504 (x_append_glyph): Set glyph->glyph_not_available_p.
505 (x_produce_glyphs): Set it->glyph_not_available_p. Don't set
506 it->charset. Handle the case that per char metric is not

508 character, convert it to a unibyte character.
509 (struct glyph_string): Delete member `charset'.
510 (x_set_mouse_face_gc): Call FACE_FOR_CHAR to get face_id. Handle
511 the case that per char metric is not available correctly.

530 * buffer.c (Fset_buffer_modified_p): Set update_mode_lines
531 only if buffer is displayed in some window.
533 * xdisp.c (handle_single_display_prop): Initialize local `value'.
534 (try_window_reusing_current_matrix): Don't call scroll run
535 function if run's current and desired position are the same;
536 this prevents cursor flickering.
538 2000-03-19 Stefan Monnier <monnier@cs.yale.edu>
540 * regex.h (RE_TRANSLATE. RE_TRANSLATE_P): Moved to regex.c.

553 (skip_one_char): New function.
554 (skip_noops): Simplify since `memory' is not needed any more.
555 (mutually_exclusive_p): Restructure slightly to use `switch' and
556 add handling for "all" remaining cases.
557 (re_match_2_internal): Change on_failure_jump_smart to use
558 on_failure_keep_string_jump (and redirect the end-of-loop jump)
559 rather than on_failure_jump_exclusive.
561 2000-03-19 Gerd Moellmann <gerd@gnu.org>
563 * xfns.c (select_visual): Don't set dpyinfo->n_planes to the
564 number of bits per RGB because it's everywhere used as the depth
567 * term.c (calculate_costs): Remove code dealing with X frames.
569 2000-03-19 Richard M. Stallman <rms@caffeine.ai.mit.edu>

592 * regex.c (re_match_2): Fix string shortening (to fit `stop') to
593 make sure POINTER_TO_OFFSET gives the same value before and after
594 PREFETCH. Use `dfail' to guarantee "atomic" matching.
595 (PTR_TO_OFFSET): Use POINTER_TO_OFFSET.
596 (debug): Now only active if > 0 rather than if != 0.
597 (DEBUG_*): Update for the new meaning of `debug'.
598 (print_partial_compiled_pattern): Add missing `succeed' case. Use
599 CHARSET_* macros in the charset(_not) branch. Fix off-by-two bugs
600 in `succeed_n', `jump_n' and `set_number_at'.

654 If set, call XSynchronize.
656 2000-03-13 Stefan Monnier <monnier@cs.yale.edu>
658 * regex.c: Declare a new type `re_char' used throughout the code
659 for the string char type. It's `const unsigned char' to match the
660 rest of Emacs. Consistently make sure all pointers to strings use
661 it and make sure all pointers into the pattern use `unsigned
663 (re_match_2_internal): Use `PREFETCH+STRING_CHAR' instead of
664 GET_CHAR_AFTER_2. Also merge wordbound and notwordbound to reduce

674 of them try to use backquotes.
676 2000-03-12 Dave Love <fx@gnu.org>
678 * unexelf.c: Restore changes of 1999-10-19.
679 (unexec): Don't adjust bss for sbss type SHT_PROGBITS; otherwise
680 fix its type and alignment; copy it from current process.
682 2000-03-12 Gerd Moellmann <gerd@gnu.org>

