195 been read in, particularly for VxWorks.
197 * dbxread.c (read_dbx_symtab): Allow N_SOL to cleanly take us back

201 new psymtab for it has been read.
202 * coffread.c (end_psymtab): Free named symtabs and psymtabs for
203 a file, once a new symtab has been read for it.
204 * mipsread.c: FIXME. We need to do the same for MIPS, but it
205 looks harder to determine the top-level block before it's been
206 queued to the psymtab list.
208 * symfile.c (symbol_file_add): Use filtered printing and wrap it.
209 If we have wiped out any old symbol tables, clean up at end of
211 (symbol_file_command): Don't reference symfile_fns if it's zero.
213 * symtab.h (GLOBAL_BLOCK, STATIC_BLOCK, FIRST_LOCAL_BLOCK): New
214 defines for the blocks of a blockvector that contain global and
215 file-static symbols and the first of the smaller scope contours.
216 * symtab.c (lookup_symbol, find_pc_symtab, find_pc_line,
217 decode_line_1, make_symbol_completion_list): Use the above.
218 * coffread.c (end_symtab, patch_opaque_types): Ditto.

230 Thu Apr 11 05:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
232 * m68k-stub.c: Remote stub for 680x0's, created from

235 Remove RCS log stuff now that we use CVS and it blows our diffs.
237 Thu Apr 18 18:08:30 1991 John Gilmore (gnu at cygint.cygnus.com)
239 * symfile.h (free_named_symtabs): Rename from free_named_symtab.

259 new psymtab for it has been read.
260 * coffread.c (end_psymtab): Free named symtabs and psymtabs for
261 a file, once a new symtab has been read for it.
262 * mipsread.c: FIXME. We need to do the same for MIPS, but it

264 queued to the psymtab list.
266 * symfile.c (symbol_file_add): Use filtered printing and wrap it.
267 If we have wiped out any old symbol tables, clean up at end of
269 (symbol_file_command): Don't reference symfile_fns if it's zero.
271 * symtab.h (GLOBAL_BLOCK, STATIC_BLOCK, FIRST_LOCAL_BLOCK): New
272 defines for the blocks of a blockvector that contain global and
273 file-static symbols and the first of the smaller scope contours.
274 * symtab.c (lookup_symbol, find_pc_symtab, find_pc_line,
275 decode_line_1, make_symbol_completion_list): Use the above.

297 * symmisc.c (free_named_symtab): Make it work, in its current
298 kludgy fashion. Change result to indicate if we blew away bkpts.
299 * dbxread.c (end_symtab): Accumulate result from
300 free_named_symtab and print warning if we blew user's state.
301 * symfile.h: free_named_symtab now returns an int.
303 Mon Apr 8 23:57:43 1991 John Gilmore (gnu at cygint.cygnus.com)
305 * dbxread.c (dbx_symfile_read): Initialize psymbol list if this
306 is the first symbol read, even if not mainline.
307 (dbx_psymtab_to_symtab): symfile might be zero, cope.
308 * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
309 (set_section_command): New command ("section xxx yyy" -- should
310 be renamed to "set section xxx yyy" FIXME) which sets the
311 base address of a section of the exec file, overriding the
312 virtual address that BFD reports.
314 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
316 * exec.c: Add add_syms_addr_command to exec_ops, so you can
317 load symbols at any address while examining an exec file.
319 Thu Apr 4 10:09:35 1991 John Gilmore (gnu at cygint.cygnus.com)
321 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
322 for printing the float info is host-dependent, not
323 target-dependent. FIXME.
324 * i386-pinsn.c: Move #includes to top, remove useless ones.
325 * i386-tdep.c: Don't bother including <.../reg.h> since we
326 don't use it (and it doesn't exist on host systems).
328 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
329 Convert negative numbers properly.
330 (ieee_test): Make numbers really random; fix format arg.
332 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
333 * core.c (core_detach): Unpush core_ops, which might not be on
334 top. We used to just pop the top, which broke things. Don't
335 need dont_repeat() any more.
336 (core_file_command): Psst! Don't repeat it.
337 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
338 * expprint.c (print_subexp): Avoid switch fallthru on
339 BINOP_ASSIGN_MODIFY, so we can print += and such.
341 * inflow.c (kill_command): After killing inferior, print our
342 current frame in the core file, if we have one.
343 (generic_mourn_inferior): When inferior dies, either select
344 the current frame (in the new target, e.g. core file), or
345 set both the current and selected frames to NULL.
347 Changes from Peter Schauer.
349 * infptrace.c: Avoid <sys/ptrace.h> on USG.
351 * Make all file names fit in 14 characters (sigh and damn!):
352 mv hp300hpux-xdep.c hp300ux-xdep.c
353 mv symmetry-xdep.c symm-xdep.c
354 mv symmetry-tdep.c symm-tdep.c
355 mv convex-opcode.h convx-opcode.h
356 mv tm-vxworks960.h tm-vx960.h
357 mv tm-vxworks68.h tm-vx68.h
358 mv Makefile.srcdir Makefile.sdir
359 mv gdb-int.texinfo gdbint.texinfo
360 mv remote-sa.m68k.shar rem-m68k.shar
361 mv remote-multi.shar rem-multi.shar
362 * Makefile.dist, README, config.gdb, convex-pinsn.c,
363 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
364 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
367 * command.c (user_info_1, user_info): New command for listing
368 the user-defined commands.
370 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
372 * dbxread.c (really_free_pendings): Clear file_symbols
373 and global_symbols after freeing them; otherwise, running
374 this function twice (if it appears twice on the cleanup
375 chain), we try to free things twice.
377 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
378 based on text_addr (the address of text in core), not on addr (the
379 offset between text in the .o file and in core). This change
380 is from Peter Schauer.
382 * main.c: Define ALL_CLEANUPS as a cast of zero.
383 (return_to_top_level): Use it.
384 (main): Do all cleanups after each command run as part
385 of the gdb startup sequence. Also do all cleanups before
386 entering the command loop, and every time we exit the command
387 loop and reenter. Before, the cleanups from the startup sequence
388 were being left undone until the first error!
389 (command_loop): Rename do_nothing cleanup to command_loop_marker
390 so we can see it easily when examining the cleanup chain.
391 (init_signals): Add another do_nothing for signal handling.
392 (quit_command): Only try to kill target if it has execution.
393 Problems in the target stack got us into a state where
394 inferior_pid was nonzero but none of the targets had execution.
395 In this state you couldn't exit gdb.
397 * dbxread.c: Two changes from Peter Schauer.
398 (echo_command): Fflush output after an echo command.
399 (show_history): Pass all args to cmd_show_list.
401 * utils.c (init_malloc): Call mtrace to turn on tracing
402 if the environment variable MALLOC_TRACE is set to a file name.
403 * mtrace.c: Add source file which provides a log of every malloc,
404 free, and realloc to a trace file.
405 * mtrace.awk: Add source file which analyzes the trace file.
406 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
407 (VERSION): Roll to 3.94.3.
409 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
410 (check_duplicates): Don't bother with watchpoints.
411 (set_raw_breakpoint): Comment about danger of this routine.
412 (watch_command): Parse and eval all args before calling
415 * solib.c (find_solib): Avoid error in referencing memory to
416 see if any more shared libraries have been added. This is
417 particularly useful if the target has terminated. Bug reported
420 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
421 in bringing up 3.94.2 on the Sun-3.
423 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
424 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
425 expression (in scope) before reenabling watchpoint.
426 * signame.c (init_sigs): Add missing declaration of i, fix
427 sys_siglist declaration.
428 * source.c (list_command): Fixed range computation to use
430 * stack.c (backtrace_command): Do not allow command if target has
431 no stack, print informative error message.
432 * target.c (target_command): Do not write into command line
433 because this fails if the target command is used in a user defined
434 command. [This change was enhanced by gnu to support any-
435 unique-prefix matching on target names.]
436 * valops.c (value_struct_elt): Avoid infinite loop on an
437 erroneous attempt to print the member of function (try p main.p).
439 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
441 * expread.y (name_no_typename): Avoid reduce/reduce errors
442 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
443 Since the GDB parser really doesn't use name_no_typename in a
444 name-only context, the parser can't tell the diff between
445 names and numbers here. Avoid allowing a name_no_typename
446 to be a NAME_OR_*INT to resolve the conflict.
448 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
450 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
452 * valprint.c (val_print_fields): bitfield printing didn't handle
453 byte order. Indirect through a few more fns to cope.
455 * values.c (modify_field): also cope with byte order.
457 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
459 Cleanup for release 3.94.2:
461 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
462 include files. Roll version to 3.94.2.
464 * coffread.c (init_stringtab): Read length into unsigned char
465 array before swapping; don't assume 32-bit longs.
467 * target.c (target_info): Don't bother with get_sym_file, just use
468 the symfile global variable.
469 * symtab.h, symfile.c (get_sym_file): Delete it.
471 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
472 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
473 (read_type): Replace one more error() with complain().
475 * mipsread.c (parse_partial_symbols): Replace printf with complain.
477 * i960-tdep.c: Fix copyright attribution.
479 * config.gdb: Quote all backquotes in doublequotes. You can
480 quote me on that. BSD 4.4 shell found this one.
482 * infptrace.c (throughout): The third argument to ptrace is an
485 * infrun.c (wait_for_inferior): When program has terminated, we
486 have to call target_terminal_ours before we pop that target off
487 the stack (e.g. before a call to target_kill or
488 target_mourn_inferior). This fixes problem where a program
489 terminates, then GDB stops for (tty output) and you have to type
490 "fg" to the shell to resume it. FIXME: This code for what to
491 do after termination really should be in normal_stop instead.
493 * gdbcore.h (read_memory_check): Change declaration; it changed
496 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
497 4.4 prereleases, this avoids a bug in their sgtty compatability
499 * remote.c: Use terminal.h rather than hand-rolling the same.
501 * signame.c, signame.h (psignal): Arg is unsigned, not int.
502 * utils.c (strsave, strstr): Fix arg types.
503 * valprint.c (val_print): lint
505 MIPS symbol table support from Per Bothner:
507 * symfile.c (symtab_fns): Remove initializer table that needs to
508 be hacked for each new symbol file format supported.
509 (add_symtab_fns): New function, chains symbol table
510 handlers into the global list.
511 (symfile_init): Search this list.
512 * symfile.h: Add next pointer, declare add_symtab_fns.
513 * coffread.c (_initialize_coffread): Call add_symtab_fns.
514 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
516 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
517 symbol *). Thus, we no longer need the hack to trash
518 pst->filename. Good, since that hack confused code in symfile.c!
520 (reorder_symtabs, destroy_all_symtabs): Removed static
521 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
522 Instead, the latter now uses a temporary array (stack-allocated
523 from an obstack, and then freed).
525 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
526 haven't been set in the outermost stBlock of a procedure. This was
527 a problem with f77 binaries on Ultrix 4.?.
529 (new_symtab, new_symbol, new_type): Continue changing code to use
530 obstacks more and otherwise conform to dbxread internal style.
531 Made the free_code of symtabs be free_linetable (as in dbxread)
532 instead of free_contents. This implies memory leaks when reading
533 a new symbol table, until the conversion is finished. Did change
534 (struct symbol) and (struct type) to be allocated on the
535 symbol_obstack. Blocks and blockvectors are among the things
538 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
539 tested much, but it solved one problem (reported by Meissner), and
540 cleans up some other things. The problem happened when an
541 included file contains actual code (functions) and not just
542 definitions. The mips coff is a little inconvenient there, since
543 it may cause a procedure to be mapped to the wrong psymtab.
545 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
546 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
547 this will need work for the new core paradigm.
549 Opcode patches from the net:
551 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
552 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
553 missing altogether - they are added here. From Bruce Bauman.
554 * mips-opcode.h: The low mask for C0 instructions was too small.
555 From Garrett Lau. I modified the fix to check the entire 32-bit
558 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
561 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
563 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
565 * dbxread.c (read_type): Pointer subtraction (value_sub in
566 valarith.c) sometimes failed because the types of the
567 pointers being subtracted were not identical.
568 These differed because dbxread.c was allocating pointer types
569 using dbx_alloc_type+smash_to_pointer_type instead of
570 lookup_pointer_type. I failed to find a justification for the
571 former, so I changed it to use the latter. Similarly, I
572 replaced smash_to_function_type by lookup_function_type,
573 and smash_to_reference_type by lookup_reference_type.
575 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
576 _initialize_mipsread): corresponding changes.
578 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
580 * source.c (mod_path): Do tilde_expand on each component of the path,
581 rather than on the (list of) paths as a whole.
582 (print_source_lines): Set first_line_listed in addition to
583 current_source_symtab and current_source_line. If the source was
584 not findable, after a "dir" command to fix the problem,
585 a "list" would get the wrong lines.
587 While I was there... (gnu):
589 * dbxread.c (read_type): Change error to complaint.
591 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
593 First attempt at detailed understanding of symbol table memory alloc.
595 * dbxread.c (dbx_symfile_read): Free our string table if we
596 aren't the mainline. Free the "info" struct since we're done with
598 (init_psymbol_list): Free any previously allocated psymbol lists.
599 (): FIXME: Should realloc-down the psymbol lists when done reading
600 the main symbol file?
602 * symmisc.c (free_symtab): Free fullname field too.
604 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
605 (REGISTER_ADDR): Make result type unsigned int.
607 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
608 define REGEX must also define REGEX1 (its dependency).
610 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
612 * tconfig/i960: No longer works, points you at vxworks960 or
615 * xgdb.c, XGDB-README: Remove file. Users can get the much
617 * Makefile.dist: Remove all trace of xgdb.
619 * breakpoint.c (breakpoint_1): Pass demangle arg to
620 print_address_symbolic.
621 (clear_breakpoints): Remove unused function.
622 (breakpoint_re_set_one): Guts of breakpoint_re_set.
623 (breakpoint_re_set): Use catch_errors to do them all anyway.
625 * gdb-int.texinfo (Host versus Target): Add section on what is
626 a "host" feature versus what is a "target" feature.
628 * infcmd.c (path_command, path_info): Handle the PATH variable
629 (object search path) as conveniently as the source search path.
630 * environ.c (set_in_environ): Set some vars in GDB's environment,
631 in addition to the child's. PATH, G960BASE, G960BIN for starters.
632 * source.c (mod_path): New function, from guts of
633 directory_command, modifies a path. Used by path_command.
634 (directory_command): Call it.
635 * defs.h (strsave): Declare.
637 * utils.c (sevenbit_strings): Add new printing option.
639 (strsave): Provide this handy helper routine.
640 (set_width_command): Rename set_screen_width_command.
641 (_initialize_utils): "set screen-width" => "set width";
642 "set screen-height" => "set height"; add sevenbit-strings.
644 * infcmd.c (do_registers_info): Print floating point registers
645 in raw hex as well as float format, regardless of whether it is
646 a "virtual" convertible register.
647 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
648 regs as a double, just in case it's being used that way.
649 * values.c (unpack_long): Comment on array/function coercion.
650 (unpack_double): Argument is in target byte order now. For
651 integer arguments, just call unpack_long and float the result.
652 * m68k-tdep.c: include defs.h for "const" handling.
653 * remote-nindy.c: Use ieee-float stuff.
654 (nindy_fetch_registers): Unpack double regs to host double, then
656 (nindy_store_registers): Pack extendeds to host double, flip
657 around by misusing unpack_double, send as target double.
659 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
660 zero, as when stopped at the first instruction of a process.
662 * blockframe.c: Fix filename in comment (param.h => tm.h).
663 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
664 * tm-68k.h: Fix typos.
666 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
668 Changes from a bringup on the DEC Vax under Ultrix 4.0.
670 * coredep.c (fetch_core_registers): Pass end-address of register
671 section to register_addr as expected. Don't call supply_register
672 if we'd just pass it garbage.
674 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
676 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
678 * target.c (push_target, target_info): Cast enums to int for < or
681 * stack.c (print_frame_info): Identify source file & line
682 even if we can't print it.
684 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
686 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)

