; This regression test is defending against a TypeSize warning 'assumption that
; TypeSize is not scalable'. This warning cropped up in
; RuntimePointerChecking::insert when performing loop load elimination because
; this function was previously unaware of scalable types.

; If this check fails please read test/CodeGen/AArch64/README for instructions on how to resolve it.
