...is means that the optimizer has to be aware of it, I’m missing the magic here?
I understand that an openmp specific optimization can do it, the question is how it an openmp agnostic supposed to behave in face of llvm.experimental.intrinsic_a?

Hi Sanjoy,
Yes, that's exactly what we have been looking at recently here, but the region tags seem to make it possible to express the control flow as well, so I think we could start with reg ions+metadata, as Hal and Xinmin proposed, and then figure out what needs to be first class instructions.
