[LLVMdev] legalize dag problem
thanks for the help ..I do add the chain and the result.
My code is like this ...
SDValue Ops[] = { load->getChain(), load->getOperand(1),
load->getBasePtr(), des };
DAG.getNode(CustomOpc, NodeTys, Ops, 4);
thanks again!

Looks like you lowered the load improperly. It should return 2 values:
the value loaded and a chain.

[LLVMdev] legalize dag problem
Hi
I am running into a legalize dag issue after custom lowering a
load. If someone can give me pointers that would be great. I am using
llvm 2.6
When custom lowering a load, the following code gets executed.
Tmp1 = TLI.LowerOperation(Tmp3, DAG);
if (Tmp1.getNode()) {
Tmp3 = LegalizeOp(Tmp1);
Tmp4 = LegalizeOp(Tmp1.getValue(1)); <----------------- what
