Move #'sort*, #'fill, #'merge to C from cl-seq.el. lisp/ChangeLog addition: 2010-04-01 Aidan Kehoe <kehoea@parhasard.net> * cl-seq.el (fill, sort*, merge): Move these functions to fns.c. (stable-sort): Make this docstring reflect the argument names used in the #'sort* docstring. * cl-macs.el (stable-sort): Make #'stable-sort exactly equivalent to #'sort* in compiled code. * bytecomp.el (byte-compile-maybe-add-*): New macro, for functions like #'sort and #'mapcar that, to be strictly compatible, should only take two args, but in our implementation can take more, because they're aliases of #'sort* and #'mapcar*. (byte-compile-mapcar, byte-compile-sort, byte-compile-fillarray): Use this new macro. (map-into): Add a byte-compile method for #'map-into in passing. * apropos.el (apropos-print): Use #'sort* with a :key argument, now it's in C. * compat.el (extent-at): Ditto. * register.el (list-registers): Ditto. * package-ui.el (pui-list-packages): Ditto. * help.el (sorted-key-descriptions): Ditto. src/ChangeLog addition: 2010-03-31 Aidan Kehoe <kehoea@parhasard.net> * fns.c (STRING_DATA_TO_OBJECT_ARRAY) (BIT_VECTOR_TO_OBJECT_ARRAY, c_merge_predicate_key) (c_merge_predicate_nokey, list_merge, array_merge) (list_array_merge_into_list, list_list_merge_into_array) (list_array_merge_into_array, CHECK_KEY_ARGUMENT, Fmerge) (list_sort, array_sort, FsortX): Move #'sort*, #'fill, #'merge from cl-seq.el to C, extending the implementations of Fsort, Ffillarray, and merge() to do so. * keymap.c (keymap_submaps, map_keymap_sort_predicate) (describe_map_sort_predicate): Change the calling semantics of the C sort predicates to return a non-nil Lisp object if the first argument is less than the second, rather than C integers. * fontcolor-msw.c (sort_font_list_function): * fileio.c (build_annotations): * dired.c (Fdirectory_files): * abbrev.c (Finsert_abbrev_table_description): Call list_sort instead of Fsort, list_merge instead of merge() in these functions. man/ChangeLog addition: 2010-04-01 Aidan Kehoe <kehoea@parhasard.net> * lispref/lists.texi (Rearrangement): Update the documentation of #'sort here, now that it accepts any type of sequence and the KEY keyword argument. (Though this is probably now the wrong place for this function, given that.)
