I take it more of a hint than strictly necessary like it is in OpenCL, like saying a pointer is restrict in C. I was surprised that it cut down like 10 SGPRs on an OpenMP kernel using it. The other motivation was allowing this to be used to link to an OpenCL program that does not have generic pointers. Thanks.
