Wrap with no indentation before
4303 (val_print_fields): Wrap with indentation relative to nesting
4304 level before each field name.
4305 (val_print): Wrap with nesting indentation before array elements.
4306 * command.c (do_setshow_command): Avoid extra newlines,
4307 wrap with 4-space indent around values printed, end with period.
4308 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
4310 * breakpoint.c (breakpoint_1): Implement addressprint for
4311 "info breakpoints" display. Change file name and line number
4312 format to " at file:nnn" rather than " (file line nnn)".
4313 * gdb.texinfo: Document.
4316 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4318 Frozen for gdb-3.92.6 release.
4320 README, WHATS.NEW: Update for 3.92.6 release.
4322 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
4323 coffread.o from configs since it is now built by default.
4324 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
4325 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
4326 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
4327 from configs since it is now built by default.
4329 Makefile.dist: Update for release 3.92.6. Handle files that
4330 have been moved to ../include, ../getopt, or ../bfd. Add
4331 saber.suppress and tests directory. Add config.status to
4332 the release (it will say "none").
4334 coredep.c: Minor formatting fixes.
4336 These changes were made in early December but only checked in now:
4337 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
4338 nindy-share/nindy.c: lint
4339 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
4340 register values coming back from the target; we store values
4341 in target byte order everywhere.
4343 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
4345 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
4347 * valprint.c (cplus_val_print, val_print_fields): New functions,
4348 which print C++ objects. They conspire to avoid printing a
4349 virtual base class more than once, following all the twists and
4350 turns of C++ virtual base rules.
4351 (val_print): Call the above rather than do it by hand.
4353 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
4354 symbol file, not for added files like shared libs. This really
4355 needs to be generalized to a timestamp per file.
4357 * core.c (cleanup_core): Avoid coredump if no core file.
4359 * config.gdb: Accept -host or -target in place of +host or
4362 * coffread.c (find_linenos): Avoid desupported BFD interface
4363 to line numbers. We still read them manually rather than using
4364 BFD's "generic" features.
4366 * gdbrc.tex, threecol.tex: Add GDB reference card and its
4368 Makefile.dist: Add refcard to OTHERS list for creating tar files.
4370 * Makefile.dist: Eliminate use of $< in explicit targets.
4372 * readline/Makefile: Use $< rather than $*.c, which does not
4373 include the VPATH in GNU Make.
4375 * tconfig/i960-bout, tconfig/i960-coff: These are identical
4376 copies of tconfig/i960, added for global configuration
4377 compatability. All i960 versions can read both coff and b.out.
4379 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
4380 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
4383 * TODO: Think of more things to do.
4385 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
4387 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
4388 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
4389 64-bit float conversion.
4391 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
4392 equivalent to sun?os4 so global config works.
4394 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
4396 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
4398 * main.c: Only declare linesize once; declare pagesize not at
4399 all, since it is never used.
4400 (main): Clear newly allocated line before it is used.
4402 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
4404 Further stabilization for the Intel 960.
4406 * Makefile.dist: Parameterize the location of the "include"
4407 and "bfd" directories, as well as "getopt". Add symfile.c.
4408 Link in both dbxread and coffread. Fix up "make depend" to
4409 rewack the locations of include, bfd, and getopt in its output.
4411 * README: Document moving include files, improve some of
4414 * coffread.c: Move common code out to symfile.c. Change
4415 symbol_file_command style interface to use new *_symfile_init
4416 and *_symfile_read interface under BFD. Use BFD internal
4417 info to locate line table, symbols, etc.
4419 * core.c (core_fetch_registers): Rename to get_core_registers
4420 to avoid confusion with fetch_core_registers.
4421 (register_addr): Move to coredep.c, which is already machine
4422 dependent. This leaves core.c pretty clean of dependencies.
4424 * coredep.c (register_addr): Accept this routine from core.c.
4426 * dbxread.c: Move common code (with coffread.c, etc) into new
4427 symfile.c. Each psymtab now contains a pointer to the
4428 format-dependent function that knows how to read it in. Make
4430 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
4431 (process_one_symbol): Add code to complain about a "compiler bug
4432 we muzzle here", if we actually see it.
4434 * eval.c (evaluate_subexp): Insert missing "break" statements
4435 in code that determines whether a variable is an lvalue in
4436 memory, register, or whatever. I detected this via a compiler
4437 bug in which it *almost* mashed out the whole switch statement.
4439 * gdb-int.texinfo: Add minor sections on configuring gdb for
4440 release, and about the README file.
4442 * infcmd.c (registers_info): Fix formatting somewhat. Still
4443 not as pretty as before, but it handles byte swapping.
4445 * remote-nindy.c: If data cache routines are interrupted while
4446 waiting for the remote end, be sure that any uninitialized cache
4447 blocks are on the free list, not on the valid list!
4449 * symfile.h: Flesh out this header file with all the various
4450 routines and variables that have been merged in from dbxread.c
4451 coffread.c, and symtab.c to symfile.c.
4453 * symfile.c: New file, containing code common to dbxread.c,
4454 coffread.c, and some code from symtab.c. All generic code for
4455 reading symbol files should be in here now.
4456 (unrecord_misc_function): Remove unused function.
4458 * symtab.h: Remove file-reading things to symfile.h.
4460 * symtab.c: Remove file-reading things to symfile.c.
4462 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
4463 to decode i960 fault types.
4465 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
4466 target.c: Change type of the "resume" function from int to void,
4467 since its result was never used.
4469 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
4471 * main.c: Replace "stupid" with "caution"; you now "set caution
4474 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
4476 * infcmd.c (do_registers_info): Call val_print to deal with the
4477 byte order of the registers being printed. FIXME, this makes
4478 the formatting of the output uglier.
4480 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
4481 defined, call it for signals the debugger doesn't itself use.
4482 The i960 uses this for more detailed fault information.
4484 * remote.c (remote_open): If arg is null, print help rather than
4487 * sparc-xdep.c (register_valid): Avoid declaring size, since
4488 various modules will think of various sizes depending on the
4489 architecture of their tm-file. FIXME, we need protection against
4490 actually entering one of those modules, which would clobber
4491 storage if not for the target architecture compiled into gdb.
4493 * stack.c (up_command, down_command): Always print the frame
4495 (up_silently_command, down_silently_command): New commands
4498 * i960-pinsn.c (reg), i960-tdep.c: Lint.
4500 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
4501 more parameters than it used to.
4503 * findvar.c (registers): Increase slop to 256 bytes, which should
4504 protect us against even most RISC machines with large register
4506 (locate_var_value): Move declaration inside related ifdef.
4508 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
4509 throughout, to avoid throwing away buffered input from the board.
4510 (nindy_wait): Supply_register takes addr_of_value, not value.
4511 (i960_print_fault): Renamed from i80960_fault.
4512 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
4513 (nindy_store_registers): Avoid regs_changed stuff, just stuff
4515 (nindy_create_inferior): Don't bother to write PC_REGNUM since
4516 we can set the PC in the call to proceed(). Unpush nindy_ops
4517 before pushing it on top, to avoid message to user. Eliminate
4518 commentary from Unix machines that just misleads here.
4519 (reset_command): Fix error message to suggest target command.
4521 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
4523 Release 3.92.5 as frozen.
4525 Stabilize the merged release...with help from lint, Saber C,
4528 Everywhere: Add include files needed to declare return types
4529 of functions called.
4531 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
4533 * breakpoint.h: Add undeclared breakpoint functions, and some
4534 functions for display handling since I couldn't think of a better
4537 * breakpoint.c (insert_breakpoints): Make code for disabling
4538 shared library bkpts more likely to work. It's used when we
4539 rerun a program and stop before the shared library has been
4541 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
4542 cast from pointer, so it squeezes through catch_errors.
4543 (bpstat_stop_status): Fix logic broken some time ago. We now
4544 always create a bpstat if the stop address matches a breakpoint,
4545 even if we don't stop there -- just like the old code used to do
4546 before I got my fingers into it (sigh).
4547 (breakpoint_1): Print "ignore count" after "stop only if"
4548 condition, since that's how it actually works.
4549 (mention): Handle watchpoints as well as breakpoints.
4550 (watch_command): use set_raw_breakpoint and mention to do most
4551 of the work (and initialize all the fields!). Only pass one
4552 arg to parse_c_expression, since that's all it takes.
4554 * command.c (not_just_help_class_command): Rename arg to args
4555 since we ignore "unused argument" warnings on vars named "args".
4556 inflow.c (child_terminal_info): ditto.
4557 infptrace.c (kill_inferior): ditto
4558 main.c (catch_errors, version_info, quit_command, pwd_command,
4559 source_command, dump_me_command, editing_info,
4560 set_history_size_command, set_history, show_history,
4562 stack.c (locals_info): ditto
4563 target.c (target_files_info): ditto
4564 valprint.c (set_input_radix, set_output_radix): ditto
4566 * core.c: Remove old variables for handling core and exec file
4567 sections (data_start, data_end, stack_start, stack_end,
4568 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
4569 text_end, exec_data_start, exec_data_end, text_offset,
