; SROA should be able to handle the mixed types and eliminate the allocas here.

; TODO: Currently it does this by falling back to integer "bags of bits".
; With enough cleverness, it should be possible to convert between <3 x i32>
; and <2 x i64> by using a combination of a bitcast and a shuffle.

; CHECK-NOT: alloca
