; This test shows an alloca of a struct and an array that can be reduced to
; multiple variables easily. However, the alloca is used by a store
; instruction, which was not possible before aggregrates were first class
; values. This checks of scalarrepl splits up the struct and array properly.

; RUN: opt < %s -scalarrepl -S | not grep alloca
