[LLVMdev] Lower action for SelectionDAG node with multiple operands?

For each combination of the target independent SelectionDAG operation and
data type, an action (one of Legal, Promote, Expand and Custom) can be
specified. In this case, how to handle the combination of one SelectionDAG
node with multiple data types as its operands?

Cheers
