+// function pass registry (MachinePassRegistry) is auto filled by the static
+// constructors of MachinePassRegistryNode. Further there is a command line
+// parser (RegisterPassParser) which listens to each registry for additions
+// and deletions, so that the appropriate command option is updated.
