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

277 queued to the psymtab list.
279 * symfile.c (symbol_file_add): Use filtered printing and wrap it.
280 If we have wiped out any old symbol tables, clean up at end of

284 * symtab.h (GLOBAL_BLOCK, STATIC_BLOCK, FIRST_LOCAL_BLOCK): New
285 defines for the blocks of a blockvector that contain global and
286 file-static symbols and the first of the smaller scope contours.
287 * symtab.c (lookup_symbol, find_pc_symtab, find_pc_line,

335 queued to the psymtab list.

338 If we have wiped out any old symbol tables, clean up at end of

380 (set_section_command): New command ("section xxx yyy" -- should
381 be renamed to "set section xxx yyy" FIXME) which sets the
382 base address of a section of the exec file, overriding the
383 virtual address that BFD reports.
385 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
387 * exec.c: Add add_syms_addr_command to exec_ops, so you can

390 Thu Apr 4 10:09:35 1991 John Gilmore (gnu at cygint.cygnus.com)
392 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code

395 * i386-pinsn.c: Move #includes to top, remove useless ones.
396 * i386-tdep.c: Don't bother including <.../reg.h> since we

401 (ieee_test): Make numbers really random; fix format arg.
403 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
404 * core.c (core_detach): Unpush core_ops, which might not be on
405 top. We used to just pop the top, which broke things. Don't

408 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.

410 BINOP_ASSIGN_MODIFY, so we can print += and such.
412 * inflow.c (kill_command): After killing inferior, print our
413 current frame in the core file, if we have one.
414 (generic_mourn_inferior): When inferior dies, either select
415 the current frame (in the new target, e.g. core file), or
416 set both the current and selected frames to NULL.
418 Changes from Peter Schauer.
420 * infptrace.c: Avoid <sys/ptrace.h> on USG.
422 * Make all file names fit in 14 characters (sigh and damn!):
423 mv hp300hpux-xdep.c hp300ux-xdep.c
424 mv symmetry-xdep.c symm-xdep.c
425 mv symmetry-tdep.c symm-tdep.c
426 mv convex-opcode.h convx-opcode.h
427 mv tm-vxworks960.h tm-vx960.h
428 mv tm-vxworks68.h tm-vx68.h
429 mv Makefile.srcdir Makefile.sdir
430 mv gdb-int.texinfo gdbint.texinfo
431 mv remote-sa.m68k.shar rem-m68k.shar
432 mv remote-multi.shar rem-multi.shar
433 * Makefile.dist, README, config.gdb, convex-pinsn.c,
434 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
435 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter

441 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
443 * dbxread.c (really_free_pendings): Clear file_symbols
444 and global_symbols after freeing them; otherwise, running
445 this function twice (if it appears twice on the cleanup
446 chain), we try to free things twice.
448 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
449 based on text_addr (the address of text in core), not on addr (the
450 offset between text in the .o file and in core). This change
451 is from Peter Schauer.
453 * main.c: Define ALL_CLEANUPS as a cast of zero.
454 (return_to_top_level): Use it.
455 (main): Do all cleanups after each command run as part
456 of the gdb startup sequence. Also do all cleanups before
457 entering the command loop, and every time we exit the command
458 loop and reenter. Before, the cleanups from the startup sequence
459 were being left undone until the first error!
460 (command_loop): Rename do_nothing cleanup to command_loop_marker
461 so we can see it easily when examining the cleanup chain.
462 (init_signals): Add another do_nothing for signal handling.
463 (quit_command): Only try to kill target if it has execution.
464 Problems in the target stack got us into a state where
465 inferior_pid was nonzero but none of the targets had execution.
466 In this state you couldn't exit gdb.
468 * dbxread.c: Two changes from Peter Schauer.
469 (echo_command): Fflush output after an echo command.
470 (show_history): Pass all args to cmd_show_list.
472 * utils.c (init_malloc): Call mtrace to turn on tracing
473 if the environment variable MALLOC_TRACE is set to a file name.
474 * mtrace.c: Add source file which provides a log of every malloc,
475 free, and realloc to a trace file.
476 * mtrace.awk: Add source file which analyzes the trace file.
477 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
478 (VERSION): Roll to 3.94.3.
480 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
481 (check_duplicates): Don't bother with watchpoints.
482 (set_raw_breakpoint): Comment about danger of this routine.
483 (watch_command): Parse and eval all args before calling
486 * solib.c (find_solib): Avoid error in referencing memory to
487 see if any more shared libraries have been added. This is
488 particularly useful if the target has terminated. Bug reported
492 in bringing up 3.94.2 on the Sun-3.
494 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
495 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
496 expression (in scope) before reenabling watchpoint.
497 * signame.c (init_sigs): Add missing declaration of i, fix
498 sys_siglist declaration.
499 * source.c (list_command): Fixed range computation to use
501 * stack.c (backtrace_command): Do not allow command if target has
502 no stack, print informative error message.
503 * target.c (target_command): Do not write into command line
504 because this fails if the target command is used in a user defined
505 command. [This change was enhanced by gnu to support any-
506 unique-prefix matching on target names.]
507 * valops.c (value_struct_elt): Avoid infinite loop on an
508 erroneous attempt to print the member of function (try p main.p).
510 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
512 * expread.y (name_no_typename): Avoid reduce/reduce errors
513 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
514 Since the GDB parser really doesn't use name_no_typename in a
515 name-only context, the parser can't tell the diff between
516 names and numbers here. Avoid allowing a name_no_typename
517 to be a NAME_OR_*INT to resolve the conflict.
519 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
523 * valprint.c (val_print_fields): bitfield printing didn't handle
524 byte order. Indirect through a few more fns to cope.
526 * values.c (modify_field): also cope with byte order.
528 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
530 Cleanup for release 3.94.2:
532 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
533 include files. Roll version to 3.94.2.
535 * coffread.c (init_stringtab): Read length into unsigned char
536 array before swapping; don't assume 32-bit longs.
538 * target.c (target_info): Don't bother with get_sym_file, just use
539 the symfile global variable.
540 * symtab.h, symfile.c (get_sym_file): Delete it.
542 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
543 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
544 (read_type): Replace one more error() with complain().
546 * mipsread.c (parse_partial_symbols): Replace printf with complain.
548 * i960-tdep.c: Fix copyright attribution.
550 * config.gdb: Quote all backquotes in doublequotes. You can
551 quote me on that. BSD 4.4 shell found this one.
553 * infptrace.c (throughout): The third argument to ptrace is an
556 * infrun.c (wait_for_inferior): When program has terminated, we
557 have to call target_terminal_ours before we pop that target off
558 the stack (e.g. before a call to target_kill or
559 target_mourn_inferior). This fixes problem where a program
560 terminates, then GDB stops for (tty output) and you have to type
561 "fg" to the shell to resume it. FIXME: This code for what to
562 do after termination really should be in normal_stop instead.
564 * gdbcore.h (read_memory_check): Change declaration; it changed
567 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
568 4.4 prereleases, this avoids a bug in their sgtty compatability
570 * remote.c: Use terminal.h rather than hand-rolling the same.
572 * signame.c, signame.h (psignal): Arg is unsigned, not int.
573 * utils.c (strsave, strstr): Fix arg types.
574 * valprint.c (val_print): lint
576 MIPS symbol table support from Per Bothner:
578 * symfile.c (symtab_fns): Remove initializer table that needs to
579 be hacked for each new symbol file format supported.
580 (add_symtab_fns): New function, chains symbol table
581 handlers into the global list.
582 (symfile_init): Search this list.
583 * symfile.h: Add next pointer, declare add_symtab_fns.
584 * coffread.c (_initialize_coffread): Call add_symtab_fns.
585 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
587 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
588 symbol *). Thus, we no longer need the hack to trash
589 pst->filename. Good, since that hack confused code in symfile.c!
591 (reorder_symtabs, destroy_all_symtabs): Removed static
592 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
593 Instead, the latter now uses a temporary array (stack-allocated
594 from an obstack, and then freed).
596 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
597 haven't been set in the outermost stBlock of a procedure. This was
598 a problem with f77 binaries on Ultrix 4.?.
600 (new_symtab, new_symbol, new_type): Continue changing code to use
601 obstacks more and otherwise conform to dbxread internal style.
602 Made the free_code of symtabs be free_linetable (as in dbxread)
603 instead of free_contents. This implies memory leaks when reading
604 a new symbol table, until the conversion is finished. Did change
605 (struct symbol) and (struct type) to be allocated on the
606 symbol_obstack. Blocks and blockvectors are among the things
609 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
610 tested much, but it solved one problem (reported by Meissner), and
611 cleans up some other things. The problem happened when an
612 included file contains actual code (functions) and not just
613 definitions. The mips coff is a little inconvenient there, since
614 it may cause a procedure to be mapped to the wrong psymtab.
616 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
617 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
618 this will need work for the new core paradigm.
620 Opcode patches from the net:
622 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
623 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
624 missing altogether - they are added here. From Bruce Bauman.
625 * mips-opcode.h: The low mask for C0 instructions was too small.
626 From Garrett Lau. I modified the fix to check the entire 32-bit
629 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
632 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
634 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
636 * dbxread.c (read_type): Pointer subtraction (value_sub in
637 valarith.c) sometimes failed because the types of the
638 pointers being subtracted were not identical.
639 These differed because dbxread.c was allocating pointer types
640 using dbx_alloc_type+smash_to_pointer_type instead of
641 lookup_pointer_type. I failed to find a justification for the
642 former, so I changed it to use the latter. Similarly, I
643 replaced smash_to_function_type by lookup_function_type,
644 and smash_to_reference_type by lookup_reference_type.
646 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
647 _initialize_mipsread): corresponding changes.
649 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
651 * source.c (mod_path): Do tilde_expand on each component of the path,
652 rather than on the (list of) paths as a whole.
653 (print_source_lines): Set first_line_listed in addition to
654 current_source_symtab and current_source_line. If the source was
655 not findable, after a "dir" command to fix the problem,
656 a "list" would get the wrong lines.
658 While I was there... (gnu):
660 * dbxread.c (read_type): Change error to complaint.
662 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
664 First attempt at detailed understanding of symbol table memory alloc.
666 * dbxread.c (dbx_symfile_read): Free our string table if we
667 aren't the mainline. Free the "info" struct since we're done with
669 (init_psymbol_list): Free any previously allocated psymbol lists.
670 (): FIXME: Should realloc-down the psymbol lists when done reading
671 the main symbol file?
673 * symmisc.c (free_symtab): Free fullname field too.
675 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
676 (REGISTER_ADDR): Make result type unsigned int.
678 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
679 define REGEX must also define REGEX1 (its dependency).
681 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
683 * tconfig/i960: No longer works, points you at vxworks960 or
686 * xgdb.c, XGDB-README: Remove file. Users can get the much
688 * Makefile.dist: Remove all trace of xgdb.
690 * breakpoint.c (breakpoint_1): Pass demangle arg to
691 print_address_symbolic.
692 (clear_breakpoints): Remove unused function.
693 (breakpoint_re_set_one): Guts of breakpoint_re_set.
694 (breakpoint_re_set): Use catch_errors to do them all anyway.
696 * gdb-int.texinfo (Host versus Target): Add section on what is
697 a "host" feature versus what is a "target" feature.
699 * infcmd.c (path_command, path_info): Handle the PATH variable
700 (object search path) as conveniently as the source search path.
701 * environ.c (set_in_environ): Set some vars in GDB's environment,
702 in addition to the child's. PATH, G960BASE, G960BIN for starters.
703 * source.c (mod_path): New function, from guts of
704 directory_command, modifies a path. Used by path_command.
705 (directory_command): Call it.
706 * defs.h (strsave): Declare.
708 * utils.c (sevenbit_strings): Add new printing option.
710 (strsave): Provide this handy helper routine.
711 (set_width_command): Rename set_screen_width_command.
712 (_initialize_utils): "set screen-width" => "set width";
713 "set screen-height" => "set height"; add sevenbit-strings.
715 * infcmd.c (do_registers_info): Print floating point registers
716 in raw hex as well as float format, regardless of whether it is
717 a "virtual" convertible register.
718 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
719 regs as a double, just in case it's being used that way.
720 * values.c (unpack_long): Comment on array/function coercion.
721 (unpack_double): Argument is in target byte order now. For
722 integer arguments, just call unpack_long and float the result.
723 * m68k-tdep.c: include defs.h for "const" handling.
724 * remote-nindy.c: Use ieee-float stuff.
725 (nindy_fetch_registers): Unpack double regs to host double, then
727 (nindy_store_registers): Pack extendeds to host double, flip
728 around by misusing unpack_double, send as target double.
730 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
731 zero, as when stopped at the first instruction of a process.
733 * blockframe.c: Fix filename in comment (param.h => tm.h).
734 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
735 * tm-68k.h: Fix typos.
737 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
739 Changes from a bringup on the DEC Vax under Ultrix 4.0.
741 * coredep.c (fetch_core_registers): Pass end-address of register
742 section to register_addr as expected. Don't call supply_register
743 if we'd just pass it garbage.
745 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
747 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
749 * target.c (push_target, target_info): Cast enums to int for < or
752 * stack.c (print_frame_info): Identify source file & line
753 even if we can't print it.
755 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
757 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
759 Clean up IEEE floating point support.
761 * ieee-float.h: New file.

763 doubles and various target IEEE extendeds.
764 * m68k-xdep.c: Eliminate assembler code for extended floats.
765 * xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3,
766 sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
767 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
768 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
769 double_to_ieee_extended.
770 * i960-tdep.c: Define ext_format_i960.
771 * m68k-tdep.c: Define ext_format_68881.
772 * sparc-tdep.c: Define ext_format_sparc, though unused.
773 * Makefile.dist (HFILES): Add ieee-float.h.
