Hello,
I've seen on doom9 a thread a so called "AMD optimized" build that was
supposed to give very large improvement over Koepi's builds just
replacing the libc memcpy with the AMD copyrighted one.
I know that we use memcpy in very few places (mostly setedges) but i was
curious to confirm or refute the results given by users so i ported the
well known xine memcpy functions to nasm.
The results are much more close to what i expected: ie very small
improvement (<1%), far from the 10% advertised by the "AMD optimized"
build users.
Do you think it's worth commiting this code ?
