4895 entry for overloaded function argument types RS6000_BTI_bool_V4SI
4896 andRS6000_BTI_bool_V4SI, mapping to P9V_BUILTIN_CMPNEB. Remove
4897 two entries mapping to P9V_BUITIN_CMPNED and one entry mapping to
4898 P9V_BUILTIN_CMPNEF to force use of instructions not specific to
4899 Power9 for implementations of vec_cmpne. Change the signature for
4900 all definitions of the overloaded P9V_BUILTIN_VEC_CMPNE_P function
4901 (representing vec_all_ne) to remove the previously described first
4902 argument of type RS6000_BTI_INTSI, as this was an artifact of
4903 reliance on the AltiVec predicate framework, which is no longer
4904 used in the implementation of these functions. Add
4905 P9V_BUILTIN_VEC_VCMPAE_P entries (representing the vec_anyeq
4906 function) to match all of the P9V_BUILTIN_VEC_VCMNE_P entries

4908 do not share function descriptors between vec_alle and vec_anyeq.
