x86 Intrinsics

The Visual C++ compiler makes the following intrinsics available on the x86 architecture.

In addition, the Visual C++ compiler supports intrinsics for MMX, Streaming SIMD Extensions (SSE), and Streaming SIMD Extensions 2 (SSE2). For more information, see MMX, SSE, and SSE2 Intrinsics. Also, many functions in the CRT are implemented as intrinsics on the x86 platform.
