3 ; This is mostly a "don't assert" test. The type of the RHS of a shift depended
4 ; on the phase of legalization, which led to the creation of an unexpected and
5 ; unselectable "rotr" node: (i32 (rotr i32, i64)).
7 ; FIXME: This test is xfailed because it relies on an optimization that has
8 ; been reverted (see PR17975).
