> Though maybe we proved that AMD really does implement all 32 comparisons correctly in AVX1/2? We are using 0xF to create all ones on AVX1 right?

Yes we proved that every AVX capable AMD machine (we tested Jaguar, Bulldozer, Excavator and Ryzen) correctly supported all comparison modes. Its the documentation that hasn't been fixed.
