The primary payload of the ``SDNode`` is its operation code (Opcode) that indicates what operation the node performs and the operands to the operation. The various operation node types are described at the top of the -``include/llvm/CodeGen/SelectionDAGNodes.h`` file. +``include/llvm/CodeGen/ISDOpcodes.h`` file. Although most operations define a single value, each node in the graph may define multiple values.

The following options pop up a window displaying the SelectionDAG at specific times (if you only get errors printed to the console while using this, you probably `need to configure your -system <ProgrammersManual.html#ViewGraph>`_ to add support for it). +system <ProgrammersManual.html#viewing-graphs-while-debugging-code>`_ to add support for it). * ``-view-dag-combine1-dags`` displays the DAG after being built, before the first optimization pass. |
