| # Check that the dependence carrying step is not confused by |
| # a bound on the coefficient size. |
| # In particular, force the scheduler to move to a dependence carrying |
| # step by demanding outer coincidence and bound the size of |
| # the coefficients. Earlier versions of isl would take this |
| # bound into account while carrying dependences, breaking |
| # fundamental assumptions. |
| # On the other hand, the dependence carrying step now tries |
| # to prevent loop coalescing by default, so check that indeed |
| # no loop coalescing occurs by comparing the computed schedule |
| # to the expected non-coalescing schedule. |
