From 871a0725ddee3c9ef8cf827cb85ce08e150fec44 Mon Sep 17 00:00:00 2001 From: Richard Biener Date: Mon, 25 Sep 2017 09:48:31 +0000 Subject: graphite-optimize-isl.c (optimize_isl): Fail and dump if ISL errors other than isl_error_quota happen. 2017-09-25 Richard Biener * 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.
