        * tree-vect-transform.c (vectorizable_operation): Return false for
        scalar shift operations and for vector shift operations with
        non-invariant shift arguments.  Use scalar tree operand op1 as
        a shift operand when vector shift insn pattern uses scalar shift
        operand.
        * Makefile.in (tree-vect-transform.o): Depend on recog.h.
