109If you notice errors in the align stuff, need more alignment for some ASM code
110for some CPU or need to use a function with less aligned data then send a mail
111to the ffmpeg-devel mailing list, ...
112
113!warning These alignments might not match reality, (missing attribute((align))
114stuff somewhere possible).
2cab6401 115I (Michael) did not check them, these are just the alignments which I think
7ce68923 116could be reached easily ...