4570 exec_data_offset, data_offset, stack_offset). They're
4571 superseded the more general build_section_table and
4573 (get_exec_file): Mention the `file' command.
4574 (read_memory_check): Rename to memory_error, and only call it
4575 in the case of an actual error.
4576 (read_memory, write_memory): call memory_error.
4577 (core_fetch_registers): Register section name is ".reg".
4579 coredep.c: Remove a bunch of crud now that all this file does
4580 is pull the registers out of a core file.
4581 (fetch_core_registers): Rewrite to actually work, I hope.
4583 dbxread.c: Use a.out.gnu.h, not system a.out, now.
4584 Replace index() with strchr(). Remove all the pre-BFD macro
4585 definitions for accessing the symbol file.
4586 (struct dbx_symfile_info): Encapsulate the information that
4587 dbx_symfile_init needs to pass to dbx_symfile_read in this
4590 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
4591 dbx_symfile_discard): Rearrange symbol file reading to divide
4592 the format-specific part from the format-independent part,
4593 leaving the format-independent part such as file name expansion
4594 and opening in symtab.c. This replaces
4595 partial_symbol_file_open and partial_symbol_file_read.
4596 Symbol_file_read, add_file, add_file_target_command,
4597 add_file_addr_command move to symtab.c. Pass an explicit
4598 "mainline" flag for when reading the main symbol table, rather
4599 than relying on the offset address to be zero or nonzero.
4601 (dbx_symfile_read): Don't allow void *'s to be printed as
4603 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
4604 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
4605 macro" debug version really work.
4606 (read_dbx_symtab): Remove unref'd parameter inclink.
4607 Avoid swapping N_SLINE symbols, for speed.
4608 Merge N_TEXT!N_EXT case with the other external symbol
4609 definitions' case. Add comments.
4610 (start_psymtab): Allocate the symfile name in the psymtab on
4611 the psymbol_obstack, rather than using the caller's storage.
4612 (end_psymtab): Only allocate a dependencies list if there are
4614 (psymtab_to_symtab_2): Use BFD when reopening file to read
4615 its symbols for real.
4616 (read_struct_type): Add FIXME comments where it needs work
4618 (read_huge_number): Add FIXME about overflows.
4619 (read_range_type): Add FIXME about comparing a long to 1<<32.
4621 * coffread.c: Minor changes to move things closer to the new
4622 regime with symtab.c and dbxread.c Major work is still needed
4625 * exec.c (exec_file_command): Remove old variables (see core.c
4627 (xfer_memory): If memory transfer is right at the end of a
4628 section, don't lose.
4630 * findvar.c (get_saved_register): If value is in a real
4631 register, LVAL is lval_register, not lval_memory.
4633 frame.h: Declare print_sel_frame and record_selected_frame.
4635 gdb-int.texinfo: New file, for GDB internals documentation.
4636 Very simple, unformatted doc of cleanups is there for now.
4638 gdbcore.h: Remove obsolete variables that described a.out
4639 section addresses and offsets. (See core.c above.)
4640 Declare fetch_core_registers and registers_fetched.
4642 getopt.c: Declare char *alloca(); even on SPARC.
4644 infcmd.c (run_command): Call target_kill rather than
4646 (step_command, next_command, stepi_command, nexti_command):
4647 Declare from_tty parameter even though we don't use it.
4648 (run_stack_dummy): argument BUFFER is a char array, not
4649 a pointer to REGISTER_TYPE.
4650 (finish_command): using_struct_return needed a value *,
4651 not a struct symbol *.
4653 * infptrace.c (child_xfer_memory): To avoid dependency on
4654 where sections are in memory, try PT_WRITE_D and if that fails,
4655 try PT_WRITE_I. Most Unixes don't care which you use.
4657 * infrun.c (step_resume_break_shadow): Change to array to
4658 match other breakpoint shadow storage.
4659 (clear_proceed_status): Pass address of bpstat to
4660 bpstat_clear, not the bpstat itself.
4661 (child_create_inferior): FIXME comment about if the child
4663 (start_inferior): Remove old function.
4664 (child_open): Use target_kill rather than kill_inferior.
4665 (wait_for_inferior): Ditto.
4666 (insert_step_breakpoint, remote_step_breakpoint): Use
4667 new step_resume_break_shadow.
4669 * inftarg.c (child_wait): If all child processes die,
4670 pretend that the one being waited for exited with signal 42.
4672 * main.c (command_line_input): When scanning for comments,
4673 don't coredump on unclosed quotes.
4674 (quit_command): Use target_kill rther than kill_inferior.
4675 (_initialize_main): Rename class_user from "user" to
4678 * printcmd.c (print_command_1): Initialize "fmt" if no format
4679 is specified by the user.
4680 (print_frame_args): Only add to args_printed if we are
4681 actually fetching args from the stack (avoiding undefined
4683 (_initialize_printcmd): Remove bogus \{ from string.
4685 * remote-eb.c (eb_open): Avoid coredump on no argument.
4687 * remote-nindy.c: Bring out of Intel environment into new
4688 target environment. Remove all conditional compilation on
4689 I80960. Massive hacking throughout.
4690 (nindy_xfer_inferior_memory): New routine stolen from
4692 (nindy_create_inferior): New routine pieced together, probably
4693 not quite working yet.
4694 (nindy_ops): New target_ops struct for nindy.
4696 * remote-vx.c: Use write_memory rather than target_write_memory
4697 to get error checking.
4698 (vx_add_file_command, vx_open): Use symbol_file_add rather than
4700 (vx_create_inferior): Use target_terminal_ours...
4702 * signame.c (_initialize_signame): Always initialize, since
4703 we need the table for things other than psignal.
4705 * solib.c (solib_add): Use symbol_file_add, not add_file.
4706 (solib_address): Return boolean result rather than struct
4707 pointer which nobody else knows the type of.
4709 * sparc-tdep.c, valops.c: Use write_memory rather than
4710 target_write_memory, to get error checking.
4712 * stack.c (locals_info, catch_info, args_info,
4713 get_selected_block, frame_command, up_command): Use
4714 target_has_stack, rather than have_inferior_p or
4717 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
4719 * symfile.h: New file, defining the interface between the
4720 generic and object-file-specific symbol reading code.
4722 * symtab.c: Move generic symbol-reading interface to symtab.c,
4723 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
4724 table to map BFD targets to symbol-reading modules in GDB.
4725 Change index to strchr.
4726 (lookup_struct_elt_type): Use error() rather than hand-made
4727 simulations thereof.
4728 (lookup_partial_symbol): Speedup slightly when length == 0.
4729 (symbol_file_add): New function.
4730 (symbol_file_command): Call it.
4731 (symfile_open, symfile_init): New function.
4732 (add_file_target_command, add_file_addr_command): moved from
4735 * target.c (target_command): use target_kill.
4737 * target.h (target_files_info): Don't declare, never called
4740 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
4741 files to determine stack end address.
4743 * valarith.c (value_x_binop, value_x_unop): Change error message
4744 to be more useful. Pass proper argument to value_struct_elt.
4746 * valops.c (value_assign): FIXME comment that long long
4747 bitfields will break here.
4749 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
4750 Update `make saber_gdb' to work better.
4752 * TODO: A woman's work is never done.
4754 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
4755 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
4756 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
4757 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
4758 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
4759 valops.c, valprint.c, exec.c: Lint.
4762 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
4764 Continuing Intel 960 port merge of GDB.
4766 * Makefile.dist: Merge i960 "nindy-share" files. Rename
4767 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
4768 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
4769 Wack over "make depend" so it handles files in subdirectories
4770 vx-share, nindy-share, bfd, and in the current directory.
4772 * blockframe.c (get_prev_frame_info): Remove fatal error
4773 if stack not defined.
4775 * core.c (core_open, core_detach): New functions that handle
4776 the old "core-file" command as "target core" and "detach" instead.
4777 (core_file_command): Call them.
4778 (core_xfer_memory): Use common routine xfer_memory.
4780 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
4781 dbxread now uses bfd for everything but symbol reading itself.
4782 BFD internals are used to drag out the relevant file offsets.
4783 (partial_symbol_file_open): Change args all around for BFD.
4785 * symtab.c: Rename "value" to "val" everywhere, so we can
4787 (symbol_file_command): New command, moved from dbxread.c
4788 and coffread.c. It uses BFD to read the file, then vectors
4789 based on its type, to dbx or coff symbol readers.
4790 * symtab.h: Extern a few vars for symbol_file_command.
4792 * target.h: Breakpoint takes a char * save area, not a char **.
4794 * valprint.c (val_print): When unpacking bitfields, offset
4795 the address in gdb of the value, if it is declared with a shorter
4796 type. Remove the last "runtime kludge test" of host byte order.
4798 * utils.c: Remove old my_bfd_read routine.
4800 * stack.c (frame_info): Use target_has_stack. Print program counter
4801 register's actual name rather than "pc", since it's called the
4802 "ip" (instruction pointer) on the i960 (sigh).
4804 * target.c (target_command): Add command for selecting a target
4805 type and calling its open routine. This is used for initiating
4806 communication with a particular target, in a generic way.
4808 * tm-i960.h: Update for modern gdb. Remove semicolons from
4809 various macros. Handle reading struct return convention, and
4810 error-out attempts to return structs with the "return" command.
4811 Be sure gdb doesn't think we know how to call functions in the
4814 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
4815 to i960_xxx in lower case.
4816 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
4817 not being defined yet.
4819 * remote.c (remote_open): Call start_remote to initialize
4820 wait_for_inferior during open.
4821 (remote_xfer_inferior_memory): Return length written rather
4824 * remote-vx.c (target_command -> vx_open): Use new generic
4826 * remote-eb.c, inftarg.c, exec.c: ditto.
4828 * infrun.c: Fix comments.
4829 (attach_program -> child_open): Use new generic target command.
4830 (wait_for_inferior): Clear saved register values before target_wait,
4831 so target_wait can set some of them if convenient.
4833 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
4834 Return success indicator, not void.
4835 (child_xfer_memory): Avoid fetching initial word if we'll

