Isl is needed only for the graphite loop optimization features of gcc. But then that leads to a new question: How important and/or useful is the gcc-graphite optimization? AFAIK it does improve performance in many cases. Also, as opposed to link-time optimization (LTO), gcc-graphite is stable. Since gcc-5.1.0 is not that urgent, I'll wait until the isl problem is sorted out. Frank Peters
