Hi,
this patch allows non-float reductions to be detected by graphite,
independent of whether fassociative-math (which only has effect for
float operations) is set.
Currently bootstrapping and reg-testing on x86_64.
OK for trunk?
Thanks,
- Tom

* graphite-sese-to-poly.c (build_poly_scop): Always call
rewrite_commutative_reductions_out_of_ssa.
