   8 /* Information about a band within a schedule.
   9  *
  10  * n is the number of scheduling dimensions within the band.
  11  * coincident is an array of length n, indicating whether a scheduling dimension
  12  *      satisfies the coincidence constraints in the sense that
  13  *      the corresponding dependence distances are zero.
  14  * permutable is set if the band is permutable.
  15  * mupa is the partial schedule corresponding to this band.  The dimension
  16  *      of mupa is equal to n.
  17  * loop_type contains the loop AST generation types for the members
  18  * in the band.  It may be NULL, if all members are
  19  * of type isl_ast_loop_default.
  20  * ast_build_options are the remaining AST build options associated
  21  * to the band.
