Re: [Haskell-cafe] Detecting extensions of the host processor

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 Henning Thielemann wrote:

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?