695 sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
696 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
697 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
698 double_to_ieee_extended.
699 * i960-tdep.c: Define ext_format_i960.
700 * m68k-tdep.c: Define ext_format_68881.
701 * sparc-tdep.c: Define ext_format_sparc, though unused.
702 * Makefile.dist (HFILES): Add ieee-float.h.
703 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
706 Obsolete the "coffstrip" program in favor of using BFD's strip.
708 * nindy-share/coffstrip.c: Remove file.
709 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
710 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
711 * tconfig/nindy960: Remove reference to coffstrip.o.
713 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
715 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
717 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
718 * dbxread.c: Remove static symfile_bfd.
719 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
721 * inftarg.c (child_detach): Pop the child_ops vector if the
722 detach is successful.
723 * remote-nindy.c (nindy_create_inferior): Don't push a new
724 nindy_ops since nindy uses the same one for execution and memory
726 * core.c (core_ops): Use child_attach and child_create_inferior
727 rather than default attach and create_inferior functions.
729 Handle floating point registers in core files.
731 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
732 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
733 This version untested since BFD doesn't yet support sun3 core
735 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
736 conventions. Fix comments and style. This version has not
737 been compiled yet, since we have no HP inhouse.
738 * core.c (get_core_registers): Look for two sections, ".reg"
739 and ".reg2", and pass both to fetch_core_registers sequentially.
741 Revise directory path yet again.
743 * source.c (forget_cached_source_info): Not static any more.
744 (init_source_path): New default source path is "$cdir:$cwd".
745 (dir_command): Handle variable arguments ($cdir, $cwd).
746 (source_info): Print "Compilation directory" rather than
747 "Originally compiled in" to remind people of $cdir.
748 (openp): If the path contains $cwd, use current directory.
749 (open_source_file): If compilation directory is known, replace
750 first $cdir in path with the compilation directory.
751 (print_source_lines): Even if we can't print the lines, set the
752 current symtab and line for future commands like "info source" or
753 "breakpoint". Also, error message now contains the file name,
754 line number, and file access error message.
755 (_initialize_source): Fix help text to describe changes.
756 * main.c (cd_command): Forget cached source info when we chdir.
757 * utils.c (strstr): Add simple implementation.
759 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
761 * coffread.c (read_one_sym, init_linetable, init_stringtab):
762 Byte-swap COFF symbol tables if necessary when reading them in.
763 Use complain() to replace error message in one spot. Needs
764 corresponding change in bfd/coff-code.h to make some symbol
765 swapping routines non-static.
767 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
769 Merge changes from Eirik Fuller, for UTek.

