> Hello, > > Patch in attach add SIMD for the 5 shuffle_bytes func for rgb2rgb > The new SIMD are write using external ASM. > > Also add checkasm test for theses func > Restricted to x86_64, because the scalar part doesn't compile on x86_32 > > I consider for the scalar part that the src_size value is a multiple of 4 > (because the shuffle is for 4 bytes) > > Pass fate test on X86_64 and X86_32 (os 10.12) > > > > > New patchs in attach : - Now compile on x86_32 and x86_64 - Add cosmetic patch to put all shuffle_bytes declaration in the same place Tested on X86_64 and X86_32 (os 10.12) Checkasm result : ./tests/checkasm/checkasm --test=sw_rgb --bench checkasm: using random seed 292997963 MMX: - sw_rgb.shuffle_bytes_2103 [OK] MMXEXT: - sw_rgb.shuffle_bytes_2103 [OK] SSSE3: - sw_rgb.shuffle_bytes_2103 [OK] - sw_rgb.shuffle_bytes_0321 [OK] - sw_rgb.shuffle_bytes_1230 [OK] - sw_rgb.shuffle_bytes_3012 [OK] - sw_rgb.shuffle_bytes_3210 [OK] AVX2: - sw_rgb.shuffle_bytes_2103 [OK] - sw_rgb.shuffle_bytes_0321 [OK] - sw_rgb.shuffle_bytes_1230 [OK] - sw_rgb.shuffle_bytes_3012 [OK] - sw_rgb.shuffle_bytes_3210 [OK] checkasm: all 12 tests passed shuffle_bytes_0321_c: 51.4 shuffle_bytes_0321_ssse3: 18.7 shuffle_bytes_0321_avx2: 12.7 shuffle_bytes_1230_c: 126.9 shuffle_bytes_1230_ssse3: 16.7 shuffle_bytes_1230_avx2: 12.9 shuffle_bytes_2103_c: 52.4 shuffle_bytes_2103_mmx: 76.7 shuffle_bytes_2103_mmxext: 197.2 shuffle_bytes_2103_ssse3: 17.4 shuffle_bytes_2103_avx2: 12.4 shuffle_bytes_3012_c: 127.4 shuffle_bytes_3012_ssse3: 14.7 shuffle_bytes_3012_avx2: 12.4 shuffle_bytes_3210_c: 127.4 shuffle_bytes_3210_ssse3: 18.2 shuffle_bytes_3210_avx2: 12.9 Martin
