// This test intentionally mirrors /Driver/emit-sib-single-file to ensure that
// SwiftOnoneSupport is always a dependency of -Onone -emit-si*gen builds.

// FIXME: The Frontend's understanding of the situations in which to load
// SwiftOnoneSupport is a tacit part of the rest of the compile pipeline and
// pervades the AST.  SIL could probably sink knowledge of module dependencies
// internally and make this test unnecessary.
