1023 RS6000_BTI_bool_V16QI. Remove erroneous ALTIVEC_BUILTIN_VEC_CMPNE
1024 entry for overloaded function argument types RS6000_BTI_bool_V4SI
1025 andRS6000_BTI_bool_V4SI, mapping to P9V_BUILTIN_CMPNEB. Remove
1026 two entries mapping to P9V_BUITIN_CMPNED and one entry mapping to
1027 P9V_BUILTIN_CMPNEF to force use of instructions not specific to
1028 Power9 for implementations of vec_cmpne. Change the signature for
1029 all definitions of the overloaded P9V_BUILTIN_VEC_CMPNE_P function
1030 (representing vec_all_ne) to remove the previously described first
1031 argument of type RS6000_BTI_INTSI, as this was an artifact of
1032 reliance on the AltiVec predicate framework, which is no longer
1033 used in the implementation of these functions. Add
1034 P9V_BUILTIN_VEC_VCMPAE_P entries (representing the vec_anyeq
1035 function) to match all of the P9V_BUILTIN_VEC_VCMNE_P entries
1036 since, unlike the AltiVec predicate framework implementation, we
1037 do not share function descriptors between vec_alle and vec_anyeq.
1038 (altivec_resolve_overloaded_builtin): Add SFmode and DFmode to the

1040 TARGET_P9_VECTOR is true. The special treatment emits code that
