James Almer	a039726c2a	avutil/x86/aes: remove a few branches ... The rounds value is constant and can be one of three hardcoded values, so instead of checking it on every loop, just split the function into three different implementations for each value. Before: aes_decrypt_128_aesni: 93.8 (47.58x) aes_decrypt_192_aesni: 106.9 (49.30x) aes_decrypt_256_aesni: 109.8 (56.50x) aes_encrypt_128_aesni: 93.2 (47.70x) aes_encrypt_192_aesni: 111.1 (48.36x) aes_encrypt_256_aesni: 113.6 (56.27x) After: aes_decrypt_128_aesni: 71.5 (63.31x) aes_decrypt_192_aesni: 96.8 (55.64x) aes_decrypt_256_aesni: 106.1 (58.51x) aes_encrypt_128_aesni: 81.3 (55.92x) aes_encrypt_192_aesni: 91.2 (59.78x) aes_encrypt_256_aesni: 109.0 (58.26x) Signed-off-by: James Almer <jamrial@gmail.com>	2025-04-10 12:02:34 -03:00
