My port defines all the address legitimizing target hooks, but none
are called with the address in question. Where/how is the address
supposed to be fixed-up in this case? Or, where/how does gcc avoid
producing an illegitimate address in the first place?
I'm not sure they are ever legitimized -- IIRC caller-save tries to only
generate addressing modes which are safe for precisely this reason.
