; REQUIRES: asserts
; Test that reserved argument area is shared between the memcpy call and the
; call to f2. This eliminates the nested call sequence nodes.
; Also, test that a basic call to memcpy reserves its outgoing argument area.
; FIXME: We should also be explicit about testing that the loads for the
; arguments are scheduled after the memcpy, but that wasn't enforced in
; this patch.
