18020 entry for overloaded function argument types RS6000_BTI_bool_V4SI
18021 andRS6000_BTI_bool_V4SI, mapping to P9V_BUILTIN_CMPNEB. Remove
18022 two entries mapping to P9V_BUITIN_CMPNED and one entry mapping to
18023 P9V_BUILTIN_CMPNEF to force use of instructions not specific to
18024 Power9 for implementations of vec_cmpne. Change the signature for
18025 all definitions of the overloaded P9V_BUILTIN_VEC_CMPNE_P function
18026 (representing vec_all_ne) to remove the previously described first
18027 argument of type RS6000_BTI_INTSI, as this was an artifact of
18028 reliance on the AltiVec predicate framework, which is no longer
18029 used in the implementation of these functions. Add
18030 P9V_BUILTIN_VEC_VCMPAE_P entries (representing the vec_anyeq
18031 function) to match all of the P9V_BUILTIN_VEC_VCMNE_P entries
18032 since, unlike the AltiVec predicate framework implementation, we
