As Eric mentioned, please put an assert to verify that the call from the c6x backend never fails.
I'd be happiest if we had an assert on almost all targets. regrename has been designed in such a way that the replacements can't fail, if the constraints on the insns are correct. If there are ports which have borderline insns where that doesn't hold maybe we ought to have a target hook that says so.
