``SDNode`` class. 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. For example, a combined div/rem operation will define
LLC command line options. 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.
