; The CHECK prefix is being used by those targets that do not support FastISel.
; By checking that we don't emit the "FastISel missed terminator..." message,
; we ensure that we do not generate code through FastISel.

; CHECK-NOT: FastISel missed terminator:   ret i64 0

; The above CHECK will only be valid as long as we *do* emit the missed
; terminator message for targets that support FastISel. If we add support
; for i64 return values in the future, then the following FISEL check-prefix
; will fail and we will have to come up with a new test.

; FISEL: FastISel missed terminator:   ret i64 0
