	The following changes remove the glyph_row `inverse_p' field,
	which is never set anymore, due to other changes:

	* dispextern.h (struct glyph_row): Remove `inverse_p' field.
	(reassert_line_highlight, change_line_highlight): Declarations removed.
	* dispnew.c (update_frame_line): Don't call reassert_line_highlight.
	(line_hash_code, row_equal_p, fake_current_matrices)
	(build_frame_matrix_from_leaf_window, update_frame_line)
	(update_frame_line, update_frame_line, update_frame_line):
	Don't use `inverse_p' field.
	* xterm.c (x_initialize): Don't set reassert_line_highlight_hook or
	(XTreassert_line_highlight, x_change_line_highlight):
	Functions removed.
	(x_fix_overlapping_area, x_write_glyphs, expose_area)
	(expose_line, x_erase_phys_cursor): Don't use `inverse_p' field.
	* xdisp.c (dump_glyph_row, display_mode_line): Don't use
	`inverse_p' field.
	* w32term.c (x_fix_overlapping_area, x_write_glyphs, expose_area)
	(expose_line, x_erase_phys_cursor): Don't use `inverse_p' field.
	(w32_reassert_line_highlight, x_change_line_highlight):
	Functions removed.
	* w32console.c (reassert_line_highlight, change_line_highlight):
	Functions removed.
	(initialize_w32_display): Don't set reassert_line_highlight_hook
	or change_line_highlight_hook.
	(hl_mode): Function removed.
	(reset_terminal_modes, set_terminal_modes, update_begin)

	The following changes remove inverse-video support for terminals
	that use a `magic cookie' standout mode.  Due to changes in the

	(term_init): Don't set them.

2001-10-16  Ken Raeburn  <>

	Avoid the assumption that car and cdr slots of cons cells are
	addressable lvalues; this allows for easier experimentation with
	other lisp implementations that may not permit such accesses for
	various reasons.  Not quite complete -- buffer.c still needs some
	work, and w32/mac files need rechecking -- so compile-time
	enforcement is left disabled for now.

	struct glyph were not set, which made glyphs unequal when compared

2000-03-09  Gerd Moellmann  <>

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

2000-03-08  Stefan Monnier  <>

	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.

	* 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.

	(NUM_REG_ITEMS): Remove.
	(TOP_FAILURE_HANDLE): New macros for the cycle detection.
	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.
	(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)
	(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)
	(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.
