Move the various map* functions to C; add #'map-into.
src/ChangeLog addition:
2010-01-31 Aidan Kehoe <kehoea@parhasard.net>
Move #'mapcar*, #'mapcan, #'mapc, #'map, #'mapl, #'mapcon to C;
extend #'mapvector, #'mapconcat, #'mapcar to support more
SEQUENCES; have them all error with circular lists.
* fns.c (Fsubseq): Call CHECK_SEQUENCE here; Flength can return
from the debugger if it errors with a non-sequence, leading to a
crash in Fsubseq if sequence really is *not* a sequence.
(mapcarX): Rename mapcar1 to mapcarX; rework it comprehensively to
take an optional lisp output argument, and a varying number of
sequences.
Special-case a single list argument, as we used to, saving its
elements in the stack space for the results before calling
FUNCTION, so FUNCTION can corrupt the list all it
wants. dead_wrong_type_argument() in the other cases if we
encounter a non-cons where we expected a cons.
(Fmapconcat):
Accept further SEQUENCES after separator here. Special-case
the idiom (mapconcat 'identity SEQUENCE), don't even funcall.
(FmapcarX): Rename this from Fmapcar. Accept optional SEQUENCES.
(Fmapvector): Accept optional SEQUENCES.
(Fmapcan, Fmapc, Fmap): Move these here from cl-extra.el.
(Fmap_into): New function, as specified by Common Lisp.
(maplist): New function, the guts of the implementation of
Fmaplist and Fmapl.
(Fmaplist, Fmapl, Fmapcon): Move these from cl-extra.el.
(syms_of_fns):
Add a few needed symbols here, for the type tests
used by #'map. Add the new subrs, with aliases for #'mapc-internal
and #'mapcar.
* general-slots.h: Declare Qcoerce here, now it's used in both
indent.c and fns.c
* indent.c (syms_of_indent): Qcoerce is gone from here.
* lisp.h: Add ARRAYP(), SEQUENCEP(), and the corresponding CHECK_*
macros. Declare Fbit_vector, Fstring, FmapcarX, now other files
need to use them.
* data.c (Farrayp, Fsequencep): Use ARRAYP and SEQUENCEP, just
added to lisp.h
* buffer.c (Fbuffer_list): Now Fmapcar has been renamed FmapcarX
and takes MANY arguments, update this function to reflect that.
lisp/ChangeLog addition:
2010-01-31 Aidan Kehoe <kehoea@parhasard.net>
* cl.el (mapcar*): Delete; this is now in fns.c.
Use #'mapc, not #'mapc-internal in a couple of places.
* cl-macs.el (mapc, mapcar*, map): Delete these compiler macros
now the corresponding functions are in fns.c; there's no run-time
advantage to the macros.
* cl-extra.el (coerce): Extend the possible conversions here a
little; it's not remotely comprehensive yet, though it does allow
running slightly more Common Lisp code than previously.
(cl-mapcar-many): Delete.
(map, maplist, mapc, mapl, mapcan, mapcon): Move these to fns.c.
* bytecomp.el (byte-compile-maybe-mapc):
Use #'mapc itself, not #'mapc-internal, now the former is in C.
(mapcar*): Use #'byte-compile-maybe-mapc as this function's
byte-compile method, now a #'mapc that can take more than one
sequence is in C.
* obsolete.el (cl-mapc): Move this compatibility alias to this file.
* update-elc.el (do-autoload-commands): Use #'mapc, not
#'mapc-internal here.
