Henrik Gramner	f0b7882ceb	x86inc: Drop SECTION_TEXT macro The .text section is already 16-byte aligned by default on all supported platforms so `SECTION_TEXT` isn't any different from `SECTION .text`.	10 years ago
Clément Bœsch	554d819062	avutil/pixelutils: faster pixelutils_sad_16x16 501 to 439 decicycles. See `45c7f3997e`.	10 years ago
Clément Bœsch	45c7f3997e	avutil/pixelutils: faster pixelutils_sad_[au]_16x16 ~560 → ~500 decicycles This is following the comments from Michael in https://ffmpeg.org/pipermail/ffmpeg-devel/2014-August/160599.html Using 2 registers for accumulator didn't help. On the other hand, some re-ordering between the movs and psadbw allowed going ~538 to ~500.	10 years ago
