Your hand assembly version looked extreamly fast while the new c code version does not seem very fast in comparison. Does the hand assembly work? Regardless, there is lots to work with now. Thanks.


Not quite sure about x64 addressing modes in ML64 - RIP/EIP-relative? It should not be to hard to link it with C-code, considering calling conventions, scratch register usage etc.. Despite it's nice possible parallel computation of four independent chains, i still don't believe it may be faster than kindergarten-rookattacks, but i may be wrong.

How many cycles does it take to load one 64-bit cacheline (8 cacheline aligned bitboards) from L1 into eight general purpose registers on a core 2 duo?
