[PATCH] D138862: [Clang] Do not set offload kind in a freestanding build

tra added a comment. OK. So, we do need a flag, at least for now. I think we'll need a new one, because `-freestanding` will likely do a lot of things we don't actually want on the host side. How about `--offload-generic` or `--[no-]offload-runtime`. Repository: rG LLVM Github Monorepo CHA

JonChesterfield added a comment. Does this change the annotation on kernels compiled from C or C++ with -ffreestanding? If so, probably want a test showing the change. I have a vague idea that they pick up a default of 'opencl' at present, where 'none' is probably better. Or perhaps this is onl
