Streaming SIMD Extensions 2 Intrinsics Implementation

Streaming SIMD Extensions 2 operate on 128-bit quantities with 64-bit double precision floating-point values. The IntelŪ ItaniumŪ processor does not support parallel double precision computation, so Streaming SIMD Extensions 2 are not implemented on Itanium-based systems.
