------- Comment #5 from rguenth at gcc dot gnu dot org 2010-06-26 14:25 -------
I now see compile-time on polyhedron sky-rocketed with enabling prefetching at
-O3 by default. See
http://gcc.opensuse.org/c++bench/polyhedron/polyhedron-summary.txt-1-0.html
This isn't acceptable - please work on this.
