annotate lib-src/make-path.c @ 5182:2e528066e2fc
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.)