4861 Merge Intel 960 port of gdb, continuing...
4863 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
4864 symbol_file_command): Pass from_tty arg to hush 'em up.
4866 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
4867 Add magic numbers for 960 COFF format.
4869 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)

4892 Fri Apr 20 13:47:15 PDT 1990
4895 Thu Apr 19 09:54:28 PDT 1990
4896 Add 'reset' command.
4898 Wed Apr 18 09:48:07 PDT 1990
4899 After opening remote tty, wait for 1 second to go by without input
4900 from it before trying to talk to NINDY (fixes problems with the
4901 Heurikon HK80/V960E).
4903 Mon Apr 4 16:33:05 PDT 1990
4904 Some output was not being suppressed in 'batch' mode.
4906 Thu Mar 22 15:31:11 PST 1990
4907 Ask user if old symbol table should be deleted when new file is
4910 Allow user to run a program downloaded before gdb960 was brought up.
4912 Correct "exec-file" help message for i80960 context.

4944 - eliminated opcode.h: incorporates tables into i960-pinsn.c
4945 - moved 960-specific routines from i960-pinsn.c to i960-md.c
4946 - made disassembly interface identical to that in gdmp960.
4950 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
4952 * target.h: Allow targets to stack. Add target_has_memory,
4953 _registers, etc. Restructure memory access and "info files"
4954 to walk the target stack.
4955 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
4956 target.c: Change tables to match target.h.
4957 * inflow.c (child_mourn_inferior): pop child_ops.
4958 (generic_mourn_inferior): Use new has_stack flag.
4959 * infptrace.c (child_xfer_memory): New memory regime.
4960 * inftarg.c (child_files_info): New "info files" regime.
4961 * remote-eb.c: New memory regime, new info files.
4962 * remote-vx.c: New memory regime, new info files. Now use
4963 separate targets for VxWorks attachment to machine, and
4964 actually running a process under VxWorks, since one has
4965 stack & execution & regs and the other doesn't.
4966 * remote.c: New memory regime, new info files.
4967 * sparc-xdep.c (fetch_core-registers): New memory regime.
4968 * target.c: New routines and support for stacked targets,
4969 new memory regime, new info files regime.
4972 Generalize section handling for an arbitrary number of sections,
4973 including use of the new BFD (binary file) library.
4974 * gdbcore.h: Add struct section_table.
4975 * exec.c (build_section_table): Iterate all sections and
4976 record what gdb needs to know about them.
4977 (exec_command): Use it.
4978 (exec_xfer_memory): Use the table.
4979 (exec_files_info): Print the table.
4980 * core.c (core_file_command, core_xfer_memory, core_files_info):

4983 * dbxread.c: Quick changes to make it compile with new BFD.
4984 * utils.c (error): Avoid using bfd_error in generic routines.

4988 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
4990 * inferior.h (attach_flag): Export.
4991 * infcmd.c (run_command): use new target_create_inferior.
4992 * infrun.c (child_create_inferior): Don't return result.
4993 * Makefile.dist (VERSION): 3.91.4.

