Avoid calling verify_ssa twice in verify_loop_closed_ssa.
2010-04-06 Sebastian Pop <sebastian.pop@amd.com>
* graphite-clast-to-gimple.c (graphite_verify): Remove redundant
call to verify_ssa. Invoke verify_loop_closed_ssa with an extra
argument.
* graphite-scop-detection.c (canonicalize_loop_closed_ssa_form): Same.
* graphite-sese-to-poly.c (rewrite_reductions_out_of_ssa): Same.
(rewrite_commutative_reductions_out_of_ssa): Same.
* passes.c (execute_function_todo): Call verify_ssa for every pass
in the LNO. Invoke verify_loop_closed_ssa with an extra argument.
* tree-flow.h (verify_loop_closed_ssa): Update declaration.
* tree-parloops.c (parallelize_loops): Invoke verify_loop_closed_ssa
with an extra argument.
* tree-ssa-loop-manip.c (check_loop_closed_ssa_stmt): Same. Call
verify_ssa only when the extra argument is true.
(gimple_duplicate_loop_to_header_edge): Invoke verify_loop_closed_ssa
with an extra argument.
(tree_transform_and_unroll_loop): Same.
