but the code is not cleanly split currently, we do in some cases not have
x86-asm, ppc-asm and C functions doing the same. so moving each asm in its own
function will not provide you with 3 sets of functions that are
interchangeable.
I really think its a extreemly bad idea to move asm code around before you
have any system in place to switch between things (that is no dsputil context
no global function ptrs, nothing)

Frequently ignored awnser#1 FFmpeg bugs should be sent to our bugtracker. User
questions about the command line tools should be sent to the ffmpeg-user ML.
And questions about how to use libav* should be sent to the libav-user ML.
