        * config/sh/sh.c (sh_lra_p): Make non-static.
        * config/sh/sh.md (addsi3): Use arith_reg_dest for operands[0] and
        arith_reg_operand for operands[1].  Remove TARGET_SHMEDIA case.
        Expand into addsi3_scr if operands[2] if needed.

        arith_reg_operand for operands[1].  Allow it only when LRA is enabled.
