Overview: Intrinsics for IA-64 Instructions

This section lists and describes the native intrinsics for IA-64 instructions. These intrinsics cannot be used on the IA-32 architecture. These intrinsics give programmers access to IA-64 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.

The Intel® Itanium® processor does not support SSE2 intrinsics. However, you can use the sse2mmx.h emulation pack to enable support for SSE2 instructions on IA-64 architecture.

For information on how to use SSE intrinsics on IA-64 architecture, see Using Streaming SIMD Extensions on IA-64 Architecture.