4997 * breakpoint.c (bpstat_num): Handle breakpoints which have
4998 since been deleted, such as temporary breakpoints.
4999 infcmd.c (program_info): ditto.
5001 * core.c (core_file_command): Display the frame where the core
5006 * remote-vx.c (target_command): Merge in target command from
5007 targ-vx.c. A few other cleanups.
5009 * TODO, Projects: Lots more stuff to do...
5011 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
5013 Massive changes to wall off the remote-debugging interface
5014 behind a function vector. The port to handle VxWorks targets
5015 is also part of this.
5017 All files: Replace references to renamed functions,
5018 remove references to remote_debugging, remove references to
5019 have_include_file, have_core_file in favor of target_has_stack,
5020 target_has_memory, etc.
5022 * Modularize the breakpoint interface.
5023 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
5024 a breakpoint instruction.
5025 breakpoint.c: struct breakpoint's shadow_contents now sized as
5027 (insert_breakpoints): Vector to target to install breakpoints.
5028 (remove_breakpoints): Vector to target here too.
5029 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
5030 sparc-tdep.c (single_step): Use new breakpoint interface for
5031 the single-step breakpoints.
5032 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
5033 New file, contains routines to insert and remove breakpoints by
5034 reading out the old contents and later replacing them. This is
5035 how ptrace breakpoints work, and many remote systems as well.
5037 * tm-vxworks68.h: New config file, overrides a few things for
5038 Wind River's preferences.
5040 * target.h: New file, for transfer vector used to talk to the
5041 inferior (child, attached, core, exec, remote, etc). All accesses
5042 to the thing being debugged should come through these vectors.
5043 target.c: New file, routines to handle transfer vector.
5044 (various files): Add transfer vectors XXX_ops for the various
5045 targets and pseudo-targets (core files, etc) we support.
5047 * breakpoint.c (bpstat_stop_status): Further explorations of
5048 watchpoints and why things don't work all the time.
5049 (bpstat_alloc): New fn to allocate a bpstat and chain it.
5051 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
5052 the local gdbinit if it doesn't already have it.
5054 * core.c (core_ops): add and install.
5055 Allow core debugging without exec file.
5057 * dbxread.c (free_and_init_header_files): Merge two fns.
5058 (end_symtab): Free named symbol table when a new version comes in.
5059 (read_dbx_symtab): Relocate all kinds of symbols with base
5060 address. First step toward handling different text, data, bss
5062 (add_file_addr_command): Renamed add_file_command.
5063 (add_file_command): Vector to remote handler.
5064 Add "load" as an alias for "add-file" command.
5066 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
5067 non-returning functions.
5069 * exec.c: Add exec_ops, and push it as a target when an exec
5072 * infcmd.c (run_command): Pass executable file name and arg list
5073 separately when starting an inferior. Permit "run" when no exec
5074 file is specified, for VxWorks.
5075 (detach_command): Move to child_detach in inftarg.c.
5077 * inftarg.c: New file. Unix-child-specific routines, and the
5078 child_ops structure.
5080 * inferior.h (registers): Export "registers" as the way for
5081 target dependent register handlers to find gdb's local copy of
5082 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
5083 since it is now used by places that want wait_for_inferior to
5084 handle the grunge but want to see every trap from the inferior.
5086 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
5087 Eliminate remote_debugging hooks in terminal handling.
5089 * infrun.c: Replace start_inferior with child_create_inferior.
5090 Move all the hair of Unix shells and ptrace idiosyncracies into
5091 child_create_inferior, so remote handlers don't have to deal.
5092 Remove running_in_shell. Rename stop_after_attach to
5093 stop_soon_quietly, and use it in a few other places where we want
5094 to just call wait_for_inferior and get control back on the first
5095 trap. trap_expected now never takes a value > 1.
5096 (init_wait_for_inferior): Initialize static vars when a new
5099 main.c (gdbinit): Add new hook for .gdbinit file name, let
5100 it be overridden by config files as GDBINIT_FILENAME.
5101 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
5102 Both of these are used for VxWorks gdb.
5104 mcheck.c: rename include file "gmalloc.c" to avoid problems
5105 with system include file "malloc.c".
5107 param-no-tm.h: New include file, same as param.h but does not
5108 include the default "tm.h" file. This is used in files where
5109 the target is known, e.g. remote-eb.c or sparc-xdep.c.
5111 param.h: Now just a shell that includes tm.h and param-no-tm.h.
5113 remote-vx.c: New file, VxWorks remote debugging support. Uses
5114 RPC routines that are shared with the target system, in directory
5117 remote.c: Vectorize remote interface.
5119 source.c: Globalize source_path, and make an alias "l" for "list"
5120 since we now have the "load" command.
5122 sparc-xdep.c: Use new param-no-tm.h.
5124 symmisc.c (free_named_symtab): Add new function from Wind River.
5125 However, ifdef it out for now while we think about what it should
5128 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
5130 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
5131 non-Unix-children handle this with their own code in the target
5134 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
5135 source and target lists. Add vx-share to default list of include
5136 directories. Add new files to src and target lists: mem-break,
5137 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
5138 ${srcdir} versions of munch and createtags are used.
5140 * valops.c (find_function_addr): Split out of call_function.
5141 (call_function_by_hand): Rename call_function; this function
5142 calls functions in the target by laboriously patching the target
5143 word-by-word with the right stack, args, regs, etc.
5146 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
5148 Handle AMD 29000 a bit better.
5150 * remote-eb.c (readchar): Mask received char log to make it readable.
5151 (remote_start): Pass arguments down to executing program.
5152 Make startaddr unsigned.
5153 infrun.c (start_inferior): Accept args, pass them to
5155 infcmd.c (run_command): Pass args down to start_inferior.
5157 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
5158 the target object file format.
5159 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
5161 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
5162 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
5164 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
5166 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
5167 * TODO: We did a few things, we have more to do though.
5169 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define.
5170 * inflow.c (inferior_died): Clear deferred stores.
5172 * Debug problems with dummy frames and calls to the inferior.
5173 * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME): Move to sparc-tdep.c.
5174 * sparc-tdep.c (do_restore_insn): Simplify.
5175 (sparc_frame_find_saved_regs): Simplify and fix what we find.
5176 (sparc_push_dummy_frame): Simplify and fix what we push.
5177 (sparc_pop_frame): Slightly more hair here, deciding whether
5178 we are restoring a saved PC or returning to a return address in %i7.
5179 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
5181 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
5182 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
5183 * obstack.h (chunkfun): ditto.
5184 * defs.h (xmalloc, xrealloc): ditto
5186 * utils.c (quit): Grab the terminal from the child if necessary.
5188 * inflow.c (term_status_command): Rename to term_info, change
5191 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
5192 (is_delayed_branch): Speed up.
5193 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
5194 Still missing some float ops, and needs testing.
5196 * Support for input and output radixes other than base 10
5197 * defs.h (input_radix, output_radix): Declare.
5198 * expread.y (yyparse, parse_number): Handle changes of input
5199 radix, and ambiguous names-or-numbers in radixes >10.
5200 * printcmd.c (print_scalar_formatted): Print formatted hex
5201 numbers in varying column widths.
5202 * valprint.c (val_print): Use output_format to print scalar ints.
5203 (set_input_radix, set_output_radix, set_radix): Create.
5204 (set_output_radix): Set output_format from output_radix.
5205 (_initialize_valprint): add `set radix' but leave the others off.
5207 * main.c (execute_command): Let stupid questions be turned off.
5208 (_initialize_main): Handle "set stupidity", etc.
5210 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
5211 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
5213 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
5215 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
5216 bfd stuff is still screwed up, but with some manual work, it
5219 * breakpoint.c (bpstat_do_actions): Start over if a command
5220 proceeds the inferior, since the inferior will have stopped and
5221 will need to have its new stop-actions taken care of.
5223 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
5224 compiler fits, simplify it.
5226 * gdb.texinfo (directory command): Doc new dir command.
5227 source.c (directory_command): "dir" now puts things on the front
5228 of the path, moves dups up front, and handles multiple names
5229 on the command line, inserting each one in order. It also
5230 blows away cached line and full_filename info.
5232 * stack.c (backtrace_command): Skip "more stack frames follow"
5235 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
5236 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
5237 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