774 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
777 Obsolete the "coffstrip" program in favor of using BFD's strip.
779 * nindy-share/coffstrip.c: Remove file.
780 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
781 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
782 * tconfig/nindy960: Remove reference to coffstrip.o.
784 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
786 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
788 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
789 * dbxread.c: Remove static symfile_bfd.
790 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
792 * inftarg.c (child_detach): Pop the child_ops vector if the
793 detach is successful.
794 * remote-nindy.c (nindy_create_inferior): Don't push a new
795 nindy_ops since nindy uses the same one for execution and memory
797 * core.c (core_ops): Use child_attach and child_create_inferior
798 rather than default attach and create_inferior functions.
800 Handle floating point registers in core files.
802 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
803 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
804 This version untested since BFD doesn't yet support sun3 core
806 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
807 conventions. Fix comments and style. This version has not
808 been compiled yet, since we have no HP inhouse.
809 * core.c (get_core_registers): Look for two sections, ".reg"
810 and ".reg2", and pass both to fetch_core_registers sequentially.
812 Revise directory path yet again.
814 * source.c (forget_cached_source_info): Not static any more.
815 (init_source_path): New default source path is "$cdir:$cwd".
816 (dir_command): Handle variable arguments ($cdir, $cwd).
817 (source_info): Print "Compilation directory" rather than
818 "Originally compiled in" to remind people of $cdir.
819 (openp): If the path contains $cwd, use current directory.
820 (open_source_file): If compilation directory is known, replace
821 first $cdir in path with the compilation directory.
822 (print_source_lines): Even if we can't print the lines, set the
823 current symtab and line for future commands like "info source" or
824 "breakpoint". Also, error message now contains the file name,
825 line number, and file access error message.
826 (_initialize_source): Fix help text to describe changes.
827 * main.c (cd_command): Forget cached source info when we chdir.
828 * utils.c (strstr): Add simple implementation.
830 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
832 * coffread.c (read_one_sym, init_linetable, init_stringtab):
833 Byte-swap COFF symbol tables if necessary when reading them in.
834 Use complain() to replace error message in one spot. Needs
835 corresponding change in bfd/coff-code.h to make some symbol
836 swapping routines non-static.
838 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
840 Merge changes from Eirik Fuller, for UTek.
842 * defs.h (errno): Add declaration.
843 * altos-xdep.c, arm-xdep.c, convex-xdep.c, gould-xdep.c,
844 hp300hpux-xdep.c, infrun.c, inflow.c, infptrace.c, i386-tdep.c,
845 i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,
846 remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,
847 symmetry-tdep.c, symmetry-xdep.c, umax-xdep.c, utils.c: Eliminate
848 declarations of errno.
850 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
852 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
853 <rpc/rpc.h> and <rpc/types.h>.
855 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
857 * i960-tdep.c (examine_prologue): Add new argument limit,
858 which stops the scan at the end of the prologue, or at the PC.
859 This fixes a problem where it walks down into the code for the
860 user's statements if that code looks like function prologues.
861 Mark Fox and I have been bouncing this code back and forth, making
862 small changes to it. Callers changed to match.
864 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
866 Cleanup for gdb-3.94 release final:
868 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
869 the .c files from vx-share and nindy-share, from the various
870 macros, since they are not found via ALLDEPFILES.
871 (SFILES): Add tm-i960.h.
872 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
873 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
875 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
876 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.
878 Mon Feb 25 16:02:35 1991 Cygnus John Gilmore (cygnus at oldman)
880 * am29k-tdep.c: Add contribution line.
881 (examine_prologue): Cache information about function prologues in
882 the misc-function-vector to avoid lots of references over the
883 serial line while examining instructions.
885 * core.c (core_close): New function made from cleanup_core.
887 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
888 remote-vx.c, remote.c, target.c, target.h,
889 Update target_ops vector to add attach, close, and load entries.
890 Use add_syms_addr_command, not add_file_addr_command, for
891 add_file. Break out close routine from existing code.
893 * dbxread.c (really_free_pendings): Don't free pending_blocks;
894 they are in an obstack.
895 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
897 (define_symbol): Add symbol type parameter; change callers;
898 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
899 it to influence the symbol class on the i960.
900 (define_symbol): Swap LOC_CONST's into target byte order.
902 * exec.c (exec_close): New function.
903 (exec_file_command): Call it.
905 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
906 Fix byte order of frame pointer.
907 (read_var_value): Result of 0 if var's value can't be found,
908 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
909 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
910 (locate_var_value): Use read_var_value and use its lazy address
911 as the location of the var's value. Lint.
913 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
916 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
917 obsolete Intel versions in favor of vxgdb versions.
918 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
919 code dealing with byte order of values, which Intel did in host byte
920 order rather than gdb-4's target byte order.
921 (i960_frame_chain_valid): Move to nindy-tdep.c.
922 (examine_prologue, skip_prologue, frame_find_saved_regs,
923 frame_args_address, leafproc_return, saved_pc_after_call,
924 pop_frame): Add vxgdb versions from Mark Fox.
925 (examine_prologue, frame_struct_result_address): Add code
926 to deal with the saved value of G13 (struct return address
928 (frame_args_address): Modify Mark's version to prefer the
929 saved value over the current value in the topmost frame.
930 Cache result in the frame info to avoid performance hair in
932 (print_fault): Add gdb960 code for printing faults.
933 (_initialize_i960): Actually call check_host.
935 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
936 add stub routines. FIXME, these currently just return zero!
938 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
939 (attach_command): Call target_attach, not target_open, now.
941 * infrun.c (normal_stop): Make global, not static, for vx_attach.
942 (child_attach): Rename from child_open.
943 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
944 don't confuse it with a zero step_resume_break_address.
946 * inftarg.c (child_detach): Eliminate inferior_pid test.
947 (child_files_info): Clean up message a bit.
948 (child_ops): Use child_attach, not child_open, to attach.
950 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
951 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
952 findvar.c to here, since it depends on the contents of the
953 shadow_contents of breakpoints, but keep if #if 0 since it is
956 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
959 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
960 (ptype_command, display_command): Eliminate have_inferior_p and
961 have_core_file_p in favor of target_has_stack or
962 target_has_execution.
963 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
964 code for actually finding the values of arguments, though we still
965 keep track of the maximum stack offset for use in printing unnamed
966 arguments. Handle missing FRAME_ARGS_ADDRESS.
968 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
969 (struct nindy_regs): Define registers passed to/from nindy.
970 (nindy_fetch_registers, nindy_store-registers): Translate between
971 nindy and GDB formats for the registers.
972 (dcache_init): Statically allocate the cache, since it was being
973 allocated by a malloc that was never freed anyway.
974 (nindy_create_inferior): Error, not core dump, if no exec file.
975 (nindy_before_main_loop): Use target_load, not target_add_file.
977 * remote-vx.c (net_load): Specify large timeout for load
978 requests. Allow user to break out with INTERRUPT.
979 (net_break): Remove useless code, clean up. Change callers.
980 (parse-args, skip_white_space, find_white_space): Clean up arg
981 parsing to cope with quoted strings.
982 (net_wait, net_quit): Never call error, just return status.
983 (vx_read_register, vx_write_register): Cleanup status checking.
984 #ifdef the code based on which CPU we are using (960 or 68k),
985 FIXME, this should be completely general but it isn't yet.
986 (vx_xfer_memory, vx_resume): Cleanup status checking.
987 (vx_run_files_info): Improve message.
988 (vx_load_command): Renamed from vx_add_file_command. Allow load
990 (net_ptrace): Remove unused routine.
991 (vx_wait): Adopt code from vxgdb960 to cope with broken
992 connections to target machine and prompt to disconnect. Remove
993 debug printouts. Map some EVENT_'s to SIGnals.
994 (add_symbol_stub, vx_open): Print names of object files we found,
995 and "ok" if we read their symbols OK. Clarify output in general.
996 (vx_attach, vx_detach, vx_kill): Add these commands.
997 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
998 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
999 "info files" output, and create_inferior, since we already have
1002 * stack.c (frame_info): Replace Frame_unknown with 0.
1003 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
1004 (return_command): Pop until the PC matches as well as the FP,
1005 so it works even if the FP is shared with another function,
1006 as in "frameless" or "leaf" procedures.
1008 * symfile.c (load_command): renamed from add_file_target_command.
1009 (add_syms_addr_command): renamed from add_file_addr_command.
1010 (add_syms_command): Stub to call target_add_syms.
1011 (_initialize_symfile): Change command names and descriptions,
1012 add-file => add-syms, and load from alias to its own command.
1014 * target.c (kill_or_be_killed, maybe_kill_then_attach,
1015 maybe_kill_then_create_inferior): Default for attempts to start
1016 a process, if one is already running, is to ask about killing
1017 it and retry if yes.
1018 (upstack_create_inferior): #if-0 it, strata obsolete it.
1019 (push_target, unpush_target, pop_target): to_close() a target
1020 before unstacking it.
1021 (target_info): Renamed from target_files_info.
1022 (_initialize_targets): Rename "i files" as "i target", accessible
1025 * target.h: Improve comments about the target_ vectored routines.
1027 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
1028 Convert commenting style to standard GNU style.
1029 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
1030 (SKIP_PROLOGUE): No longer a no-op.
1031 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
1032 (*_REGNUM): Sort register numbers.
1033 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
1034 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
1035 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
1036 are now 10 byte extendeds, not 8 byte doubles.
1037 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
1038 for nindy versus vxworks targets. FIXME, this should possibly go
1039 in the target vector.
1040 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
1041 frame_saved_regs and arg pointer with each frame.
1042 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
1043 (FRAME_ARGS_ADDRESS): Use cached result.
1044 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
1045 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
1046 (PRINT_RAMDON_SIGNAL): Call print_fault.
1047 (POP_FRAME): Now works.
1049 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
1050 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
1051 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
1052 (ADDITIONAL_OPTION_HANDLER): use target_load, not
1055 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
1056 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
1058 * valarith.c (value_subscripted_rvalue): Avoid handling
1059 floats and doubles specially; it gave alignment errors. Lint.
1061 * valops.c (value_of_variable, value_of_this): Error if unknown
1064 * valprint.c (print_floating): Bcopy rather than pointer-deref,
1065 to avoid alignment problems.
1066 (value_print): Handle unknown value address.
1067 (cplus_val_print): Two args are ignored; remove them. Change caller.
1068 (val_print): Use unpack_long rather than pointer-deref.
1071 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
1072 to avoid alignment problems.
1073 (value_being_returned): Error if return value unknown.
1074 (set_return_value): Add bogosity warning, FIXME. *
1076 * TODO: A woman's work is never done.
1078 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
1079 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
1080 Add ieee-float.o to OBS.
1081 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
1082 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
1083 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
1085 Changes to generalize the VxWorks RPC protocol slightly, to handle
1086 i960 as well as 68000.
1088 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
1089 * vx-share/reg.h: Produce i960 regs #ifdef I80960
1090 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
1091 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
1092 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
1093 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
1094 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
1095 so they will move in target byte order rather than network
1096 byte order (happens to be the same).
1098 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
1100 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
1102 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
1105 Add contribution lines to various files, showing where they
1108 * breakpoint.c (break_insn, check_break_insn_size,
1109 read_memory_nobpt): Remove to mem-break.c.
1111 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
1114 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
1115 entry has bad register number. This change is not
1116 tested in this release, FIXME.
1118 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
1121 * value.h: Force value's contents field to be aligned to hold
1122 at least a double or a long long (if supported). This avoids
1123 doing bcopy's in and out of the contents field.
1125 (step_1): Avoid coredump under obscure circumstances when we
1128 * symtab.h (misc_info): Add field to misc function vector for
1129 any kind of cached information the target code desires. AMD
1130 29000 uses this to avoid repeating examine_function_prologue's.
1132 * coffread.c: Lint. Remove static symfile, read_section_header.
1133 core.c (have_core_file_p): Lint: remove.
1134 expprint.c (print_subexp): Lint.
1135 infptrace.c, valops.c, valprint.c: lint.
1137 Roll in changes from vxgdb-5.0.1:
1139 * symtab.h: Comment byte order of each address class. Add
1140 LOC_LOCAL_ARG for frame-relative args (960).
1141 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
1142 symtab.c, symmisc.c: ditto.
1144 * infrun.c (init_wait_for_inferior): Clear stop_signal.
1146 * remote.c (remote_resume): Error if resume with a signal.
1148 * symfile.c (prim_record_misc_function): Clear misc_info.
1149 (fill_in_vptr_fieldno): Check stub type of arg.
1151 * valops.c (value_cast): Avoid looking up names of types whose
1152 name we don't know, to prevent coredump. Sun CC produces typedef
1153 rtx and the name of *rtx is zero...
1155 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1157 Roll in changes from final AMD 29000 port (Tiemann).
1159 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
1160 for ../include/a.out.encap.h. This might not work now that BFD
1161 is separately compiled. Instead, BFD support for encap will have
1162 to translate machine type 29k into the right COFF_MAGIC.
1164 * infcmd.c: Remove references to inferior_pid that aren't used
1165 in actual ptrace calls; use target_has_execution, etc.
1166 (have_inferior_p): Remove function.
1167 (program_info): Print target info rather than "process number";
1168 avoid gratuitous messages unless from_tty.
1169 (run_stack_dummy, finish_command): Set proceed_to_finish.
1170 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
1171 main.c: Lint. Lose have_inferior_p().
1172 inferior.h (have_inferior_p): Remove, lint.
1173 (proceed_to_finish): Add flag to ask that all regs be saved
1174 by normal_stop, for the few commands that need it, speeding up
1175 serial I/O. Add comments to stop_registers.
1177 * remote-eb.c: Remove newline from breakpoint message we grep
1178 for. Never time out when running the user program.
1182 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
1184 Roll in changes from vxgdb-5.0.1:
1186 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
1187 symbol in its raw form, we are processing an unlinked ".o" file.
