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.
