here are the cmpps numbers, because it makes asm tedious to read without them.
//0 = (==) //4 = (!=) //5 = (>=) //2 = (<=) //6 = (>) //1 = (<)
copy paste
btw what is 3?

I made that exact list a while back and had a look at it. Also missing the 3
No idea. havnt tried it either but couldnt it simply be tested by running some numbers thru?

3 makes an unordered comparison. In logical term the relation is (xmm1 ? xmm2)

So is there any kind of use for that?
If there is can you provide an example?

not so easy to find anything that explains it in an understandable way. atleast here is some description about "unordered comparision" but with another command: http://www.rz.uni-karlsruhe.de/rz/docs/ ... /vc315.htm looks like it can do checks for qnan and other invalid stuff.

Yep, my understanding is that if you expect a result to be NaN you can check it this way and throw your own exception (or handle it in a different way).
