;; A TN used for saving a :NORMAL TN across function calls. The
;; lifetime information slots are unitialized: get the original
- ;; TN our of the SAVE-TN slot and use it for conflicts. SAVE-ONCE
+ ;; TN out of the SAVE-TN slot and use it for conflicts. SAVE-ONCE
;; is like :SAVE, except that it is only save once at the single
;; writer of the original TN.

;;; The GLOBAL-CONFLICTS structure represents the conflicts for global
;;; TNs. Each global TN has a list of these structures, one for each
-;;; block that it is live in. In addition to repsenting the result of

;;; lifetime analysis, the global conflicts structure is used during
;;; lifetime analysis to represent the set of TNs live at the start of
