[Bug middle-end/44576] [4.5/4.6 Regression] testsuite/gfortran.dg/zero_sized_1.f90 with huge compile time on prefetching + peeling

[rguenth at gcc dot gnu dot org]

------- 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.
