2000-03-12  Dave Love  <fx@gnu.org>

        * unexelf.c: Restore changes of 1999-10-19.

        (Qbar, Qcursor_type, outside_cursor): New variables.
        (syms_of_msdos): Intern and staticpro them.

        type has changed.
        (IT_set_frame_parameters): Call IT_set_cursor_type if the frame

2000-03-09  Gerd Moellmann  <gerd@gnu.org>

        * fns.c (Fy_or_n_p): Cancel busy-cursor.

2000-03-08  Stefan Monnier  <monnier@cs.yale.edu>

        This is a big redesign of failure-stack and register handling, prompted
        by bugs revealed when trying to add shy-groups.  Overall, what happened
        is that loops are now structured a little differently, groups can be
        shy and the code is a little simpler.

        * regex.h: Update the copyright.
        (RE_SHY_GROUPS): New value.
        (RE_UNMATCHED_RIGHT_PAREN_ORD): Renumber.
        (RE_SYNTAX_EMACS): Add RE_SHY_GROUPS.

        * regex.c (enum re_opcode_t): Remove jump_past_alt,
        maybe_pop_jump, push_dummy_failure and dumy_failure_jump.  Add
        on_failure_jump_(exclusive, loop and smart).  Also fix the comment
        for (start|stop)_memory since they now only take one argument (the
        second has becomes unnecessary).
        (print_partial_compiled_pattern): Adjust for changes in
        re_opcode_t.
        (print_compiled_pattern): Use %ld to printf long ints and flush to
        make debugging a little easier.
        (union fail_stack_elt): Make the integer unsigned.
        (struct fail_stack_type): Add a `frame' element.
        (INIT_FAIL_STACK): Init `frame' as well.
        (POP_PATTERN_OP): New macro for re_compile_fastmap.
        (DEBUG_PUSH, DEBUG_POP): Remove.
        (NUM_REG_ITEMS): Remove.
        (NUM_NONREG_ITEMS): Adjust.
        (FAILURE_PAT, FAILURE_STR, NEXT_FAILURE_HANDLE)
        (TOP_FAILURE_HANDLE): New macros for the cycle detection.
        (ENSURE_FAIL_STACK): New macro for PUSH_FAILURE_(REG|POINT).
        (PUSH_FAILURE_REG, POP_FAILURE_REG, CHECK_INFINITE_LOOP): New
        macros.
        (PUSH_FAILURE_POINT): Don't push registers any more.  The pattern
        address pushed is not the destination of the jump but the source
        of it instead.
        (NUM_FAILURE_ITEMS): Remove.
        (POP_FAILURE_POINT): Adapt to the new stack structure (i.e. pop
        registers before the actual failure point).  Don't hardcode any
        meaning for str==NULL anymore.
        (union register_info_type, REG_MATCH_NULL_STRING_P, IS_ACTIVE)
        (MATCHED_SOMETHING, EVER_MATCHED_SOMETHING, SET_REGS_MATCHED):
        Remove.
        (REG_UNSET_VALUE): Use NULL (why not?).
        (compile_range): Remove declaration since it doesn't exist.
        (struct compile_stack_elt_t): Remove inner_group_offset.
        (old_reg(start|end), reg_info, reg_dummy, reg_info_dummy): Remove.
        (regex_grow_registers): Remove dead code.
        (FIXUP_ALT_JUMP): New macro.
        (regex_compile): Add shy-groups Change loops to use
        on_failure_jump_smart&jump instead of
        on_failure_jump&maybe_pop_jump.  Change + loops to eliminate the
        initial (dummy_failure_)jump.  Remove c1_base (looks like unused
        variable to me).  Use `jump' instead of `jump_past_alt' and don't
        bother with push_dummy_failure in alternatives since it is now
        unnecessary.  Use FIXUP_ALT_JUMP.  Eliminate a useless `#ifdef
        emacs' for (re)allocating the stack.
        (re_compile_fastmap): Remove dead variables i and num_regs.  Exit
        from loop when bufp->can_be_null rather than jumping to `done'.
        Avoid jumping backwards so as to ensure termination.  Use
        PATTERN_STACK_EMPTY and POP_PATTERN_OP.  Improved handling of
        backreferences.  Remove dead code in handling of `anychar'.
        (skip_noops, mutually_exclusive_p): New functions taken from the
        handling of `maybe_pop_jump' in re_match_2_internal.  Slightly
        improve mutually_exclusive_p to handle ".+\n".
        (lowest_active_reg, highest_active_reg,
        NO_(LOWEST|HIGHEST)_ACTIVE_REG) Remove.
        (re_match_2_internal): Use %p instead of 0x%x when printf'ing
        ptrs.  Don't SET_REGS_MATCHED anymore.  Remove many dead
        variables.  Push register (in `start_memory') on the stack rather
        than storing it in old_reg(start|end).  Remove the cycle detection
        from `stop_memory', replaced by the use of on_failure_jump_loop
        for greedy loops.  Add code for the new on_failure_jump_<foo>.
        Remove ad-hoc code in `on_failure_jump' to push more registers in
        the case of a loop.  Take out code from `maybe_pop_jump' into
        separate functions and adapt it to the semantics of
        `on_failure_jump_smart'.  Remove jump_past_alt, dummy_failure_jump
        and push_dummy_failure.  Remove dummy_failure handling and
        handling of `failures to jump to on_failure_jump' (this last one
        was already dead code, it seems).
        (group_match_null_string_p, alt_match_null_string_p)
        (common_op_match_null_string_p): Remove.

2000-03-08  Dave Love  <fx@gnu.org>

        * config.in: Don't depend on __STDC__ for volatile.

        (detect_coding_mask): When priorities are specified, skip any

        wrong mask when PRIORITIES is specified and detect_coding_XXX()
        returns a mask not set in PRIORITIES.
        (detect_eol_type_in_2_octet_form): New function.
        (detect_eol): selects detect_eol_type_XXX to call according to
        cooding->category_idx.
        (detect_coding_system): Remove `nil' coding-system in the result.
        (Fupdate_coding_systems_internal): Update all coding-categories.

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

        * minibuf.c (Fminibuffer_complete): Move point to ZV when input is
        complete but not unique.

2000-03-06  Gerd Moellmann  <gerd@gnu.org>
