Visual Studio 2010

Visual Studio 2012
Visual Studio 2008

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, __cpuidex 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
