re PR middle-end/41193 (slow compilation with graphite / ice with graphite)
2009-10-15 Sebastian Pop <sebastian.pop@amd.com>
* graphite-sese-to-poly.c (insert_copyin): Use gsi_insert_seq_on_edge.
(rewrite_commutative_reductions_out_of_ssa): Call gsi_commit_edge_inserts,
and check the SSA representation.
* gfortran.dg/graphite/id-18.f90: New, reduced from PR41193.
