This section lists and describes the native intrinsics for ItaniumŪ instructions. These intrinsics cannot be used on the IA-32 architecture. The intrinsics for Itanium instructions give programmers access to Itanium instructions that cannot be generated using the standard constructs of the C and C++ languages.
The prototypes for these intrinsics are in the ia64intrin.h header file.
Itanium processor do not support SSE2 intrinsics. However, you can use the sse2mmx.h emulation pack to enable support for SSE2 instructions on Itanium architecture.
For information on how to use SSE intrinsics on Itanium architecture, see Using Streaming SIMD Extensions on Itanium(R) Architecture.
