We are slowly trying to replace the throwaway driver f18. That's actually a good progress.
Thank you for the progress @awarzynski @FarisRehman
I would wait for others to approve as this patch touches the core Fortran parts.

This change:

  • preserves the current behavior when FLANG_BUILD_NEW_DRIVER=OFF
  • adds a lot of new tests for flang-new when FLANG_BUILD_NEW_DRIVER=ON at almost no cost

Really nice to see this patch! I have two suggestions for the future:

  • when flang-new becomes flang, we should update flang-driver accordingly
  • also, we could switch to flang-new -fc1 instead of flang-new

I don't see a good reason for these to happen just now - one step at a time! LGTM

You could change %flang-driver and %flang-new to %flang now. That way it wouldn't be necessary to change all of the tests again.

I'm guessing that this was added by accident ;-) Don't forget to revert before committing to main.
