; This regression test is defending against a TypeSize warning 'assumption that TypeSize is not
; scalable'. This warning appeared in DAGCombiner::visitLIFETIME_END when visiting a LIFETIME_END
; node linked to a scalable store.

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