tree-vectorizer.h (vect_loop_versioning): Adjust prototype.
2012-04-25 Richard Guenther <rguenther@suse.de>
* tree-vectorizer.h (vect_loop_versioning): Adjust prototype.
* tree-vect-loop.c (vect_transform_loop): Adjust.
* tree-vect-loop-manip.c (vect_do_peeling_for_loop_bound): Record
the maximum number of iterations for the epilogue loop.
(vect_loop_versioning): Remove case re-using the peeled
epilogue loop.
