This all looks correct, though I wonder do you really need to check all those AVX512 flags in each case? Since "F" is always present in any AVX512 implementation perhaps it can be checked, though if the other three always need to be checked I can understand if you want to keep it there for completeness. [Are all the other 3 used in your code?] Acked-by: Bruce Richardson <bruce.richard...@intel.com>
