tree-vect-patterns.c (vect_recog_vector_vector_shift_pattern): Properly set vector type of the intermediate stmt.
2018-06-13 Richard Biener <rguenther@suse.de>
* tree-vect-patterns.c (vect_recog_vector_vector_shift_pattern):
Properly set vector type of the intermediate stmt.
* tree-vect-stmts.c (vectorizable_operation): The destination
var always has vectype_out type.
