notes: |
  When code is loaded or modified, then most systems require synchronization
  instructions to update the instruction caches so that the loaded or modified
  code is fetched.  For example, systems with separate data and instruction
  caches or systems without instruction cache snooping.  The directives should
  be used by run time loader for example.