1188 See if the target environment has assigned it an address, using
1189 target_lookup_symbol (VxWorks does), and enter it into the symtab
1192 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
1193 68k versions for a simpler version that assumes zero FP at bottom.
1194 Fixes bug of truncated stack reports.
1196 * target.h (target_lookup_symbol): Define this routine's args
1197 and result, finally.
1199 * target.c (nosymbol): Default routine for target_lookup_symbol.
1200 (target_default): Default lookup_symbol and call_function too.
1201 (files_info): Only print has_all_memory warning if a non-dummy
1204 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
1205 vx_convert_from_virtual): If target does not have floating point,
1206 zero register "values", and avoid doing cross-net conversions.
1207 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
1208 (vx_open): Rearrange code that attaches to target and reads
1209 symbols for all loaded modules, to work if some of the modules
1210 are not accessible. Add symbol_stub() and add_symbol_stub()
1211 as callbacks from catch_errors(). Allow connect attempt to be
1212 interrupted painlessly with ^C (FIXME, there are still some bugs
1213 if the interrupt happens during symbol reading.). Print
1214 final message with puts_filtered, since symbol messages are
1219 * main.c (catch_errors): Only print errstring if non-null.
1220 (command_loop): Avoid an ioctl per command to test ISATTY.
1222 * remote-vx.c (net_load): make static; avoid sophomoric msg.
1223 (vx_xfer_memory): Return correct result!
1224 (vx_files_info): Indicate whether target has float or not.
1225 (vx_lookup_symbol): Complain, not error, if target gone.
1226 (vx_open): Print "Connected" msg before disabling immediate-quit.
1227 [FIXME: lookup_symbol and vx_open changes need testing.]
1229 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
1230 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
1231 contributor lines and update copyrights to 1991.
1233 Changes from an attempted H-PUX host port:
1235 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
1236 defines PT_ATTACH and PT_DETACH but not PT_KILL.
1237 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
1238 * remote-vx.c: include <sys/time.h> for HPUX.
1239 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
1240 "core_file_command" routine to BFD regime. May not work yet.
1242 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
1244 * xgdb.c: Replace X10 version with some VJ version.
1245 (FIXME: Its copyright assignment is not on record.)
1246 * xgdb.c: Update include files to X11R4 (Xaw crud).
1247 (xgdb_display_source, create_text_widget): fix call to
1248 get_filename_and_charpos. Rewack source window stuff for X11R4
1249 (gleaned from include files, and "nm's" of binary libraries, since
1250 I had no doc available).
1251 (append_selection, append_selection_word): Disable with FIXME
1252 since R4 changed interface here.
1253 (create_buttons): Add back the old set of buttons.
1254 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
1256 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
1257 Roll VERSION to 3.94 (not yet final though).
1259 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1261 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
1262 obstack_int_grow, obstack_int_grow_fast): Eliminate
1263 cast on left of assignment, which gives MIPS cc fits and is
1266 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
1267 F_ALIAS. Use printf, not fprintf, when not passing a file
1269 (compare_opcodes): Check that identical instructions have
1270 identical opcodes, complain otherwise.
1272 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
1273 was reported by Roland McGrath.
1274 (unimp): Only match if exactly zero instruction. (Roland)
1275 (branches and traps): Generate all variations of these
1276 instructions with macros, based on a single call that defines
1277 each condition name and its binary representation.
1278 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
1280 * valprint.c (val_print_fields): Take, and use, format parameter.
1281 This means that "p/x struct" again prints the elements in the
1282 desired format. Changed callers.
1284 * stack.c (frame_info): Use filtered output, and indicate wrap
1285 points. Remove kludgy formatting designed to avoid line wrap.
1287 * utils.c (wrap_here): If the line is already full (because
1288 we had printed a long indent or long wrapped string), do an
1289 immediate newline-and-indent.
1291 * m68k-pinsn.c (print_insn_arg): Bugfix from
1293 instruction is incorrectly disassembled as bkpt #8.
1295 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
1297 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
1298 and then will dump core (sometimes). I traced it back to an
1299 uninitialized symfile_name in psymtab_to_symtab.
1300 (const_vol_complaint): Add quotes to message.
1301 (define_symbol): Only believe line number if gcc_compiled.
1302 Avoid allocating symbol if we will not return it.
1304 Add target strata support so that newly established targets go
1305 into their right place in the target stack (e.g. a new exec file
1306 doesn't wipe out the ability to access the running process).
1308 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
1309 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
1310 and initialize it properly in all the targets.
1312 * target.h: Document strata. Change return type of push_target.
1314 * target.c (nomemory): new function for dummy memory access.
1315 (tcomplain): Rename complain, now also used in symfile.c.
1316 (push_target): Push targets within strata. New return value shows
1317 whether new target is on top of stack or not. Always keep dummy
1319 (target_files_info): Ignore dummy target.
1321 * core.c (core_open): Warn user, and skip accessing file, if the
1322 core target is not the topmost target in the stack.
1323 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
1326 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
1327 target_ops, it doesn't belong there since we have no regs there.
1328 Change name of target from machine => memory to clarify.
1330 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
1332 * Freeze version 3.93 for release.
1334 * Makefile.dist: Handle vx-share and nindy-share subdirs
1335 properly when building gdb.tar.Z.
1337 * symtab.c: lint; add no_symtab_msg to consolidate the messages
1338 printed in various places, so I could change just one copy.
1340 * dbxread.c, coffread.c: Change references to bfd->iostream
1341 to cast to FILE *, now that BFD avoids needing types defined
1342 in other header files.
1344 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
1346 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
1347 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
1348 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
1349 (actually gcc -Wall).
1351 * dbxread.c: Remove first_global_sym, last_global_sym, since
1352 they are never referenced.
1354 * defs.h (baud_rate): Declare.
1355 main.c: Define it, and add the -b option to set it.
1357 * gdb-int.texinfo: Add text on how to define a new host or target
1358 architecture, prompted by Per Bothner's questions about MIPS
1361 * gdb.texinfo: Document "complaints". Change doc of -q since
1362 gdb no longer prints the copyright and blurb if you specify a file
1363 name to be debugged (just like Emacs). Add doc for Nindy-specific
1364 command line flags for specifying target serial port and such.
1365 Update copyright to 1991.
1367 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
1368 has taken over for us the job of ripping up executable files. The
1369 crud caused Per Bothner's port to not compile.
1371 * infrun.c (normal_stop): Avoid printing "Program exited
1372 normally" if we are in batch mode. This allows a GDB which
1373 executes a program on a target system, to behave like a Unix
1374 command (input from stdin, output to stdout, no extraneous
1377 * main.c (main): Allow additional machine-dependent command line
1378 options to be specified with the ADDITIONAL_OPTIONS,
1379 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
1380 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
1381 processing to occur just before the main loop with
1382 BEFORE_MAIN_LOOP_HOOK.
1383 (main): If a "core file" argument is specified, and it is not a
1384 core file, try it as a process ID to attach.
1385 (symbol_completion_function): Attempt to cope with
1386 "show screen-" TAB, not very successfully. This needs more work,
1388 (batch_file): New function, returns whether we are reading
1389 commands from an interactive tty on stdin, or from somewhere else.
1390 Called by normal_stop since it doesn't get from_tty passed down
1391 to it like many commands do.
1393 * remote-nindy.c: Handle command line options for nindy
1395 (nindy_before_main_loop): Prompt user for tty name if they
1396 don't specify it before getting to the interactive command loop.
1398 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
1399 and -r command line options. Also add hook before main loop
1400 to make it easy to specify a tty.
1402 * TODO: More things to do, one done.
1404 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
1406 * dbxread.c: Make complaint() calls pass pointer, not struct.
1407 Add complaints about badly formatted C++ type information
1408 (const/volatile indicator, and parse errors resulting in
1409 error_type). Fix C++ virtual member fn comment.
1410 (read_struct_type): Avoid bumping pointer if we got a parse
1411 error; this prevents our walking beyond the end of a string.
1412 Terminate loop on null char as well as semicolon.
1413 (process_one_symbol): Fix the LBRAC fix so that it uses the
1414 last previous SLINE, FUN, or SO record's PC address. C++ debug
1415 symbols did not have SLINE records in a useful order compared
1416 to the LBRAC records.
1417 (define_symbol): Handle "catch" records.
1419 * symtab.c (check_stub_type): Added new complain
1420 `stub_noname_complain' and added a consistency check to
1421 keep the debugger from crashing when finishing from an
1422 exception frame. A real fix will be needed later.
1424 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1426 * infcmd.c (attach_command): Make global.
1428 * Makefile.dist (REMOTE_OBS): Make these compile by default,
1429 but make them easy to comment out. Perhaps later they should
1430 be enabled by what CPU you configure for? FIXME.
1431 (VERSION): Roll to 3.93.
1432 (pinsn.o): Remove rule for obsolete file.
1433 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
1435 Run down a problem that manifested by printing the wrong function
1436 name in stack traces of read_ofile_symtab. Turned out that the
1437 problem was the SunOS 4.1.1 (and previous) C compiler outputs
1438 the LBRAC symbol with an address in the *data* segment, which
1439 blew our binary search through the blocks.
1441 * dbxread.c: Use the complain() facility consistently to bitch
1442 about problems in the symbol file we are reading.
1443 (finish_block): Add code to check the nesting of the blocks;
1444 complain and Procrust them to fit if wrong.
1445 (make_blockvector): Check the order of the blocks, complain
1446 [but don't cope] if wrong.
1447 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
1448 symbols to be sure their PC value is greater than the last SLINE
1449 (line number) symbol we've seen, complaining and adopting the
1450 SLINE PC value if wrong.
1452 * symfile.h (struct complaint, complaint_root, complain,
1453 clear_complaints): Add.
1454 * symfile.c (complain, complaint_root, clear_complaints): Add
1455 facility to deal with non-fatal complaints and to regularize their
1457 (symbol_file_add): Clear complaint counters to allow new complaints.
1458 (initialize_symfile): Add 'set complaints' and 'show complaints'.
1460 * dbxread.c (dbx_symfile_read): Remember the address and size
1461 of the string table for the main symbol file, so we won't read it
1463 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
1464 to avoid reading the string table yet again. Lint.
1465 (throughout): Improve filtered output, including word wrap.
1466 (read_range_type): Improve Bothner's fix to handle other types too.
1468 * utils.c: Improve line wrap implementation. Handle unlimited
1469 width by making chars_per_line unsigned.
1470 (puts_filtered): New, easy, function.
1472 * defs.h (puts_filtered): add.
1474 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
1475 call the identical sort_symtab_syms() in symfile.c instead.
1477 * expread.y: Suggest the `file' command rather than `symbol-file'.
1479 * command.h (enum var_types): Add zinteger for seroable
1481 * command.c (do_setshow_command): Handle var_zinteger. Restructure
1482 nested if's into a switch.
1484 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
1485 we did not stop because of a breakpoint (it must have been for
1486 some other reason, like a "stepi"), so don't print anything.
1488 * symtab.c: Include <sys/types.h> all the time. Now that BFD
1489 doesn't include <sys/types.h>, old SunOS's require it for
1494 A test port of gdb-3.92.6 to the Sony NEWS.
1497 Don't normally link in remote- or vx stuff.
1498 Some of it doesn't compile, and it wastes space for 99% of the users.
1499 Remove reference to no-longer-used HAVE_VPRINTF.
1500 Fixed BFD_DEP typo to BFD_DIR.
1502 Fix cast in arg to bfd_h_getlong.
1503 Make char *prefix be const.
1504 Fix how certain range types are mapped into builtin unsigned int types.
1506 Remove 2 #includes. They cause errors (on Sony, at least),
1507 and aren't needed (they wern't in earlier versions).
1509 print_address_symbolic should never demangle labels
1510 (since it prints *assembler-level* labels).
1512 [This was superseded by the change to printcmd below.]
1515 Add some "volatile" return types to avoid warnings.
1516 If MISSING_VPRINTF add vprintf function and not just macro
1517 (since vprintf is used in printcmd.c).
1519 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
1520 (The latter isn't grokked by some PCC-based compilers.)
1522 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
1524 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
1525 * nindy-share/coffstrip.c
1526 Added some forward declarations (otherwise, gcc complains
1527 about implicit extern redefined as static).
1529 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
1531 Changes inspired by Per Bothner:
1532 * printcmd.c (print_address_symbolic): Take additional parameter
1533 specifying whether to demangle.
1534 (print_address): Pass in asm_demangle to control demangling.
1535 (print_address_demangle): New fn, takes explicit arg to control
1537 * utils.c: Add new vars demangle and asm_demangle, and let them
1539 (fputs_demangled): If !demangle, just print the argument.
1540 (fprint_symbol): If !demangle, just print raw symbol.
1541 * valprint.c (val_print): Call print_address_demangle rather than
1542 print_address, to cause demangling to depend on the global
1543 rather than assembler-level demangling setting.
1544 * WHATS.NEW, gdb.texinfo: Document.
1546 * main.c (show_command): Show all settings if no arg.
1547 (initialize_main): Make "info set" the same as naked "show".
1548 * command.c (cmd_show_list): Handle prefix commands in the
1549 list, and print the name of the setting as well as its English
1550 description and value.
1552 Allow gdb functions to specify where a line should wrap if it
1553 exceeds the size of a terminal line. Use it to make the output
1555 * utils.c (set_screen_width_command): New fn, mallocs a buffer
1556 of the right size when screen width changes.
1557 (set_screensize_command, screensize_info): Remove #if 0'd fns.
1558 (wrap_here): New fn, indicates a point in the output where we
1559 should wrap the line rather than just letting it overflow at a
1561 (fputs_filtered): Implement wrapping.
1562 (n_spaces): New fn, returns a pointer to N spaces.
1563 (print_spaces_filtered): Use n_spaces.
1564 * defs.h (n_spaces): Declare.
