In general this can not be done. gcc has a pretty strong split
between the frontend and the backend. You can't refer to frontend
structures in the backend.
It's pretty hard to think of any reason why something as low-level as
ASM_OUTPUT_LABEL_REF would want to look at anything in the frontend.
You are probably working at the wrong level.
