tree-vect-loop.c (needs_fold_left_reduction_p): Export.
2019-10-17 Richard Biener <rguenther@suse.de>
* tree-vect-loop.c (needs_fold_left_reduction_p): Export.
(vect_is_simple_reduction): Move all validity checks ...
(vectorizable_reduction): ... here. Compute whether we
need a fold-left reduction here.
* tree-vect-patterns.c (vect_reassociating_reduction_p): Merge
both overloads, check needs_fold_left_reduction_p directly.
* tree-vectorizer.h (needs_fold_left_reduction_p): Declare.
