Have #'sort*, #'merge use the same test approach as functions from cl-seq.el 2011-02-05 Aidan Kehoe <kehoea@parhasard.net> * fns.c: * fns.c (check_lss_key, check_lss_key_car): New. * fns.c (check_string_lessp_key check_string_lessp_key_car): New. * fns.c (get_merge_predicate): New. * fns.c (list_merge): * fns.c (array_merge): * fns.c (list_array_merge_into_list): * fns.c (list_list_merge_into_array): * fns.c (list_array_merge_into_array): * fns.c (Fmerge): * fns.c (list_sort): * fns.c (array_sort): * fns.c (FsortX): * fns.c (syms_of_fns): * lisp.h: Move #'sort, #'merge to using the same test approach as is used in the functions that take TEST, TEST-NOT and KEY arguments. This allows us to avoid the Ffuncall() overhead when the most common PREDICATE arguments are supplied, in particular #'< and #'string-lessp. * fontcolor-msw.c (sort_font_list_function): * fontcolor-msw.c (mswindows_enumerate_fonts): * dired.c: * dired.c (Fdirectory_files): * fileio.c: * fileio.c (build_annotations): * fileio.c (syms_of_fileio): * keymap.c: * keymap.c (keymap_submaps): * keymap.c (map_keymap_sort_predicate): * keymap.c (describe_map_sort_predicate): * keymap.c (describe_map): Change the various C predicates passed to list_sort () and list_merge () to fit the new calling convention, returning non-zero if the first argument is less than the second, zero otherwise.
