Please see how to use avx512XXX to distinguish: const wide_int_bitmask PTA_SKYLAKE_AVX512 = PTA_SKYLAKE | PTA_AVX512F const wide_int_bitmask PTA_CASCADELAKE = PTA_SKYLAKE_AVX512 | PTA_AVX512VNNI; const wide_int_bitmask PTA_CANNONLAKE = PTA_SKYLAKE | PTA_AVX512F const wide_int_bitmask PTA_ICELAKE_CLIENT = PTA_CANNONLAKE | PTA_AVX512VNNI const wide_int_bitmask PTA_ICELAKE_SERVER = PTA_ICELAKE_CLIENT | PTA_PCONFIG const wide_int_bitmask PTA_KNL = PTA_BROADWELL | PTA_AVX512PF | PTA_AVX512ER const wide_int_bitmask PTA_KNM = PTA_KNL | PTA_AVX5124VNNIW
