[Haskell-cafe] Detecting extensions of the host processor

[Evgeny Tarasov]

If you use intel processor, you should call 'cpuid' assembler 
instruction to obtain this info.

Look at this document for the instruction semantics: 
http://www.intel.com/Assets/PDF/manual/253666.pdf

There is a wrapper for cpuid in haskell: 
http://hackage.haskell.org/package/cpuid
