            Bug ID: 27175
           Summary: [Polly]  Explore new isl scheduler options
           Product: Polly
           Version: unspecified
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: Optimizer
          Assignee: polly-dev at googlegroups.com

    Classification: Unclassified

isl recently gained some new scheduler options, which seem to be worth
exploring.

On LNT we see for example currently an execution time regression for trmm.c in
Polybench due to isl choosing a bad schedule. These new scheduling options
might fix this.

We should experiment with these new options and reevaluate which ones we set by
default.
