- ;; A special kind of TN used to represent initialization of local
- ;; call arguments in the caller. It provides another name for the
- ;; argument TN so that lifetime analysis doesn't get confused by
- ;; self-recursive calls. Lifetime analysis treats this the same

- ;; the original TN and replaces all uses of the alias with the
- ;; original TN. SAVE-TN holds the aliased TN.
