[PATCH] D26277: [SLP] Fixed cost model for horizontal reduction.

[Michael Kuperstein via llvm-commits]

mkuper added a comment.

So, now, none of the costs on the tests actually change?
Does that mean that the changes in costs in the previous versions came from the +1?

Can you add a test that demonstrates the cost change? (Preferably in a way that shows what happened - e.g. commit a test with the "bad" cost, and then have a diff with the good one).
