There is always the ugly approach of a global that defaults to 0 and
is set to 1 somewhere in jc1 initialization.

Yeah, I am kind of new to these tree optimizers, so I thought there might be some sort of official way to know these things.

For development and testing, I will just always run the pass. It might get some hits in C++ cni code, but it is exceedingly unlikely that it is at all useful for c, ada, fortran, etc.