774 i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,
775 remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,
776 symmetry-tdep.c, symmetry-xdep.c, umax-xdep.c, utils.c: Eliminate
777 declarations of errno.
779 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
781 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
782 <rpc/rpc.h> and <rpc/types.h>.
784 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
786 * i960-tdep.c (examine_prologue): Add new argument limit,
787 which stops the scan at the end of the prologue, or at the PC.
788 This fixes a problem where it walks down into the code for the
789 user's statements if that code looks like function prologues.
790 Mark Fox and I have been bouncing this code back and forth, making
791 small changes to it. Callers changed to match.
793 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
795 Cleanup for gdb-3.94 release final:
797 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
798 the .c files from vx-share and nindy-share, from the various
799 macros, since they are not found via ALLDEPFILES.
800 (SFILES): Add tm-i960.h.
801 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
802 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
804 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
805 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.
807 Mon Feb 25 16:02:35 1991 Cygnus John Gilmore (cygnus at oldman)
809 * am29k-tdep.c: Add contribution line.
810 (examine_prologue): Cache information about function prologues in
811 the misc-function-vector to avoid lots of references over the
812 serial line while examining instructions.
814 * core.c (core_close): New function made from cleanup_core.
816 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
817 remote-vx.c, remote.c, target.c, target.h,
818 Update target_ops vector to add attach, close, and load entries.
819 Use add_syms_addr_command, not add_file_addr_command, for
820 add_file. Break out close routine from existing code.
822 * dbxread.c (really_free_pendings): Don't free pending_blocks;
823 they are in an obstack.
824 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
826 (define_symbol): Add symbol type parameter; change callers;
827 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
828 it to influence the symbol class on the i960.
829 (define_symbol): Swap LOC_CONST's into target byte order.
831 * exec.c (exec_close): New function.
832 (exec_file_command): Call it.
834 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
835 Fix byte order of frame pointer.
836 (read_var_value): Result of 0 if var's value can't be found,
837 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
838 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
839 (locate_var_value): Use read_var_value and use its lazy address
840 as the location of the var's value. Lint.
842 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
845 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
846 obsolete Intel versions in favor of vxgdb versions.
847 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
848 code dealing with byte order of values, which Intel did in host byte
849 order rather than gdb-4's target byte order.
850 (i960_frame_chain_valid): Move to nindy-tdep.c.
851 (examine_prologue, skip_prologue, frame_find_saved_regs,
852 frame_args_address, leafproc_return, saved_pc_after_call,
853 pop_frame): Add vxgdb versions from Mark Fox.
854 (examine_prologue, frame_struct_result_address): Add code
855 to deal with the saved value of G13 (struct return address
857 (frame_args_address): Modify Mark's version to prefer the
858 saved value over the current value in the topmost frame.
859 Cache result in the frame info to avoid performance hair in
861 (print_fault): Add gdb960 code for printing faults.
862 (_initialize_i960): Actually call check_host.
864 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
865 add stub routines. FIXME, these currently just return zero!
867 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
868 (attach_command): Call target_attach, not target_open, now.
870 * infrun.c (normal_stop): Make global, not static, for vx_attach.
871 (child_attach): Rename from child_open.
872 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
873 don't confuse it with a zero step_resume_break_address.
875 * inftarg.c (child_detach): Eliminate inferior_pid test.
876 (child_files_info): Clean up message a bit.
877 (child_ops): Use child_attach, not child_open, to attach.
879 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
880 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
881 findvar.c to here, since it depends on the contents of the
882 shadow_contents of breakpoints, but keep if #if 0 since it is
885 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
888 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
889 (ptype_command, display_command): Eliminate have_inferior_p and
890 have_core_file_p in favor of target_has_stack or
891 target_has_execution.
892 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
893 code for actually finding the values of arguments, though we still
894 keep track of the maximum stack offset for use in printing unnamed
895 arguments. Handle missing FRAME_ARGS_ADDRESS.
897 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
898 (struct nindy_regs): Define registers passed to/from nindy.
899 (nindy_fetch_registers, nindy_store-registers): Translate between
900 nindy and GDB formats for the registers.
901 (dcache_init): Statically allocate the cache, since it was being
902 allocated by a malloc that was never freed anyway.
903 (nindy_create_inferior): Error, not core dump, if no exec file.
904 (nindy_before_main_loop): Use target_load, not target_add_file.
906 * remote-vx.c (net_load): Specify large timeout for load
907 requests. Allow user to break out with INTERRUPT.
908 (net_break): Remove useless code, clean up. Change callers.
909 (parse-args, skip_white_space, find_white_space): Clean up arg
910 parsing to cope with quoted strings.
911 (net_wait, net_quit): Never call error, just return status.
912 (vx_read_register, vx_write_register): Cleanup status checking.
913 #ifdef the code based on which CPU we are using (960 or 68k),
914 FIXME, this should be completely general but it isn't yet.
915 (vx_xfer_memory, vx_resume): Cleanup status checking.
916 (vx_run_files_info): Improve message.
917 (vx_load_command): Renamed from vx_add_file_command. Allow load
919 (net_ptrace): Remove unused routine.
920 (vx_wait): Adopt code from vxgdb960 to cope with broken
921 connections to target machine and prompt to disconnect. Remove
922 debug printouts. Map some EVENT_'s to SIGnals.
923 (add_symbol_stub, vx_open): Print names of object files we found,
924 and "ok" if we read their symbols OK. Clarify output in general.
925 (vx_attach, vx_detach, vx_kill): Add these commands.
926 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
927 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
928 "info files" output, and create_inferior, since we already have
931 * stack.c (frame_info): Replace Frame_unknown with 0.
932 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
933 (return_command): Pop until the PC matches as well as the FP,
934 so it works even if the FP is shared with another function,
935 as in "frameless" or "leaf" procedures.
937 * symfile.c (load_command): renamed from add_file_target_command.
938 (add_syms_addr_command): renamed from add_file_addr_command.
939 (add_syms_command): Stub to call target_add_syms.
940 (_initialize_symfile): Change command names and descriptions,
941 add-file => add-syms, and load from alias to its own command.
943 * target.c (kill_or_be_killed, maybe_kill_then_attach,
944 maybe_kill_then_create_inferior): Default for attempts to start
945 a process, if one is already running, is to ask about killing
947 (upstack_create_inferior): #if-0 it, strata obsolete it.
948 (push_target, unpush_target, pop_target): to_close() a target
949 before unstacking it.
950 (target_info): Renamed from target_files_info.
951 (_initialize_targets): Rename "i files" as "i target", accessible
954 * target.h: Improve comments about the target_ vectored routines.
956 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
957 Convert commenting style to standard GNU style.
958 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
959 (SKIP_PROLOGUE): No longer a no-op.
960 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
961 (*_REGNUM): Sort register numbers.
962 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
963 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
964 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
965 are now 10 byte extendeds, not 8 byte doubles.
966 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
967 for nindy versus vxworks targets. FIXME, this should possibly go
968 in the target vector.
969 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
970 frame_saved_regs and arg pointer with each frame.
971 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
972 (FRAME_ARGS_ADDRESS): Use cached result.
973 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
974 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
975 (PRINT_RAMDON_SIGNAL): Call print_fault.
976 (POP_FRAME): Now works.
978 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
979 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
980 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
981 (ADDITIONAL_OPTION_HANDLER): use target_load, not
984 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
985 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
987 * valarith.c (value_subscripted_rvalue): Avoid handling
988 floats and doubles specially; it gave alignment errors. Lint.
990 * valops.c (value_of_variable, value_of_this): Error if unknown
993 * valprint.c (print_floating): Bcopy rather than pointer-deref,
994 to avoid alignment problems.
995 (value_print): Handle unknown value address.
996 (cplus_val_print): Two args are ignored; remove them. Change caller.
997 (val_print): Use unpack_long rather than pointer-deref.
1000 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
1001 to avoid alignment problems.
1002 (value_being_returned): Error if return value unknown.
1003 (set_return_value): Add bogosity warning, FIXME. *
1005 * TODO: A woman's work is never done.
1007 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
1008 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
1009 Add ieee-float.o to OBS.
1010 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
1011 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
1012 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
1014 Changes to generalize the VxWorks RPC protocol slightly, to handle
1015 i960 as well as 68000.
1017 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
1018 * vx-share/reg.h: Produce i960 regs #ifdef I80960
1019 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
1020 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
1021 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
1022 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
1023 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
1024 so they will move in target byte order rather than network
1025 byte order (happens to be the same).
1027 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
1029 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
1031 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
1034 Add contribution lines to various files, showing where they
1037 * breakpoint.c (break_insn, check_break_insn_size,
1038 read_memory_nobpt): Remove to mem-break.c.
1040 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
1043 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
1044 entry has bad register number. This change is not
1045 tested in this release, FIXME.
1047 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
1050 * value.h: Force value's contents field to be aligned to hold
1051 at least a double or a long long (if supported). This avoids
1052 doing bcopy's in and out of the contents field.
1054 (step_1): Avoid coredump under obscure circumstances when we
1057 * symtab.h (misc_info): Add field to misc function vector for
1058 any kind of cached information the target code desires. AMD
1059 29000 uses this to avoid repeating examine_function_prologue's.
1061 * coffread.c: Lint. Remove static symfile, read_section_header.
1062 core.c (have_core_file_p): Lint: remove.
1063 expprint.c (print_subexp): Lint.
1064 infptrace.c, valops.c, valprint.c: lint.
1066 Roll in changes from vxgdb-5.0.1:
1068 * symtab.h: Comment byte order of each address class. Add
1069 LOC_LOCAL_ARG for frame-relative args (960).
1070 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
1071 symtab.c, symmisc.c: ditto.
1073 * infrun.c (init_wait_for_inferior): Clear stop_signal.
1075 * remote.c (remote_resume): Error if resume with a signal.
1077 * symfile.c (prim_record_misc_function): Clear misc_info.
1078 (fill_in_vptr_fieldno): Check stub type of arg.
1080 * valops.c (value_cast): Avoid looking up names of types whose
1081 name we don't know, to prevent coredump. Sun CC produces typedef
1082 rtx and the name of *rtx is zero...
1084 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1086 Roll in changes from final AMD 29000 port (Tiemann).
1088 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
1089 for ../include/a.out.encap.h. This might not work now that BFD
1090 is separately compiled. Instead, BFD support for encap will have
1091 to translate machine type 29k into the right COFF_MAGIC.
1093 * infcmd.c: Remove references to inferior_pid that aren't used
1094 in actual ptrace calls; use target_has_execution, etc.
1095 (have_inferior_p): Remove function.
1096 (program_info): Print target info rather than "process number";
1097 avoid gratuitous messages unless from_tty.
1098 (run_stack_dummy, finish_command): Set proceed_to_finish.
1099 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
1100 main.c: Lint. Lose have_inferior_p().
1101 inferior.h (have_inferior_p): Remove, lint.
1102 (proceed_to_finish): Add flag to ask that all regs be saved
1103 by normal_stop, for the few commands that need it, speeding up
1104 serial I/O. Add comments to stop_registers.
1106 * remote-eb.c: Remove newline from breakpoint message we grep
1107 for. Never time out when running the user program.
1111 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
1113 Roll in changes from vxgdb-5.0.1:
1115 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
1116 symbol in its raw form, we are processing an unlinked ".o" file.
1117 See if the target environment has assigned it an address, using
1118 target_lookup_symbol (VxWorks does), and enter it into the symtab
1121 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
1122 68k versions for a simpler version that assumes zero FP at bottom.
1123 Fixes bug of truncated stack reports.
1125 * target.h (target_lookup_symbol): Define this routine's args
1126 and result, finally.
1128 * target.c (nosymbol): Default routine for target_lookup_symbol.
1129 (target_default): Default lookup_symbol and call_function too.
1130 (files_info): Only print has_all_memory warning if a non-dummy
1133 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
1134 vx_convert_from_virtual): If target does not have floating point,
1135 zero register "values", and avoid doing cross-net conversions.
1136 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
1137 (vx_open): Rearrange code that attaches to target and reads
1138 symbols for all loaded modules, to work if some of the modules
1139 are not accessible. Add symbol_stub() and add_symbol_stub()
1140 as callbacks from catch_errors(). Allow connect attempt to be
1141 interrupted painlessly with ^C (FIXME, there are still some bugs
1142 if the interrupt happens during symbol reading.). Print
1143 final message with puts_filtered, since symbol messages are
1148 * main.c (catch_errors): Only print errstring if non-null.
1149 (command_loop): Avoid an ioctl per command to test ISATTY.
1151 * remote-vx.c (net_load): make static; avoid sophomoric msg.
1152 (vx_xfer_memory): Return correct result!
1153 (vx_files_info): Indicate whether target has float or not.
1154 (vx_lookup_symbol): Complain, not error, if target gone.
1155 (vx_open): Print "Connected" msg before disabling immediate-quit.
1156 [FIXME: lookup_symbol and vx_open changes need testing.]
1158 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
1159 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
1160 contributor lines and update copyrights to 1991.
1162 Changes from an attempted H-PUX host port:
1164 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
1165 defines PT_ATTACH and PT_DETACH but not PT_KILL.
1166 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
1167 * remote-vx.c: include <sys/time.h> for HPUX.
1168 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
1169 "core_file_command" routine to BFD regime. May not work yet.
1171 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
1173 * xgdb.c: Replace X10 version with some VJ version.
1174 (FIXME: Its copyright assignment is not on record.)
1175 * xgdb.c: Update include files to X11R4 (Xaw crud).
1176 (xgdb_display_source, create_text_widget): fix call to
1177 get_filename_and_charpos. Rewack source window stuff for X11R4
1178 (gleaned from include files, and "nm's" of binary libraries, since
1179 I had no doc available).
1180 (append_selection, append_selection_word): Disable with FIXME
1181 since R4 changed interface here.
1182 (create_buttons): Add back the old set of buttons.
1183 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
1185 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
