Hi Michael,

the recent commit caused a failure:

/home/grosser/buildslave/polly-amd64-linux/llvm.src/tools/polly/test/DeLICM/reduction_overapproximate.ll:102:16:
error: expected string not found in input
; APPROX-NEXT: new: { Stmt_reduction_inc[i0, i1] -> MemRef_A[2] : i0 <=
3 and 0 <= i1 <= -2 + i0 };
               ^
<stdin>:62:2: note: scanning from here
 new: { Stmt_reduction_inc[i0, i1] -> MemRef_A[2] : 2 <= i0 <= 3 and 0
 <= i1 <= -2 + i0 };

I have no idea where it comes from. On my machine (and my earlier tests)
show no issues. Any ideas?

Best,
Tobias
