[LLVMdev] LowerCALL (TargetLowering)

[Nikhil Patil]

Aah, I figured this out now. I had misunderstood the semantics of the
getNode operator. The following code snippet now works.

Sorry for the noise! :)

	Tys.push_back(MVT::Other);
	Ops.push_back(Chain);
	for (unsigned i = 0; i != NumOps; ++i) {
	    SDOperand Arg = Op.getOperand(5+2*i);
	    Tys.push_back(Arg.getValueType());
	    Ops.push_back(Arg);
	}
	
	Chain = DAG.getNode(opcode, RetVT, &Ops[0], Ops.size());
	
	assert(RetVT == MVT::Other);
	return Chain;

(as opposed to the earlier:)
