; This file checks that the fallback path to selection dag works.
; The test is fragile in the sense that it must be updated to expose
; something that fails with global-isel.
; When we cannot produce a test case anymore, that means we can remove
; the fallback path.

; Check that we fallback on invoke translation failures.
