; This is mostly a "don't assert" test. The type of the RHS of a shift depended
; on the phase of legalization, which led to the creation of an unexpected and
; unselectable "rotr" node: (i32 (rotr i32, i64)).

; FIXME: This test is xfailed because it relies on an optimization that has
; been reverted (see PR17975).
; XFAIL: *
