Interesting stuff Jason - I will have to look at the mod_1_2 code to see
what might be different about it.

Darn, I already did the conversion :-(
I don't have enough registers to use only the 32-bit registers so I have to
put stuff in r8 and r9 instead. Given this involved prefix opcodes, I am
wondering what I should o with your coded nops since any alignment you are
seeking won't be the same wit

Hi
New karasub/add for nehalem , I did do a re-shuffle and it was pretty much
optimal , but the feedin/winddown code killed it , so at the mo this is just
the existing K10 code with the inc's replaced by an add and lea's , just do a
diff.
Going to a 3-way unroll on karasub free's up 2 registers

Hi
Heres the first lot of new assembler code for the x64 (in trunk)
popcount/hamdist are not terribly useful for MPIR , but they do offer a simple
way to practice stuff.
K8 popcount was 5.5c/l with 2way unroll now 4.66c/l with 3way
K8 hamdist was 5.5c/l with 2way unroll now 5.0c/l with 3way
