On most targets, if a feature isn't available, the feature macro isn't defined at all. Defining it to 0 is unusual. If you need to do it this way for compatibility with existing code, I guess that's okay? https://github.com/llvm/llvm-project/pull/118008 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
