Maybe we could add something > similar to that to Clang's driver? (`-driver-only`) Creating a specialized > `-MJ-only` seems too specific IMO. Sure, `-driver-only` makes sense to me: - Run driver, including side effects. - Don't run actions. It'd be worth testing that it works correctly with `-v`. My intuition is that `-driver-only -v` should do the same thing as `-###`, except that `-###` suppresses driver outputs that come before running the actions.
