3660         (VCMPAE_P): Add BU_P9V_OVERLOAD_2 macro to change implementation
3661         of vec_any_eq to not use AltiVec predicate framework.

3674         all definitions of the overloaded P9V_BUILTIN_VEC_CMPNE_P function
3675         (representing vec_all_ne) to remove the previously described first
3676         argument of type RS6000_BTI_INTSI, as this was an artifact of

3702         (*vsx_ne_<mode>_p): For modes VSX_F (V4SF and V2DF), remove this
3703         define_insn pattern because the xvcmpne<VSs>. instruction is not
3704         supported.
