What code are you loking at; where do you see a textual
prologue?  No such thing for CRIS since a while; not even
defining the asm-prologue/epilogue hooks.  I see two stray
obsolete comments in cris.h though.

There *is* an option to omit the prologue and epologue
controlling the TARGET_PROLOGUE_EPILOGUE; I'm guessing that
could cause confusion.  Is that getting in the way of something?
If so, I think the unsuccessful expansion/presence of "prologue"
and "epilogue" should be decoupled from the use of the asm
prologue and epilogue hooks (and just be ignored).

(If you instead meant MMIX, the asm-prologue/epilogue hooks are
used only for marking, similar to other targets.)
