Here's the change which added the ability to have prologues and epilogues
as RTL.  I was close -- that support wil be a decade old at the end of this

        * toplev.c (rest_of_compilation): Thread the prologue and epilogue
        code immediately after reloading is done.
        * sched.c (schedule_insns): Reposition the prologue and epilogue
        notes as needed.
[ ...]
        * m88k.md (prologue, epilogue, profiler, locate1, locate2): New
        patterns for representing prologues and epilogues.

I don't think the CRIS port existed back in 1992, or if it did, it
certainly wasn't in the public sources.
