For `STB_WEAK SHN_ABS` `__kcfi_typeid_*`, there is no duplicate definition error. Is this behavior intentional? Note: I don't think we should change lld to recognize some symbol prefix and enforce more rigid diagnostics. An error must be implemented with existing ELF features. ================ Comment at: clang/lib/CodeGen/CodeGenModule.cpp:2273-2275 + std::string Name = "__kcfi_typeid_" + F.getName().str(); + if (!allowKCFIIdentifier(Name)) + continue; ---------------- nickdesaulniers wrote: > You could probably avoid re-checking `"__kcfi_typeid_"` repeatedly? ``` if (const llvm::MDNode *MD = F.getMetadata(llvm::LLVMContext::MD_kcfi_type)) Type = ... else continue; ``` Repository: rG LLVM Github Monorepo CHANGES SINCE LAST ACTION https://reviews.llvm.org/D119296/new/ https://reviews.llvm.org/D119296 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
