This patch uses 'Avoid_Non_Temporal_Memset' flag to access the non-temporal memset implementation for hygon processors. Test Results: hygon1 arch x86_memset_non_temporal_threshold = 8MB size new performance time / old performance time 1MB 0.994 4MB 0.996 8MB 0.670 16MB 0.343 32MB 0.355 hygon2 arch x86_memset_non_temporal_threshold = 8MB size new performance time / old performance time 1MB 1 4MB 1 8MB 1.312 16MB 0.822 32MB 0.830 hygon3 arch x86_memset_non_temporal_threshold = 8MB size new performance time / old performance time 1MB 1 4MB 0.990 8MB 0.737 16MB 0.390 32MB 0.401 For hygon arch with this patch, non-temporal stores can improve performance by 20% - 65%.