5238 The only odd one was Gould NP1, which had defined vprintf to
5241 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
5242 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
5243 variable, inspect_it.
5244 valprint.c (print_string, val_print): Use the global inspect_it
5245 to indicate whether to print in Epoch style or normal style.
5247 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
5249 * printcmd.c (call_command): add an alias for the "print" command
5250 which runs expressions and doesn't print the result if void.
5251 (print_command_1): implement it.
5253 * command.c: Remove #if 0'd code. Initialize all the fields
5254 in add_cmd (). Rename do_nothing_command to
5255 not_just_help_class_command, and make it externally visible.
5256 command.h: add user_commands to struct.
5257 * main.c (define_command): Don't overload c->function with a char
5258 string as well as a function pointer.
5260 * eval.c (evaluate_subexp): Reinstall tiemann changes to
5261 calling convention of value_struct_elt () that got dropped in
5264 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
5265 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
5267 * tm-sparc.h (POP_FRAME): replace some constants with defines.
5269 * sparc-xdep.c (store_inferior_registers): defer stores to regs
5270 until a good time (e.g. when we are about to run the child),
5271 saving ptrace calls.
5272 * infrun.c (proceed): handle DO_DEFERRED_STORES.
5273 * tm-sparc.h: define DO_DEFERRED_STORES.
5275 * sparc-xdep.c (store_inferior_registers): when storing float
5276 registers, don't store stack regs too. When storing the SP,
5277 however, DO store the stack regs too. This fixes a bug in which
5278 the dummy frame is not recognized when a call_function finishes,
5279 because its frame pointer (in the stack regs) was never
5281 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
5282 even though we don't know how to read them from an inferior.
5283 valops.c (call_function): Comment about storing SP.
5285 * infrun.c (save_inferior_status): Save away the original bpstat
5286 chain so it can be restored later. Install the copied version for
5287 use by whoever saved the status. It will be blow away by
5288 restore_inferior_status, and the original chain restored. This is
5289 important for people who have pointers into the original.
5291 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
5292 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
5293 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
5296 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
5298 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
5299 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
5300 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
5302 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
5304 * Merge Mike Tiemann's multiple inheritance changes from Sun.
5305 Store the baseclasses in a type struct starting from array element
5306 0 rather than from the unusual array element 1.
5308 dbxread.c: the above.
5309 (virtual_context): Add
5310 Read new debug information about which virtual function table
5311 a virtual function is from, and store it in fn_field.fcontext.
5313 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
5314 TYPE_FN_FIELD_STATIC_P.
5316 symtab.c: the above.
5317 valops.c: the above. Handle pointer casts of object *'s.
5318 (search_struct_method): Add.
5319 (value_struct_elt): First arg is now a pointer to a value, and is
5322 valprint.c: the above.
5323 values.c (value_virtual_fn_field): Add type arg. Handle
5324 offsetting to the proper object when calling virtual fns.
5326 (baseclass_addr): Add valuep arg.
5328 * README: Document the current state of BFD config (missing).
5329 * TODO, ChangeLog, Makefile.dist: Roll version.
5330 * WHATS.NEW: Add summary of changes since 3.5.
5332 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
5334 * dbxread.c (read_struct_type): Clear bit vectors whenever
5336 symtab.c (B_CLRALL): define.
5338 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
5339 using == rather than =. Huh... This fixes the dreaded problem
5340 wherein builtin_type_int becomes TYPE_CODE_FLT.
5342 * core.c (info_files): Show the inferior pid.
5344 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
5345 already knows how to look in the source directory.
5347 * Remove psymtab hair from many places. Remove duplicated code
5348 for searching symbol tables. Hide psymtabs from most places.
5349 Make it fast to get from a psymtab to its symtab.
5351 blockframe.c (blockvector_for_pc): Remove psymtab hair.
5352 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
5353 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
5354 dbxread.c: export psymtab_to_symtab, make it work if called N times.
5355 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
5356 new symtab completely. New psymtabs get symtab pointer
5357 initialized to zero. Remove MI warning printf.
5358 symtab.h: Comments. Add psymtab to symtab pointer.
5359 (PSYMTAB_TO_SYMTAB): New macro.
5360 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
5361 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
5363 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
5365 (print_frame_info): Avoid special-casing symbols that have not yet
5368 * source.c (open_source_file): Quick path if we have already
5369 located the source file by its full name.
5371 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
5372 find_pc_psymtab. When a name is found in the misc function
5373 vector, search the symbol table for its mangled name, not the
5374 name that the user typed.
5376 * bfd.h: Fix missing comment terminators, make #endifs match.
5378 * valarith.c (value_less): Handle unsigned int comparisons.
5379 Add FIXME about pointer compares, which assume host and target
5380 pointers are the same.
5382 * command.c (do_nothing_command): lint
5383 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
5384 fix comments on debug symbol format for visibility. Actually set
5385 visibility of symbols.
5386 main.c (echo_command): lint; use <readline/history.h>.
5387 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
5388 obstack.h (_obstack_blank): Rearrange pointer math to avoid
5389 pointing past end of allocated memory; saber complains.
5390 obstack.h: Declare the external functions that we use.
5391 valarith.h: use <string.h>
5392 solib.c (solib_add): lint.
5394 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
5396 * main.c (initialize_main): Default info_verbose to off, now that
5397 symbol reading is fast.
5398 (quit_command): Avoid clobbering exec_bfd while quitting.
5400 * Initial BFD (binary file diddling library) merger:
5401 coffread.c: Change AOUTHDR to struct exe_hdr.
5403 core.c: initialize initialized data at compile time.
5404 (core_file_command): Move from coredep.c, convert to bfd.
5405 (xfer_core_file): Convert to bfd.
5406 exec.c (exec_file_command): use bfd routines.
5408 mips-tdep.c: Remove exec_file_command and friends.
5411 * coredep.c: (fetch_core_registers) Convert core_file_command to
5412 fetch_core_registers.
5413 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
5415 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
5416 (my_bfd_read): More bogosity, which I don't think we call.
5417 (program_name): Remove this atrocity asap!
5419 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
5422 values.c: allocate_repeat_value was not clearing the
5423 optimized_out field.
5424 (value_static_field): minor stylistic fix (wrong macro was used).
5425 valops.c (value_struct_elt_for_address): didn't work for C++
5428 * signame.c (_initialize_signame): Initialize signal names once.
5430 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
5431 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
5432 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
5434 * remote-eb.c: Support user-settable baud rates on the serial port.
5436 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
5438 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
5440 * tconfig/sun3os4: Remove warning about native assembler,
5441 since it also occurs in the xconfig file.
5443 * findvar.c (registers): Allocate some slop after `registers'
5444 to prevent stray accesses from trashing the next variable.
5446 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
5447 on the sun-3, by changing the #ifdef from `sun3' (which is not
5448 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
5449 vars, which happened to follow `registers' in the executable.
5451 * readline/history.c (history_search): Heed gcc-2's advice
5452 and parenthesize && inside ||).
5454 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
5455 tm-29k.c: Insert FSF copyright headers.
5457 * remote-eb.c: Better comments.
5459 * Makefile.dist: Update to 3.91.6.
5460 * TODO: note PREPARE_TO_STORE problem.
5462 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
5464 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
5466 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
5468 * infrun.c (wait_for_inferior, at end): Don't set up
5469 prev_* if the inferior no longer exists.
5471 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
5472 CANNOT_EXECUTE_STACK.
5473 valops.c (call_function): Use it.
5475 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
5477 * inferior.h (PC_IN_CALL_DUMMY): New macro.
5478 infrun.c (wait_for_inferior, 2 places): Use it.
5480 * values.c (value_being_returned): Only use
5481 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
5483 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
5484 right thing for remote-eb.c.
5486 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
5487 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
5489 * blockframe.c: Put get_frame_saved_regs inside #if !defined
5490 (FRAME_FIND_SAVED_REGS).
5492 * findvar.c ({fetch,store}_registers): Check for
5493 REMOTE_{FETCH_STORE}_REGISTER macro.
5495 * findvar.c (get_saved_register): Add argument lval and
5496 change meaning of argument addr.
5497 findvar.c: Change calls to get_saved_register to reflect
