- Tests that depend on emitted interfaces should generally use flags that are typical for modules that have textual interfaces (e.g. `-enable-library-evolution`). - If a test is intended to produce a valid `swiftinterface` then it should verify that interface. This will help prevent interface printing regressions caused by compiler changes. - Having commonly used substitutions for tests that emit interfaces makes it easy to experiment with compiler flags that might effect interface printing.