1565 * stack.c (print_frame_info): Wrap with 4-space indent after
1566 fn name and before filename and line number.
1567 * printcmd.c (print_frame_args): Wrap with 4-space indent
1568 before each argument name is printed.
1569 * valprint.c (value_print): Wrap with no indentation before
1571 (val_print_fields): Wrap with indentation relative to nesting
1572 level before each field name.
1573 (val_print): Wrap with nesting indentation before array elements.
1574 * command.c (do_setshow_command): Avoid extra newlines,
1575 wrap with 4-space indent around values printed, end with period.
1576 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
1578 * breakpoint.c (breakpoint_1): Implement addressprint for
1579 "info breakpoints" display. Change file name and line number
1580 format to " at file:nnn" rather than " (file line nnn)".
1581 * gdb.texinfo: Document.
1584 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1586 Frozen for gdb-3.92.6 release.
1588 README, WHATS.NEW: Update for 3.92.6 release.
1590 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
1591 coffread.o from configs since it is now built by default.
1592 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
1593 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
1594 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
1595 from configs since it is now built by default.
1597 Makefile.dist: Update for release 3.92.6. Handle files that
1598 have been moved to ../include, ../getopt, or ../bfd. Add
1599 saber.suppress and tests directory. Add config.status to
1600 the release (it will say "none").
1602 coredep.c: Minor formatting fixes.
1604 These changes were made in early December but only checked in now:
1605 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
1606 nindy-share/nindy.c: lint
1607 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
1608 register values coming back from the target; we store values
1609 in target byte order everywhere.
1611 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
1613 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
1615 * valprint.c (cplus_val_print, val_print_fields): New functions,
1616 which print C++ objects. They conspire to avoid printing a
1617 virtual base class more than once, following all the twists and
1618 turns of C++ virtual base rules.
1619 (val_print): Call the above rather than do it by hand.
1621 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
1622 symbol file, not for added files like shared libs. This really
1623 needs to be generalized to a timestamp per file.
1625 * core.c (cleanup_core): Avoid coredump if no core file.
1627 * config.gdb: Accept -host or -target in place of +host or
1630 * coffread.c (find_linenos): Avoid desupported BFD interface
1631 to line numbers. We still read them manually rather than using
1632 BFD's "generic" features.
1634 * gdbrc.tex, threecol.tex: Add GDB reference card and its
1636 Makefile.dist: Add refcard to OTHERS list for creating tar files.
1638 * Makefile.dist: Eliminate use of $< in explicit targets.
1640 * readline/Makefile: Use $< rather than $*.c, which does not
1641 include the VPATH in GNU Make.
1643 * tconfig/i960-bout, tconfig/i960-coff: These are identical
1644 copies of tconfig/i960, added for global configuration
1645 compatability. All i960 versions can read both coff and b.out.
1647 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
1648 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
1651 * TODO: Think of more things to do.
1653 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
1655 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
1656 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
1657 64-bit float conversion.
1659 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
1660 equivalent to sun?os4 so global config works.
1662 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
1666 * main.c: Only declare linesize once; declare pagesize not at
1667 all, since it is never used.
1668 (main): Clear newly allocated line before it is used.
1670 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
1672 Further stabilization for the Intel 960.
1674 * Makefile.dist: Parameterize the location of the "include"
1675 and "bfd" directories, as well as "getopt". Add symfile.c.
1676 Link in both dbxread and coffread. Fix up "make depend" to
1677 rewack the locations of include, bfd, and getopt in its output.
1679 * README: Document moving include files, improve some of
1682 * coffread.c: Move common code out to symfile.c. Change
1683 symbol_file_command style interface to use new *_symfile_init
1684 and *_symfile_read interface under BFD. Use BFD internal
1685 info to locate line table, symbols, etc.
1687 * core.c (core_fetch_registers): Rename to get_core_registers
1688 to avoid confusion with fetch_core_registers.
1689 (register_addr): Move to coredep.c, which is already machine
1690 dependent. This leaves core.c pretty clean of dependencies.
1692 * coredep.c (register_addr): Accept this routine from core.c.
1694 * dbxread.c: Move common code (with coffread.c, etc) into new
1695 symfile.c. Each psymtab now contains a pointer to the
1696 format-dependent function that knows how to read it in. Make
1698 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
1699 (process_one_symbol): Add code to complain about a "compiler bug
1700 we muzzle here", if we actually see it.
1702 * eval.c (evaluate_subexp): Insert missing "break" statements
1703 in code that determines whether a variable is an lvalue in
1704 memory, register, or whatever. I detected this via a compiler
1705 bug in which it *almost* mashed out the whole switch statement.
1707 * gdb-int.texinfo: Add minor sections on configuring gdb for
1708 release, and about the README file.
1710 * infcmd.c (registers_info): Fix formatting somewhat. Still
1711 not as pretty as before, but it handles byte swapping.
1713 * remote-nindy.c: If data cache routines are interrupted while
1714 waiting for the remote end, be sure that any uninitialized cache
1715 blocks are on the free list, not on the valid list!
1717 * symfile.h: Flesh out this header file with all the various
1718 routines and variables that have been merged in from dbxread.c
1719 coffread.c, and symtab.c to symfile.c.
1721 * symfile.c: New file, containing code common to dbxread.c,
1722 coffread.c, and some code from symtab.c. All generic code for
1723 reading symbol files should be in here now.
1724 (unrecord_misc_function): Remove unused function.
1726 * symtab.h: Remove file-reading things to symfile.h.
1728 * symtab.c: Remove file-reading things to symfile.c.
1730 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
1731 to decode i960 fault types.
1733 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
1734 target.c: Change type of the "resume" function from int to void,
1735 since its result was never used.
1737 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
1739 * main.c: Replace "stupid" with "caution"; you now "set caution
1742 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
1744 * infcmd.c (do_registers_info): Call val_print to deal with the
1745 byte order of the registers being printed. FIXME, this makes
1746 the formatting of the output uglier.
1748 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
1749 defined, call it for signals the debugger doesn't itself use.
1750 The i960 uses this for more detailed fault information.
1752 * remote.c (remote_open): If arg is null, print help rather than
1755 * sparc-xdep.c (register_valid): Avoid declaring size, since
1756 various modules will think of various sizes depending on the
1757 architecture of their tm-file. FIXME, we need protection against
1758 actually entering one of those modules, which would clobber
1759 storage if not for the target architecture compiled into gdb.
1761 * stack.c (up_command, down_command): Always print the frame
1763 (up_silently_command, down_silently_command): New commands
1766 * i960-pinsn.c (reg), i960-tdep.c: Lint.
1768 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
1769 more parameters than it used to.
1771 * findvar.c (registers): Increase slop to 256 bytes, which should
1772 protect us against even most RISC machines with large register
1774 (locate_var_value): Move declaration inside related ifdef.
1776 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
1777 throughout, to avoid throwing away buffered input from the board.
1778 (nindy_wait): Supply_register takes addr_of_value, not value.
1779 (i960_print_fault): Renamed from i80960_fault.
1780 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
1781 (nindy_store_registers): Avoid regs_changed stuff, just stuff
1783 (nindy_create_inferior): Don't bother to write PC_REGNUM since
1784 we can set the PC in the call to proceed(). Unpush nindy_ops
1785 before pushing it on top, to avoid message to user. Eliminate
1786 commentary from Unix machines that just misleads here.
1787 (reset_command): Fix error message to suggest target command.
1789 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
1791 Release 3.92.5 as frozen.
1793 Stabilize the merged release...with help from lint, Saber C,
1796 Everywhere: Add include files needed to declare return types
1797 of functions called.
1799 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
1801 * breakpoint.h: Add undeclared breakpoint functions, and some
1802 functions for display handling since I couldn't think of a better
1805 * breakpoint.c (insert_breakpoints): Make code for disabling
1806 shared library bkpts more likely to work. It's used when we
1807 rerun a program and stop before the shared library has been
1809 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
1810 cast from pointer, so it squeezes through catch_errors.
1811 (bpstat_stop_status): Fix logic broken some time ago. We now
1812 always create a bpstat if the stop address matches a breakpoint,
1813 even if we don't stop there -- just like the old code used to do
1814 before I got my fingers into it (sigh).
1815 (breakpoint_1): Print "ignore count" after "stop only if"
1816 condition, since that's how it actually works.
1817 (mention): Handle watchpoints as well as breakpoints.
1818 (watch_command): use set_raw_breakpoint and mention to do most
1819 of the work (and initialize all the fields!). Only pass one
1820 arg to parse_c_expression, since that's all it takes.
1822 * command.c (not_just_help_class_command): Rename arg to args
1823 since we ignore "unused argument" warnings on vars named "args".
1824 inflow.c (child_terminal_info): ditto.
1825 infptrace.c (kill_inferior): ditto
1826 main.c (catch_errors, version_info, quit_command, pwd_command,
1827 source_command, dump_me_command, editing_info,
1828 set_history_size_command, set_history, show_history,
1830 stack.c (locals_info): ditto
1831 target.c (target_files_info): ditto
1832 valprint.c (set_input_radix, set_output_radix): ditto
1834 * core.c: Remove old variables for handling core and exec file
1835 sections (data_start, data_end, stack_start, stack_end,
1836 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
1837 text_end, exec_data_start, exec_data_end, text_offset,
1838 exec_data_offset, data_offset, stack_offset). They're
1839 superseded the more general build_section_table and
1841 (get_exec_file): Mention the `file' command.
1842 (read_memory_check): Rename to memory_error, and only call it
1843 in the case of an actual error.
1844 (read_memory, write_memory): call memory_error.
1845 (core_fetch_registers): Register section name is ".reg".
1847 coredep.c: Remove a bunch of crud now that all this file does
1848 is pull the registers out of a core file.
1849 (fetch_core_registers): Rewrite to actually work, I hope.
1851 dbxread.c: Use a.out.gnu.h, not system a.out, now.
1852 Replace index() with strchr(). Remove all the pre-BFD macro
1853 definitions for accessing the symbol file.
1854 (struct dbx_symfile_info): Encapsulate the information that
1855 dbx_symfile_init needs to pass to dbx_symfile_read in this
1858 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
1859 dbx_symfile_discard): Rearrange symbol file reading to divide
1860 the format-specific part from the format-independent part,
1861 leaving the format-independent part such as file name expansion
1862 and opening in symtab.c. This replaces
1863 partial_symbol_file_open and partial_symbol_file_read.
1864 Symbol_file_read, add_file, add_file_target_command,
1865 add_file_addr_command move to symtab.c. Pass an explicit
1866 "mainline" flag for when reading the main symbol table, rather
1867 than relying on the offset address to be zero or nonzero.
1869 (dbx_symfile_read): Don't allow void *'s to be printed as
1871 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
1872 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
1873 macro" debug version really work.
1874 (read_dbx_symtab): Remove unref'd parameter inclink.
1875 Avoid swapping N_SLINE symbols, for speed.
1876 Merge N_TEXT!N_EXT case with the other external symbol
1877 definitions' case. Add comments.
1878 (start_psymtab): Allocate the symfile name in the psymtab on
1879 the psymbol_obstack, rather than using the caller's storage.
1880 (end_psymtab): Only allocate a dependencies list if there are
1882 (psymtab_to_symtab_2): Use BFD when reopening file to read
1883 its symbols for real.
1884 (read_struct_type): Add FIXME comments where it needs work
1886 (read_huge_number): Add FIXME about overflows.
1887 (read_range_type): Add FIXME about comparing a long to 1<<32.
1889 * coffread.c: Minor changes to move things closer to the new
1890 regime with symtab.c and dbxread.c Major work is still needed
1893 * exec.c (exec_file_command): Remove old variables (see core.c
1895 (xfer_memory): If memory transfer is right at the end of a
1896 section, don't lose.
1898 * findvar.c (get_saved_register): If value is in a real
1899 register, LVAL is lval_register, not lval_memory.
1901 frame.h: Declare print_sel_frame and record_selected_frame.
1903 gdb-int.texinfo: New file, for GDB internals documentation.
1904 Very simple, unformatted doc of cleanups is there for now.
1906 gdbcore.h: Remove obsolete variables that described a.out
1907 section addresses and offsets. (See core.c above.)
1908 Declare fetch_core_registers and registers_fetched.
1910 getopt.c: Declare char *alloca(); even on SPARC.
1912 infcmd.c (run_command): Call target_kill rather than
1914 (step_command, next_command, stepi_command, nexti_command):
1915 Declare from_tty parameter even though we don't use it.
1916 (run_stack_dummy): argument BUFFER is a char array, not
1917 a pointer to REGISTER_TYPE.
1918 (finish_command): using_struct_return needed a value *,
1919 not a struct symbol *.
1921 * infptrace.c (child_xfer_memory): To avoid dependency on
1922 where sections are in memory, try PT_WRITE_D and if that fails,
1923 try PT_WRITE_I. Most Unixes don't care which you use.
1925 * infrun.c (step_resume_break_shadow): Change to array to
1926 match other breakpoint shadow storage.
1927 (clear_proceed_status): Pass address of bpstat to
1928 bpstat_clear, not the bpstat itself.
1929 (child_create_inferior): FIXME comment about if the child
1931 (start_inferior): Remove old function.
1932 (child_open): Use target_kill rather than kill_inferior.
1933 (wait_for_inferior): Ditto.
1934 (insert_step_breakpoint, remote_step_breakpoint): Use
1935 new step_resume_break_shadow.
1937 * inftarg.c (child_wait): If all child processes die,
1938 pretend that the one being waited for exited with signal 42.
1940 * main.c (command_line_input): When scanning for comments,
1941 don't coredump on unclosed quotes.
1942 (quit_command): Use target_kill rther than kill_inferior.
1943 (_initialize_main): Rename class_user from "user" to
1946 * printcmd.c (print_command_1): Initialize "fmt" if no format
1947 is specified by the user.
