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.
