2015-07-17[graphite] fix pr61929Aditya Kumar2-0/+25
This fixes bootstrap of GCC with BOOT_CFLAGS="-g -O2 -fgraphite-identity -floop-nest-optimize -floop-block -floop-interchange -floop-strip-mine". It passes regstrap on amd64-linux. A previous change (https://gcc.gnu.org/viewcvs/gcc?view=revision&revision=213816), replaced isl_int with isl_val because isl_int would be deprecated. Since isl_val has stricter checks, it exposed the bug. In the test case (isl_set_max_val) would return infinity which would remain unchecked. We now check if the value returned is an integer or not, and bail out if it isn't. The other problem was that we were allowing all kinds of data-refs in a scop. Now we discard a scop if it has any date-ref other than (ARRAY_REF, MEM_REF, COMPONENT_REF).
