[Openmp-commits] [PATCH] D97004: [OpenMP][NVPTX] Add the support for CUDA 11.2 and CUDA 11.1

[Shilei Tian via Phabricator via Openmp-commits]

tianshilei1992 updated this revision to Diff 324797.
tianshilei1992 added a comment.

Use PTX 71 for CUDA 11.2 although it supports PTX 72 because seems like Clang
cannot support PTX 72 every well.
