// This file contains the mechanics for machine function pass registries. A
// 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.
