            Bug ID: 33807
           Summary: [Polly] Importing schedules and memory access updates
                    that change the dependences not possible
           Product: Polly
           Version: unspecified
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: Optimizer

Traditionally we only allowed schedules and memory access relations to be
imported which do not change the data dependences. However, with DeLICM it now
becomes possible to perform transformations that enable more freedom in the
data dependences. We should probably teach the jscop import to only check for
RAW dependences and to also take the possibly updated memory accesses into
account.
