Function passes may run concurrently on different functions. Therefore, they should generally avoid looking at adjacent functions as that would cause race conditions. I'm not sure what will happen here as each pass may be computing its own instance of the liveness analysis scoped to the function it operates on so it may have no info at all about other functions. A straightforward fix to this is to make this a module pass so it cannot run on functions.
