re PR tree-optimization/84037 (Speed regression of polyhedron benchmark since r256644)
2018-02-07 Richard Biener <rguenther@suse.de>
PR tree-optimization/84037
* tree-vectorizer.h (struct _loop_vec_info): Add ivexpr_map member.
(cse_and_gimplify_to_preheader): Declare.
(vect_get_place_in_interleaving_chain): Likewise.
* tree-vect-loop.c (_loop_vec_info::_loop_vec_info): Initialize
ivexpr_map.
(_loop_vec_info::~_loop_vec_info): Delete it.
(cse_and_gimplify_to_preheader): New function.
* tree-vect-slp.c (vect_get_place_in_interleaving_chain): Export.
* tree-vect-stmts.c (vectorizable_store): CSE base and steps.
(vectorizable_load): Likewise. For grouped stores always base
the IV on the first element.
* tree-vect-loop-manip.c (vect_loop_versioning): Unshare versioning
condition before gimplifying.
