Add compiler macros for #'equal, #'member, ... where #'eq, #'memq appropriate. lisp/ChangeLog addition: 2012-05-07 Aidan Kehoe <kehoea@parhasard.net> * cl-macs.el: * cl-macs.el (cl-non-fixnum-number-p): Rename, to cl-non-immediate-number-p. This is a little more informative as a name, though still not ideal, in that it will give t for some immediate fixnums on 64-bit builds. * cl-macs.el (eql): * cl-macs.el (define-star-compiler-macros): * cl-macs.el (delq): * cl-macs.el (remq): Use the new name. * cl-macs.el (cl-equal-equivalent-to-eq-p): New. * cl-macs.el (cl-car-or-pi): New. * cl-macs.el (cl-cdr-or-pi): New. * cl-macs.el (equal): New compiler macro. * cl-macs.el (member): New compiler macro. * cl-macs.el (assoc): New compiler macro. * cl-macs.el (rassoc): New compiler macro. If any of #'equal, #'member, #'assoc or #'rassoc has a constant argument such that #'eq, #'memq, #'assq or #'rassq, respectively, are equivalent, make the substitution. Relevant in files like ispell.el, there's a reasonable amount of code out there that doesn't quite get the distinction.
