The build scripts for foundation bypass the Swift driver and use the -frontend mode directly. The command line interface for -frontend is not officially supported and is subject to change. A recent change was that when merging partial modules to form a final module file, the -sil-merge-partial-modules flag must be passed in so that serialized SIL can be preserved in the final module file. Preserving serialized SIL is now a requirement, since soon default argument generators and stored property initializers will be emitted with non-public linkage, requiring clients to deserialize SIL when calling these entry points.
