Streaming SIMD Extensions (SSE)

Microsoft Specific

This section describes the C/C++ language-level features supporting SSE. The following features of the intrinsics are explained:

In addition, the following macro functions are described:

The header file xmmintrin.h contains the declarations for the SSE intrinsics. The file fvec.h contains operator overloads for some of the SSE intrinsics, which are available for use in C++ programs.

SSE intrinsics use the __m128, __m128i, and __m128d data types, which are not supported on Itanium Processor Family (IPF) processors. Any SSE intrinsics that use the __m64 data type are not supported on x64 processors.
