// Swift globals are not currently serialized. However, addressor
// declarations are serialized when all these three flags are present:
// -emit-module -parse-as-library -sil-serialize-all
//
// The only way to inspect the serialized module is sil-opt. The swift
// driver will only output the SIL that it deserializes.
