Move the heavy lifting from cl-seq.el to C.
src/ChangeLog addition:
2010-12-30 Aidan Kehoe <kehoea@parhasard.net>
Move the heavy lifting from cl-seq.el to C, finally making those
functions first-class XEmacs citizens, with circularity checking,
built-in support for tests other than #'eql, and as much
compatibility with current Common Lisp as Paul Dietz' tests require.
* fns.c (check_eq_nokey, check_eq_key, check_eql_nokey)
(check_eql_key, check_equal_nokey, check_equal_key)
(check_equalp_nokey, check_equalp_key, check_string_match_nokey)
(check_string_match_key, check_other_nokey, check_other_key)
(check_if_nokey, check_if_key, check_match_eq_key)
(check_match_eql_key, check_match_equal_key)
(check_match_equalp_key, check_match_other_key): New. These are
basically to provide function pointers to be used by Lisp
functions that take TEST, TEST-NOT and KEY arguments.
(get_check_match_function_1, get_check_test_function)
(get_check_match_function): These functions work out which of the
previous list of functions to use, given the keywords supplied by
the user.
(count_with_tail): New. This is the bones of #'count.
(list_count_from_end, string_count_from_end): Utility functions
for #'count.
(Fcount): New, moved from cl-seq.el.
(list_position_cons_before): New. The implementation of #'member*,
and important in implementing various other functions.
(FmemberX, Fadjoin, FassocX, FrassocX, Fposition, Ffind)
(FdeleteX, FremoveX, Fdelete_duplicates, Fremove_duplicates)
(Fnsubstitute, Fsubstitute, Fsublis, Fnsublis, Fsubst, Fnsubst)
(Ftree_equal, Fmismatch, Fsearch, Fintersection, Fnintersection)
(Fsubsetp, Fset_difference, Fnset_difference, Fnunion, Funion)
(Fset_exclusive_or, Fnset_exclusive_or): New, moved here from
cl-seq.el.
(position): New. The implementation of #'find and #'position.
(list_delete_duplicates_from_end, subst, sublis, nsublis)
(tree_equal, mismatch_from_end, mismatch_list_list)
(mismatch_list_string, mismatch_list_array)
(mismatch_string_array, mismatch_string_string)
(mismatch_array_array, get_mismatch_func): Helper C functions for
the Lisp-visible functions.
(venn, nvenn): New. The implementation of the main Lisp functions that
treat lists as sets.
lisp/ChangeLog addition:
2010-12-30 Aidan Kehoe <kehoea@parhasard.net>
* cl-seq.el:
Move the heavy lifting from this file to C. Dump the
cl-parsing-keywords macro, but don't use defun* for the functions
we define that do take keywords, dynamic scope lossage makes that
not practical.
* subr.el (sort, fillarray): Move these aliases here.
(map-plist): #'nsublis is now built-in, but at this point #'eql
isn't necessarily available as a test; use #'eq.
* obsolete.el (cl-delete-duplicates): Make this available for old
compiler macros and old code.
(memql): Document that this is equivalent to #'member*, and worse.
* cl.el (adjoin, subst): Removed. These are in C.
