[PATCH] D141105: [OpenMP] Add support for '--offload-arch=native' to OpenMP offloading

[Jon Chesterfield via Phabricator via cfe-commits]

JonChesterfield added a comment.

Possible naming hazard here. march=native means target the local processor architecture, zen2 or whatever, and we have the host CPU as an offloading target already. So what I'd expect this to do is host offloading with the openmp runtime compiled for the local variant of x86 or aarch64, not for it to have a guess at a GPU target.

What you think of offload-arch=GPU for pick a plausible GPU? That distinguishes it from other things we might want to offload to. Open question whether it should create a vgpu instance if it can't detect a physical card.
