[PATCH] D154036: [libc] Add support for creating wrapper headers for offloading in clang

[Joseph Huber via Phabricator via cfe-commits]

jhuber6 updated this revision to Diff 537787.
jhuber6 added a comment.

Changing this to only apply to OpenMP for now. It breaks CUDA / HIP builds
because they already have forward declarations of things like `malloc` or
`memcpy` on the GPU that conflict. We'll need to clean those up later.
