Yes, perhaps.  The way I understand things work now is that GENERIC is
used to do tree rewriting transforms/optimizations, and then the resulting
trees are returned to the front-end.  The front-end plays a little more,
then calls expanders to generate RTL.  It's as if the GENERIC stuff is
not a real layer, just a subroutine of front-ends.  If direct
GENERIC-layer compilation of new synthetic functions was desirable
in the long run, then the above control flow would first have to be
changed for ordinary functions.
