; arm64 has a separate copy as aarch64-neon-v1i1-setcc.ll

; This file test the DAG node like "v1i1 SETCC v1i64, v1i64". As the v1i1 type
; is illegal in AArch64 backend, the legalizer tries to scalarize this node.
; As the v1i64 operands of SETCC are legal types, they will not be scalarized.
; Currently the type legalizer will have an assertion failure as it assumes all
; operands of SETCC have been legalized.
; FIXME: If the algorithm of type scalarization is improved and can legaize
; "v1i1 SETCC" correctly, these test cases are not needed.
