sh.h (REG_CLASS_HAS_FP_REG): New.

Wed Dec 11 19:05:05 2002  J"orn Rennecke <joern.rennecke@superh.com>

        * sh.h (REG_CLASS_HAS_FP_REG): New.
        (REGISTER_MOVE_COST) Use it.  Put body into a function and
        move it into:
        * sh.c (sh_register_move_cost).
        * sh-protos.h (sh_register_move_cost): Declare.

        * sh.c (sh_expand_builtin): Abort for unexpected nop values.
        (sh_adjust_cost): Always return a value.
