Check TYPE_OVERFLOW_WRAPS for parloops reductions
2015-07-23 Tom de Vries <tom@codesourcery.com>
* tree-parloops.c (gather_scalar_reductions): Add arg to call to
vect_force_simple_reduction.
* tree-vect-loop.c (vect_analyze_scalar_cycles_1): Same.
(vect_is_simple_reduction_1): Add and handle
need_wrapping_integral_overflow parameter.
(vect_is_simple_reduction, vect_force_simple_reduction): Add and pass
need_wrapping_integral_overflow parameter.
(vectorizable_reduction): Add arg to call to vect_is_simple_reduction.
* tree-vectorizer.h (vect_force_simple_reduction): Add parameter to decl.
* gcc.dg/autopar/outer-4.c: Add xfail.
* gcc.dg/autopar/outer-5.c: Same.
* gcc.dg/autopar/outer-6.c: Same.
* gcc.dg/autopar/reduc-2.c: Same.
* gcc.dg/autopar/reduc-2char.c: Same.
