Yes, it was just local experiments, but I figured that it's accepted behavior in `nvcc` for the CUDA language so it might be reasonable to fold into `clang` on its own. The idea was that we can mark things like `_LIBCPP_HIDE_FROM_ABI` with CUDA specific things and inherit them, but this was required because those definitions are strongly redeclared. It's nothing that is an immediate *need* for a custom application, if that's what you're asking. https://github.com/llvm/llvm-project/pull/214911 _______________________________________________ cfe-commits mailing list [email protected] https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
