@efriedma-quic I've switched to `replaceInitializer`, thanks for suggestion! Now we construct `GV` with `nullptr` as initializer and `llvm::ConstantStruct::getTypeForElements(Fields)` as type, and then replace the initializer with `llvm::ConstantStruct::getAnon(Fields)`. See 55fc2c822f8f543d335e443a13860ae72fb5ce6d
