The exact reason should be found, since this should be OK. Also, this should be setting no-nans-fp-math / no-infs-fp-math and whatever others there are. unsafe-fp-math should just be controlling other algebraic kinds of optimizations _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev
