extract gap array from extents.c, use in range tables -------------------- ChangeLog entries follow: -------------------- src/ChangeLog addition: 2010-03-22 Ben Wing <ben@xemacs.org> * Makefile.in.in (objs): * array.c: * array.c (gap_array_adjust_markers): * array.c (gap_array_move_gap): * array.c (gap_array_make_gap): * array.c (gap_array_insert_els): * array.c (gap_array_delete_els): * array.c (gap_array_make_marker): * array.c (gap_array_delete_marker): * array.c (gap_array_delete_all_markers): * array.c (gap_array_clone): * array.h: * depend: * emacs.c (main_1): * extents.c: * extents.c (EXTENT_GAP_ARRAY_AT): * extents.c (extent_list_num_els): * extents.c (extent_list_locate): * extents.c (extent_list_at): * extents.c (extent_list_delete_all): * extents.c (allocate_extent_list): * extents.c (syms_of_extents): * extents.h: * extents.h (XEXTENT_LIST_MARKER): * lisp.h: * rangetab.c: * rangetab.c (mark_range_table): * rangetab.c (print_range_table): * rangetab.c (range_table_equal): * rangetab.c (range_table_hash): * rangetab.c (verify_range_table): * rangetab.c (get_range_table_pos): * rangetab.c (Fmake_range_table): * rangetab.c (Fcopy_range_table): * rangetab.c (Fget_range_table): * rangetab.c (put_range_table): * rangetab.c (Fclear_range_table): * rangetab.c (Fmap_range_table): * rangetab.c (unified_range_table_bytes_needed): * rangetab.c (unified_range_table_copy_data): * rangetab.c (unified_range_table_lookup): * rangetab.h: * rangetab.h (struct range_table_entry): * rangetab.h (struct Lisp_Range_Table): * rangetab.h (rangetab_gap_array_at): * symsinit.h: Rename dynarr.c to array.c. Move gap array from extents.c to array.c. Extract dynarr, gap array and stack-like malloc into new file array.h. Rename GAP_ARRAY_NUM_ELS -> gap_array_length(). Add gap_array_at(), gap_array_atp(). Rewrite range table code to use gap arrays. Make put_range_table() smarter so that its operation is O(log n) for adding a localized range. * gc.c (lispdesc_block_size_1): Don't ABORT() when two elements are located at the same place. This will happen with a size-0 gap array -- both parts of the array (before and after gap) are in the same place.

;;; Commentary:

;;; Code:

;; It is not particularly reasonable that iso-latin-1-with-esc has a
;; value of t for the safe-charsets property. We discourage its use,
;; though, and this behaviour is compatible with GNU.
