; This test lets globalopt split the global struct and array into different
; values. This used to crash, because globalopt forgot to put the new var in the
; same address space as the old one.
; RUN: opt < %s -globalopt -S | FileCheck %s
; Check that the new global values still have their address space
; CHECK: addrspace(1) global
; CHECK: addrspace(1) global
