[LLVMdev] [cfe-dev] [Openmp-dev] [RFC] OpenMP offload infrastructure (iteration 2)

Hi Alex,

At the OpenMP review telecon we agreed in going in there and say that the
approach is great and we support that, so we can then go ahead and start
implementing it, regardless of how it is going to look like at the end. We
can still change the interface and compiler as the time goes by if need to.

Regards,
Samuel

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 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.


Thanks again,
Samuel

  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. :)
