Yes. My plan is to make the Sema tests (that are quick to run) exhaustively test feature flag combinations to ensure correct diagnostic behaviour. Once this is in place I can start reducing the number of RUN lines in the CodeGen tests (that are slow to run) to the minimum required to verify Clang is emitting the correct IR.
