;;;; Compiler optimization settings.

;;; To recompile code with different compiler optimization settings, rebind

(defparameter *optimize-default*
'(optimize (compilation-speed 0) (debug 3) (safety 3) (space 1) (speed 1))
"Compiler optimization settings that emphasize debugging over speed. Most
code should use these settings.")
(defparameter *optimize-fast-unsafe*
;; Use the default debugging level.
'(optimize (compilation-speed 0) (debug 2) (safety 0) (space 1) (speed 3))
"Compiler optimization settings that emphasize speed at the expense of
debugging and run-time safety. Only low-level performance sensitive code that
has been extensively tested should use these settings.")
