graphite-optimize-isl.c (optimize_isl): Fail and dump if ISL errors other than isl_error_quota happen.
2017-09-25 Richard Biener <rguenther@suse.de> * graphite-optimize-isl.c (optimize_isl): Fail and dump if ISL errors other than isl_error_quota happen. Dump if the schedule is the same. * graphite-sese-to-poly.c (build_poly_scop): Fail on ISL errors instead of aborting inside ISL. From-SVN: r253142
