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 | |
