        * config/rs6000/rs6000.c (rs6000_expand_unop_builtin): Return
        CONST0_RTX (mode) rather than const0_rtx where appropriate.
        (rs6000_expand_binop_builtin): Likewise.
        (rs6000_expand_ternop_builtin): Likewise; also add missing
        vsx_xxpermdi_* variants; also fix typo (arg1 => arg2) for
        vshasigma built-ins.
        * doc/extend.texi: Document that vec_xxpermdi's third argument
        must be a constant.
