class MachineSDNode

Declaration

class MachineSDNode : public SDNode { /* full declaration omitted */ };

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.
