versions of XMARK and friends here, because XMARK and friends won't work on an
integer field if NO_UNION_TYPE is not defined.
(make_number): Define as a function if it's not defined as a macro.
(term_init): Intitialize TN_no_color_video.
(enum no_color_bit): New enumeration.
(MAY_USE_WITH_COLORS_P): New macro.
(turn_on_face): Use it to determine if attributes may be used
combined with colors.
* xdisp.c (compute_string_pos): Fix order of arguments to
string_pos_nchars_ahead.
(handle_fontified_prop, add_to_log): Pass int, not Lisp_Object, as
count arg to variable-arg routines like Frun_hook_with_args and Fformat.
(back_to_previous_visible_line_start, build_desired_tool_bar_string):
Pass Lisp_Object, not int, to fixed-arg routines like
Fget_char_property and Fmake_string.
(reconsider_clip_changes): Use XINT when comparing integer lisp
objects, or passing them as int arguments.
(mark_window_display_accurate, insert_left_trunc_glyphs, append_space,
extend_face_to_end_of_line): Use make_number when storing or passing
integer values as lisp objects.
(set_cursor_from_row, highlight_trailing_whitespace): Use INTEGERP,
not implicit test against zero, for glyph object.
(try_window_id): Don't use make_number when we want an int value.
* xfaces.c (xlfd_symbolic_value): Make last argument a Lisp_Object, to
be consistent with callers.
(Fbitmap_spec_p): Use XINT to get numeric value of height.
(lface_hash): Apply XFASTINT to lisp values before folding in.
* xfns.c (Fx_show_tip): Use make_number to get lisp objects to fill in window
width and height. Pass an int, not a lisp object, as first arg to Finsert.
with int lvalues via casts; instead, just yield lisp object
lvalues.
(enlarge_window): Variable sizep now points to Lisp_Object. Use
proper accessor macros.
(shrink_window_lowest_first): w->top is Lisp_Object; use XINT.
(grow_mini_window): Fix typo getting int value of root->height.
inspection. Beginnings of support for expensive internal consistency checks.
* config.in (ENABLE_CHECKING): Undef.
* lisp.h (struct interval): Replace "parent" field with a union of interval
pointer and Lisp_Object; add new bitfield to use as discriminant. Change other
flag fields to bitfields.
(CHECK): New macro for consistency checking. If ENABLE_CHECKING is defined and
the supplied test fails, print a message and abort.
(eassert): New macro. Use CHECK to provide an assert-like facility.
* intervals.h (NULL_INTERVAL_P): Now applies only to real interval pointers;
abort if the value looks like a lisp object.
(NULL_INTERVAL_P, NULL_PARENT, HAS_PARENT, HAS_OBJECT, SET_PARENT, SET_OBJECT,
INTERVAL_PARENT, GET_INTERVAL_OBJECT, COPY_PARENT): Modify for new interval
parent definition.
* alloc.c (mark_interval_tree, MARK_INTERVAL_TREE, UNMARK_BALANCE_INTERVALS):
Update references that need an addressable lisp object in the interval
structure.
(die): New function.
(suppress_checking): New variable.
* intervals.c (interval_start_pos): Just return 0 if there's no parent object.
of re_compile_fastmap and generalizing it a little bit so that it
can also just return whether a given (sub)pattern can match the empty
string or not.
(regex_compile): Use `analyse_first' to decide whether the loop-check
needs to be done or not for *, +, *? and +? (the loop check is costly
for non-greedy repetition).
(re_compile_fastmap): Delegate the actual work to `analyse_first'.
(enum re_opcode_t): Update description of succeed_n.
(PATFETCH): Always define.
(regex_compile): Use lookahead rather than PATUNFETCH (for repetition
operators, char classes, shy-groups and intervals).
Optimize special cases of intervals so as to only use succeed_n and
jump_n when really needed.
(re_compile_fastmap): Simplify handling of jump_n and succeed_n now
that we don't have to handle the special cases any more.
Simplify on_failure_jump handling as well.
(mark_memory): Use it.
(SETJMP_WILL_LIKELY_WORK, SETJMP_WILL_NOT_WORK): New macros.
(setjmp_tested_p, longjmp_done): New variables.
(test_setjmp): New function.
(mark_stack) [!GC_SETJMP_WORKS]: Call test_setjmp.
(init_alloc): Initialize setjmp_tested_p and longjmp_done.
(PER_BUFFER_VAR_OFFSET): Renamed from BUFFER_LOCAL_VAR_OFFSET.
(PER_BUFFER_VAR_IDX): Renamed from BUFFER_LOCAL_VAR_IDX.
(PER_BUFFER_VALUE_P): Renamed from BUFFER_HAS_LOCAL_VALUE_P.
(SET_PER_BUFFER_VALUE_P): Renamed from SET_BUFFER_HAS_LOCAL_VALUE_P.
(PER_BUFFER_IDX): Renamed from BUFFER_LOCAL_IDX.
(PER_BUFFER_DEFAULT): Renamed from BUFFER_LOCAL_DEFAULT_VALUE.
(PER_BUFFER_VALUE): Renamed from BUFFER_LOCAL_VALUE.
(PER_BUFFER_SYMBOL): Renamed from BUFFER_LOCAL_SYMBOL.
(PER_BUFFER_TYPE): Renamed from BUFFER_LOCAL_TYPE.
