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:

I like to detect at runtime whether the processor my program runs on
has certain extensions (SSE2, SSE3 or so) in order to execute
optimized code. On Linux I can process the contents of /proc/cpuinfo
but this will not work on Windows. Is there a portable way in Haskell?
