That's a good idea. I'll include some form of visualization in the proposal.

To my knowledge, none of them are exposed as platform-agnostic
wrappers. Some of the operations directly correspond to a hardware
instruction. The mapping is explained in the Hardware Support section
of the proposal. I don't think that adding the intrinsic on top of
that adds any relevant information. Nevertheless, expanding the
introduction so that people get a better idea of these operations is
worthwhile.


Thanks for the feedback
