It seems that the answer is 'no'.

For the front-end, you need to modify the ScopDetection pass so it
accepts the irregular stuffs, and you also need to modify the ScopInfo
pass so it can translate those irregular stuffs to polyhedral
representation correctly.

I am not familar with the backend, cced to tobi.
