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.