5498 new calling convention.
5499 valops.c (value_assign): Use get_saved_register instead of
5500 find_saved_register.
5502 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5504 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
5505 an (uninitialized) pointer to one. Use "&" when passing it
5508 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5510 * coffread.c (getfilename): Use DGUX x_offset and x_name if
5513 * coffread.c (symbol_file_command): Put semicolon after
5515 Put safe_to_init_tdesc_context in #if defined (TDESC).
5516 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
5517 coffread.c: #include <sys/stat.h>.
5518 (read_coff_symtab): Typo: in_source_files -> in_source_file.
5519 Add missing ')' in check for "lc%" and friends. Remove
5521 Declare read_one_sym() at top of file.
5522 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
5523 MC68WRMAGIC can have the same value without causing a duplicate
5526 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
5528 * Allow a Makefile to be built without building the
5529 tm and xm file links that screw up builds in subdirectories.
5530 This is done with `config.gdb none', then you can do things
5531 like `make gdb.tar.Z'.
5532 * tconfig/none: Config file for no target system
5533 * xconfig/none: Config file for no host system
5534 * config.gdb: If no TM or XM files are called out by the
5535 host or target file, don't make links for them.
5537 * cplus-dem.c: Add documentation.
5539 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
5540 simple error, so the user's gdb doesn't crash due to some object
5541 file problem (e.g. somebody is rebuilding the file out from under
5544 * printcmd.c (print_address_symbolic): demangle the symbol.
5546 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
5547 Motorola copyrights in it. Make "make gdb.tar.Z" work.
5548 (alldeps.mak): sort and uniq all results from this; duplicates
5549 hose gdb.tar.Z link building. Remove RCS files from
5550 tconfig and xconfig. Add config files for sun386. Add
5551 a few odd files to OTHERS and HFILES.
5553 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
5555 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
5556 Roll version number to 3.91.5. Make lint work in bindir.
5558 * README: Document cross-debugging and new file structure.
5560 * blockframe.c: Lint. Include "value.h" to declare read_register.
5561 (find_pc_partial_function): remove duplicate line.
5563 * command.h: Lint. Declare error_no_arg and dont_repeat.
5565 * tm-news.h: Remove inadvertently duplicated stuff.
5567 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
5568 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
5570 * config.gdb: Allow `config.gdb host target' form. Clean
5571 up previous change that printed bogus messages when you just said
5574 * core.c: #include "command.h" for lint.
5577 * main.c: Remove some casts of enums. Lint.
5584 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
5586 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
5587 read it from memory. This will allow us to save ptrace calls
5588 eventually. Changed caller single_step too.
5590 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
5591 that we aren't going to use, saving many ptrace calls, especially
5592 when watchpointing or single stepping. Use some #define's for
5594 (store_inferior_registers): Ditto.
5595 (core_file_command): Use some #define's for constants.
5597 * tm-sparc.h: Add #define's for some register numbers, so we
5598 can eliminate the use of random constants in sparc-xdep.c.
5600 * stack.c (frame_command, print_frame_info, up_command,
5601 down_command) Remove frame_changed, since it
5602 causes a bug and doesn't seem to do anything useful. In some
5603 places it was used as a flag, in others as a stack level (?).
5605 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
5606 default is to use the portable (vprintf) version rather than the
5608 * xm-news.h (MISSING_VPRINTF): Add.
5610 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
5612 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
5614 * Remove stuff that forces -Bstatic linking of gdb, and warnings
5615 about linking debugged programs -Bstatic in the sun?os4 config
5616 files in tconfig and xconfig subdirectories.
5618 * main.c (main): Remove unreached exit(0) now that we exit
5621 * Create TODO file for online bug list. There are too many
5622 "little" bugs to keep track of on paper.
5624 * Change Projects file to refer to bug-gdb@cygnus.com
5625 rather than kingdon@ai.
5627 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
5629 * Makefile.dist (VERSION): 3.91.4 now.
5631 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
5632 (condense_misc_bunches): Add sanity check that misc_count is
5633 the same as the number of symbols in the bunch.
5635 * coffread.c: rename init_misc_bunches. Pass an argument
5636 to condense_misc_bunches (a zero).
5638 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
5639 every time we are called; don't rely on our caller to do it.
5640 (add_file): Remove call to init_misc_bunches.
5642 * mipsread.c: Only warn, don't error, if unknown symbol types.
5643 This keeps an old gdb from falling on its face if it sees newly
5644 extended symbol info. Rename init_misc_bunches.
5646 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
5648 * Merge in changes from Per Bothner for DECstations and other
5649 MIPS stuff. The rest is Bothner speaking:
5651 The next message is a merger of Alessando Forin's mips port with
5652 mine. I've tried to use my good if biased judgment to get
5653 the best of both. It *does* need testing.
5655 Some of the changes are general, *not* mips-specific.
5658 Didn't believe in little-endian bit order.
5659 There are still inconsistencies about whether flags
5660 like BITS_BIG_ENDIAN are integer (#if ...) or
5661 boolean (#ifdef ...). I tried to paper over them.
5663 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
5664 Moved some misc_function code that was common to
5665 {dbx,coff,mips}read.c to symtab.c.
5666 In the process, I think I cleaned things up a bit.
5667 At the same time, moved obsavestring and obconcat to symtab.c.
5670 Removed obsolete condense_addl_misc_bunches (use
5671 condense_misc_bunches(1) instead).
5674 Needed to include <sys/dir>, at least on DECstations.
5676 valops.c, mips-tdep.c, tm-mips.h:
5677 Added PUSH_ARGUMENTS macro to support funny argument-pushing
5678 conventions (when STACK_ALIGN is insufficient).
5679 Needed on mips, where doubles need 8-byte alignment,
5680 but ints only need 4.
5683 Removed cruft that was not being used.
5684 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
5687 Print $ before register-names (I think that makes things a little
5689 Never print two instructions, even if one delays.
5690 Removed hex-disassemble set_cmd. (This is not mips-specific,
5691 so I think the argument is whether it is generally worthwhile or not.
5692 I'm inclined to think not, given how easy it is to
5693 convert between radixes in gdb.)
5696 This is basically Alessando's code.
5697 It doesn't use obstacks; I changed it to use obstacks
5698 in a few minor places where using malloc causes a
5699 memory leak. (Probably, more places could/should be changed.)
5700 I added record_misc_function where it was missing.
5701 In symbol_file_command and add_file_command, I tried
5702 to make the code consistent with more recent versions.
5703 Minor sylistic changes in parse_procedure.
5704 Make a .gdbinfo. psuedo-symbol point back to the real
5705 procedure symbol (using the isym field).
5708 This is basically from my port, but with a lot of details
5709 and a number of routines merged in from Alessando's version.
5710 I basically used my code "raw" backtrace (use heuristics
5711 from the actual code, rather than symbol table info) - though
5712 the idea is Alessandro's. I feel my code is a little cleaner
5713 here, particularly in being a little more flexible, such as being
5714 able to handle gcc-produced code (which it now can).
5715 It also doesn't do frame caching (which is not useful
5716 more recent gdb versions).
5717 I also used my code for push_/pop_dummy, more or less.
5718 I tried to incorporate AF's code for testing sigtramp
5719 while backtracing; I probably got it wrong.
5720 Added mips_print_register, which tries to scrunch as much
5721 information as possible on a screen...
5722 Removed the skip-prologue set_cmd. As with hex-disassemble (see
5723 under mips-pinsn.c), I don't see anything mips-specific here,
5724 and I don't see it being all that useful anyway.
5727 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
5728 Use more register names (rather than hard-cases numbers).
5730 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
5732 * Hack up 3.90.11 changes:
5734 * Makefile.dist (depend): parameterize $(GCC).
5735 Add solib.c and solib.o.
5736 (readline): Fix vpath for both absolute or relative SRCDIR.
5738 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
5739 Also, let the part I didn't understand at least compile so
5740 I can test the rest. FIXME.
5742 * dbxread.c: Fix thinko using strcmp.
5743 (init_psymbol_list): declare static.
5744 (partial_symbol_file_open): Comment cleanups better, avoid
5745 cleaning up the string table since the caller will do that.
5746 Move the stat for mod time into symbol_file_command, temporarily.
5747 (There should be a mod time for each symbol file, eventually,
5748 to control its rereading. FIXME.)
5750 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
5751 SunOS, which gives error for shared libs otherwise. (From
5752 Schaefer, probably FIXME needs work for portability.)
5754 * solib.c: Move #include "param.h" to work.
5755 Lowercase all the Uppercase Letters In the Messages.
5756 (find_solib): Clean up inferior_so_name for debug printouts.
5757 Allow no argument, to mean all shared libraries.
5759 * symmisc.c: include param.h to get CLEAR_SOLIB.
5761 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)

