Detailed Description
An SDNode that represents everything that will be needed to construct a MachineInstr.
These nodes are created during the instruction selection proper phase.
Note that the only supported way to set the memoperands is by calling the SelectionDAG::setNodeMemRefs function as the memory management happens inside the DAG rather than in the node.
