Fix PR48805: Do not instantiate ADDR_EXPRs
With this patch we avoid instantiating ADDR_EXPR: it makes no sense to translate &b[i] into &b[{0, +, 1}_1]. Bootstrapped and tested on amd64-linux. 2011-07-26 Sebastian Pop <sebastian.pop@amd.com> PR middle-end/48805 * tree-scalar-evolution.c (instantiate_scev_r): Return chrec_dont_know for ADDR_EXPR. * gcc.dg/graphite/id-pr48805.c: New.
