I am trying to use gcc vector extensions to speed up some of the operations
I am doing in my code. I am trying to use vector operations to generate xor
difference between memory regions. I am attaching what I have come up as
vec_diff.c. I am noticing there not much difference between timing of normal
operation when compared to using vector extensions. My belief is that I am
doing something wrong, any help on this is appreciated. I am not subscribed
to this list so would appreciate if I am copied in the reply.


Regards,
