Will it be as bad as the generic implementation which does it byte per byte ?
I don't have any 64 bits target, can someone test it using the test app I have added in selftests ?
Or should I just leave it as is for 64 bits and just do the implementation for 32 bits until someone wants to try and do it for PPC64 ?
