The Intel® C++ intrinsics listed in this section are designed for the IntelŪ PentiumŪ 4 processor with Streaming SIMD Extensions 3 (SSE3). They will not function correctly on other IA-32 processors. New SSE3 intrinsics include:
The prototypes for these intrinsics are in the pmmintrin.h header file.
You can also use the single ia32intrin.h header file for any IA-32 intrinsics.
