[llvm-dev] [RFC] Proposed interplay of Clang & Flang & LLVM wrt. OpenMP [@Flang-dev]

[Doerfert, Johannes via llvm-dev]

Hi,

[I started this discussion on a single mailing list (flang-dev [0]) but
 this is a notice to the others (llvm, clang, openmp) so we hopefully
 get all interested parties involved.]

This is an RFC for the design of the OpenMP front-ends under the LLVM
umbrella. It is necessary to talk about this now as Flang (aka. F18) is
maturing at a very promising rate and about to become a sub-project next
to Clang.

TLDR;
Keep AST nodes and Sema separated but unify LLVM-IR generation for
OpenMP constructs based on the (almost) identical OpenMP directive
level.

For more information and to participate in the discussion, please see
the flang-dev post [0].

Thanks,
  Johannes