1948 (print_frame_args): Only add to args_printed if we are
1949 actually fetching args from the stack (avoiding undefined
1951 (_initialize_printcmd): Remove bogus \{ from string.
1953 * remote-eb.c (eb_open): Avoid coredump on no argument.
1955 * remote-nindy.c: Bring out of Intel environment into new
1956 target environment. Remove all conditional compilation on
1957 I80960. Massive hacking throughout.
1958 (nindy_xfer_inferior_memory): New routine stolen from
1960 (nindy_create_inferior): New routine pieced together, probably
1961 not quite working yet.
1962 (nindy_ops): New target_ops struct for nindy.
1964 * remote-vx.c: Use write_memory rather than target_write_memory
1965 to get error checking.
1966 (vx_add_file_command, vx_open): Use symbol_file_add rather than
1968 (vx_create_inferior): Use target_terminal_ours...
1970 * signame.c (_initialize_signame): Always initialize, since
1971 we need the table for things other than psignal.
1973 * solib.c (solib_add): Use symbol_file_add, not add_file.
1974 (solib_address): Return boolean result rather than struct
1975 pointer which nobody else knows the type of.
1977 * sparc-tdep.c, valops.c: Use write_memory rather than
1978 target_write_memory, to get error checking.
1980 * stack.c (locals_info, catch_info, args_info,
1981 get_selected_block, frame_command, up_command): Use
1982 target_has_stack, rather than have_inferior_p or
1985 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
1987 * symfile.h: New file, defining the interface between the
1988 generic and object-file-specific symbol reading code.
1990 * symtab.c: Move generic symbol-reading interface to symtab.c,
1991 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
1992 table to map BFD targets to symbol-reading modules in GDB.
1993 Change index to strchr.
1994 (lookup_struct_elt_type): Use error() rather than hand-made
1995 simulations thereof.
1996 (lookup_partial_symbol): Speedup slightly when length == 0.
1997 (symbol_file_add): New function.
1998 (symbol_file_command): Call it.
1999 (symfile_open, symfile_init): New function.
2000 (add_file_target_command, add_file_addr_command): moved from
2003 * target.c (target_command): use target_kill.
2005 * target.h (target_files_info): Don't declare, never called
2008 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
2009 files to determine stack end address.
2011 * valarith.c (value_x_binop, value_x_unop): Change error message
2012 to be more useful. Pass proper argument to value_struct_elt.
2014 * valops.c (value_assign): FIXME comment that long long
2015 bitfields will break here.
2017 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
2018 Update `make saber_gdb' to work better.
2020 * TODO: A woman's work is never done.
2022 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
2023 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
2024 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
2025 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
2026 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
2027 valops.c, valprint.c, exec.c: Lint.
2030 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
2032 Continuing Intel 960 port merge of GDB.
2034 * Makefile.dist: Merge i960 "nindy-share" files. Rename
2035 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
2036 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
2037 Wack over "make depend" so it handles files in subdirectories
2038 vx-share, nindy-share, bfd, and in the current directory.
2040 * blockframe.c (get_prev_frame_info): Remove fatal error
2041 if stack not defined.
2043 * core.c (core_open, core_detach): New functions that handle
2044 the old "core-file" command as "target core" and "detach" instead.
2045 (core_file_command): Call them.
2046 (core_xfer_memory): Use common routine xfer_memory.
2048 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
2049 dbxread now uses bfd for everything but symbol reading itself.
2050 BFD internals are used to drag out the relevant file offsets.
2051 (partial_symbol_file_open): Change args all around for BFD.
2053 * symtab.c: Rename "value" to "val" everywhere, so we can
2055 (symbol_file_command): New command, moved from dbxread.c
2056 and coffread.c. It uses BFD to read the file, then vectors
2057 based on its type, to dbx or coff symbol readers.
2058 * symtab.h: Extern a few vars for symbol_file_command.
2060 * target.h: Breakpoint takes a char * save area, not a char **.
2062 * valprint.c (val_print): When unpacking bitfields, offset
2063 the address in gdb of the value, if it is declared with a shorter
2064 type. Remove the last "runtime kludge test" of host byte order.
2066 * utils.c: Remove old my_bfd_read routine.
2068 * stack.c (frame_info): Use target_has_stack. Print program counter
2069 register's actual name rather than "pc", since it's called the
2070 "ip" (instruction pointer) on the i960 (sigh).
2072 * target.c (target_command): Add command for selecting a target
2073 type and calling its open routine. This is used for initiating
2074 communication with a particular target, in a generic way.
2076 * tm-i960.h: Update for modern gdb. Remove semicolons from
2077 various macros. Handle reading struct return convention, and
2078 error-out attempts to return structs with the "return" command.
2079 Be sure gdb doesn't think we know how to call functions in the
2082 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
2083 to i960_xxx in lower case.
2084 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
2085 not being defined yet.
2087 * remote.c (remote_open): Call start_remote to initialize
2088 wait_for_inferior during open.
2089 (remote_xfer_inferior_memory): Return length written rather
2092 * remote-vx.c (target_command -> vx_open): Use new generic
2094 * remote-eb.c, inftarg.c, exec.c: ditto.
2096 * infrun.c: Fix comments.
2097 (attach_program -> child_open): Use new generic target command.
2098 (wait_for_inferior): Clear saved register values before target_wait,
2099 so target_wait can set some of them if convenient.
2101 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
2102 Return success indicator, not void.
2103 (child_xfer_memory): Avoid fetching initial word if we'll
2104 overwrite it anyway.
2106 * infcmd.c (attach_command): Use new generic target open routine.
2107 (_initialize_infcmd): Update doc on attach and detach commands.
2108 (do_registers_info): Merge in a byte-order problem as a FIXME
2111 * findvar.c (find_saved_register): Avoid problem in current frame.
2112 (read_relative_register): Ditto.
2113 (write_register): Convert byte order on the way out.
2115 * exec.c (file_command): Add.
2116 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
2117 (xfer_memory): Common function between core_xfer_memory and
2119 (exec_xfer_memory): Use it.
2121 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
2123 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
2124 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
2125 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
2127 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
2129 Merge Intel 960 port of gdb, continuing...
2131 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
2132 symbol_file_command): Pass from_tty arg to hush 'em up.
2134 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
2135 Add magic numbers for 960 COFF format.
2137 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
2139 Merge Intel 960 port of gdb, from Intel "1.2" release.
2141 CHANGE_LOG entries from their port, which was based on
2144 Thu Sep 6 11:02:22 PDT 1990
2145 Remove temp file if download is interrupted.
2147 Wed Aug 1 09:08:33 PDT 1990
2148 Now uses binary protocol to talk to NINDY.
2149 Old hex protocol (NINDY 2.13 and older) supported with -O switch.
2150 Times out after 5 seconds when trying to talk to NINDY.
2152 Tue May 29 12:54:49 PDT 1990
2153 Added variable baud rate (-b switch).
2154 Source code reorganization.
2156 Thu Apr 26 11:09:55 PDT 1990
2157 More cleanup of batch mode; specifically, execute "-s", "-e", and
2158 "-se" switches as soon as they are encountered on the invocation line.
2160 Fri Apr 20 13:47:15 PDT 1990
2163 Thu Apr 19 09:54:28 PDT 1990
2164 Add 'reset' command.
2166 Wed Apr 18 09:48:07 PDT 1990
2167 After opening remote tty, wait for 1 second to go by without input
2168 from it before trying to talk to NINDY (fixes problems with the
2169 Heurikon HK80/V960E).
2171 Mon Apr 4 16:33:05 PDT 1990
2172 Some output was not being suppressed in 'batch' mode.
2174 Thu Mar 22 15:31:11 PST 1990
2175 Ask user if old symbol table should be deleted when new file is
2178 Allow user to run a program downloaded before gdb960 was brought up.
2180 Correct "exec-file" help message for i80960 context.
2182 Correct bug in calculating user space address: could occasionally
2183 corrupt user program.
2185 Make sure to zero low-order bits in rip's because of bug in 960CA
2186 A-step part: could cause operation faults when "next"ing across
2189 Correct bug that made it impossible to get source line numbers for
2190 code loaded at addresses higher than 0x7fffffff.
2192 Wed Jan 10 12:43:22 PST 1990
2193 Open remote tty for exclusive use.
2195 Fri Jan 5 12:14:42 PST 1990
2196 Correct disassembly (CA manual was right after all):
2197 opcode for sysctl is 0x659
2199 Mon Oct 23 12:03:04 PDT 1989
2200 Use G960BASE and G960BIN environment variables to find 'sx' utility.
2202 Mon Oct 16 14:15:09 PDT 1989
2203 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
2205 Mon Oct 2 15:56:31 PDT 1989
2207 Added 960CA disassembly support.
2209 To simplify maintenance:
2210 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
2212 - eliminated opcode.h: incorporates tables into i960-pinsn.c
2213 - moved 960-specific routines from i960-pinsn.c to i960-md.c
2214 - made disassembly interface identical to that in gdmp960.
2218 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
2220 * target.h: Allow targets to stack. Add target_has_memory,
2221 _registers, etc. Restructure memory access and "info files"
2222 to walk the target stack.
2223 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
2224 target.c: Change tables to match target.h.
2225 * inflow.c (child_mourn_inferior): pop child_ops.
2226 (generic_mourn_inferior): Use new has_stack flag.
2227 * infptrace.c (child_xfer_memory): New memory regime.
2228 * inftarg.c (child_files_info): New "info files" regime.
2229 * remote-eb.c: New memory regime, new info files.
2230 * remote-vx.c: New memory regime, new info files. Now use
2231 separate targets for VxWorks attachment to machine, and
2232 actually running a process under VxWorks, since one has
2233 stack & execution & regs and the other doesn't.
2234 * remote.c: New memory regime, new info files.
2235 * sparc-xdep.c (fetch_core-registers): New memory regime.
2236 * target.c: New routines and support for stacked targets,
2237 new memory regime, new info files regime.
2240 Generalize section handling for an arbitrary number of sections,
2241 including use of the new BFD (binary file) library.
2242 * gdbcore.h: Add struct section_table.
2243 * exec.c (build_section_table): Iterate all sections and
2244 record what gdb needs to know about them.
2245 (exec_command): Use it.
2246 (exec_xfer_memory): Use the table.
2247 (exec_files_info): Print the table.
2248 * core.c (core_file_command, core_xfer_memory, core_files_info):
2250 * source.c (find_source_lines): Use bfd_get_mtime.
2251 * dbxread.c: Quick changes to make it compile with new BFD.
2252 * utils.c (error): Avoid using bfd_error in generic routines.
2254 * core.c (core_fetch_registers): Get from the ".regs" section of
2256 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
2258 * inferior.h (attach_flag): Export.
2259 * infcmd.c (run_command): use new target_create_inferior.
2260 * infrun.c (child_create_inferior): Don't return result.
2261 * Makefile.dist (VERSION): 3.91.4.
2263 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
2265 * breakpoint.c (bpstat_num): Handle breakpoints which have
2266 since been deleted, such as temporary breakpoints.
2267 infcmd.c (program_info): ditto.
2269 * core.c (core_file_command): Display the frame where the core
2274 * remote-vx.c (target_command): Merge in target command from
2275 targ-vx.c. A few other cleanups.
2277 * TODO, Projects: Lots more stuff to do...
2279 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
2281 Massive changes to wall off the remote-debugging interface
2282 behind a function vector. The port to handle VxWorks targets
2283 is also part of this.
2285 All files: Replace references to renamed functions,
2286 remove references to remote_debugging, remove references to
2287 have_include_file, have_core_file in favor of target_has_stack,
2288 target_has_memory, etc.
2290 * Modularize the breakpoint interface.
2291 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
2292 a breakpoint instruction.
2293 breakpoint.c: struct breakpoint's shadow_contents now sized as
2295 (insert_breakpoints): Vector to target to install breakpoints.
2296 (remove_breakpoints): Vector to target here too.
2297 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
2298 sparc-tdep.c (single_step): Use new breakpoint interface for
2299 the single-step breakpoints.
2300 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
2301 New file, contains routines to insert and remove breakpoints by
2302 reading out the old contents and later replacing them. This is
2303 how ptrace breakpoints work, and many remote systems as well.
2305 * tm-vxworks68.h: New config file, overrides a few things for
2306 Wind River's preferences.
2308 * target.h: New file, for transfer vector used to talk to the
2309 inferior (child, attached, core, exec, remote, etc). All accesses
2310 to the thing being debugged should come through these vectors.
2311 target.c: New file, routines to handle transfer vector.
2312 (various files): Add transfer vectors XXX_ops for the various
2313 targets and pseudo-targets (core files, etc) we support.
2315 * breakpoint.c (bpstat_stop_status): Further explorations of
2316 watchpoints and why things don't work all the time.
2317 (bpstat_alloc): New fn to allocate a bpstat and chain it.
2319 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
2320 the local gdbinit if it doesn't already have it.
2322 * core.c (core_ops): add and install.
2323 Allow core debugging without exec file.
2325 * dbxread.c (free_and_init_header_files): Merge two fns.
2326 (end_symtab): Free named symbol table when a new version comes in.
2327 (read_dbx_symtab): Relocate all kinds of symbols with base
2328 address. First step toward handling different text, data, bss
2330 (add_file_addr_command): Renamed add_file_command.
2331 (add_file_command): Vector to remote handler.
2332 Add "load" as an alias for "add-file" command.
2334 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
2335 non-returning functions.
2337 * exec.c: Add exec_ops, and push it as a target when an exec
2340 * infcmd.c (run_command): Pass executable file name and arg list
2341 separately when starting an inferior. Permit "run" when no exec
2342 file is specified, for VxWorks.
2343 (detach_command): Move to child_detach in inftarg.c.
2345 * inftarg.c: New file. Unix-child-specific routines, and the
2346 child_ops structure.
