Actually, I do think that the C compiler is doing a better job. On SiFive U74, the figures are horrible: By time: vp8_put_pixels4_c: 0.2 vp8_put_pixels4_rvi: 10.5 vp8_put_pixels8_c: 1.0 vp8_put_pixels8_rvi: 30.0 vp8_put_pixels16_c: 2.2 vp8_put_pixels16_rvi: 60.0 By cycles: vp8_put_pixels4_c: 84.0 vp8_put_pixels4_rvi: 3871.0 vp8_put_pixels8_c: 331.0 vp8_put_pixels8_rvi: 11281.2 vp8_put_pixels16_c: 826.0 vp8_put_pixels16_rvi: 22502.0 Best guess is that the data is not 64-bit aligned, otherwise I can't really make sense of those figures. -- Rémi Denis-Courmont http://www.remlab.net/ _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email ffmpeg-devel-requ...@ffmpeg.org with subject "unsubscribe".
