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

_setjmpex	inp	_inp
inpd	_inpd	inpw
_inpw	outp	_outp
outpd	_outpd	outpw
_outpw

In addition, many MMX, Streaming SIMD Extensions (SSE), and Streaming SIMD Extensions 2 (SSE2) intrinsics are available on the AMD 64-bit platform.