2348 * inferior.h (registers): Export "registers" as the way for
2349 target dependent register handlers to find gdb's local copy of
2350 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
2351 since it is now used by places that want wait_for_inferior to
2352 handle the grunge but want to see every trap from the inferior.
2354 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
2355 Eliminate remote_debugging hooks in terminal handling.
2357 * infrun.c: Replace start_inferior with child_create_inferior.
2358 Move all the hair of Unix shells and ptrace idiosyncracies into
2359 child_create_inferior, so remote handlers don't have to deal.
2360 Remove running_in_shell. Rename stop_after_attach to
2361 stop_soon_quietly, and use it in a few other places where we want
2362 to just call wait_for_inferior and get control back on the first
2363 trap. trap_expected now never takes a value > 1.
2364 (init_wait_for_inferior): Initialize static vars when a new
2367 main.c (gdbinit): Add new hook for .gdbinit file name, let
2368 it be overridden by config files as GDBINIT_FILENAME.
2369 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
2370 Both of these are used for VxWorks gdb.
2372 mcheck.c: rename include file "gmalloc.c" to avoid problems
2373 with system include file "malloc.c".
2375 param-no-tm.h: New include file, same as param.h but does not
2376 include the default "tm.h" file. This is used in files where
2377 the target is known, e.g. remote-eb.c or sparc-xdep.c.
2379 param.h: Now just a shell that includes tm.h and param-no-tm.h.
2381 remote-vx.c: New file, VxWorks remote debugging support. Uses
2382 RPC routines that are shared with the target system, in directory
2385 remote.c: Vectorize remote interface.
2387 source.c: Globalize source_path, and make an alias "l" for "list"
2388 since we now have the "load" command.
2390 sparc-xdep.c: Use new param-no-tm.h.
2392 symmisc.c (free_named_symtab): Add new function from Wind River.
2393 However, ifdef it out for now while we think about what it should
2396 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
2398 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
2399 non-Unix-children handle this with their own code in the target
2402 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
2403 source and target lists. Add vx-share to default list of include
2404 directories. Add new files to src and target lists: mem-break,
2405 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
2406 ${srcdir} versions of munch and createtags are used.
2408 * valops.c (find_function_addr): Split out of call_function.
2409 (call_function_by_hand): Rename call_function; this function
2410 calls functions in the target by laboriously patching the target
2411 word-by-word with the right stack, args, regs, etc.
2414 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
2416 Handle AMD 29000 a bit better.
2418 * remote-eb.c (readchar): Mask received char log to make it readable.
2419 (remote_start): Pass arguments down to executing program.
2420 Make startaddr unsigned.
2421 infrun.c (start_inferior): Accept args, pass them to
2423 infcmd.c (run_command): Pass args down to start_inferior.
2425 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
2426 the target object file format.
2427 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
2429 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
2430 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
2432 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
2434 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
2435 * TODO: We did a few things, we have more to do though.
2437 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define.
2438 * inflow.c (inferior_died): Clear deferred stores.
2440 * Debug problems with dummy frames and calls to the inferior.
2441 * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME): Move to sparc-tdep.c.
2442 * sparc-tdep.c (do_restore_insn): Simplify.
2443 (sparc_frame_find_saved_regs): Simplify and fix what we find.
2444 (sparc_push_dummy_frame): Simplify and fix what we push.
2445 (sparc_pop_frame): Slightly more hair here, deciding whether
2446 we are restoring a saved PC or returning to a return address in %i7.
2447 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
2449 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
2450 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
2451 * obstack.h (chunkfun): ditto.
2452 * defs.h (xmalloc, xrealloc): ditto
2454 * utils.c (quit): Grab the terminal from the child if necessary.
2456 * inflow.c (term_status_command): Rename to term_info, change
2459 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
2460 (is_delayed_branch): Speed up.
2461 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
2462 Still missing some float ops, and needs testing.
2464 * Support for input and output radixes other than base 10
2465 * defs.h (input_radix, output_radix): Declare.
2466 * expread.y (yyparse, parse_number): Handle changes of input
2467 radix, and ambiguous names-or-numbers in radixes >10.
2468 * printcmd.c (print_scalar_formatted): Print formatted hex
2469 numbers in varying column widths.
2470 * valprint.c (val_print): Use output_format to print scalar ints.
2471 (set_input_radix, set_output_radix, set_radix): Create.
2472 (set_output_radix): Set output_format from output_radix.
2473 (_initialize_valprint): add `set radix' but leave the others off.
2475 * main.c (execute_command): Let stupid questions be turned off.
2476 (_initialize_main): Handle "set stupidity", etc.
2478 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
2479 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
2481 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
2483 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
2484 bfd stuff is still screwed up, but with some manual work, it
2487 * breakpoint.c (bpstat_do_actions): Start over if a command
2488 proceeds the inferior, since the inferior will have stopped and
2489 will need to have its new stop-actions taken care of.
2491 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
2492 compiler fits, simplify it.
2494 * gdb.texinfo (directory command): Doc new dir command.
2495 source.c (directory_command): "dir" now puts things on the front
2496 of the path, moves dups up front, and handles multiple names
2497 on the command line, inserting each one in order. It also
2498 blows away cached line and full_filename info.
2500 * stack.c (backtrace_command): Skip "more stack frames follow"
2503 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
2504 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
2505 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
2506 The only odd one was Gould NP1, which had defined vprintf to
2510 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
2511 variable, inspect_it.
2512 valprint.c (print_string, val_print): Use the global inspect_it
2513 to indicate whether to print in Epoch style or normal style.
2515 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
2517 * printcmd.c (call_command): add an alias for the "print" command
2518 which runs expressions and doesn't print the result if void.
2519 (print_command_1): implement it.
2521 * command.c: Remove #if 0'd code. Initialize all the fields
2522 in add_cmd (). Rename do_nothing_command to
2523 not_just_help_class_command, and make it externally visible.
2524 command.h: add user_commands to struct.
2525 * main.c (define_command): Don't overload c->function with a char
2526 string as well as a function pointer.
2528 * eval.c (evaluate_subexp): Reinstall tiemann changes to
2529 calling convention of value_struct_elt () that got dropped in
2532 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
2533 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
2535 * tm-sparc.h (POP_FRAME): replace some constants with defines.
2537 * sparc-xdep.c (store_inferior_registers): defer stores to regs
2538 until a good time (e.g. when we are about to run the child),
2539 saving ptrace calls.
2540 * infrun.c (proceed): handle DO_DEFERRED_STORES.
2541 * tm-sparc.h: define DO_DEFERRED_STORES.
2543 * sparc-xdep.c (store_inferior_registers): when storing float
2544 registers, don't store stack regs too. When storing the SP,
2545 however, DO store the stack regs too. This fixes a bug in which
2546 the dummy frame is not recognized when a call_function finishes,
2547 because its frame pointer (in the stack regs) was never
2549 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
2550 even though we don't know how to read them from an inferior.
2551 valops.c (call_function): Comment about storing SP.
2553 * infrun.c (save_inferior_status): Save away the original bpstat
2554 chain so it can be restored later. Install the copied version for
2555 use by whoever saved the status. It will be blow away by
2556 restore_inferior_status, and the original chain restored. This is
2557 important for people who have pointers into the original.
2559 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
2560 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
2561 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
2564 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
2566 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
2567 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
2568 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
2570 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
2572 * Merge Mike Tiemann's multiple inheritance changes from Sun.
2573 Store the baseclasses in a type struct starting from array element
2574 0 rather than from the unusual array element 1.
2576 dbxread.c: the above.
2577 (virtual_context): Add
2578 Read new debug information about which virtual function table
2579 a virtual function is from, and store it in fn_field.fcontext.
2581 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
2582 TYPE_FN_FIELD_STATIC_P.
2584 symtab.c: the above.
2585 valops.c: the above. Handle pointer casts of object *'s.
2586 (search_struct_method): Add.
2587 (value_struct_elt): First arg is now a pointer to a value, and is
2590 valprint.c: the above.
2591 values.c (value_virtual_fn_field): Add type arg. Handle
2592 offsetting to the proper object when calling virtual fns.
2594 (baseclass_addr): Add valuep arg.
2596 * README: Document the current state of BFD config (missing).
2597 * TODO, ChangeLog, Makefile.dist: Roll version.
2598 * WHATS.NEW: Add summary of changes since 3.5.
2600 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
2602 * dbxread.c (read_struct_type): Clear bit vectors whenever
2604 symtab.c (B_CLRALL): define.
2606 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
2607 using == rather than =. Huh... This fixes the dreaded problem
2608 wherein builtin_type_int becomes TYPE_CODE_FLT.
2610 * core.c (info_files): Show the inferior pid.
2612 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
2613 already knows how to look in the source directory.
2615 * Remove psymtab hair from many places. Remove duplicated code
2616 for searching symbol tables. Hide psymtabs from most places.
2617 Make it fast to get from a psymtab to its symtab.
2619 blockframe.c (blockvector_for_pc): Remove psymtab hair.
2620 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
2621 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
2622 dbxread.c: export psymtab_to_symtab, make it work if called N times.
2623 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
2624 new symtab completely. New psymtabs get symtab pointer
2625 initialized to zero. Remove MI warning printf.
2626 symtab.h: Comments. Add psymtab to symtab pointer.
2627 (PSYMTAB_TO_SYMTAB): New macro.
2628 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
2629 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
2631 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
2633 (print_frame_info): Avoid special-casing symbols that have not yet
2636 * source.c (open_source_file): Quick path if we have already
2637 located the source file by its full name.
2639 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
2640 find_pc_psymtab. When a name is found in the misc function
2641 vector, search the symbol table for its mangled name, not the
2642 name that the user typed.
2644 * bfd.h: Fix missing comment terminators, make #endifs match.
2646 * valarith.c (value_less): Handle unsigned int comparisons.
2647 Add FIXME about pointer compares, which assume host and target
2648 pointers are the same.
2650 * command.c (do_nothing_command): lint
2651 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
2652 fix comments on debug symbol format for visibility. Actually set
2653 visibility of symbols.
2654 main.c (echo_command): lint; use <readline/history.h>.
2655 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
2656 obstack.h (_obstack_blank): Rearrange pointer math to avoid
2657 pointing past end of allocated memory; saber complains.
2658 obstack.h: Declare the external functions that we use.
2659 valarith.h: use <string.h>
2660 solib.c (solib_add): lint.
2662 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
2664 * main.c (initialize_main): Default info_verbose to off, now that
2665 symbol reading is fast.
2666 (quit_command): Avoid clobbering exec_bfd while quitting.
2668 * Initial BFD (binary file diddling library) merger:
2669 coffread.c: Change AOUTHDR to struct exe_hdr.
2671 core.c: initialize initialized data at compile time.
2672 (core_file_command): Move from coredep.c, convert to bfd.
2673 (xfer_core_file): Convert to bfd.
2674 exec.c (exec_file_command): use bfd routines.
2676 mips-tdep.c: Remove exec_file_command and friends.
2679 * coredep.c: (fetch_core_registers) Convert core_file_command to
2680 fetch_core_registers.
2681 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
2683 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
2684 (my_bfd_read): More bogosity, which I don't think we call.
2685 (program_name): Remove this atrocity asap!
2687 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
2690 values.c: allocate_repeat_value was not clearing the
2691 optimized_out field.
2692 (value_static_field): minor stylistic fix (wrong macro was used).
2693 valops.c (value_struct_elt_for_address): didn't work for C++
2696 * signame.c (_initialize_signame): Initialize signal names once.
2698 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
2699 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
2700 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
2702 * remote-eb.c: Support user-settable baud rates on the serial port.
2704 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
2706 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
2708 * tconfig/sun3os4: Remove warning about native assembler,
2709 since it also occurs in the xconfig file.
2711 * findvar.c (registers): Allocate some slop after `registers'
2712 to prevent stray accesses from trashing the next variable.
2714 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
2715 on the sun-3, by changing the #ifdef from `sun3' (which is not
2716 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
2717 vars, which happened to follow `registers' in the executable.
2719 * readline/history.c (history_search): Heed gcc-2's advice
2720 and parenthesize && inside ||).
2722 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
2723 tm-29k.c: Insert FSF copyright headers.
2725 * remote-eb.c: Better comments.
2727 * Makefile.dist: Update to 3.91.6.
2728 * TODO: note PREPARE_TO_STORE problem.
2730 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
2732 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
2734 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
2736 * infrun.c (wait_for_inferior, at end): Don't set up
2737 prev_* if the inferior no longer exists.
2739 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
2740 CANNOT_EXECUTE_STACK.
2741 valops.c (call_function): Use it.
2743 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
2745 * inferior.h (PC_IN_CALL_DUMMY): New macro.
2746 infrun.c (wait_for_inferior, 2 places): Use it.
2748 * values.c (value_being_returned): Only use
2749 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
2751 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
2752 right thing for remote-eb.c.
2754 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
2755 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
2757 * blockframe.c: Put get_frame_saved_regs inside #if !defined
2758 (FRAME_FIND_SAVED_REGS).
2760 * findvar.c ({fetch,store}_registers): Check for
2761 REMOTE_{FETCH_STORE}_REGISTER macro.
2763 * findvar.c (get_saved_register): Add argument lval and
2764 change meaning of argument addr.
2765 findvar.c: Change calls to get_saved_register to reflect
2766 new calling convention.
2767 valops.c (value_assign): Use get_saved_register instead of
2768 find_saved_register.
2770 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
2772 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
2773 an (uninitialized) pointer to one. Use "&" when passing it
2776 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
2778 * coffread.c (getfilename): Use DGUX x_offset and x_name if
2781 * coffread.c (symbol_file_command): Put semicolon after
2783 Put safe_to_init_tdesc_context in #if defined (TDESC).
2784 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
2785 coffread.c: #include <sys/stat.h>.
2786 (read_coff_symtab): Typo: in_source_files -> in_source_file.
