This revision is now accepted and ready to land.

I think I've seen calls which should be undef recently, but should stay in a dead code. This is the way our library works, and recently the same behavior seems to appear normal with hcc. It is still a fuzzy logic, but that is way we are handling differences between targets, so let it be.

I would still want to emit a call to an error reporting function though. Although I understand that is difficult to emit a good error from a GPU RT.
