[Amy Huang via Phabricator via cfe-commits]

akhuang added inline comments.


================
Comment at: clang/lib/CodeGen/CodeGenFunction.cpp:908
     --EI;
     llvm::Value *Addr = Builder.CreateStructGEP(nullptr, &*EI, Idx);
     Addr = Builder.CreateAlignedLoad(Addr, getPointerAlign(), "agg.result");
