[Openmp-commits] [PATCH] D77472: [OpenMP][PoC][WIP] An OpenMP-based OpenMP device runtime [NOT FOR COMMIT]

[Johannes Doerfert via Phabricator via Openmp-commits]

Herald added a project: OpenMP.

In order to make the device runtime truly device independent and thereby
reusable, e.g., for testing on the host, we want to eliminate the
remaining non-portable code. This basically boils down to __device__,
__shared__, and some other attributes, e.g., __forceinline__.

NOTE: This does not yet create a valid .bc file as the IR files we get
via c++ are not directly usable by llvm-link/opt/.... I did not
investigate how to extract the pure IR. The entire nvptx compilation
process should be re-investigated as we might not need to link.
