-; The following tests contain loops for which SCEV cannot determine the backedge
-; taken count. This is because the backedge taken condition is produced by an
-; icmp with one of the sides being a loop varying non-AddRec expression.
-; However, there is a possibility to normalize this to an AddRec expression
-; using SCEV predicates. This allows us to compute a 'guarded' backedge count.
-; The Loop Vectorizer is able to version to loop in order to use this guarded
-; backedge count and vectorize more loops.
