I've been planning to improve `--offload` at some point. When using the OpenMP toolchain we have `-fopenmp-target=amdgcn-amd-amdhsa,nvptx64-nvidia-cuda` for example, which will just active those toolchains and default to whatever `nvptx-arch` and `amdgpu-arch` spit out. We can most likely use similar logic if needed. The OpenMP solution to target specific arguments is `-Xopenmp-target=amdgcn-amd-amdhsa -march=`, though that's not necessarily the best solution. https://github.com/llvm/llvm-project/pull/75357 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
