[cfe-dev] [RFC] Add SYCL programming model support.

[Bader, Alexey via cfe-dev]

Hi Richard, John,

Thank you for the feedback.
We have a long term plan to support SYCL and we are willing collaborate with the community on building unified infrastructure for SYCL.
I'll make sure that contributors working with CUDA, OpenMP, OpenCL and alternative SYCL implementations are involved in review process as you suggested.

Thanks,
Alexey

Right.  As long as Intel understands that this isn't a one-shot project and will require ongoing maintenance even after being feature-complete, and as long as you're willing to cooperate with contributors with similar projects to try to build a good common infrastructure, I have no objection to taking this into Clang.

If this is a single-source language, then you may also find it helpful to coordinate with the contributors who've worked on OpenMP and CUDA.

John.
