[PATCH] D41953: [LoopUnroll] Unroll and Jam

Hi Dave,

Sorry, I don't follow you mean by splitting the pass manager. My idea of the problem and phase ordering would be: unroll and jam, as a standalone pass, runs before normal unrolling and, if successful, uses the metadata to prevent further unrolling later on. Can this not be the case? What am I missing here?

cheers,
sam
