7169 entry for overloaded function argument types RS6000_BTI_bool_V4SI
7170 andRS6000_BTI_bool_V4SI, mapping to P9V_BUILTIN_CMPNEB. Remove
7171 two entries mapping to P9V_BUITIN_CMPNED and one entry mapping to
7172 P9V_BUILTIN_CMPNEF to force use of instructions not specific to
7173 Power9 for implementations of vec_cmpne. Change the signature for
7174 all definitions of the overloaded P9V_BUILTIN_VEC_CMPNE_P function
7175 (representing vec_all_ne) to remove the previously described first
7176 argument of type RS6000_BTI_INTSI, as this was an artifact of
7177 reliance on the AltiVec predicate framework, which is no longer
7178 used in the implementation of these functions. Add
7179 P9V_BUILTIN_VEC_VCMPAE_P entries (representing the vec_anyeq
7180 function) to match all of the P9V_BUILTIN_VEC_VCMNE_P entries
7181 since, unlike the AltiVec predicate framework implementation, we
7182 do not share function descriptors between vec_alle and vec_anyeq.
7183 (altivec_resolve_overloaded_builtin): Add SFmode and DFmode to the
7184 set of modes that receive special treatment even when
7185 TARGET_P9_VECTOR is true. The special treatment emits code that
7186 does not depend on Power9 instructions.
