In addition, all CRT functions in Intrinsics Available on All Architectures are enabled as intrinsics on the 64-bit Intel architecture, as well as the following additional CRT function:

_setjmpex

Also, many MMX, Streaming SIMD Extensions (SSE), and Streaming SIMD Extensions 2 (SSE2) intrinsics are also available on the Intel 64-bit architecture.
