re PR middle-end/37150 (basic-block vectorization misses some unrolled loops)
2016-11-07 Richard Biener <rguenther@suse.de>
PR tree-optimization/37150
* tree-vectorizer.h (vect_transform_slp_perm_load): Add n_perms
parameter.
* tree-vect-slp.c (vect_supported_load_permutation_p): Adjust.
(vect_analyze_slp_cost_1): Account for the real number of
permutations emitted and for dead loads.
(vect_transform_slp_perm_load): Add n_perms parameter counting
the number of emitted permutations.
* tree-vect-stmts.c (vectorizable_load): Adjust.
