As I read the

...Ops.push_back(DAG.getConstant(1, MVT::i32)); Chain = DAG.getNode(ISD::ADD, DAG.getVTList(MVT::Other, MVT::i32), &Ops[0], Ops.size()); Isn't that the way how it is supposed to work?

Thank you for your help. I think I managed to create the instruction I wanted: // mov eax, 41 Chain = DAG.getCopyToReg(Chain, DAG.getRegister(X86::EAX, MVT::i32), DAG.getConstant(41, MVT::i32), InFlag); InFlag = Chain.getValue(1); I don't understand though what InFlag is for. As I read the code, it even remains uninitialized when first passed to some node creation method.
