1 # Check that the dependence carrying step is not confused by
2 # a bound on the coefficient size.
3 # In particular, force the scheduler to move to a dependence carrying
4 # step by demanding outer coincidence and bound the size of
5 # the coefficients. Earlier versions of isl would take this
6 # bound into account while carrying dependences, breaking
7 # fundamental assumptions.
8 # On the other hand, the dependence carrying step now tries
9 # to prevent loop coalescing by default, so check that indeed
10 # no loop coalescing occurs by comparing the computed schedule
11 # to the expected non-coalescing schedule.
12 # OPTIONS: --schedule-outer-coincidence --schedule-max-coefficient=20