2787 Add missing ')' in check for "lc%" and friends. Remove
2789 Declare read_one_sym() at top of file.
2790 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
2791 MC68WRMAGIC can have the same value without causing a duplicate
2794 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
2796 * Allow a Makefile to be built without building the
2797 tm and xm file links that screw up builds in subdirectories.
2798 This is done with `config.gdb none', then you can do things
2799 like `make gdb.tar.Z'.
2800 * tconfig/none: Config file for no target system
2801 * xconfig/none: Config file for no host system
2802 * config.gdb: If no TM or XM files are called out by the
2803 host or target file, don't make links for them.
2805 * cplus-dem.c: Add documentation.
2807 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
2808 simple error, so the user's gdb doesn't crash due to some object
2809 file problem (e.g. somebody is rebuilding the file out from under
2812 * printcmd.c (print_address_symbolic): demangle the symbol.
2814 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
2815 Motorola copyrights in it. Make "make gdb.tar.Z" work.
2816 (alldeps.mak): sort and uniq all results from this; duplicates
2817 hose gdb.tar.Z link building. Remove RCS files from
2818 tconfig and xconfig. Add config files for sun386. Add
2819 a few odd files to OTHERS and HFILES.
2821 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
2823 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
2824 Roll version number to 3.91.5. Make lint work in bindir.
2826 * README: Document cross-debugging and new file structure.
2828 * blockframe.c: Lint. Include "value.h" to declare read_register.
2829 (find_pc_partial_function): remove duplicate line.
2831 * command.h: Lint. Declare error_no_arg and dont_repeat.
2833 * tm-news.h: Remove inadvertently duplicated stuff.
2835 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
2836 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
2838 * config.gdb: Allow `config.gdb host target' form. Clean
2839 up previous change that printed bogus messages when you just said
2842 * core.c: #include "command.h" for lint.
2845 * main.c: Remove some casts of enums. Lint.
2852 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
2854 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
2855 read it from memory. This will allow us to save ptrace calls
2856 eventually. Changed caller single_step too.
2858 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
2859 that we aren't going to use, saving many ptrace calls, especially
2860 when watchpointing or single stepping. Use some #define's for
2862 (store_inferior_registers): Ditto.
2863 (core_file_command): Use some #define's for constants.
2865 * tm-sparc.h: Add #define's for some register numbers, so we
2866 can eliminate the use of random constants in sparc-xdep.c.
2868 * stack.c (frame_command, print_frame_info, up_command,
2869 down_command) Remove frame_changed, since it
2870 causes a bug and doesn't seem to do anything useful. In some
2871 places it was used as a flag, in others as a stack level (?).
2873 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
2874 default is to use the portable (vprintf) version rather than the
2876 * xm-news.h (MISSING_VPRINTF): Add.
2878 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
2880 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
2882 * Remove stuff that forces -Bstatic linking of gdb, and warnings
2883 about linking debugged programs -Bstatic in the sun?os4 config
2884 files in tconfig and xconfig subdirectories.
2886 * main.c (main): Remove unreached exit(0) now that we exit
2889 * Create TODO file for online bug list. There are too many
2890 "little" bugs to keep track of on paper.
2893 rather than kingdon@ai.
2895 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
2897 * Makefile.dist (VERSION): 3.91.4 now.
2899 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
2900 (condense_misc_bunches): Add sanity check that misc_count is
2901 the same as the number of symbols in the bunch.
2903 * coffread.c: rename init_misc_bunches. Pass an argument
2904 to condense_misc_bunches (a zero).
2906 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
2907 every time we are called; don't rely on our caller to do it.
2908 (add_file): Remove call to init_misc_bunches.
2910 * mipsread.c: Only warn, don't error, if unknown symbol types.
2911 This keeps an old gdb from falling on its face if it sees newly
2912 extended symbol info. Rename init_misc_bunches.
2914 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
2916 * Merge in changes from Per Bothner for DECstations and other
2917 MIPS stuff. The rest is Bothner speaking:
2919 The next message is a merger of Alessando Forin's mips port with
2920 mine. I've tried to use my good if biased judgment to get
2921 the best of both. It *does* need testing.
2923 Some of the changes are general, *not* mips-specific.
2926 Didn't believe in little-endian bit order.
2927 There are still inconsistencies about whether flags
2928 like BITS_BIG_ENDIAN are integer (#if ...) or
2929 boolean (#ifdef ...). I tried to paper over them.
2931 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
2932 Moved some misc_function code that was common to
2933 {dbx,coff,mips}read.c to symtab.c.
2934 In the process, I think I cleaned things up a bit.
2935 At the same time, moved obsavestring and obconcat to symtab.c.
2938 Removed obsolete condense_addl_misc_bunches (use
2939 condense_misc_bunches(1) instead).
2942 Needed to include <sys/dir>, at least on DECstations.
2944 valops.c, mips-tdep.c, tm-mips.h:
2945 Added PUSH_ARGUMENTS macro to support funny argument-pushing
2946 conventions (when STACK_ALIGN is insufficient).
2947 Needed on mips, where doubles need 8-byte alignment,
2948 but ints only need 4.
2951 Removed cruft that was not being used.
2955 Print $ before register-names (I think that makes things a little
2957 Never print two instructions, even if one delays.
2958 Removed hex-disassemble set_cmd. (This is not mips-specific,
2959 so I think the argument is whether it is generally worthwhile or not.
2960 I'm inclined to think not, given how easy it is to
2961 convert between radixes in gdb.)
2964 This is basically Alessando's code.
2965 It doesn't use obstacks; I changed it to use obstacks
2966 in a few minor places where using malloc causes a
2967 memory leak. (Probably, more places could/should be changed.)
2968 I added record_misc_function where it was missing.
2969 In symbol_file_command and add_file_command, I tried
2970 to make the code consistent with more recent versions.
2971 Minor sylistic changes in parse_procedure.
2972 Make a .gdbinfo. psuedo-symbol point back to the real
2973 procedure symbol (using the isym field).
2976 This is basically from my port, but with a lot of details
2977 and a number of routines merged in from Alessando's version.
2978 I basically used my code "raw" backtrace (use heuristics
2979 from the actual code, rather than symbol table info) - though
2980 the idea is Alessandro's. I feel my code is a little cleaner
2981 here, particularly in being a little more flexible, such as being
2982 able to handle gcc-produced code (which it now can).
2983 It also doesn't do frame caching (which is not useful
2984 more recent gdb versions).
2985 I also used my code for push_/pop_dummy, more or less.
2986 I tried to incorporate AF's code for testing sigtramp
2987 while backtracing; I probably got it wrong.
2988 Added mips_print_register, which tries to scrunch as much
2989 information as possible on a screen...
2990 Removed the skip-prologue set_cmd. As with hex-disassemble (see
2991 under mips-pinsn.c), I don't see anything mips-specific here,
2992 and I don't see it being all that useful anyway.
2995 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
2996 Use more register names (rather than hard-cases numbers).
2998 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
3000 * Hack up 3.90.11 changes:
3002 * Makefile.dist (depend): parameterize $(GCC).
3003 Add solib.c and solib.o.
3004 (readline): Fix vpath for both absolute or relative SRCDIR.
3007 Also, let the part I didn't understand at least compile so
3008 I can test the rest. FIXME.
3010 * dbxread.c: Fix thinko using strcmp.
3011 (init_psymbol_list): declare static.
3012 (partial_symbol_file_open): Comment cleanups better, avoid
3013 cleaning up the string table since the caller will do that.
3014 Move the stat for mod time into symbol_file_command, temporarily.
3015 (There should be a mod time for each symbol file, eventually,
3016 to control its rereading. FIXME.)
3018 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
3019 SunOS, which gives error for shared libs otherwise. (From
3020 Schaefer, probably FIXME needs work for portability.)
3022 * solib.c: Move #include "param.h" to work.
3023 Lowercase all the Uppercase Letters In the Messages.
3024 (find_solib): Clean up inferior_so_name for debug printouts.
3025 Allow no argument, to mean all shared libraries.
3027 * symmisc.c: include param.h to get CLEAR_SOLIB.
3029 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
3031 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
3032 to 3.90.11. ChangeLog entries below are from this.
3034 Wed Jun 13 09:17:39 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
3038 * Makefile.dist (HFILES): Add tm-sunos.h.
3040 Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3044 * Makefile.dist (gdb.tar.Z): Change linking of config so it works.
3048 * sparc-opcode.h Added single-operand version of rett.
3050 Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3052 * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
3053 Put parens around gcc_p in expansion.
3055 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
3057 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
3059 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3061 * Changes for Sun shared libraries:
3062 blockframe.c (find_pc_partial_function): If a non-text symbol
3063 is found, set *address = pc - FUNCTION_START_OFFSET.
3064 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
3065 Disable breakpoints instead of giving an error.
3066 source.c (select_source_symtab): Initialize cs_pst.
3067 symmisc.c: Call CLEAR_SOLIB if defined.
3068 symtab.h: Make text{low,high} CORE_ADDR not int.
3069 (psymtab): New field addr.
3071 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
3072 (record_misc_function): Give correct type for N_DATA symbols.
3073 (condense_misc_bunches): do "misc_function_count = j" regardless
3075 Take code which is shared between symbol_file_command and
3076 add_file_command and put it into partial_symbol_file_{open,read}.
3077 Split add_file_command into add_file_command and add_file.
3078 Make psymtab_to_symtab read in the string table if the file
3080 Two new parameters to read_dbx_symtab and start_psymtab.
3081 tm-sunos.h: New file.
3083 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3085 * infcmd.c: Change cont_command to continue_command and "cont"
3088 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3090 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
3092 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
3094 * values.c (USE_STRUCT_CONVENTION): Check for structures of
3095 size 1,2,4,8 rather than size < 8.
3097 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
3098 as necessary, not just once.
3100 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
3102 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3104 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
3106 * tm-news.h: Add CALL_DUMMY_*.
3108 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
3110 * config.gdb: In list_host, list_target, use ${i}, not $i.
3112 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3114 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
3116 * sparc-opcode.h: Change all store floating-point state register
3117 instructions to have the right match & lose fields.
3119 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3121 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
3123 config.gdb: If srcdir != ., create readline directory and
3124 copy a makefile into it.
3126 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
3127 consistency with POSIX.
3129 * breakpoint.c (bpstat_stop_status): Disable watchpoint
3130 when we exit its exp_valid_block.
3132 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
3134 * Makefile.dist: Bump version to 3.91.3.
3136 * Clean up handling of breakpoint commands (somewhat).
3137 Prompted by Tiemann bug report "cont 10" doesn't work any more.
3139 inferior.h: Add breakpoint_proceeded to inferior status struct
3140 and globals; save it and restore it.
3141 (clear_breakpoint_commands): Cleanup, remove old #define.
3143 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
3144 (save_inferior_status, restore_inferior_status): handle it also.
3145 (proceed): Remove earlier code that set breakpoint_proceeded.
3146 It is now set only in clear_proceed_status.
3147 (clear_proceed_status): Cleanup, use bpstat_clear rather
3148 than clear_breakpoint_commands. No callers need the stop_bpstat
3149 between clear_proceed_status and proceed.
3151 infcmd.c: Add breakpoint_proceeded definition and comment.
3152 (cont_command, jump_command, signal_command): Move call to
3153 clear_proceed_status right next to call to proceed.
3155 breakpoint.c (bpstat_do_actions): Avoid clobbering our
3156 caller's argument while running down the chain of breakpoints.
3157 Use new variable "breakpoint_proceeded" to determine when
3158 a command that it executes moves the inferior past the
3160 (bpstat_clear): Handle NULL argument.
3161 (bpstat_clear_actions): Avoid useless call to
3162 breakpoint_auto_delete.
3163 (delete_breakpoint): Clean up bpstat's that are pointing to
3164 the deleted breakpoint from the stop_bpstat chain.
3165 (breakpoint_auto_delete): Simplify.
3167 * Clean up handling of EOF, error on stdin, etc. This was
3168 prompted by a network problem that caused gdb to go into an
3169 infinite loop filling up its malloc'd memory.
3171 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
3172 not clear_breakpoints_commands, which is now gone.
3173 (main): If command_loop returns (e.g. from EOF on stdin), do
3174 a quit_command (looping back to command_loop if quit_command
3175 doesn't really quit).
3176 (command_loop): check result from command_line_input and
3177 exit if it returns NULL, rather than passing the NULL to
3179 (gdb_readline): Free malloc'd result space before returning
3182 * utils.c (query): Handle C-d to mean "yes", just as if the
3183 input was not a terminal. Also avoid infinite loop if EOF
3184 occurs in mid-input-line before newline. This allows
3185 query to be used at EOF on stdin with reasonable results.
3187 * infrun.c (proceed): Set breakpoint_proceeded.
3189 * values.c (value_as_long): Avoid infinite recursion for enums.
3190 (_initialize_values): Fix typo in help msg (kingdon).
3192 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
3193 RL_LIB for linking. This allows -lreadline for linking
3194 and nothing for dependencies, once readline is a real library.
3196 * config.gdb: Jim Kingdon: give useful error message if the
3197 host or target type is not recognized.
3199 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
3200 it just defines it. Dumb, but deal with it.
3202 * Jim Kingdon suggests:
3203 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
3205 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
3207 * Makefile.dist (VERSION): Bump version # to 3.91.2.
3209 * Clean up Bothner's changes.
3211 * blockframe.c (clear_pc_function_cache): New function.
3212 * blockframe.c: remake cache_pc_function_* static.
3213 * dbxread.c (symbol_file_command): remove references to
3214 cache_pc_function_* variables.
3215 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
3216 * printcmd.c: Avoid kludging a global variable (addressprint)
3217 to avoid printing the address of a string twice. Instead,
3218 pass the format letter 's' down low enough that it can be seen
3219 to avoid this problem.
