Handle double reduction in parloops
2015-07-28 Tom de Vries <tom@codesourcery.com>
* tree-parloops.c (reduc_stmt_res): New function.
(initialize_reductions, add_field_for_reduction)
(create_phi_for_local_result, create_loads_for_reductions)
(create_stores_for_reduction, build_new_reduction): Handle case that
reduc_stmt is a phi.
(gather_scalar_reductions): Allow double_reduc reductions.
* gcc.dg/autopar/uns-outer-4.c: Remove xfail on scan for parallelizing
outer loop.
* testsuite/libgomp.c/uns-outer-4.c: New test.
