Intrinsics - cant find <ia64intrin.h> but have <ia32intrin.h>?

Question

Whilst looking at the Intel Intrinsics pdf (to try and work out which headers need to be included) I can see that there is <ia64intrin.h> header. However, I only seem to have <ia32intrin.h> available.

What do I need to do to setup the ability to use all Intel intrinsics features? I have the Intel C/C++ compiler....

Answer 1

Do try to focus on the intrinsics that are supported by the specific processor you want to target. That is pretty unlikely to be an Itanium these days. So unusual that it isn't included anymore, the Itanium compiler is a separate download.
