           Summary: [Polly] Loops with possibly invariant base-address /

Test case

With Polly we do not optimize the attached test case as the array base
addresses are possibly loop-invariant. The same probably holds for the sizes of
the multi-dimensional arrays.

It might be interesting to hoist them out (conditionally) and then optimize
this loop nest anyhow.