1186 Roll VERSION to 3.94 (not yet final though).
1188 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1190 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
1191 obstack_int_grow, obstack_int_grow_fast): Eliminate
1192 cast on left of assignment, which gives MIPS cc fits and is
1195 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
1196 F_ALIAS. Use printf, not fprintf, when not passing a file
1198 (compare_opcodes): Check that identical instructions have
1199 identical opcodes, complain otherwise.
1201 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
1202 was reported by Roland McGrath.
1203 (unimp): Only match if exactly zero instruction. (Roland)
1204 (branches and traps): Generate all variations of these
1205 instructions with macros, based on a single call that defines
1206 each condition name and its binary representation.
1207 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
1209 * valprint.c (val_print_fields): Take, and use, format parameter.
1210 This means that "p/x struct" again prints the elements in the
1211 desired format. Changed callers.
1213 * stack.c (frame_info): Use filtered output, and indicate wrap
1214 points. Remove kludgy formatting designed to avoid line wrap.
1216 * utils.c (wrap_here): If the line is already full (because
1217 we had printed a long indent or long wrapped string), do an
1218 immediate newline-and-indent.
1220 * m68k-pinsn.c (print_insn_arg): Bugfix from
1221 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
1222 instruction is incorrectly disassembled as bkpt #8.
1224 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
1225 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
1226 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
1227 and then will dump core (sometimes). I traced it back to an
1228 uninitialized symfile_name in psymtab_to_symtab.
1229 (const_vol_complaint): Add quotes to message.
1230 (define_symbol): Only believe line number if gcc_compiled.
1231 Avoid allocating symbol if we will not return it.
1233 Add target strata support so that newly established targets go
1234 into their right place in the target stack (e.g. a new exec file
1235 doesn't wipe out the ability to access the running process).
1237 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
1238 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
1239 and initialize it properly in all the targets.
1241 * target.h: Document strata. Change return type of push_target.
1243 * target.c (nomemory): new function for dummy memory access.
1244 (tcomplain): Rename complain, now also used in symfile.c.
1245 (push_target): Push targets within strata. New return value shows
1246 whether new target is on top of stack or not. Always keep dummy
1248 (target_files_info): Ignore dummy target.
1250 * core.c (core_open): Warn user, and skip accessing file, if the
1251 core target is not the topmost target in the stack.
1252 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
1255 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
1256 target_ops, it doesn't belong there since we have no regs there.
1257 Change name of target from machine => memory to clarify.
1259 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
1261 * Freeze version 3.93 for release.
1263 * Makefile.dist: Handle vx-share and nindy-share subdirs
1264 properly when building gdb.tar.Z.
1266 * symtab.c: lint; add no_symtab_msg to consolidate the messages
1267 printed in various places, so I could change just one copy.
1269 * dbxread.c, coffread.c: Change references to bfd->iostream
1270 to cast to FILE *, now that BFD avoids needing types defined
1271 in other header files.
1273 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
1275 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
1276 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
1277 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
1278 (actually gcc -Wall).
1280 * dbxread.c: Remove first_global_sym, last_global_sym, since
1281 they are never referenced.
1283 * defs.h (baud_rate): Declare.
1284 main.c: Define it, and add the -b option to set it.
1286 * gdb-int.texinfo: Add text on how to define a new host or target
1287 architecture, prompted by Per Bothner's questions about MIPS
1290 * gdb.texinfo: Document "complaints". Change doc of -q since
1291 gdb no longer prints the copyright and blurb if you specify a file
1292 name to be debugged (just like Emacs). Add doc for Nindy-specific
1293 command line flags for specifying target serial port and such.
1294 Update copyright to 1991.
1296 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
1297 has taken over for us the job of ripping up executable files. The
1298 crud caused Per Bothner's port to not compile.
1300 * infrun.c (normal_stop): Avoid printing "Program exited
1301 normally" if we are in batch mode. This allows a GDB which
1302 executes a program on a target system, to behave like a Unix
1303 command (input from stdin, output to stdout, no extraneous
1306 * main.c (main): Allow additional machine-dependent command line
1307 options to be specified with the ADDITIONAL_OPTIONS,
1308 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
1309 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
1310 processing to occur just before the main loop with
1311 BEFORE_MAIN_LOOP_HOOK.
1312 (main): If a "core file" argument is specified, and it is not a
1313 core file, try it as a process ID to attach.
1314 (symbol_completion_function): Attempt to cope with
1315 "show screen-" TAB, not very successfully. This needs more work,
1317 (batch_file): New function, returns whether we are reading
1318 commands from an interactive tty on stdin, or from somewhere else.
1319 Called by normal_stop since it doesn't get from_tty passed down
1320 to it like many commands do.
1322 * remote-nindy.c: Handle command line options for nindy
1324 (nindy_before_main_loop): Prompt user for tty name if they
1325 don't specify it before getting to the interactive command loop.
1327 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
1328 and -r command line options. Also add hook before main loop
1329 to make it easy to specify a tty.
1331 * TODO: More things to do, one done.
1333 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
1335 * dbxread.c: Make complaint() calls pass pointer, not struct.
1336 Add complaints about badly formatted C++ type information
1337 (const/volatile indicator, and parse errors resulting in
1338 error_type). Fix C++ virtual member fn comment.
1339 (read_struct_type): Avoid bumping pointer if we got a parse
1340 error; this prevents our walking beyond the end of a string.
1341 Terminate loop on null char as well as semicolon.
1342 (process_one_symbol): Fix the LBRAC fix so that it uses the
1343 last previous SLINE, FUN, or SO record's PC address. C++ debug
1344 symbols did not have SLINE records in a useful order compared
1345 to the LBRAC records.
1346 (define_symbol): Handle "catch" records.
1348 * symtab.c (check_stub_type): Added new complain
1349 `stub_noname_complain' and added a consistency check to
1350 keep the debugger from crashing when finishing from an
1351 exception frame. A real fix will be needed later.
1353 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1355 * infcmd.c (attach_command): Make global.
1357 * Makefile.dist (REMOTE_OBS): Make these compile by default,
1358 but make them easy to comment out. Perhaps later they should
1359 be enabled by what CPU you configure for? FIXME.
1360 (VERSION): Roll to 3.93.
1361 (pinsn.o): Remove rule for obsolete file.
1362 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
1364 Run down a problem that manifested by printing the wrong function
1365 name in stack traces of read_ofile_symtab. Turned out that the
1366 problem was the SunOS 4.1.1 (and previous) C compiler outputs
1367 the LBRAC symbol with an address in the *data* segment, which
1368 blew our binary search through the blocks.
1370 * dbxread.c: Use the complain() facility consistently to bitch
1371 about problems in the symbol file we are reading.
1372 (finish_block): Add code to check the nesting of the blocks;
1373 complain and Procrust them to fit if wrong.
1374 (make_blockvector): Check the order of the blocks, complain
1375 [but don't cope] if wrong.
1376 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
1377 symbols to be sure their PC value is greater than the last SLINE
1378 (line number) symbol we've seen, complaining and adopting the
1379 SLINE PC value if wrong.
1381 * symfile.h (struct complaint, complaint_root, complain,
1382 clear_complaints): Add.
1383 * symfile.c (complain, complaint_root, clear_complaints): Add
1384 facility to deal with non-fatal complaints and to regularize their
1386 (symbol_file_add): Clear complaint counters to allow new complaints.
1387 (initialize_symfile): Add 'set complaints' and 'show complaints'.
1389 * dbxread.c (dbx_symfile_read): Remember the address and size
1390 of the string table for the main symbol file, so we won't read it
1392 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
1393 to avoid reading the string table yet again. Lint.
1394 (throughout): Improve filtered output, including word wrap.
1395 (read_range_type): Improve Bothner's fix to handle other types too.
1397 * utils.c: Improve line wrap implementation. Handle unlimited
1398 width by making chars_per_line unsigned.
1399 (puts_filtered): New, easy, function.
1401 * defs.h (puts_filtered): add.
1403 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
1404 call the identical sort_symtab_syms() in symfile.c instead.
1406 * expread.y: Suggest the `file' command rather than `symbol-file'.
1408 * command.h (enum var_types): Add zinteger for seroable
1410 * command.c (do_setshow_command): Handle var_zinteger. Restructure
1411 nested if's into a switch.
1413 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
1414 we did not stop because of a breakpoint (it must have been for
1415 some other reason, like a "stepi"), so don't print anything.
1417 * symtab.c: Include <sys/types.h> all the time. Now that BFD
1418 doesn't include <sys/types.h>, old SunOS's require it for
1421 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
1423 A test port of gdb-3.92.6 to the Sony NEWS.
1426 Don't normally link in remote- or vx stuff.
1427 Some of it doesn't compile, and it wastes space for 99% of the users.
1428 Remove reference to no-longer-used HAVE_VPRINTF.
1429 Fixed BFD_DEP typo to BFD_DIR.
1431 Fix cast in arg to bfd_h_getlong.
1432 Make char *prefix be const.
1433 Fix how certain range types are mapped into builtin unsigned int types.
1435 Remove 2 #includes. They cause errors (on Sony, at least),
1436 and aren't needed (they wern't in earlier versions).
1438 print_address_symbolic should never demangle labels
1439 (since it prints *assembler-level* labels).
1441 [This was superseded by the change to printcmd below.]
1444 Add some "volatile" return types to avoid warnings.
1445 If MISSING_VPRINTF add vprintf function and not just macro
1446 (since vprintf is used in printcmd.c).
1448 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
1449 (The latter isn't grokked by some PCC-based compilers.)
1451 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
1453 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
1454 * nindy-share/coffstrip.c
1455 Added some forward declarations (otherwise, gcc complains
1456 about implicit extern redefined as static).
1458 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
1460 Changes inspired by Per Bothner:
1461 * printcmd.c (print_address_symbolic): Take additional parameter
1462 specifying whether to demangle.
1463 (print_address): Pass in asm_demangle to control demangling.
1464 (print_address_demangle): New fn, takes explicit arg to control
1466 * utils.c: Add new vars demangle and asm_demangle, and let them
1468 (fputs_demangled): If !demangle, just print the argument.
1469 (fprint_symbol): If !demangle, just print raw symbol.
1470 * valprint.c (val_print): Call print_address_demangle rather than
1471 print_address, to cause demangling to depend on the global
1472 rather than assembler-level demangling setting.
1473 * WHATS.NEW, gdb.texinfo: Document.
1475 * main.c (show_command): Show all settings if no arg.
1476 (initialize_main): Make "info set" the same as naked "show".
1477 * command.c (cmd_show_list): Handle prefix commands in the
1478 list, and print the name of the setting as well as its English
1479 description and value.
1481 Allow gdb functions to specify where a line should wrap if it
1482 exceeds the size of a terminal line. Use it to make the output
1484 * utils.c (set_screen_width_command): New fn, mallocs a buffer
1485 of the right size when screen width changes.
1486 (set_screensize_command, screensize_info): Remove #if 0'd fns.
1487 (wrap_here): New fn, indicates a point in the output where we
1488 should wrap the line rather than just letting it overflow at a
1490 (fputs_filtered): Implement wrapping.
1491 (n_spaces): New fn, returns a pointer to N spaces.
1492 (print_spaces_filtered): Use n_spaces.
1493 * defs.h (n_spaces): Declare.
1494 * stack.c (print_frame_info): Wrap with 4-space indent after
1495 fn name and before filename and line number.
1496 * printcmd.c (print_frame_args): Wrap with 4-space indent
1497 before each argument name is printed.
1498 * valprint.c (value_print): Wrap with no indentation before
1500 (val_print_fields): Wrap with indentation relative to nesting
1501 level before each field name.
1502 (val_print): Wrap with nesting indentation before array elements.
1503 * command.c (do_setshow_command): Avoid extra newlines,
1504 wrap with 4-space indent around values printed, end with period.
1505 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
1507 * breakpoint.c (breakpoint_1): Implement addressprint for
1508 "info breakpoints" display. Change file name and line number
1509 format to " at file:nnn" rather than " (file line nnn)".
1510 * gdb.texinfo: Document.
1513 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1515 Frozen for gdb-3.92.6 release.
1517 README, WHATS.NEW: Update for 3.92.6 release.
1519 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
1520 coffread.o from configs since it is now built by default.
1521 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
1522 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
1523 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
1524 from configs since it is now built by default.
1526 Makefile.dist: Update for release 3.92.6. Handle files that
1527 have been moved to ../include, ../getopt, or ../bfd. Add
1528 saber.suppress and tests directory. Add config.status to
1529 the release (it will say "none").
1531 coredep.c: Minor formatting fixes.
1533 These changes were made in early December but only checked in now:
1534 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
1535 nindy-share/nindy.c: lint
1536 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
1537 register values coming back from the target; we store values
1538 in target byte order everywhere.
1540 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
1542 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
1544 * valprint.c (cplus_val_print, val_print_fields): New functions,
1545 which print C++ objects. They conspire to avoid printing a
1546 virtual base class more than once, following all the twists and
1547 turns of C++ virtual base rules.
1548 (val_print): Call the above rather than do it by hand.
1550 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
1551 symbol file, not for added files like shared libs. This really
1552 needs to be generalized to a timestamp per file.
1554 * core.c (cleanup_core): Avoid coredump if no core file.
1556 * config.gdb: Accept -host or -target in place of +host or
1559 * coffread.c (find_linenos): Avoid desupported BFD interface
1560 to line numbers. We still read them manually rather than using
1561 BFD's "generic" features.
1563 * gdbrc.tex, threecol.tex: Add GDB reference card and its
1565 Makefile.dist: Add refcard to OTHERS list for creating tar files.
1567 * Makefile.dist: Eliminate use of $< in explicit targets.
1569 * readline/Makefile: Use $< rather than $*.c, which does not
1570 include the VPATH in GNU Make.
1572 * tconfig/i960-bout, tconfig/i960-coff: These are identical
1573 copies of tconfig/i960, added for global configuration
1574 compatability. All i960 versions can read both coff and b.out.
1576 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
1577 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
1580 * TODO: Think of more things to do.
1582 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
1584 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
1585 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
1586 64-bit float conversion.
1588 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
1589 equivalent to sun?os4 so global config works.
1591 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
1593 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
1595 * main.c: Only declare linesize once; declare pagesize not at
1596 all, since it is never used.
1597 (main): Clear newly allocated line before it is used.
1599 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
1601 Further stabilization for the Intel 960.
1603 * Makefile.dist: Parameterize the location of the "include"
1604 and "bfd" directories, as well as "getopt". Add symfile.c.
1605 Link in both dbxread and coffread. Fix up "make depend" to
1606 rewack the locations of include, bfd, and getopt in its output.
1608 * README: Document moving include files, improve some of
1611 * coffread.c: Move common code out to symfile.c. Change
1612 symbol_file_command style interface to use new *_symfile_init