710 variable (renamed to Qreverse).
712 2000-03-09 Gerd Moellmann <gerd@gnu.org>
714 * fns.c (Fy_or_n_p): Cancel busy-cursor.
716 2000-03-08 Stefan Monnier <monnier@cs.yale.edu>
718 This is a big redesign of failure-stack and register handling, prompted
719 by bugs revealed when trying to add shy-groups. Overall, what happened
720 is that loops are now structured a little differently, groups can be
721 shy and the code is a little simpler.
723 * regex.h: Update the copyright.
724 (RE_SHY_GROUPS): New value.
725 (RE_UNMATCHED_RIGHT_PAREN_ORD): Renumber.
726 (RE_SYNTAX_EMACS): Add RE_SHY_GROUPS.
728 * regex.c (enum re_opcode_t): Remove jump_past_alt,
729 maybe_pop_jump, push_dummy_failure and dumy_failure_jump. Add
730 on_failure_jump_(exclusive, loop and smart). Also fix the comment
731 for (start|stop)_memory since they now only take one argument (the
732 second has becomes unnecessary).
733 (print_partial_compiled_pattern): Adjust for changes in
735 (print_compiled_pattern): Use %ld to printf long ints and flush to
736 make debugging a little easier.
737 (union fail_stack_elt): Make the integer unsigned.
738 (struct fail_stack_type): Add a `frame' element.
739 (INIT_FAIL_STACK): Init `frame' as well.
740 (POP_PATTERN_OP): New macro for re_compile_fastmap.
741 (DEBUG_PUSH, DEBUG_POP): Remove.
742 (NUM_REG_ITEMS): Remove.
743 (NUM_NONREG_ITEMS): Adjust.
744 (FAILURE_PAT, FAILURE_STR, NEXT_FAILURE_HANDLE)
745 (TOP_FAILURE_HANDLE): New macros for the cycle detection.
746 (ENSURE_FAIL_STACK): New macro for PUSH_FAILURE_(REG|POINT).
747 (PUSH_FAILURE_REG, POP_FAILURE_REG, CHECK_INFINITE_LOOP): New
749 (PUSH_FAILURE_POINT): Don't push registers any more. The pattern
750 address pushed is not the destination of the jump but the source
752 (NUM_FAILURE_ITEMS): Remove.
753 (POP_FAILURE_POINT): Adapt to the new stack structure (i.e. pop
754 registers before the actual failure point). Don't hardcode any
755 meaning for str==NULL anymore.
756 (union register_info_type, REG_MATCH_NULL_STRING_P, IS_ACTIVE)
757 (MATCHED_SOMETHING, EVER_MATCHED_SOMETHING, SET_REGS_MATCHED):
759 (REG_UNSET_VALUE): Use NULL (why not?).
760 (compile_range): Remove declaration since it doesn't exist.
761 (struct compile_stack_elt_t): Remove inner_group_offset.
762 (old_reg(start|end), reg_info, reg_dummy, reg_info_dummy): Remove.
763 (regex_grow_registers): Remove dead code.
764 (FIXUP_ALT_JUMP): New macro.
765 (regex_compile): Add shy-groups Change loops to use
766 on_failure_jump_smart&jump instead of
767 on_failure_jump&maybe_pop_jump. Change + loops to eliminate the
768 initial (dummy_failure_)jump. Remove c1_base (looks like unused
769 variable to me). Use `jump' instead of `jump_past_alt' and don't
770 bother with push_dummy_failure in alternatives since it is now
771 unnecessary. Use FIXUP_ALT_JUMP. Eliminate a useless `#ifdef
772 emacs' for (re)allocating the stack.
773 (re_compile_fastmap): Remove dead variables i and num_regs. Exit
774 from loop when bufp->can_be_null rather than jumping to `done'.
775 Avoid jumping backwards so as to ensure termination. Use
776 PATTERN_STACK_EMPTY and POP_PATTERN_OP. Improved handling of
777 backreferences. Remove dead code in handling of `anychar'.
778 (skip_noops, mutually_exclusive_p): New functions taken from the
779 handling of `maybe_pop_jump' in re_match_2_internal. Slightly
780 improve mutually_exclusive_p to handle ".+\n".
781 (lowest_active_reg, highest_active_reg,
782 NO_(LOWEST|HIGHEST)_ACTIVE_REG) Remove.
783 (re_match_2_internal): Use %p instead of 0x%x when printf'ing
784 ptrs. Don't SET_REGS_MATCHED anymore. Remove many dead
785 variables. Push register (in `start_memory') on the stack rather
786 than storing it in old_reg(start|end). Remove the cycle detection
787 from `stop_memory', replaced by the use of on_failure_jump_loop
788 for greedy loops. Add code for the new on_failure_jump_<foo>.
789 Remove ad-hoc code in `on_failure_jump' to push more registers in
790 the case of a loop. Take out code from `maybe_pop_jump' into
791 separate functions and adapt it to the semantics of
792 `on_failure_jump_smart'. Remove jump_past_alt, dummy_failure_jump
793 and push_dummy_failure. Remove dummy_failure handling and
794 handling of `failures to jump to on_failure_jump' (this last one
795 was already dead code, it seems).
796 (group_match_null_string_p, alt_match_null_string_p)
797 (common_op_match_null_string_p): Remove.
799 2000-03-08 Dave Love <fx@gnu.org>

833 (detect_coding_mask): When priorities are specified, skip any
834 categories that have `nil' coding-system. Fix bug of returning

836 returns a mask not set in PRIORITIES.
837 (detect_eol_type_in_2_octet_form): New function.
838 (detect_eol): selects detect_eol_type_XXX to call according to

859 * xterm.c (x_connection_closed) [USE_X_TOOLKIT]: Don't try to
860 close the display with XtCloseDisplay. This caused a bus error
