+ * graphite-sese-to-poly.c (rewrite_close_phi_out_of_ssa): Add back
+ the case removed in the previous patch, when the only phi argument
+ is defined in the same loop as the phi node itself. Handle it
+ separately from the invariant case by both propagating it outside
+ the region and replacing the phi node with an assign.
