Miscellaneous Instructions That Use Streaming SIMD Extensions

Microsoft Specific

The following table lists miscellaneous intrinsics and their descriptions.

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.

The header files xmmintrin.h and intrin.h contain the declarations for the SSE intrinsics.
