(scopdet_basic_block_info): Call graphite_cannot_represent_loop_niter. (graphite_loop_normal_form): Use gcc_assert. (scan_tree_for_params): Use CASE_CONVERT. (phi_node_is_iv, bb_contains_non_iv_scalar_phi_nodes): New. (build_scop_conditions_1): Call bb_contains_non_iv_scalar_phi_nodes. Use gcc_assert. Discard scops that contain unhandled cases. (build_scop_conditions): Return a boolean status for unhandled cases. (strip_mine_profitable_p): Print the loop number, not its depth. (is_interchange_valid): Pass the depth of the loop nest, don't recompute it wrongly. (graphite_trans_bb_block): Same. (graphite_trans_bb_block): Print tentative of loop blocking. (graphite_trans_scop_block): Do not print that the loop has been blocked. (graphite_transform_loops): Do not handle scops that contain condition scalar phi nodes. * testsuite/gcc.dg/graphite/pr38500.c: Fixed warning as committed in trunk. * testsuite/gcc.dg/graphite/block-0.c: Update test. * testsuite/gcc.dg/graphite/block-1.c: Same. * testsuite/gcc.dg/graphite/block-2.c: Remove xfail and test for blocking. * testsuite/gcc.dg/graphite/block-4.c: Remove test for strip mine. * testsuite/gcc.dg/graphite/block-3.c: New. * testsuite/gcc.dg/graphite/pr38498.c: New.
