[PATCH] D22377: [SCEV] trip count calculation for loops with unknown stride

[Reid Kleckner via llvm-commits]

You don't need any special options to reproduce, it should pick up the target from the .ll file. You could use bugpoint, but the test case is already pretty small, so I wouldn't bother. Run llc with -debug and try to figure out which pass is using SCEV to make bad choices. I would suspect LSR, which I think is a backend pass.