1613 and *_symfile_read interface under BFD. Use BFD internal
1614 info to locate line table, symbols, etc.
1616 * core.c (core_fetch_registers): Rename to get_core_registers
1617 to avoid confusion with fetch_core_registers.
1618 (register_addr): Move to coredep.c, which is already machine
1619 dependent. This leaves core.c pretty clean of dependencies.
1621 * coredep.c (register_addr): Accept this routine from core.c.
1623 * dbxread.c: Move common code (with coffread.c, etc) into new
1624 symfile.c. Each psymtab now contains a pointer to the
1625 format-dependent function that knows how to read it in. Make
1627 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
1628 (process_one_symbol): Add code to complain about a "compiler bug
1629 we muzzle here", if we actually see it.
1631 * eval.c (evaluate_subexp): Insert missing "break" statements
1632 in code that determines whether a variable is an lvalue in
1633 memory, register, or whatever. I detected this via a compiler
1634 bug in which it *almost* mashed out the whole switch statement.
1636 * gdb-int.texinfo: Add minor sections on configuring gdb for
1637 release, and about the README file.
1639 * infcmd.c (registers_info): Fix formatting somewhat. Still
1640 not as pretty as before, but it handles byte swapping.
1642 * remote-nindy.c: If data cache routines are interrupted while
1643 waiting for the remote end, be sure that any uninitialized cache
1644 blocks are on the free list, not on the valid list!
1646 * symfile.h: Flesh out this header file with all the various
1647 routines and variables that have been merged in from dbxread.c
1648 coffread.c, and symtab.c to symfile.c.
1650 * symfile.c: New file, containing code common to dbxread.c,
1651 coffread.c, and some code from symtab.c. All generic code for
1652 reading symbol files should be in here now.
1653 (unrecord_misc_function): Remove unused function.
1655 * symtab.h: Remove file-reading things to symfile.h.
1657 * symtab.c: Remove file-reading things to symfile.c.
1659 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
1660 to decode i960 fault types.
1662 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
1663 target.c: Change type of the "resume" function from int to void,
1664 since its result was never used.
1666 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
1668 * main.c: Replace "stupid" with "caution"; you now "set caution
1671 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
1673 * infcmd.c (do_registers_info): Call val_print to deal with the
1674 byte order of the registers being printed. FIXME, this makes
1675 the formatting of the output uglier.
1677 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
1678 defined, call it for signals the debugger doesn't itself use.
1679 The i960 uses this for more detailed fault information.
1681 * remote.c (remote_open): If arg is null, print help rather than
1684 * sparc-xdep.c (register_valid): Avoid declaring size, since
1685 various modules will think of various sizes depending on the
1686 architecture of their tm-file. FIXME, we need protection against
1687 actually entering one of those modules, which would clobber
1688 storage if not for the target architecture compiled into gdb.
1690 * stack.c (up_command, down_command): Always print the frame
1692 (up_silently_command, down_silently_command): New commands
1695 * i960-pinsn.c (reg), i960-tdep.c: Lint.
1697 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
1698 more parameters than it used to.
1700 * findvar.c (registers): Increase slop to 256 bytes, which should
1701 protect us against even most RISC machines with large register
1703 (locate_var_value): Move declaration inside related ifdef.
1705 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
1706 throughout, to avoid throwing away buffered input from the board.
1707 (nindy_wait): Supply_register takes addr_of_value, not value.
1708 (i960_print_fault): Renamed from i80960_fault.
1709 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
1710 (nindy_store_registers): Avoid regs_changed stuff, just stuff
1712 (nindy_create_inferior): Don't bother to write PC_REGNUM since
1713 we can set the PC in the call to proceed(). Unpush nindy_ops
1714 before pushing it on top, to avoid message to user. Eliminate
1715 commentary from Unix machines that just misleads here.
1716 (reset_command): Fix error message to suggest target command.
1718 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
1720 Release 3.92.5 as frozen.
1722 Stabilize the merged release...with help from lint, Saber C,
1725 Everywhere: Add include files needed to declare return types
1726 of functions called.
1728 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
1730 * breakpoint.h: Add undeclared breakpoint functions, and some
1731 functions for display handling since I couldn't think of a better
1734 * breakpoint.c (insert_breakpoints): Make code for disabling
1735 shared library bkpts more likely to work. It's used when we
1736 rerun a program and stop before the shared library has been
1738 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
1739 cast from pointer, so it squeezes through catch_errors.
1740 (bpstat_stop_status): Fix logic broken some time ago. We now
1741 always create a bpstat if the stop address matches a breakpoint,
1742 even if we don't stop there -- just like the old code used to do
1743 before I got my fingers into it (sigh).
1744 (breakpoint_1): Print "ignore count" after "stop only if"
1745 condition, since that's how it actually works.
1746 (mention): Handle watchpoints as well as breakpoints.
1747 (watch_command): use set_raw_breakpoint and mention to do most
1748 of the work (and initialize all the fields!). Only pass one
1749 arg to parse_c_expression, since that's all it takes.
1751 * command.c (not_just_help_class_command): Rename arg to args
1752 since we ignore "unused argument" warnings on vars named "args".
1753 inflow.c (child_terminal_info): ditto.
1754 infptrace.c (kill_inferior): ditto
1755 main.c (catch_errors, version_info, quit_command, pwd_command,
1756 source_command, dump_me_command, editing_info,
1757 set_history_size_command, set_history, show_history,
1759 stack.c (locals_info): ditto
1760 target.c (target_files_info): ditto
1761 valprint.c (set_input_radix, set_output_radix): ditto
1763 * core.c: Remove old variables for handling core and exec file
1764 sections (data_start, data_end, stack_start, stack_end,
1765 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
1766 text_end, exec_data_start, exec_data_end, text_offset,
1767 exec_data_offset, data_offset, stack_offset). They're
1768 superseded the more general build_section_table and
1770 (get_exec_file): Mention the `file' command.
1771 (read_memory_check): Rename to memory_error, and only call it
1772 in the case of an actual error.
1773 (read_memory, write_memory): call memory_error.
1774 (core_fetch_registers): Register section name is ".reg".
1776 coredep.c: Remove a bunch of crud now that all this file does
1777 is pull the registers out of a core file.
1778 (fetch_core_registers): Rewrite to actually work, I hope.
1780 dbxread.c: Use a.out.gnu.h, not system a.out, now.
1781 Replace index() with strchr(). Remove all the pre-BFD macro
1782 definitions for accessing the symbol file.
1783 (struct dbx_symfile_info): Encapsulate the information that
1784 dbx_symfile_init needs to pass to dbx_symfile_read in this
1787 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
1788 dbx_symfile_discard): Rearrange symbol file reading to divide
1789 the format-specific part from the format-independent part,
1790 leaving the format-independent part such as file name expansion
1791 and opening in symtab.c. This replaces
1792 partial_symbol_file_open and partial_symbol_file_read.
1793 Symbol_file_read, add_file, add_file_target_command,
1794 add_file_addr_command move to symtab.c. Pass an explicit
1795 "mainline" flag for when reading the main symbol table, rather
1796 than relying on the offset address to be zero or nonzero.
1798 (dbx_symfile_read): Don't allow void *'s to be printed as
1800 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
1801 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
1802 macro" debug version really work.
1803 (read_dbx_symtab): Remove unref'd parameter inclink.
1804 Avoid swapping N_SLINE symbols, for speed.
1805 Merge N_TEXT!N_EXT case with the other external symbol
1806 definitions' case. Add comments.
1807 (start_psymtab): Allocate the symfile name in the psymtab on
1808 the psymbol_obstack, rather than using the caller's storage.
1809 (end_psymtab): Only allocate a dependencies list if there are
1811 (psymtab_to_symtab_2): Use BFD when reopening file to read
1812 its symbols for real.
1813 (read_struct_type): Add FIXME comments where it needs work
1815 (read_huge_number): Add FIXME about overflows.
1816 (read_range_type): Add FIXME about comparing a long to 1<<32.
1818 * coffread.c: Minor changes to move things closer to the new
1819 regime with symtab.c and dbxread.c Major work is still needed
1822 * exec.c (exec_file_command): Remove old variables (see core.c
1824 (xfer_memory): If memory transfer is right at the end of a
1825 section, don't lose.
1827 * findvar.c (get_saved_register): If value is in a real
1828 register, LVAL is lval_register, not lval_memory.
1830 frame.h: Declare print_sel_frame and record_selected_frame.
1832 gdb-int.texinfo: New file, for GDB internals documentation.
1833 Very simple, unformatted doc of cleanups is there for now.
1835 gdbcore.h: Remove obsolete variables that described a.out
1836 section addresses and offsets. (See core.c above.)
1837 Declare fetch_core_registers and registers_fetched.
1839 getopt.c: Declare char *alloca(); even on SPARC.
1841 infcmd.c (run_command): Call target_kill rather than
1843 (step_command, next_command, stepi_command, nexti_command):
1844 Declare from_tty parameter even though we don't use it.
1845 (run_stack_dummy): argument BUFFER is a char array, not
1846 a pointer to REGISTER_TYPE.
1847 (finish_command): using_struct_return needed a value *,
1848 not a struct symbol *.
1850 * infptrace.c (child_xfer_memory): To avoid dependency on
1851 where sections are in memory, try PT_WRITE_D and if that fails,
1852 try PT_WRITE_I. Most Unixes don't care which you use.
1854 * infrun.c (step_resume_break_shadow): Change to array to
1855 match other breakpoint shadow storage.
1856 (clear_proceed_status): Pass address of bpstat to
1857 bpstat_clear, not the bpstat itself.
1858 (child_create_inferior): FIXME comment about if the child
1860 (start_inferior): Remove old function.
1861 (child_open): Use target_kill rather than kill_inferior.
1862 (wait_for_inferior): Ditto.
1863 (insert_step_breakpoint, remote_step_breakpoint): Use
1864 new step_resume_break_shadow.
1866 * inftarg.c (child_wait): If all child processes die,
1867 pretend that the one being waited for exited with signal 42.
1869 * main.c (command_line_input): When scanning for comments,
1870 don't coredump on unclosed quotes.
1871 (quit_command): Use target_kill rther than kill_inferior.
1872 (_initialize_main): Rename class_user from "user" to
1875 * printcmd.c (print_command_1): Initialize "fmt" if no format
1876 is specified by the user.
1877 (print_frame_args): Only add to args_printed if we are
1878 actually fetching args from the stack (avoiding undefined
1880 (_initialize_printcmd): Remove bogus \{ from string.
1882 * remote-eb.c (eb_open): Avoid coredump on no argument.
1884 * remote-nindy.c: Bring out of Intel environment into new
1885 target environment. Remove all conditional compilation on
1886 I80960. Massive hacking throughout.
1887 (nindy_xfer_inferior_memory): New routine stolen from
1889 (nindy_create_inferior): New routine pieced together, probably
1890 not quite working yet.
1891 (nindy_ops): New target_ops struct for nindy.
1893 * remote-vx.c: Use write_memory rather than target_write_memory
1894 to get error checking.
1895 (vx_add_file_command, vx_open): Use symbol_file_add rather than
1897 (vx_create_inferior): Use target_terminal_ours...
1899 * signame.c (_initialize_signame): Always initialize, since
1900 we need the table for things other than psignal.
1902 * solib.c (solib_add): Use symbol_file_add, not add_file.
1903 (solib_address): Return boolean result rather than struct
1904 pointer which nobody else knows the type of.
1906 * sparc-tdep.c, valops.c: Use write_memory rather than
1907 target_write_memory, to get error checking.
1909 * stack.c (locals_info, catch_info, args_info,
1910 get_selected_block, frame_command, up_command): Use
1911 target_has_stack, rather than have_inferior_p or
1914 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
1916 * symfile.h: New file, defining the interface between the
1917 generic and object-file-specific symbol reading code.
1919 * symtab.c: Move generic symbol-reading interface to symtab.c,
1920 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
1921 table to map BFD targets to symbol-reading modules in GDB.
1922 Change index to strchr.
1923 (lookup_struct_elt_type): Use error() rather than hand-made
1924 simulations thereof.
1925 (lookup_partial_symbol): Speedup slightly when length == 0.
1926 (symbol_file_add): New function.
1927 (symbol_file_command): Call it.
1928 (symfile_open, symfile_init): New function.
1929 (add_file_target_command, add_file_addr_command): moved from
1932 * target.c (target_command): use target_kill.
1934 * target.h (target_files_info): Don't declare, never called
1937 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
1938 files to determine stack end address.
1940 * valarith.c (value_x_binop, value_x_unop): Change error message
1941 to be more useful. Pass proper argument to value_struct_elt.
1943 * valops.c (value_assign): FIXME comment that long long
1944 bitfields will break here.
1946 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
1947 Update `make saber_gdb' to work better.
1949 * TODO: A woman's work is never done.
1951 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
1952 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
1953 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
1954 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
1955 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
1956 valops.c, valprint.c, exec.c: Lint.
1959 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
1961 Continuing Intel 960 port merge of GDB.
1963 * Makefile.dist: Merge i960 "nindy-share" files. Rename
1964 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
1965 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
1966 Wack over "make depend" so it handles files in subdirectories
1967 vx-share, nindy-share, bfd, and in the current directory.
1969 * blockframe.c (get_prev_frame_info): Remove fatal error
1970 if stack not defined.
1972 * core.c (core_open, core_detach): New functions that handle
1973 the old "core-file" command as "target core" and "detach" instead.
1974 (core_file_command): Call them.
1975 (core_xfer_memory): Use common routine xfer_memory.
1977 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
1978 dbxread now uses bfd for everything but symbol reading itself.
1979 BFD internals are used to drag out the relevant file offsets.
1980 (partial_symbol_file_open): Change args all around for BFD.
1982 * symtab.c: Rename "value" to "val" everywhere, so we can
1984 (symbol_file_command): New command, moved from dbxread.c
1985 and coffread.c. It uses BFD to read the file, then vectors
1986 based on its type, to dbx or coff symbol readers.
1987 * symtab.h: Extern a few vars for symbol_file_command.
1989 * target.h: Breakpoint takes a char * save area, not a char **.
1991 * valprint.c (val_print): When unpacking bitfields, offset
1992 the address in gdb of the value, if it is declared with a shorter
1993 type. Remove the last "runtime kludge test" of host byte order.
1995 * utils.c: Remove old my_bfd_read routine.
1997 * stack.c (frame_info): Use target_has_stack. Print program counter
1998 register's actual name rather than "pc", since it's called the
1999 "ip" (instruction pointer) on the i960 (sigh).
2001 * target.c (target_command): Add command for selecting a target
2002 type and calling its open routine. This is used for initiating
2003 communication with a particular target, in a generic way.
2005 * tm-i960.h: Update for modern gdb. Remove semicolons from
2006 various macros. Handle reading struct return convention, and
2007 error-out attempts to return structs with the "return" command.
2008 Be sure gdb doesn't think we know how to call functions in the
2011 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
2012 to i960_xxx in lower case.
2013 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
2014 not being defined yet.
2016 * remote.c (remote_open): Call start_remote to initialize
2017 wait_for_inferior during open.
2018 (remote_xfer_inferior_memory): Return length written rather
2021 * remote-vx.c (target_command -> vx_open): Use new generic
2023 * remote-eb.c, inftarg.c, exec.c: ditto.
2025 * infrun.c: Fix comments.
2026 (attach_program -> child_open): Use new generic target command.
2027 (wait_for_inferior): Clear saved register values before target_wait,
2028 so target_wait can set some of them if convenient.
2030 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
2031 Return success indicator, not void.
2032 (child_xfer_memory): Avoid fetching initial word if we'll
2033 overwrite it anyway.
2035 * infcmd.c (attach_command): Use new generic target open routine.
2036 (_initialize_infcmd): Update doc on attach and detach commands.
2037 (do_registers_info): Merge in a byte-order problem as a FIXME
2040 * findvar.c (find_saved_register): Avoid problem in current frame.
2041 (read_relative_register): Ditto.

