* tree-check.c (operator_is_linear, scev_is_linear_expression): New.
* tree-chrec.h (scev_is_linear_expression): Declared.
* graphite.c (graphite_cannot_represent_loop_niter): New.
(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.
