Hi there,

what we do here at Quarkslab is a combination of:

- unittesting the pass (through lit)
- fuzzing the passes (through csmith & through various optimization flag
  combination)
- running the test suite of various open source project compiled with
  our pass activated (as you do)

hope it helps,
