; This test is to verify gc.relocate can handle pointer to vector of
; pointers (ptr addrspace(1) in this case).
; The old scheme to create a gc.relocate of ptr addrspace(1)
; type will fail because llvm does not support mangling vector of pointers.
; The new scheme will create all gc.relocate to ptr addrspace(1) type and
; then bitcast to the correct type.