5807 Take code which is shared between symbol_file_command and
5808 add_file_command and put it into partial_symbol_file_{open,read}.
5809 Split add_file_command into add_file_command and add_file.
5810 Make psymtab_to_symtab read in the string table if the file
5812 Two new parameters to read_dbx_symtab and start_psymtab.
5813 tm-sunos.h: New file.
5815 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)

5826 * values.c (USE_STRUCT_CONVENTION): Check for structures of
5827 size 1,2,4,8 rather than size < 8.
5829 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
5830 as necessary, not just once.
5832 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
5834 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5836 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386

5840 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
5842 * config.gdb: In list_host, list_target, use ${i}, not $i.

5851 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5853 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
5855 config.gdb: If srcdir != ., create readline directory and
5856 copy a makefile into it.
5858 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
5859 consistency with POSIX.
5861 * breakpoint.c (bpstat_stop_status): Disable watchpoint

5866 * Makefile.dist: Bump version to 3.91.3.
5868 * Clean up handling of breakpoint commands (somewhat).
5869 Prompted by Tiemann bug report "cont 10" doesn't work any more.
5871 inferior.h: Add breakpoint_proceeded to inferior status struct
5872 and globals; save it and restore it.
5873 (clear_breakpoint_commands): Cleanup, remove old #define.
5875 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
5876 (save_inferior_status, restore_inferior_status): handle it also.
5877 (proceed): Remove earlier code that set breakpoint_proceeded.
5878 It is now set only in clear_proceed_status.
5879 (clear_proceed_status): Cleanup, use bpstat_clear rather
5880 than clear_breakpoint_commands. No callers need the stop_bpstat
5881 between clear_proceed_status and proceed.
5883 infcmd.c: Add breakpoint_proceeded definition and comment.
5884 (cont_command, jump_command, signal_command): Move call to
5885 clear_proceed_status right next to call to proceed.
5887 breakpoint.c (bpstat_do_actions): Avoid clobbering our
5888 caller's argument while running down the chain of breakpoints.
5889 Use new variable "breakpoint_proceeded" to determine when
5890 a command that it executes moves the inferior past the
5892 (bpstat_clear): Handle NULL argument.
5893 (bpstat_clear_actions): Avoid useless call to
5894 breakpoint_auto_delete.
5895 (delete_breakpoint): Clean up bpstat's that are pointing to
5896 the deleted breakpoint from the stop_bpstat chain.
5897 (breakpoint_auto_delete): Simplify.
5899 * Clean up handling of EOF, error on stdin, etc. This was
5900 prompted by a network problem that caused gdb to go into an
5901 infinite loop filling up its malloc'd memory.
5903 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
5904 not clear_breakpoints_commands, which is now gone.
5905 (main): If command_loop returns (e.g. from EOF on stdin), do
5906 a quit_command (looping back to command_loop if quit_command
5907 doesn't really quit).
5908 (command_loop): check result from command_line_input and
5909 exit if it returns NULL, rather than passing the NULL to
5911 (gdb_readline): Free malloc'd result space before returning
5914 * utils.c (query): Handle C-d to mean "yes", just as if the
5915 input was not a terminal. Also avoid infinite loop if EOF
5916 occurs in mid-input-line before newline. This allows
5917 query to be used at EOF on stdin with reasonable results.
5919 * infrun.c (proceed): Set breakpoint_proceeded.
5921 * values.c (value_as_long): Avoid infinite recursion for enums.
5922 (_initialize_values): Fix typo in help msg (kingdon).
5924 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
5925 RL_LIB for linking. This allows -lreadline for linking
5926 and nothing for dependencies, once readline is a real library.
5928 * config.gdb: Jim Kingdon: give useful error message if the
5929 host or target type is not recognized.
5931 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
5932 it just defines it. Dumb, but deal with it.
5934 * Jim Kingdon suggests:
5935 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
5937 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
5939 * Makefile.dist (VERSION): Bump version # to 3.91.2.
5941 * Clean up Bothner's changes.
5943 * blockframe.c (clear_pc_function_cache): New function.
5944 * blockframe.c: remake cache_pc_function_* static.
5945 * dbxread.c (symbol_file_command): remove references to
5946 cache_pc_function_* variables.
5947 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
5948 * printcmd.c: Avoid kludging a global variable (addressprint)
5949 to avoid printing the address of a string twice. Instead,
5950 pass the format letter 's' down low enough that it can be seen
5951 to avoid this problem.
5952 (print_formatted): Pass format arg to value_print.
5953 (restore_addressprint): Remove function.
5954 (do_examine): Avoid hacking addressprint, cleanups and such.
5955 (print_frame_args): Add a comment to a Bothner change.
5956 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
5957 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
5958 to wipe out the values cached in blockframe.c.
5959 * symtab.c (find_method): Add comment saying how big you must
5960 allocate to be "big enough". Per being terse again.
5961 * valprint.c (val_print): Handle format letter "s" to print
5962 strings without addresses. Add comment to vtbl printing code
5963 which casts with wild abandon. Rearrange reference-printing
5965 @0xaddr: value (print w/addressprint)
5966 value (print w/~addressprint)
5967 @0xaddr (parameter lists w/addressprint)
5968 or nothing (parameter lists w/o addressprint)
5970 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
5972 * Merge more changes from Per Bothner:
5974 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
5975 annoying) that I tried to improve it. Here are my suggestions.
5977 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
5980 Do automatic de-reference when taking the address of a reference.
5982 Don't deref_ref when printing parameter lists.
5984 More attempts at treating refernences properly.
5986 In val_print, if deref_ref==0, don't print dangling " = ".
5988 Add COERCE_REF macro, which de-references an REF.
5990 * Merge changes from Per Bothner:
5992 * Fixed (Sony news)-specific configuration problems.
5993 * Fixed other problems with using vanilla pcc and libc (enum problems;
5994 assumption that vsprintf exists).
5995 * Some major speed-ups (finc_pc_partial_function now caches a match;
5996 parsing avoids duplicate symbol_lookup calls).
5997 * Changed handling of baseclasses (no longer use baseclasses field
5998 of struct type, use the first n_baseclasses fields instead).
5999 * Various minor changes/fixes, most C++-related.
6002 Cache the most previous match from find_pc_partial_function.
6003 (Save both low and high ends of matching function's pc range.)
6004 This speeds up the loop of infrun.c:wait_for_inferior quite
6005 a bit, and makes step/next commands much zippier.
6007 Added an enum->int cast (otherwise, some compilers barf).
6009 No longer set baseclass offset to 0, since multiple
6010 inheritance now mostly works.
6011 Added a number of casts, to shut up compiler warnings
6012 (after stabs where made enums, not ints).
6013 When discarding a symbol table (in symbol_file_command),
6014 must clear the cache introduced in blockframe.c.
6015 Don't convert $vtbl_ptr_type to vtbl any more.
6016 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
6017 Mask off sign bit emitted by g++ for virtual table offset.
6018 Set voffset to -1 (not 1) for static member functions.
6020 Changed parsing/lexing of names to avoid doing symbol lookup twice
6021 (once when lexing to determine symbol class, once for real).
6022 Now only call symbol_lookup once. Fields of 'this' win especially big.
6024 Subpress printing addr twice in the case of 'x/s addr'.
6026 lookup_basetype_type is no longer used.
6027 Add find_methods as recursive helper function to decode_line_1.
6028 This allows multiple inheritance to work.
6029 Also, once one or more matches has been found, do not look in
6030 base-classes. (Baseclass methods would be overridden, anyway.)
6032 Removed baseclasses array in struct type.
6033 Instead of using baseclasses[i], use fields[i-1].
6034 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
6035 Changed sign convention of voffset (previous was inconsistent).
6037 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
6039 Used to assume existence of vsprintf. Re-written to not need it
6040 if HAVE_VPRINTF is undefined.
6042 typecmp was too pessimistic. Made it less so.
6044 Don't print space after address.
6045 If vtable points to a misc symbol (with 0 offset), print it,
6046 since that indicates the actual class of the object.
6047 Changed ype_print_derivation_info to use new inheritance
6048 scheme (without baseclasses vector).
6050 In value_primitive_field, fixed some bugs left over from previous set of fixes.
6051 Also, changes needed because TYPE_BASECLASSES were removed.
6053 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
6055 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
6058 If there is no path set, and the symbols don't indicate what directory
6059 a file was compiled in, look in the current directory. But either
6060 a path or a known compilation directory will prevent this.
6063 Three independent bug fixes:
6064 * Remove the #if 0 block that breaks some stuff.
6065 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
6066 adapt gdb to either SunOS 4.0.* or 4.1.
6067 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
6070 Instantiate the class T when looking for methods in it. (Tiemann@sun)
6073 (type_print) Demangle the name being printed.
6074 (type_print_base) Handle botched demangling without coredump (tiemann).
6077 (check_stub_method): Document routine.
6078 (tiemann) fix bug for no-arg functions
6079 Avoid clobbering beyond end of malloc'd storage.
6080 Terminate the argument list properly.
6082 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
6084 * Changes merged by John Gilmore:
6087 In breakpoint_1, use new print_address_symbolic instead
6088 of find_pc_partial_function. (This forces use of assembler-level
6089 addresses, and avoids misleading non-mangled source-level names.)
6091 Generalize ansi argument such that -1 means skip arglist totally.
6092 Removed global variable print_ansi_qualifiers (which made
6093 code non-reentrant), in favor of extra explicit arguments
6094 to internal routines.
6096 Add new helper function print_address_symbolic.
6097 Use find_pc_misc_function instead of find_pc_partial_function
6098 (since we want assembler-level symbols here).
6100 Print unknown function as just "f (...)", not "f (...) (...)".
6101 Use new fputs_demangled explicitly.
6103 Fixed a typing violation (problem: value.h cannot be imported
6104 without renaming many variable in this file).
6105 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
6106 decode_line_1: Moved forward some never-reached code.
6107 Made decode_line_2 skip function prologues correctly.
6109 fputs_filtered should not demangle by default.
6110 Add new fputs_demangled to demangle on demand..
6112 Change value_struct_elt to use value_primitive_field (using recursive
6113 utility function search_struct_field). This allows foo.bar to work
6114 for multiple inheritance (so far only for data fields).
6115 Change check_field in the same way (recursive helper function
6116 to support multiple inheritance).
6117 (Note: there are more of these problems that I haven't fixed.
6118 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
6119 value_of_this: 'this' symbol name is now just "this", note "$this".
6121 Don't print static members.
6122 Avoid printing "members of <type>" if there are none.
6123 Simplified type_print_derivation_info by merging duplicate code.
6124 Remove useless blank lines in type_print_base (ptype command).
6126 Added declaration of new routine value_primitive_field.
6128 Added value_primitive_field which is generalized version of
6129 value_field that can handle multiple inheritance (non-zero offsets etc).
6130 Re-implemented value_field to call value_primitive_field.
6132 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
6134 * infcmd.c -- insert else to avoid 'delete env' coredump when you
6135 delete the whole environment. Karl Berry reported the bug.
6136 * source.c - fix openp to avoid //'s in filenames, which
6137 trigger an Emacs bug causing it to not be able to find files
6138 when running gdb in a window.
6139 * dbxread.c - zap the #if 0 that botches the add-file code.
6140 It seems to work a lot better without all the code commented out.
6142 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
6144 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
6147 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
6149 * Makefile - added a ${CFLAGS} to a couple of entries,
6150 added remote-sa.sparc.c
6151 * added remote.sa-sparc.c, a modification of remote.c
6152 which conducts a dialog directly with the SparcStation prom.
6153 * breakpoint.c, infrun.c, sparcdep.c added
6154 remote_insert_breakpoint(), and remote_remove_breakpoint()
6155 to breakpoint.c instead of directly writing breakpoint instructions.
6156 * sparcdep.c on remote_debugging,there is no need
6157 to remove signle step breakpoint instructions.
6158 * main.c added "-epoch" flag and "int epoch_interface" to main.c
6160 * printcmd.c - epoch interface sends lisp expressions to open up
6161 epoch windows on inspection.
6162 * valprint.c - added arrayprint, and addressprint and made adding
6163 format controls easier
6164 * wait.h added a couple of undef's because we were getting
6165 complaints about WSTOPSIG and WTERMSIG begin redefined.
6168 Wed Jul 4 05:27:51 1990 Michael Tiemann (tiemann at masham)
6170 * symtab.c (decode_line_1): Add support for handling method stubs

