tree-vectorizer.h (vectorizable_function): Export.
2006-11-30 Richard Guenther <rguenther@suse.de>
* tree-vectorizer.h (vectorizable_function): Export.
* tree-vect-transform.c (vectorizable_function): Likewise.
* tree-vect-patterns.c (vect_recog_pow_pattern): Set
type_in to scalar type in recognition of squaring.
Make sure the target can vectorize sqrt in recognition
of sqrt, set type_in to vector type in this case.
* gcc.dg/vect/vect-pow-1.c: Rename ...
* gcc.dg/vect/fast-math-vect-pow-1.c: ... to this. Use
floats instead of doubles, check successful vectorization.
