// Make sure we emit the proper addrspacecast for llvm.used.  PR22383 exposed an
// issue where we were generating a bitcast instead of an addrspacecast.

// CHECK: @llvm.used = appending global [1 x i8*] [i8* addrspacecast (i8 addrspace(1)* bitcast ([0 x i32] addrspace(1)* @a to i8 addrspace(1)*) to i8*)], section "llvm.metadata"