3220 (print_formatted): Pass format arg to value_print.
3221 (restore_addressprint): Remove function.
3222 (do_examine): Avoid hacking addressprint, cleanups and such.
3223 (print_frame_args): Add a comment to a Bothner change.
3224 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
3225 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
3226 to wipe out the values cached in blockframe.c.
3227 * symtab.c (find_method): Add comment saying how big you must
3228 allocate to be "big enough". Per being terse again.
3229 * valprint.c (val_print): Handle format letter "s" to print
3230 strings without addresses. Add comment to vtbl printing code
3231 which casts with wild abandon. Rearrange reference-printing
3233 @0xaddr: value (print w/addressprint)
3234 value (print w/~addressprint)
3235 @0xaddr (parameter lists w/addressprint)
3236 or nothing (parameter lists w/o addressprint)
3238 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
3240 * Merge more changes from Per Bothner:
3242 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
3243 annoying) that I tried to improve it. Here are my suggestions.
3245 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
3248 Do automatic de-reference when taking the address of a reference.
3250 Don't deref_ref when printing parameter lists.
3252 More attempts at treating refernences properly.
3254 In val_print, if deref_ref==0, don't print dangling " = ".
3256 Add COERCE_REF macro, which de-references an REF.
3258 * Merge changes from Per Bothner:
3260 * Fixed (Sony news)-specific configuration problems.
3261 * Fixed other problems with using vanilla pcc and libc (enum problems;
3262 assumption that vsprintf exists).
3263 * Some major speed-ups (finc_pc_partial_function now caches a match;
3264 parsing avoids duplicate symbol_lookup calls).
3265 * Changed handling of baseclasses (no longer use baseclasses field
3266 of struct type, use the first n_baseclasses fields instead).
3267 * Various minor changes/fixes, most C++-related.
3270 Cache the most previous match from find_pc_partial_function.
3271 (Save both low and high ends of matching function's pc range.)
3272 This speeds up the loop of infrun.c:wait_for_inferior quite
3273 a bit, and makes step/next commands much zippier.
3275 Added an enum->int cast (otherwise, some compilers barf).
3277 No longer set baseclass offset to 0, since multiple
3278 inheritance now mostly works.
3279 Added a number of casts, to shut up compiler warnings
3280 (after stabs where made enums, not ints).
3281 When discarding a symbol table (in symbol_file_command),
3282 must clear the cache introduced in blockframe.c.
3283 Don't convert $vtbl_ptr_type to vtbl any more.
3284 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
3285 Mask off sign bit emitted by g++ for virtual table offset.
3286 Set voffset to -1 (not 1) for static member functions.
3288 Changed parsing/lexing of names to avoid doing symbol lookup twice
3289 (once when lexing to determine symbol class, once for real).
3290 Now only call symbol_lookup once. Fields of 'this' win especially big.
3292 Subpress printing addr twice in the case of 'x/s addr'.
3294 lookup_basetype_type is no longer used.
3295 Add find_methods as recursive helper function to decode_line_1.
3296 This allows multiple inheritance to work.
3297 Also, once one or more matches has been found, do not look in
3298 base-classes. (Baseclass methods would be overridden, anyway.)
3300 Removed baseclasses array in struct type.
3301 Instead of using baseclasses[i], use fields[i-1].
3302 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
3303 Changed sign convention of voffset (previous was inconsistent).
3305 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
3307 Used to assume existence of vsprintf. Re-written to not need it
3308 if HAVE_VPRINTF is undefined.
3310 typecmp was too pessimistic. Made it less so.
3312 Don't print space after address.
3313 If vtable points to a misc symbol (with 0 offset), print it,
3314 since that indicates the actual class of the object.
3315 Changed ype_print_derivation_info to use new inheritance
3316 scheme (without baseclasses vector).
3318 In value_primitive_field, fixed some bugs left over from previous set of fixes.
3319 Also, changes needed because TYPE_BASECLASSES were removed.
3321 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
3323 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
3326 If there is no path set, and the symbols don't indicate what directory
3327 a file was compiled in, look in the current directory. But either
3328 a path or a known compilation directory will prevent this.
3331 Three independent bug fixes:
3332 * Remove the #if 0 block that breaks some stuff.
3333 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
3334 adapt gdb to either SunOS 4.0.* or 4.1.
3335 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
3338 Instantiate the class T when looking for methods in it. (Tiemann@sun)
3341 (type_print) Demangle the name being printed.
3342 (type_print_base) Handle botched demangling without coredump (tiemann).
3345 (check_stub_method): Document routine.
3346 (tiemann) fix bug for no-arg functions
3347 Avoid clobbering beyond end of malloc'd storage.
3348 Terminate the argument list properly.
3352 * Changes merged by John Gilmore:
3355 In breakpoint_1, use new print_address_symbolic instead
3356 of find_pc_partial_function. (This forces use of assembler-level
3357 addresses, and avoids misleading non-mangled source-level names.)
3359 Generalize ansi argument such that -1 means skip arglist totally.
3360 Removed global variable print_ansi_qualifiers (which made
3361 code non-reentrant), in favor of extra explicit arguments
3362 to internal routines.
3364 Add new helper function print_address_symbolic.
3365 Use find_pc_misc_function instead of find_pc_partial_function
3366 (since we want assembler-level symbols here).
3368 Print unknown function as just "f (...)", not "f (...) (...)".
3369 Use new fputs_demangled explicitly.
3371 Fixed a typing violation (problem: value.h cannot be imported
3372 without renaming many variable in this file).
3373 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
3374 decode_line_1: Moved forward some never-reached code.
3375 Made decode_line_2 skip function prologues correctly.
3377 fputs_filtered should not demangle by default.
3378 Add new fputs_demangled to demangle on demand..
3380 Change value_struct_elt to use value_primitive_field (using recursive
3381 utility function search_struct_field). This allows foo.bar to work
3382 for multiple inheritance (so far only for data fields).
3383 Change check_field in the same way (recursive helper function
3384 to support multiple inheritance).
3385 (Note: there are more of these problems that I haven't fixed.
3386 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
3387 value_of_this: 'this' symbol name is now just "this", note "$this".
3389 Don't print static members.
3390 Avoid printing "members of <type>" if there are none.
3391 Simplified type_print_derivation_info by merging duplicate code.
3392 Remove useless blank lines in type_print_base (ptype command).
3394 Added declaration of new routine value_primitive_field.
3396 Added value_primitive_field which is generalized version of
3397 value_field that can handle multiple inheritance (non-zero offsets etc).
3398 Re-implemented value_field to call value_primitive_field.
3400 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
3402 * infcmd.c -- insert else to avoid 'delete env' coredump when you
3403 delete the whole environment. Karl Berry reported the bug.
3404 * source.c - fix openp to avoid //'s in filenames, which
3405 trigger an Emacs bug causing it to not be able to find files
3406 when running gdb in a window.
3407 * dbxread.c - zap the #if 0 that botches the add-file code.
3408 It seems to work a lot better without all the code commented out.
3410 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
3412 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
3415 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
3417 * Makefile - added a ${CFLAGS} to a couple of entries,
3418 added remote-sa.sparc.c
3419 * added remote.sa-sparc.c, a modification of remote.c
3420 which conducts a dialog directly with the SparcStation prom.
3421 * breakpoint.c, infrun.c, sparcdep.c added
3422 remote_insert_breakpoint(), and remote_remove_breakpoint()
3423 to breakpoint.c instead of directly writing breakpoint instructions.
3424 * sparcdep.c on remote_debugging,there is no need
3425 to remove signle step breakpoint instructions.
3426 * main.c added "-epoch" flag and "int epoch_interface" to main.c
3428 * printcmd.c - epoch interface sends lisp expressions to open up
3429 epoch windows on inspection.
3430 * valprint.c - added arrayprint, and addressprint and made adding
3431 format controls easier
3432 * wait.h added a couple of undef's because we were getting
3433 complaints about WSTOPSIG and WTERMSIG begin redefined.
3436 Wed Jul 4 05:27:51 1990 Michael Tiemann (tiemann at masham)
3438 * symtab.c (decode_line_1): Add support for handling method stubs
3439 in the type information.
3441 Tue Jul 3 09:39:18 1990 Michael Tiemann (tiemann at masham)
3443 * values.c (baseclass_addr): Run loop from INDEX+1 to
3444 N_BASECLASSES; otherwise, we can still get into a loop.
3445 @@ This should be restructured to use a cleaner search strategy.
3447 Sun Jul 1 12:28:51 1990 Michael Tiemann (tiemann at masham)
3449 * dbxread.c (define_symbol,read_type): Grok GNU C++'s new
3450 abbreviation "Tt" for tags which have the same name as their
3453 Fri Jun 29 01:03:46 1990 Michael Tiemann (tiemann at masham)
3455 * symtab.c (list_symbols): add ability to set breakpoints on all
3456 the functions which match a particular regular expression.
3458 Tue Jun 26 04:26:29 1990 Michael Tiemann (tiemann at masham)
3460 * cplus-dem.c (cplus_demangle): New parameter ANSI says whether we
3461 should print ANSI qualifiers (such as `const' and `volatile').
3462 All callers changed to call with ANSI == 1, except from
3463 `check_method_stub', which uses old-style syntax.
3465 * symseg.h (struct fn_field): Remove unneccessary `args' field.
3466 * symtab.h (TYPE_FN_FIELD_ARGS): Redefined.
3468 * values.c (check_stub_method): New function.
3470 * cplus-dem.c (do_type): Handle "long long" (encoded as 'x').
3472 * dbxread.c (read_type): Handle new GNU C++ method type stubs.
3473 * valprint (type_print_base): Ditto.
3475 * symtab.c (gdb_mangle_typename): New function.
3477 Tue Jun 5 00:18:43 1990 Michael Tiemann (tiemann at gzilla)
3479 * breakpoint.c (catch_command): New function. Provides a
3480 mechanism to set breakpoints based on catch clauses.
3481 (disable_catch): Similar, but disables breakpoints on catch
3483 (delete_catch): Similar, but deleted breakpoints on catch clauses.
3485 Sun Jun 3 22:54:08 1990 Michael Tiemann (tiemann at gzilla)
3487 * blockframe.c (blockvector_for_pc): New function.
3488 * blockframe.c (block_for_pc): Changed to call
3489 `blockvector_for_pc' and get the block itself.
3491 * stack.c (catch_info): New function. Prints info about
3492 exceptions which can be caught in the current frame.
3493 * stack.c (print_frame_label_vars): New function. Similar to
3494 `print_frame_local_vars'.
3495 * stack.c (print_block_frame_labels): Prints out labels that are
3496 defined in this frame. These labels are exceptions that can be
3499 * dbxread.c: Updated to handle N_CATCH symtab types.
3501 Thu May 3 22:10:00 1990 Michael Tiemann (tiemann at teacake)
3503 * valprint.c (everywhere): TYPE_NAME (TYPE) no longer comes in the
3504 form "struct ..." for GNU C++. Don't flush any part of TYPE_NAME
3505 when printing the type.
3507 Wed May 2 22:43:04 1990 Michael Tiemann (tiemann at teacake)
3509 * valprint.c (val_print): Use `baseclass_addr' to access the
3510 baseclasses pointed to via the derived class object at VALADDR.
3512 * values.c (baseclass_addr): New function. Casts derived pointers
3513 to baseclass pointers taking virtual baseclasses and multiple
3514 inheritance into account.
3516 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3520 Fri May 4 12:12:55 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3522 * breakpoint.c (watch_command, bpstat_stop_status): Deal with
3523 exp_valid_block field correctly.
3525 * infrun.c (wait_for_inferior): When checking "don't even think
3526 about breakpoints" if stop_signal == SIGTRAP && trap_expected,
3527 also check step_resume_breakpoint.
3528 Insert breakpoints and continue (not step) if
3529 step_resume_break_address != NULL, even if another_trap.
3530 If trap_expected and we enter sigtramp, then set up a
3532 If trap_expected is set when we hit the step_resume_break,
3534 When calling resume and trap_expected says tell resume to step
3535 (2 places), also check step_resume_break_address.
3537 * infrun.c (wait_for_inferior): Don't set
3538 prev_{pc,sp,func_{start,name}} before calling wait ().
3539 Do set them after exiting loop.
3540 Move their declarations outside functions.
3541 (start_inferior): Initialize them.
3543 Thu May 3 00:15:11 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3545 * infrun.c (wait_for_inferior, after check for trap_expected > 1):
3546 Restore old code which distinguishes between trap_expected and
3547 running_in_shell, just make the latter take any non-TRAP signal,
3550 * values.c (allocate_value): Zero VALUE_OPTIMIZED_OUT flag.
3552 * Makefile.dist (pinsn.o): Use PINSN_CC to compile.
3553 xconfig/3b1 (CC,PINSN_CC): Define.
3555 * xconfig/altos, altos-dep.c: Rename altos-dep.c to altos-xdep.c.

3563 infcmd.c (jump_command, read_pc), infrun.c (wait_for_inferior),
3564 printcmd.c (do_one_display): Use them.
3566 * utils.c: Split #ifdef USG into a USG_UTILS and a QUEUE_MISSING.
3567 xm-88k.h: Define USG_UTILS.

3572 (printf_command): Add from_tty parameter.
3574 * valprint.c (value_print): Check VALUE_OPTIMIZED_OUT flag.
3576 * value.h: Add optimized_out field and change lazy field to
3577 char. Add macro VALUE_OPTIMIZED_OUT.
3579 * i386-pinsn.c: Change from Eirik Fuller to write to stream directly
3580 instead of stuffing things in buffers (oappend, etc).
3582 * breakpoint.c (bpstat_do_actions): If *BSP is set to NULL by
3583 execute_command, exit both loops.
3585 * Makefile.dist: Don't set TARGET_ARCH. Add .c.o rule.
3587 Tue May 1 17:07:23 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
