This book lists and describes the native intrinsics for Itanium(TM) 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 intrinsics for Itanium instruction prototypes can be found in the ia64intrin.h header file.
