38/* minimum alignment rules ;)
39 * If you notice errors in the align stuff, need more alignment for some ASM code
40 * for some CPU or need to use a function with less aligned data then send a mail
41 * to the ffmpeg-devel mailing list, ...
42 *
43 * !warning These alignments might not match reality, (missing attribute((align))
44 * stuff somewhere possible).
45 * I (Michael) did not check them, these are just the alignments which I think
46 * could be reached easily ...
47 *
48 * !future video codecs might need functions with less strict alignment
