[PATCH] D104058: ThinLTO: Fix inline assembly references to static functions with CFI

[Nick Desaulniers via Phabricator via cfe-commits]

nickdesaulniers added inline comments.


================
Comment at: llvm/lib/Transforms/IPO/ThinLTOBitcodeWriter.cpp:58-80
+    std::string OldName = Name.str();
     std::string NewName = (Name + ModuleId).str();
 
     if (const auto *C = ExportGV.getComdat())
       if (C->getName() == Name)
         RenamedComdats.try_emplace(C, ExportM.getOrInsertComdat(NewName));
 
----------------
Can you avoid making a copy of the OldName by doing the `appendToCompilerUsed` BEFORE making the dangling reference via `ExportGV.setName(NewName);`?
