tree-vect-data-refs.c (vect_preserves_scalar_order_p): Make sure to use non-pattern stmts for get_earlier_stmt arguments.
2018-05-29 Richard Biener <rguenther@suse.de>
* tree-vect-data-refs.c (vect_preserves_scalar_order_p): Make
sure to use non-pattern stmts for get_earlier_stmt arguments.
* tree-vectorizer.h (get_earlier_stmt): Assert we do not get
called on pattern stmts.
(get_later_stmt): Likewise.
