SSE4A and Advanced Bit Manipulation Intrinsics

The Visual C++ compiler makes the following Supplemental Streaming SIMD Extensions 4A (SSE4A) available. With all instrinsics, you must ensure that the underlying processor supports the instruction before you use it. Use the __cpuid instruction to determine what functionality your processor supports.

• _mm_extract_si64, _mm_extracti_si64

• _mm_insert_si64, _mm_inserti_si64

• _mm_stream_sd

• _mm_stream_ss

In addition, the following Advanced Bit Manipulation Intrinsics are available.

• __lzcnt16, __lzcnt, __lzcnt64

• __popcnt16, __popcnt, __popcnt64