2053 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
2054 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
2056 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
2058 Merge Intel 960 port of gdb, continuing...
2060 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
2061 symbol_file_command): Pass from_tty arg to hush 'em up.
2063 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
2064 Add magic numbers for 960 COFF format.
2066 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
2068 Merge Intel 960 port of gdb, from Intel "1.2" release.

2087 "-se" switches as soon as they are encountered on the invocation line.
2089 Fri Apr 20 13:47:15 PDT 1990
2092 Thu Apr 19 09:54:28 PDT 1990
2093 Add 'reset' command.
2095 Wed Apr 18 09:48:07 PDT 1990
2096 After opening remote tty, wait for 1 second to go by without input
2097 from it before trying to talk to NINDY (fixes problems with the
2098 Heurikon HK80/V960E).
2100 Mon Apr 4 16:33:05 PDT 1990
2101 Some output was not being suppressed in 'batch' mode.
2103 Thu Mar 22 15:31:11 PST 1990
2104 Ask user if old symbol table should be deleted when new file is
2107 Allow user to run a program downloaded before gdb960 was brought up.
2109 Correct "exec-file" help message for i80960 context.

2134 Mon Oct 2 15:56:31 PDT 1989
2136 Added 960CA disassembly support.
2138 To simplify maintenance:
2139 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c

2142 - moved 960-specific routines from i960-pinsn.c to i960-md.c
2143 - made disassembly interface identical to that in gdmp960.
2147 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
2149 * target.h: Allow targets to stack. Add target_has_memory,
2150 _registers, etc. Restructure memory access and "info files"
2151 to walk the target stack.
2152 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
2153 target.c: Change tables to match target.h.
2154 * inflow.c (child_mourn_inferior): pop child_ops.
2155 (generic_mourn_inferior): Use new has_stack flag.

2157 * inftarg.c (child_files_info): New "info files" regime.
2158 * remote-eb.c: New memory regime, new info files.
2159 * remote-vx.c: New memory regime, new info files. Now use
2160 separate targets for VxWorks attachment to machine, and
2161 actually running a process under VxWorks, since one has
2162 stack & execution & regs and the other doesn't.
2163 * remote.c: New memory regime, new info files.
2164 * sparc-xdep.c (fetch_core-registers): New memory regime.
2165 * target.c: New routines and support for stacked targets,
2166 new memory regime, new info files regime.
2169 Generalize section handling for an arbitrary number of sections,
2170 including use of the new BFD (binary file) library.
2171 * gdbcore.h: Add struct section_table.
2172 * exec.c (build_section_table): Iterate all sections and
2173 record what gdb needs to know about them.
2174 (exec_command): Use it.
2175 (exec_xfer_memory): Use the table.
2176 (exec_files_info): Print the table.
2177 * core.c (core_file_command, core_xfer_memory, core_files_info):
2179 * source.c (find_source_lines): Use bfd_get_mtime.
2180 * dbxread.c: Quick changes to make it compile with new BFD.
2181 * utils.c (error): Avoid using bfd_error in generic routines.
2183 * core.c (core_fetch_registers): Get from the ".regs" section of
2185 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
2187 * inferior.h (attach_flag): Export.
2188 * infcmd.c (run_command): use new target_create_inferior.
2189 * infrun.c (child_create_inferior): Don't return result.
2190 * Makefile.dist (VERSION): 3.91.4.
2192 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
2194 * breakpoint.c (bpstat_num): Handle breakpoints which have
2195 since been deleted, such as temporary breakpoints.
2196 infcmd.c (program_info): ditto.
2198 * core.c (core_file_command): Display the frame where the core
2203 * remote-vx.c (target_command): Merge in target command from
2204 targ-vx.c. A few other cleanups.
2206 * TODO, Projects: Lots more stuff to do...
2208 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
2210 Massive changes to wall off the remote-debugging interface
2211 behind a function vector. The port to handle VxWorks targets
2212 is also part of this.
2214 All files: Replace references to renamed functions,
2215 remove references to remote_debugging, remove references to
2216 have_include_file, have_core_file in favor of target_has_stack,
2217 target_has_memory, etc.
2219 * Modularize the breakpoint interface.
2220 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
2221 a breakpoint instruction.
2222 breakpoint.c: struct breakpoint's shadow_contents now sized as
2224 (insert_breakpoints): Vector to target to install breakpoints.
2225 (remove_breakpoints): Vector to target here too.
2226 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
2227 sparc-tdep.c (single_step): Use new breakpoint interface for
2228 the single-step breakpoints.
2229 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
2230 New file, contains routines to insert and remove breakpoints by
2231 reading out the old contents and later replacing them. This is
2232 how ptrace breakpoints work, and many remote systems as well.
2234 * tm-vxworks68.h: New config file, overrides a few things for
2235 Wind River's preferences.
2237 * target.h: New file, for transfer vector used to talk to the
2238 inferior (child, attached, core, exec, remote, etc). All accesses
2239 to the thing being debugged should come through these vectors.
2240 target.c: New file, routines to handle transfer vector.
2241 (various files): Add transfer vectors XXX_ops for the various
2242 targets and pseudo-targets (core files, etc) we support.
2244 * breakpoint.c (bpstat_stop_status): Further explorations of
2245 watchpoints and why things don't work all the time.
2246 (bpstat_alloc): New fn to allocate a bpstat and chain it.
2248 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
2249 the local gdbinit if it doesn't already have it.
2251 * core.c (core_ops): add and install.
2252 Allow core debugging without exec file.
2254 * dbxread.c (free_and_init_header_files): Merge two fns.
2255 (end_symtab): Free named symbol table when a new version comes in.
2256 (read_dbx_symtab): Relocate all kinds of symbols with base
2257 address. First step toward handling different text, data, bss
2259 (add_file_addr_command): Renamed add_file_command.
2260 (add_file_command): Vector to remote handler.
2261 Add "load" as an alias for "add-file" command.
2263 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
2264 non-returning functions.
2266 * exec.c: Add exec_ops, and push it as a target when an exec
2269 * infcmd.c (run_command): Pass executable file name and arg list
2270 separately when starting an inferior. Permit "run" when no exec
2271 file is specified, for VxWorks.
2272 (detach_command): Move to child_detach in inftarg.c.
2274 * inftarg.c: New file. Unix-child-specific routines, and the
2275 child_ops structure.
2277 * inferior.h (registers): Export "registers" as the way for
2278 target dependent register handlers to find gdb's local copy of
2279 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
2280 since it is now used by places that want wait_for_inferior to
2281 handle the grunge but want to see every trap from the inferior.
2283 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
2284 Eliminate remote_debugging hooks in terminal handling.
2286 * infrun.c: Replace start_inferior with child_create_inferior.
2287 Move all the hair of Unix shells and ptrace idiosyncracies into
2288 child_create_inferior, so remote handlers don't have to deal.
2289 Remove running_in_shell. Rename stop_after_attach to
2290 stop_soon_quietly, and use it in a few other places where we want
2291 to just call wait_for_inferior and get control back on the first
2292 trap. trap_expected now never takes a value > 1.
2293 (init_wait_for_inferior): Initialize static vars when a new
2296 main.c (gdbinit): Add new hook for .gdbinit file name, let
2297 it be overridden by config files as GDBINIT_FILENAME.
2298 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
2299 Both of these are used for VxWorks gdb.
2301 mcheck.c: rename include file "gmalloc.c" to avoid problems
2302 with system include file "malloc.c".
2304 param-no-tm.h: New include file, same as param.h but does not
2305 include the default "tm.h" file. This is used in files where
2306 the target is known, e.g. remote-eb.c or sparc-xdep.c.
2308 param.h: Now just a shell that includes tm.h and param-no-tm.h.
2310 remote-vx.c: New file, VxWorks remote debugging support. Uses
2311 RPC routines that are shared with the target system, in directory
2314 remote.c: Vectorize remote interface.
2316 source.c: Globalize source_path, and make an alias "l" for "list"
2317 since we now have the "load" command.
2319 sparc-xdep.c: Use new param-no-tm.h.
2321 symmisc.c (free_named_symtab): Add new function from Wind River.
2322 However, ifdef it out for now while we think about what it should
2325 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
2327 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
2328 non-Unix-children handle this with their own code in the target
2331 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
2332 source and target lists. Add vx-share to default list of include
2333 directories. Add new files to src and target lists: mem-break,
2334 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
2335 ${srcdir} versions of munch and createtags are used.
2337 * valops.c (find_function_addr): Split out of call_function.
2338 (call_function_by_hand): Rename call_function; this function
2339 calls functions in the target by laboriously patching the target
2340 word-by-word with the right stack, args, regs, etc.
2343 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
2345 Handle AMD 29000 a bit better.
2347 * remote-eb.c (readchar): Mask received char log to make it readable.
2348 (remote_start): Pass arguments down to executing program.
2349 Make startaddr unsigned.
2350 infrun.c (start_inferior): Accept args, pass them to
2352 infcmd.c (run_command): Pass args down to start_inferior.
2354 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
2355 the target object file format.
2356 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
2358 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
2359 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
2361 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
2363 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
2364 * TODO: We did a few things, we have more to do though.
2366 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define.
2367 * inflow.c (inferior_died): Clear deferred stores.
2369 * Debug problems with dummy frames and calls to the inferior.

