[LLVMdev] [Openmp-dev] [RFC] OpenMP offload infrastructure (iteration 2)
Hi Sergey, Thanks for putting the new version of the document together! I don't see any other issues. I strongly believe the approach described in the document is a nice way to get OpenMP offloading support in clang. I plan to start actively contributing code for this component of the OpenMP implementation soon.

Just a head up, but it looks like OpenMP 4.1 will go away of the map of the
pointer as well as the pointee in maps...Since this is going away, we may
want to revisit the interface with this respect. It has not been voted in
yet, but we should know more in 2-3 weeks

Hi!
Here's an updated version - couple of misprints are fixed. Thank you
to Roel Jordans and Kelvin Li for pointing this out.
I put this on Google drive to avoid the mailing list restrictions,
feel free to complain on the accessibility issues.

Oh, and please - provide your positive feedback, if you don't see any
mistakes to be fixed. :)

Alex, Just to clarify my point, it may not be clear in my previous email. We currently have a prototype implementation in https://github.com/clang-omp that successfully uses the interface as described in the document. Of course, we should be flexible in adapting the interface and compiler to future changes in the OpenMP specification. But as the current spec, this design has shown to work well for several platforms. So I believe, this is a great starting point to get offloading working in clang and I am committed to actively work on this with everyone to make that happen. Thanks!
