-;;;; pointer.
+;;;; Current-Catch and the alien stack pointer. (Before sbcl-0.7.0,
+;;;; when there were IR1 and byte interpreters, we had to save
+;;;; the interpreter "eval stack" too.)
;;;;
-;;;; We don't need to save/restore the current unwind-protect, since
-;;;; unwind-protects are implicitly processed during unwinding.
+;;;; We don't need to save/restore the current UNWIND-PROTECT, since
+;;;; UNWIND-PROTECTs are implicitly processed during unwinding.
;;;;
;;;; We don't need to save the BSP, because that is handled automatically.
-;;; Return a list of TNs that can be used to snapshot the dynamic state for
-;;; use with the Save/Restore-Dynamic-Environment VOPs.
