re PR tree-optimization/66051 (can't vectorize reductions inside an SLP group)
2015-12-03 Richard Biener <rguenther@suse.de>
PR tree-optimization/66051
* tree-vect-slp.c (vect_build_slp_tree_1): Remove restriction
on load group size. Do not pass in vectorization_factor.
(vect_transform_slp_perm_load): Do not require any permute support.
(vect_build_slp_tree): Do not pass in vectorization factor.
(vect_analyze_slp_instance): Do not compute vectorization
factor estimate. Use vector size instead of vectorization factor
estimate to split store groups for BB vectorization.
* gcc.dg/vect/slp-42.c: New testcase.