2372 (sparc_frame_find_saved_regs): Simplify and fix what we find.
2373 (sparc_push_dummy_frame): Simplify and fix what we push.
2374 (sparc_pop_frame): Slightly more hair here, deciding whether
2375 we are restoring a saved PC or returning to a return address in %i7.
2376 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
2378 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
2379 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
2380 * obstack.h (chunkfun): ditto.
2381 * defs.h (xmalloc, xrealloc): ditto
2383 * utils.c (quit): Grab the terminal from the child if necessary.
2385 * inflow.c (term_status_command): Rename to term_info, change
2388 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
2389 (is_delayed_branch): Speed up.
2390 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
2391 Still missing some float ops, and needs testing.
2393 * Support for input and output radixes other than base 10
2394 * defs.h (input_radix, output_radix): Declare.
2395 * expread.y (yyparse, parse_number): Handle changes of input
2396 radix, and ambiguous names-or-numbers in radixes >10.
2397 * printcmd.c (print_scalar_formatted): Print formatted hex
2398 numbers in varying column widths.
2399 * valprint.c (val_print): Use output_format to print scalar ints.
2400 (set_input_radix, set_output_radix, set_radix): Create.
2401 (set_output_radix): Set output_format from output_radix.
2402 (_initialize_valprint): add `set radix' but leave the others off.
2404 * main.c (execute_command): Let stupid questions be turned off.
2405 (_initialize_main): Handle "set stupidity", etc.
2407 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
2408 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
2410 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
2412 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
2413 bfd stuff is still screwed up, but with some manual work, it
2416 * breakpoint.c (bpstat_do_actions): Start over if a command
2417 proceeds the inferior, since the inferior will have stopped and
2418 will need to have its new stop-actions taken care of.
2420 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
2421 compiler fits, simplify it.
2423 * gdb.texinfo (directory command): Doc new dir command.
2424 source.c (directory_command): "dir" now puts things on the front
2425 of the path, moves dups up front, and handles multiple names
2426 on the command line, inserting each one in order. It also
2427 blows away cached line and full_filename info.
2429 * stack.c (backtrace_command): Skip "more stack frames follow"
2432 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
2433 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
2434 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
2435 The only odd one was Gould NP1, which had defined vprintf to
2438 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
2439 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
2440 variable, inspect_it.
2441 valprint.c (print_string, val_print): Use the global inspect_it
2442 to indicate whether to print in Epoch style or normal style.
2444 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
2446 * printcmd.c (call_command): add an alias for the "print" command
2447 which runs expressions and doesn't print the result if void.
2448 (print_command_1): implement it.
2450 * command.c: Remove #if 0'd code. Initialize all the fields
2451 in add_cmd (). Rename do_nothing_command to
2452 not_just_help_class_command, and make it externally visible.
2453 command.h: add user_commands to struct.
2454 * main.c (define_command): Don't overload c->function with a char
2455 string as well as a function pointer.
2457 * eval.c (evaluate_subexp): Reinstall tiemann changes to
2458 calling convention of value_struct_elt () that got dropped in
2461 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
2462 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
2464 * tm-sparc.h (POP_FRAME): replace some constants with defines.
2466 * sparc-xdep.c (store_inferior_registers): defer stores to regs
2467 until a good time (e.g. when we are about to run the child),
2468 saving ptrace calls.
2469 * infrun.c (proceed): handle DO_DEFERRED_STORES.
2470 * tm-sparc.h: define DO_DEFERRED_STORES.
2472 * sparc-xdep.c (store_inferior_registers): when storing float
2473 registers, don't store stack regs too. When storing the SP,
2474 however, DO store the stack regs too. This fixes a bug in which
2475 the dummy frame is not recognized when a call_function finishes,
2476 because its frame pointer (in the stack regs) was never
2478 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
2479 even though we don't know how to read them from an inferior.
2480 valops.c (call_function): Comment about storing SP.
2482 * infrun.c (save_inferior_status): Save away the original bpstat
2483 chain so it can be restored later. Install the copied version for
2484 use by whoever saved the status. It will be blow away by
2485 restore_inferior_status, and the original chain restored. This is
2486 important for people who have pointers into the original.
2488 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
2489 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
2490 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
2493 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
2495 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
2496 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
2497 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
2499 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
2501 * Merge Mike Tiemann's multiple inheritance changes from Sun.
2502 Store the baseclasses in a type struct starting from array element
2503 0 rather than from the unusual array element 1.
2505 dbxread.c: the above.
2506 (virtual_context): Add
2507 Read new debug information about which virtual function table
2508 a virtual function is from, and store it in fn_field.fcontext.
2510 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
2511 TYPE_FN_FIELD_STATIC_P.
2513 symtab.c: the above.
2514 valops.c: the above. Handle pointer casts of object *'s.
2515 (search_struct_method): Add.
2516 (value_struct_elt): First arg is now a pointer to a value, and is
2519 valprint.c: the above.
2520 values.c (value_virtual_fn_field): Add type arg. Handle
2521 offsetting to the proper object when calling virtual fns.
2523 (baseclass_addr): Add valuep arg.
2525 * README: Document the current state of BFD config (missing).
2526 * TODO, ChangeLog, Makefile.dist: Roll version.
2527 * WHATS.NEW: Add summary of changes since 3.5.
2529 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
2531 * dbxread.c (read_struct_type): Clear bit vectors whenever
2533 symtab.c (B_CLRALL): define.
2535 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
2536 using == rather than =. Huh... This fixes the dreaded problem
2537 wherein builtin_type_int becomes TYPE_CODE_FLT.
2539 * core.c (info_files): Show the inferior pid.
2541 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
2542 already knows how to look in the source directory.
2544 * Remove psymtab hair from many places. Remove duplicated code
2545 for searching symbol tables. Hide psymtabs from most places.
2546 Make it fast to get from a psymtab to its symtab.
2548 blockframe.c (blockvector_for_pc): Remove psymtab hair.
2549 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
2550 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
2551 dbxread.c: export psymtab_to_symtab, make it work if called N times.
2552 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
2553 new symtab completely. New psymtabs get symtab pointer
2554 initialized to zero. Remove MI warning printf.
2555 symtab.h: Comments. Add psymtab to symtab pointer.
2556 (PSYMTAB_TO_SYMTAB): New macro.
2557 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
2558 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
2560 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
2562 (print_frame_info): Avoid special-casing symbols that have not yet
2565 * source.c (open_source_file): Quick path if we have already
2566 located the source file by its full name.
2568 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
2569 find_pc_psymtab. When a name is found in the misc function
2570 vector, search the symbol table for its mangled name, not the
2571 name that the user typed.
2573 * bfd.h: Fix missing comment terminators, make #endifs match.
2575 * valarith.c (value_less): Handle unsigned int comparisons.
2576 Add FIXME about pointer compares, which assume host and target
2577 pointers are the same.
2579 * command.c (do_nothing_command): lint
2580 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
2581 fix comments on debug symbol format for visibility. Actually set
2582 visibility of symbols.
2583 main.c (echo_command): lint; use <readline/history.h>.
2584 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
2585 obstack.h (_obstack_blank): Rearrange pointer math to avoid
2586 pointing past end of allocated memory; saber complains.
2587 obstack.h: Declare the external functions that we use.
2588 valarith.h: use <string.h>
2589 solib.c (solib_add): lint.
2591 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
2593 * main.c (initialize_main): Default info_verbose to off, now that
2594 symbol reading is fast.
2595 (quit_command): Avoid clobbering exec_bfd while quitting.
2597 * Initial BFD (binary file diddling library) merger:
2598 coffread.c: Change AOUTHDR to struct exe_hdr.
2600 core.c: initialize initialized data at compile time.
2601 (core_file_command): Move from coredep.c, convert to bfd.
2602 (xfer_core_file): Convert to bfd.
2603 exec.c (exec_file_command): use bfd routines.
2605 mips-tdep.c: Remove exec_file_command and friends.
2608 * coredep.c: (fetch_core_registers) Convert core_file_command to
2609 fetch_core_registers.
2610 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
2612 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
2613 (my_bfd_read): More bogosity, which I don't think we call.
2614 (program_name): Remove this atrocity asap!
2616 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
2619 values.c: allocate_repeat_value was not clearing the
2620 optimized_out field.
2621 (value_static_field): minor stylistic fix (wrong macro was used).
2622 valops.c (value_struct_elt_for_address): didn't work for C++
2625 * signame.c (_initialize_signame): Initialize signal names once.
2627 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
2628 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
2629 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
2631 * remote-eb.c: Support user-settable baud rates on the serial port.
2633 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
2635 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
2637 * tconfig/sun3os4: Remove warning about native assembler,
2638 since it also occurs in the xconfig file.
2640 * findvar.c (registers): Allocate some slop after `registers'
2641 to prevent stray accesses from trashing the next variable.
2643 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
2644 on the sun-3, by changing the #ifdef from `sun3' (which is not
2645 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
2646 vars, which happened to follow `registers' in the executable.
2648 * readline/history.c (history_search): Heed gcc-2's advice
2649 and parenthesize && inside ||).
2651 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
2652 tm-29k.c: Insert FSF copyright headers.
2654 * remote-eb.c: Better comments.
2656 * Makefile.dist: Update to 3.91.6.
2657 * TODO: note PREPARE_TO_STORE problem.
2659 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
2661 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
2663 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
2665 * infrun.c (wait_for_inferior, at end): Don't set up
2666 prev_* if the inferior no longer exists.
2668 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
2669 CANNOT_EXECUTE_STACK.
2670 valops.c (call_function): Use it.
2672 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
2674 * inferior.h (PC_IN_CALL_DUMMY): New macro.
2675 infrun.c (wait_for_inferior, 2 places): Use it.
2677 * values.c (value_being_returned): Only use
2678 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
2680 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
2681 right thing for remote-eb.c.
2683 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
2684 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
2686 * blockframe.c: Put get_frame_saved_regs inside #if !defined
2687 (FRAME_FIND_SAVED_REGS).
2689 * findvar.c ({fetch,store}_registers): Check for
2690 REMOTE_{FETCH_STORE}_REGISTER macro.
2692 * findvar.c (get_saved_register): Add argument lval and
2693 change meaning of argument addr.
2694 findvar.c: Change calls to get_saved_register to reflect
2695 new calling convention.
2696 valops.c (value_assign): Use get_saved_register instead of
2697 find_saved_register.
2699 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
2701 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
2702 an (uninitialized) pointer to one. Use "&" when passing it
2705 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
2707 * coffread.c (getfilename): Use DGUX x_offset and x_name if
2710 * coffread.c (symbol_file_command): Put semicolon after
2712 Put safe_to_init_tdesc_context in #if defined (TDESC).
2713 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
2714 coffread.c: #include <sys/stat.h>.
2715 (read_coff_symtab): Typo: in_source_files -> in_source_file.
2716 Add missing ')' in check for "lc%" and friends. Remove
2718 Declare read_one_sym() at top of file.
2719 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
2720 MC68WRMAGIC can have the same value without causing a duplicate
2723 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
2725 * Allow a Makefile to be built without building the
2726 tm and xm file links that screw up builds in subdirectories.
2727 This is done with `config.gdb none', then you can do things
2728 like `make gdb.tar.Z'.
2729 * tconfig/none: Config file for no target system
2730 * xconfig/none: Config file for no host system
2731 * config.gdb: If no TM or XM files are called out by the
2732 host or target file, don't make links for them.
2734 * cplus-dem.c: Add documentation.
2736 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
2737 simple error, so the user's gdb doesn't crash due to some object
2738 file problem (e.g. somebody is rebuilding the file out from under
2741 * printcmd.c (print_address_symbolic): demangle the symbol.
2743 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
2744 Motorola copyrights in it. Make "make gdb.tar.Z" work.
2745 (alldeps.mak): sort and uniq all results from this; duplicates
2746 hose gdb.tar.Z link building. Remove RCS files from
2747 tconfig and xconfig. Add config files for sun386. Add
2748 a few odd files to OTHERS and HFILES.
2750 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
2752 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
2753 Roll version number to 3.91.5. Make lint work in bindir.
2755 * README: Document cross-debugging and new file structure.
2757 * blockframe.c: Lint. Include "value.h" to declare read_register.
2758 (find_pc_partial_function): remove duplicate line.
2760 * command.h: Lint. Declare error_no_arg and dont_repeat.
2762 * tm-news.h: Remove inadvertently duplicated stuff.
2764 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
2765 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
2767 * config.gdb: Allow `config.gdb host target' form. Clean
2768 up previous change that printed bogus messages when you just said
2771 * core.c: #include "command.h" for lint.
2774 * main.c: Remove some casts of enums. Lint.
2781 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
2783 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
2784 read it from memory. This will allow us to save ptrace calls
2785 eventually. Changed caller single_step too.
2787 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
2788 that we aren't going to use, saving many ptrace calls, especially
2789 when watchpointing or single stepping. Use some #define's for
2791 (store_inferior_registers): Ditto.
2792 (core_file_command): Use some #define's for constants.
2794 * tm-sparc.h: Add #define's for some register numbers, so we
2795 can eliminate the use of random constants in sparc-xdep.c.
2797 * stack.c (frame_command, print_frame_info, up_command,
2798 down_command) Remove frame_changed, since it
2799 causes a bug and doesn't seem to do anything useful. In some
2800 places it was used as a flag, in others as a stack level (?).
2802 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
2803 default is to use the portable (vprintf) version rather than the
2805 * xm-news.h (MISSING_VPRINTF): Add.
2807 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
2809 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
2811 * Remove stuff that forces -Bstatic linking of gdb, and warnings
2812 about linking debugged programs -Bstatic in the sun?os4 config
2813 files in tconfig and xconfig subdirectories.
2815 * main.c (main): Remove unreached exit(0) now that we exit
2818 * Create TODO file for online bug list. There are too many
2819 "little" bugs to keep track of on paper.
2821 * Change Projects file to refer to bug-gdb@cygnus.com
2822 rather than kingdon@ai.
2824 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
2826 * Makefile.dist (VERSION): 3.91.4 now.
2828 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
2829 (condense_misc_bunches): Add sanity check that misc_count is
2830 the same as the number of symbols in the bunch.
2832 * coffread.c: rename init_misc_bunches. Pass an argument
2833 to condense_misc_bunches (a zero).
2835 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
2836 every time we are called; don't rely on our caller to do it.
2837 (add_file): Remove call to init_misc_bunches.
2839 * mipsread.c: Only warn, don't error, if unknown symbol types.
2840 This keeps an old gdb from falling on its face if it sees newly
2841 extended symbol info. Rename init_misc_bunches.
2843 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
2845 * Merge in changes from Per Bothner for DECstations and other
2846 MIPS stuff. The rest is Bothner speaking:
2848 The next message is a merger of Alessando Forin's mips port with
2849 mine. I've tried to use my good if biased judgment to get
2850 the best of both. It *does* need testing.
2852 Some of the changes are general, *not* mips-specific.
2855 Didn't believe in little-endian bit order.
2856 There are still inconsistencies about whether flags
2857 like BITS_BIG_ENDIAN are integer (#if ...) or
2858 boolean (#ifdef ...). I tried to paper over them.
2860 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
2861 Moved some misc_function code that was common to
2862 {dbx,coff,mips}read.c to symtab.c.
2863 In the process, I think I cleaned things up a bit.
2864 At the same time, moved obsavestring and obconcat to symtab.c.
2867 Removed obsolete condense_addl_misc_bunches (use
2868 condense_misc_bunches(1) instead).
2871 Needed to include <sys/dir>, at least on DECstations.
2873 valops.c, mips-tdep.c, tm-mips.h:
2874 Added PUSH_ARGUMENTS macro to support funny argument-pushing
2875 conventions (when STACK_ALIGN is insufficient).
2876 Needed on mips, where doubles need 8-byte alignment,
2877 but ints only need 4.
2880 Removed cruft that was not being used.
2881 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
2884 Print $ before register-names (I think that makes things a little
2886 Never print two instructions, even if one delays.
2887 Removed hex-disassemble set_cmd. (This is not mips-specific,
2888 so I think the argument is whether it is generally worthwhile or not.
2889 I'm inclined to think not, given how easy it is to
2890 convert between radixes in gdb.)
2893 This is basically Alessando's code.
2894 It doesn't use obstacks; I changed it to use obstacks
2895 in a few minor places where using malloc causes a
2896 memory leak. (Probably, more places could/should be changed.)
2897 I added record_misc_function where it was missing.
2898 In symbol_file_command and add_file_command, I tried
2899 to make the code consistent with more recent versions.
2900 Minor sylistic changes in parse_procedure.
2901 Make a .gdbinfo. psuedo-symbol point back to the real
2902 procedure symbol (using the isym field).
2905 This is basically from my port, but with a lot of details
2906 and a number of routines merged in from Alessando's version.
2907 I basically used my code "raw" backtrace (use heuristics
2908 from the actual code, rather than symbol table info) - though
2909 the idea is Alessandro's. I feel my code is a little cleaner
2910 here, particularly in being a little more flexible, such as being
2911 able to handle gcc-produced code (which it now can).
2912 It also doesn't do frame caching (which is not useful
2913 more recent gdb versions).
2914 I also used my code for push_/pop_dummy, more or less.
2915 I tried to incorporate AF's code for testing sigtramp
2916 while backtracing; I probably got it wrong.
2917 Added mips_print_register, which tries to scrunch as much
2918 information as possible on a screen...
2919 Removed the skip-prologue set_cmd. As with hex-disassemble (see
2920 under mips-pinsn.c), I don't see anything mips-specific here,
2921 and I don't see it being all that useful anyway.
2924 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
2925 Use more register names (rather than hard-cases numbers).
2927 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
2929 * Hack up 3.90.11 changes:
2931 * Makefile.dist (depend): parameterize $(GCC).
2932 Add solib.c and solib.o.
2933 (readline): Fix vpath for both absolute or relative SRCDIR.
2935 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
2936 Also, let the part I didn't understand at least compile so
2937 I can test the rest. FIXME.
2939 * dbxread.c: Fix thinko using strcmp.
2940 (init_psymbol_list): declare static.
2941 (partial_symbol_file_open): Comment cleanups better, avoid
2942 cleaning up the string table since the caller will do that.
2943 Move the stat for mod time into symbol_file_command, temporarily.
2944 (There should be a mod time for each symbol file, eventually,
2945 to control its rereading. FIXME.)
2947 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
2948 SunOS, which gives error for shared libs otherwise. (From
2949 Schaefer, probably FIXME needs work for portability.)
2951 * solib.c: Move #include "param.h" to work.
2952 Lowercase all the Uppercase Letters In the Messages.
2953 (find_solib): Clean up inferior_so_name for debug printouts.
2954 Allow no argument, to mean all shared libraries.
2956 * symmisc.c: include param.h to get CLEAR_SOLIB.
2958 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
2960 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9

