  11  * "start" and "end" are file offsets of the corresponding program text.

  13  * "domain" is the union of all iteration domains.
  14  * "call" contains the iteration domains of statements with a call expression.
  15  * "reads" contains all read accesses.
  16  * "live_in" contains read accesses that have no corresponding
  17  *      writes in the scop.
  18  * "writes" contains all write accesses.
  19  * "kills" contains all kill accesses.
  20  * "dep_flow" represents the flow dependences.

  22  * "schedule" represents the (original) schedule.
  23  *
  24  * "arrays" and "stmts" are copies of the corresponding elements
  25  * of the original pet_scop.
