* 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. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@119362 138bc75d-0d04-0410-961f-82ee72b054a4
