disassembly

Below is the assembly output for the following function:

;;; Note that dispatch-entry is a lisp structure. This is sorta equivalent
;;; to a C structure, the way they are stored is very similar
(defun dispatch-entry-equal (entry1 entry2)
  (declare (dispatch-entry entry1 entry2))
  (equal (dispatch-entry-type entry1)
         (dispatch-entry-type entry2)))
