Unfortunately `llvm::SubtargetFeatureKV` doesn't hold a lot of information and semantics of its contents is even less clear the what's capture here. I'll add a comment to this block clarifying what's being captured. https://github.com/llvm/llvm-project/pull/95805 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