6175 * values.c (baseclass_addr): Run loop from INDEX+1 to
6176 N_BASECLASSES; otherwise, we can still get into a loop.
6177 @@ This should be restructured to use a cleaner search strategy.
6179 Sun Jul 1 12:28:51 1990 Michael Tiemann (tiemann at masham)
6181 * dbxread.c (define_symbol,read_type): Grok GNU C++'s new
6182 abbreviation "Tt" for tags which have the same name as their
6185 Fri Jun 29 01:03:46 1990 Michael Tiemann (tiemann at masham)
6187 * symtab.c (list_symbols): add ability to set breakpoints on all
6188 the functions which match a particular regular expression.
6190 Tue Jun 26 04:26:29 1990 Michael Tiemann (tiemann at masham)
6192 * cplus-dem.c (cplus_demangle): New parameter ANSI says whether we
6193 should print ANSI qualifiers (such as `const' and `volatile').
6194 All callers changed to call with ANSI == 1, except from
6195 `check_method_stub', which uses old-style syntax.
6197 * symseg.h (struct fn_field): Remove unneccessary `args' field.
6198 * symtab.h (TYPE_FN_FIELD_ARGS): Redefined.
6200 * values.c (check_stub_method): New function.
6202 * cplus-dem.c (do_type): Handle "long long" (encoded as 'x').
6204 * dbxread.c (read_type): Handle new GNU C++ method type stubs.
6205 * valprint (type_print_base): Ditto.
6207 * symtab.c (gdb_mangle_typename): New function.
6209 Tue Jun 5 00:18:43 1990 Michael Tiemann (tiemann at gzilla)
6211 * breakpoint.c (catch_command): New function. Provides a
6212 mechanism to set breakpoints based on catch clauses.
6213 (disable_catch): Similar, but disables breakpoints on catch
6215 (delete_catch): Similar, but deleted breakpoints on catch clauses.
6217 Sun Jun 3 22:54:08 1990 Michael Tiemann (tiemann at gzilla)
6219 * blockframe.c (blockvector_for_pc): New function.
6220 * blockframe.c (block_for_pc): Changed to call
6221 `blockvector_for_pc' and get the block itself.
6223 * stack.c (catch_info): New function. Prints info about
6224 exceptions which can be caught in the current frame.
6225 * stack.c (print_frame_label_vars): New function. Similar to
6226 `print_frame_local_vars'.
6227 * stack.c (print_block_frame_labels): Prints out labels that are
6228 defined in this frame. These labels are exceptions that can be
6231 * dbxread.c: Updated to handle N_CATCH symtab types.
6233 Thu May 3 22:10:00 1990 Michael Tiemann (tiemann at teacake)
6235 * valprint.c (everywhere): TYPE_NAME (TYPE) no longer comes in the
6236 form "struct ..." for GNU C++. Don't flush any part of TYPE_NAME
6237 when printing the type.
6239 Wed May 2 22:43:04 1990 Michael Tiemann (tiemann at teacake)
6241 * valprint.c (val_print): Use `baseclass_addr' to access the
6242 baseclasses pointed to via the derived class object at VALADDR.
6244 * values.c (baseclass_addr): New function. Casts derived pointers
6245 to baseclass pointers taking virtual baseclasses and multiple
6246 inheritance into account.
6248 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6252 Fri May 4 12:12:55 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6254 * breakpoint.c (watch_command, bpstat_stop_status): Deal with
6255 exp_valid_block field correctly.
6257 * infrun.c (wait_for_inferior): When checking "don't even think
6258 about breakpoints" if stop_signal == SIGTRAP && trap_expected,
6259 also check step_resume_breakpoint.
6260 Insert breakpoints and continue (not step) if
6261 step_resume_break_address != NULL, even if another_trap.
6262 If trap_expected and we enter sigtramp, then set up a
6264 If trap_expected is set when we hit the step_resume_break,
6266 When calling resume and trap_expected says tell resume to step
6267 (2 places), also check step_resume_break_address.
6269 * infrun.c (wait_for_inferior): Don't set
6270 prev_{pc,sp,func_{start,name}} before calling wait ().

6278 Restore old code which distinguishes between trap_expected and
6279 running_in_shell, just make the latter take any non-TRAP signal,
6282 * values.c (allocate_value): Zero VALUE_OPTIMIZED_OUT flag.
6284 * Makefile.dist (pinsn.o): Use PINSN_CC to compile.

6344 findvar.c (get_saved_register): New function.
6345 findvar.c: Rewrite code which called find_saved_register to
6346 call get_saved_register instead.
6348 Sun Apr 22 14:47:51 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)

6388 m-m88k.h: Use INIT_{FRAME_PC,EXTRA_FRAME_INFO} to do tdesc stuff.
6389 Use dummy versions of FRAME_CHAIN_*.
