Integrate CL code better into core, remove obsolete compatibility code. lisp/ChangeLog addition: 2011-12-30 Aidan Kehoe <kehoea@parhasard.net> * bytecomp.el: Call #'cl-compile-time-init explicitly here, don't rely on bytecomp-load-hook for what is core functionality. * cl-extra.el: * cl-extra.el (require): * cl-extra.el (make-random-state): * cl-extra.el (random-state-p): * cl-extra.el (make-hashtable): Removed. * cl-extra.el (make-weak-hashtable): Removed. * cl-extra.el (make-key-weak-hashtable): Removed. * cl-extra.el (make-value-weak-hashtable): Removed. * cl-extra.el ('hashtablep): Removed. * cl-extra.el ('hashtable-fullness): Removed. * cl-extra.el ('hashtable-test-function): Removed. * cl-extra.el ('hashtable-type): Removed. * cl-extra.el ('hashtable-size): Removed. * cl-extra.el ('copy-hashtable): Removed. * cl-extra.el (cl-builtin-gethash): Removed. * cl-extra.el (cl-builtin-remhash): Removed. * cl-extra.el (cl-builtin-clrhash): Removed. * cl-extra.el (cl-builtin-maphash): Removed. * cl-extra.el ('cl-gethash): Removed. * cl-extra.el ('cl-puthash): Removed. * cl-extra.el ('cl-remhash): Removed. * cl-extra.el ('cl-clrhash): Removed. * cl-extra.el ('cl-maphash): Removed. * cl-extra.el ('cl-make-hash-table): Removed. * cl-extra.el ('cl-hash-table-p): Removed. * cl-extra.el ('cl-hash-table-count): Removed. * cl-extra.el (cl-prettyexpand): * cl-extra.el (names): Remove compatibility aliases from this file. In #'cl-prettyexpand, if FULL is nil, don't expand return-from either, for symmetry with not expanding block. Drop cl-extra-load-hook, it's useless when cl-extra is dumped (since third-party code can't use it, and dumped code shouldn't use it.) * cl-macs.el: * cl-macs.el (cl-pop2): * cl-macs.el (defun*): * cl-macs.el (cl-parse-loop-clause): Remove some no-longer-needed compatibility kludges. * cl.el: * cl.el ('cl-map-extents): Removed. * cl.el (cl-random-time): * cl.el (list*): New, moved back from subr.el, given a shorter implementation. * cl.el ('cl-member): Removed. * cl.el ('cl-floor): Removed. * cl.el ('cl-ceiling): Removed. * cl.el ('cl-truncate): Removed. * cl.el ('cl-round): Removed. * cl.el ('cl-mod): Removed. Remove some compatibility aliases; these may conflict with package usage, in which case the packages need to be updated, the new names are available in 21.4, and that's the most recent version we support. * cl.el (cl-hacked-flag): Removed. * cl.el (cl-hack-byte-compiler): Removed. * subr.el: * subr.el (list*): Moved back to cl.el. * update-elc-2.el (batch-update-elc-2): * update-elc.el (do-autoload-commands): Add an autoload for cl-compile-time-init in these two files, they run on bare temacs, auto-autoload isn't available to them, and now bytecomp calls cl-compile-time-init explicitly. * cl-compat.el: Removed. This file was long obsolete. man/ChangeLog addition: 2011-12-30 Aidan Kehoe <kehoea@parhasard.net> * cl.texi (Top): * cl.texi (Usage): * cl.texi (Organization): * cl.texi (Efficiency Concerns): * cl.texi (Common Lisp Compatibility): Remove documentation of cl-compat, now it's deleted.