3001 (record_misc_function): Give correct type for N_DATA symbols.
3002 (condense_misc_bunches): do "misc_function_count = j" regardless
3004 Take code which is shared between symbol_file_command and
3005 add_file_command and put it into partial_symbol_file_{open,read}.
3006 Split add_file_command into add_file_command and add_file.
3007 Make psymtab_to_symtab read in the string table if the file
3009 Two new parameters to read_dbx_symtab and start_psymtab.
3010 tm-sunos.h: New file.
3012 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)

3029 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
3031 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3033 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
3035 * tm-news.h: Add CALL_DUMMY_*.
3037 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
3039 * config.gdb: In list_host, list_target, use ${i}, not $i.
3041 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3043 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
3045 * sparc-opcode.h: Change all store floating-point state register
3046 instructions to have the right match & lose fields.
3048 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3050 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
3052 config.gdb: If srcdir != ., create readline directory and
3053 copy a makefile into it.
3055 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
3056 consistency with POSIX.
3058 * breakpoint.c (bpstat_stop_status): Disable watchpoint
3059 when we exit its exp_valid_block.
3061 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
3063 * Makefile.dist: Bump version to 3.91.3.
3065 * Clean up handling of breakpoint commands (somewhat).
3066 Prompted by Tiemann bug report "cont 10" doesn't work any more.
3068 inferior.h: Add breakpoint_proceeded to inferior status struct
3069 and globals; save it and restore it.
3070 (clear_breakpoint_commands): Cleanup, remove old #define.
3072 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
3073 (save_inferior_status, restore_inferior_status): handle it also.
3074 (proceed): Remove earlier code that set breakpoint_proceeded.
3075 It is now set only in clear_proceed_status.
3076 (clear_proceed_status): Cleanup, use bpstat_clear rather
3077 than clear_breakpoint_commands. No callers need the stop_bpstat
3078 between clear_proceed_status and proceed.
3080 infcmd.c: Add breakpoint_proceeded definition and comment.
3081 (cont_command, jump_command, signal_command): Move call to
3082 clear_proceed_status right next to call to proceed.
3084 breakpoint.c (bpstat_do_actions): Avoid clobbering our
3085 caller's argument while running down the chain of breakpoints.
3086 Use new variable "breakpoint_proceeded" to determine when
3087 a command that it executes moves the inferior past the
3089 (bpstat_clear): Handle NULL argument.
3090 (bpstat_clear_actions): Avoid useless call to
3091 breakpoint_auto_delete.
3092 (delete_breakpoint): Clean up bpstat's that are pointing to
3093 the deleted breakpoint from the stop_bpstat chain.
3094 (breakpoint_auto_delete): Simplify.
3096 * Clean up handling of EOF, error on stdin, etc. This was
3097 prompted by a network problem that caused gdb to go into an
3098 infinite loop filling up its malloc'd memory.
3100 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
3101 not clear_breakpoints_commands, which is now gone.
3102 (main): If command_loop returns (e.g. from EOF on stdin), do
3103 a quit_command (looping back to command_loop if quit_command
3104 doesn't really quit).
3105 (command_loop): check result from command_line_input and
3106 exit if it returns NULL, rather than passing the NULL to
3108 (gdb_readline): Free malloc'd result space before returning
3111 * utils.c (query): Handle C-d to mean "yes", just as if the
3112 input was not a terminal. Also avoid infinite loop if EOF
3113 occurs in mid-input-line before newline. This allows
3114 query to be used at EOF on stdin with reasonable results.
3116 * infrun.c (proceed): Set breakpoint_proceeded.
3118 * values.c (value_as_long): Avoid infinite recursion for enums.
3119 (_initialize_values): Fix typo in help msg (kingdon).
3121 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
3122 RL_LIB for linking. This allows -lreadline for linking
3123 and nothing for dependencies, once readline is a real library.
3125 * config.gdb: Jim Kingdon: give useful error message if the
3126 host or target type is not recognized.
3128 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
3129 it just defines it. Dumb, but deal with it.
3131 * Jim Kingdon suggests:
3132 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
3134 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
3136 * Makefile.dist (VERSION): Bump version # to 3.91.2.
3138 * Clean up Bothner's changes.
3140 * blockframe.c (clear_pc_function_cache): New function.
3141 * blockframe.c: remake cache_pc_function_* static.
3142 * dbxread.c (symbol_file_command): remove references to
3143 cache_pc_function_* variables.
3144 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
3145 * printcmd.c: Avoid kludging a global variable (addressprint)
3146 to avoid printing the address of a string twice. Instead,
3147 pass the format letter 's' down low enough that it can be seen
3148 to avoid this problem.
3149 (print_formatted): Pass format arg to value_print.
3150 (restore_addressprint): Remove function.
3151 (do_examine): Avoid hacking addressprint, cleanups and such.
3152 (print_frame_args): Add a comment to a Bothner change.
3153 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
3154 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
3155 to wipe out the values cached in blockframe.c.
3156 * symtab.c (find_method): Add comment saying how big you must
3157 allocate to be "big enough". Per being terse again.
3158 * valprint.c (val_print): Handle format letter "s" to print
3159 strings without addresses. Add comment to vtbl printing code
3160 which casts with wild abandon. Rearrange reference-printing
3162 @0xaddr: value (print w/addressprint)
3163 value (print w/~addressprint)
3164 @0xaddr (parameter lists w/addressprint)
3165 or nothing (parameter lists w/o addressprint)
3167 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
3169 * Merge more changes from Per Bothner:
3171 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
3172 annoying) that I tried to improve it. Here are my suggestions.
3174 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
3177 Do automatic de-reference when taking the address of a reference.
3179 Don't deref_ref when printing parameter lists.
3181 More attempts at treating refernences properly.
3183 In val_print, if deref_ref==0, don't print dangling " = ".
3185 Add COERCE_REF macro, which de-references an REF.
3187 * Merge changes from Per Bothner:
3189 * Fixed (Sony news)-specific configuration problems.
3190 * Fixed other problems with using vanilla pcc and libc (enum problems;
3191 assumption that vsprintf exists).
3192 * Some major speed-ups (finc_pc_partial_function now caches a match;
3193 parsing avoids duplicate symbol_lookup calls).
3194 * Changed handling of baseclasses (no longer use baseclasses field
3195 of struct type, use the first n_baseclasses fields instead).
3196 * Various minor changes/fixes, most C++-related.
3199 Cache the most previous match from find_pc_partial_function.
3200 (Save both low and high ends of matching function's pc range.)
3201 This speeds up the loop of infrun.c:wait_for_inferior quite
3202 a bit, and makes step/next commands much zippier.
3204 Added an enum->int cast (otherwise, some compilers barf).
3206 No longer set baseclass offset to 0, since multiple
3207 inheritance now mostly works.
3208 Added a number of casts, to shut up compiler warnings
3209 (after stabs where made enums, not ints).
3210 When discarding a symbol table (in symbol_file_command),
3211 must clear the cache introduced in blockframe.c.
3212 Don't convert $vtbl_ptr_type to vtbl any more.
3213 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
3214 Mask off sign bit emitted by g++ for virtual table offset.
3215 Set voffset to -1 (not 1) for static member functions.
3217 Changed parsing/lexing of names to avoid doing symbol lookup twice
3218 (once when lexing to determine symbol class, once for real).
3219 Now only call symbol_lookup once. Fields of 'this' win especially big.
3221 Subpress printing addr twice in the case of 'x/s addr'.
3223 lookup_basetype_type is no longer used.
3224 Add find_methods as recursive helper function to decode_line_1.
3225 This allows multiple inheritance to work.
3226 Also, once one or more matches has been found, do not look in
3227 base-classes. (Baseclass methods would be overridden, anyway.)
3229 Removed baseclasses array in struct type.
3230 Instead of using baseclasses[i], use fields[i-1].
3231 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
3232 Changed sign convention of voffset (previous was inconsistent).
3234 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
3236 Used to assume existence of vsprintf. Re-written to not need it
3237 if HAVE_VPRINTF is undefined.
3239 typecmp was too pessimistic. Made it less so.
3241 Don't print space after address.
3242 If vtable points to a misc symbol (with 0 offset), print it,
3243 since that indicates the actual class of the object.
3244 Changed ype_print_derivation_info to use new inheritance
3245 scheme (without baseclasses vector).
3247 In value_primitive_field, fixed some bugs left over from previous set of fixes.
3248 Also, changes needed because TYPE_BASECLASSES were removed.
3250 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
3252 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
3255 If there is no path set, and the symbols don't indicate what directory
3256 a file was compiled in, look in the current directory. But either
3257 a path or a known compilation directory will prevent this.
3260 Three independent bug fixes:
3261 * Remove the #if 0 block that breaks some stuff.
3262 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
3263 adapt gdb to either SunOS 4.0.* or 4.1.
3264 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
3267 Instantiate the class T when looking for methods in it. (Tiemann@sun)
3270 (type_print) Demangle the name being printed.
3271 (type_print_base) Handle botched demangling without coredump (tiemann).
3274 (check_stub_method): Document routine.
3275 (tiemann) fix bug for no-arg functions
3276 Avoid clobbering beyond end of malloc'd storage.
3277 Terminate the argument list properly.
3279 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
3281 * Changes merged by John Gilmore:
3284 In breakpoint_1, use new print_address_symbolic instead
3285 of find_pc_partial_function. (This forces use of assembler-level
3286 addresses, and avoids misleading non-mangled source-level names.)
3288 Generalize ansi argument such that -1 means skip arglist totally.
3289 Removed global variable print_ansi_qualifiers (which made
3290 code non-reentrant), in favor of extra explicit arguments
3291 to internal routines.
3293 Add new helper function print_address_symbolic.
3294 Use find_pc_misc_function instead of find_pc_partial_function
3295 (since we want assembler-level symbols here).
3297 Print unknown function as just "f (...)", not "f (...) (...)".
3298 Use new fputs_demangled explicitly.
3300 Fixed a typing violation (problem: value.h cannot be imported
3301 without renaming many variable in this file).
3302 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
3303 decode_line_1: Moved forward some never-reached code.
3304 Made decode_line_2 skip function prologues correctly.
3306 fputs_filtered should not demangle by default.
3307 Add new fputs_demangled to demangle on demand..
3309 Change value_struct_elt to use value_primitive_field (using recursive
3310 utility function search_struct_field). This allows foo.bar to work
3311 for multiple inheritance (so far only for data fields).
3312 Change check_field in the same way (recursive helper function
3313 to support multiple inheritance).
3314 (Note: there are more of these problems that I haven't fixed.
3315 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
3316 value_of_this: 'this' symbol name is now just "this", note "$this".
3318 Don't print static members.
3319 Avoid printing "members of <type>" if there are none.
3320 Simplified type_print_derivation_info by merging duplicate code.
3321 Remove useless blank lines in type_print_base (ptype command).
3323 Added declaration of new routine value_primitive_field.
3325 Added value_primitive_field which is generalized version of
3326 value_field that can handle multiple inheritance (non-zero offsets etc).
3327 Re-implemented value_field to call value_primitive_field.
3329 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
3331 * infcmd.c -- insert else to avoid 'delete env' coredump when you
3332 delete the whole environment. Karl Berry reported the bug.
3333 * source.c - fix openp to avoid //'s in filenames, which
3334 trigger an Emacs bug causing it to not be able to find files
3335 when running gdb in a window.
3336 * dbxread.c - zap the #if 0 that botches the add-file code.
3337 It seems to work a lot better without all the code commented out.
3339 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
3341 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
3344 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
3346 * Makefile - added a ${CFLAGS} to a couple of entries,
3347 added remote-sa.sparc.c
3348 * added remote.sa-sparc.c, a modification of remote.c
3349 which conducts a dialog directly with the SparcStation prom.
3350 * breakpoint.c, infrun.c, sparcdep.c added
3351 remote_insert_breakpoint(), and remote_remove_breakpoint()
3352 to breakpoint.c instead of directly writing breakpoint instructions.
3353 * sparcdep.c on remote_debugging,there is no need
3354 to remove signle step breakpoint instructions.
3355 * main.c added "-epoch" flag and "int epoch_interface" to main.c
3357 * printcmd.c - epoch interface sends lisp expressions to open up
3358 epoch windows on inspection.
3359 * valprint.c - added arrayprint, and addressprint and made adding
3360 format controls easier
3361 * wait.h added a couple of undef's because we were getting
3362 complaints about WSTOPSIG and WTERMSIG begin redefined.
3365 Wed Jul 4 05:27:51 1990 Michael Tiemann (tiemann at masham)
3367 * symtab.c (decode_line_1): Add support for handling method stubs
3368 in the type information.
3370 Tue Jul 3 09:39:18 1990 Michael Tiemann (tiemann at masham)
3372 * values.c (baseclass_addr): Run loop from INDEX+1 to
3373 N_BASECLASSES; otherwise, we can still get into a loop.
3374 @@ This should be restructured to use a cleaner search strategy.
3376 Sun Jul 1 12:28:51 1990 Michael Tiemann (tiemann at masham)
3378 * dbxread.c (define_symbol,read_type): Grok GNU C++'s new
3379 abbreviation "Tt" for tags which have the same name as their
3382 Fri Jun 29 01:03:46 1990 Michael Tiemann (tiemann at masham)
3384 * symtab.c (list_symbols): add ability to set breakpoints on all
3385 the functions which match a particular regular expression.
3387 Tue Jun 26 04:26:29 1990 Michael Tiemann (tiemann at masham)
3389 * cplus-dem.c (cplus_demangle): New parameter ANSI says whether we
3390 should print ANSI qualifiers (such as `const' and `volatile').
3391 All callers changed to call with ANSI == 1, except from
3392 `check_method_stub', which uses old-style syntax.
3394 * symseg.h (struct fn_field): Remove unneccessary `args' field.
3395 * symtab.h (TYPE_FN_FIELD_ARGS): Redefined.
3397 * values.c (check_stub_method): New function.
3399 * cplus-dem.c (do_type): Handle "long long" (encoded as 'x').
3401 * dbxread.c (read_type): Handle new GNU C++ method type stubs.
3402 * valprint (type_print_base): Ditto.
3404 * symtab.c (gdb_mangle_typename): New function.
3406 Tue Jun 5 00:18:43 1990 Michael Tiemann (tiemann at gzilla)
3408 * breakpoint.c (catch_command): New function. Provides a
3409 mechanism to set breakpoints based on catch clauses.
3410 (disable_catch): Similar, but disables breakpoints on catch
3412 (delete_catch): Similar, but deleted breakpoints on catch clauses.
3414 Sun Jun 3 22:54:08 1990 Michael Tiemann (tiemann at gzilla)
3416 * blockframe.c (blockvector_for_pc): New function.
3417 * blockframe.c (block_for_pc): Changed to call
3418 `blockvector_for_pc' and get the block itself.
3420 * stack.c (catch_info): New function. Prints info about
3421 exceptions which can be caught in the current frame.
3422 * stack.c (print_frame_label_vars): New function. Similar to
3423 `print_frame_local_vars'.
3424 * stack.c (print_block_frame_labels): Prints out labels that are
3425 defined in this frame. These labels are exceptions that can be
3428 * dbxread.c: Updated to handle N_CATCH symtab types.
3430 Thu May 3 22:10:00 1990 Michael Tiemann (tiemann at teacake)
3432 * valprint.c (everywhere): TYPE_NAME (TYPE) no longer comes in the
3433 form "struct ..." for GNU C++. Don't flush any part of TYPE_NAME
3434 when printing the type.
3436 Wed May 2 22:43:04 1990 Michael Tiemann (tiemann at teacake)
3438 * valprint.c (val_print): Use `baseclass_addr' to access the
3439 baseclasses pointed to via the derived class object at VALADDR.
3441 * values.c (baseclass_addr): New function. Casts derived pointers
3442 to baseclass pointers taking virtual baseclasses and multiple
3443 inheritance into account.
3445 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3449 Fri May 4 12:12:55 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3451 * breakpoint.c (watch_command, bpstat_stop_status): Deal with
3452 exp_valid_block field correctly.
3454 * infrun.c (wait_for_inferior): When checking "don't even think
3455 about breakpoints" if stop_signal == SIGTRAP && trap_expected,
3456 also check step_resume_breakpoint.
3457 Insert breakpoints and continue (not step) if
3458 step_resume_break_address != NULL, even if another_trap.
3459 If trap_expected and we enter sigtramp, then set up a
3461 If trap_expected is set when we hit the step_resume_break,
3463 When calling resume and trap_expected says tell resume to step
3464 (2 places), also check step_resume_break_address.
3466 * infrun.c (wait_for_inferior): Don't set
3467 prev_{pc,sp,func_{start,name}} before calling wait ().
3468 Do set them after exiting loop.
3469 Move their declarations outside functions.
3470 (start_inferior): Initialize them.
3472 Thu May 3 00:15:11 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3474 * infrun.c (wait_for_inferior, after check for trap_expected > 1):
3475 Restore old code which distinguishes between trap_expected and
3476 running_in_shell, just make the latter take any non-TRAP signal,
3479 * values.c (allocate_value): Zero VALUE_OPTIMIZED_OUT flag.
3481 * Makefile.dist (pinsn.o): Use PINSN_CC to compile.
3482 xconfig/3b1 (CC,PINSN_CC): Define.

3501 (printf_command): Add from_tty parameter.
3503 * valprint.c (value_print): Check VALUE_OPTIMIZED_OUT flag.
3505 * value.h: Add optimized_out field and change lazy field to
3506 char. Add macro VALUE_OPTIMIZED_OUT.
3508 * i386-pinsn.c: Change from Eirik Fuller to write to stream directly
3509 instead of stuffing things in buffers (oappend, etc).
3511 * breakpoint.c (bpstat_do_actions): If *BSP is set to NULL by
3512 execute_command, exit both loops.
3514 * Makefile.dist: Don't set TARGET_ARCH. Add .c.o rule.
3516 Tue May 1 17:07:23 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3518 * Makefile.dist (RAPP_OBS, rapp),
3519 rgdb.c, rserial.c, rudp.c, serial.c, udp.c, xdep.h,
3521 m68k-xdep.c, coredep.c: Wrap in #if !defined (RDB).
3523 * valops.c (value_struct_elt), values.c (value_static_field):
3524 Change error messages to remove references to `info methods'.
3526 Tue Apr 24 10:25:10 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3529 infrun.c (start_inferior): Add START_INFERIOR_HOOK.
3530 infcmd.c [SHIFT_INST_REGS]: New code.
3531 findvar.c (read_relative_register_raw_bytes): Return a value.
3532 infcmd.c (do_registers_info): Check value from
3533 read_relative_register_raw_bytes.
3535 * command.c (delete_cmd): Free the struct cmd_list_element(s)
3538 Mon Apr 23 10:42:21 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3541 findvar.c (get_saved_register): New function.
3542 findvar.c: Rewrite code which called find_saved_register to
3543 call get_saved_register instead.
3545 Sun Apr 22 14:47:51 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3547 * valprint.c (val_print): Change error message printed when
3548 the type has TYPE_FLAG_STUB set.

3561 (store_inferior_registers): Don't call read_register_bytes.
3562 symmetry-xdep.c (store_inferior_registers):
3563 #if 0 out code to fetch registers.
3565 * values.c (value_as_long): Call COERCE_ARRAY.
3567 * tm-sun3.h: Include tm-68k.h not m-68k.h
