   8 # This test contains eight global pointers with different signing schemes
   9 # (IA vs DA key, with and without address diversity, and with 0 or 0xa5a5 as
  10 # the additional diversity value). If all pointers pass authentication at
  11 # runtime then the test returns zero.
  12 #
  13 # This test requires execution since the signed pointers are written by a
  14 # signing function attached to the graph.
  15 #
  16 # TODO: Write an out-of-process version. This will probably need to be added to
  17 # the ORC runtime.
