[PATCH] D109645: [LV] Recognize intrinsic min/max reductions

[Dave Green via Phabricator via llvm-commits]

dmgreen updated this revision to Diff 372229.
dmgreen added a comment.

On second thoughts, added checks to "llvm.vector.reduce.smax.v2i32" too, to show the reductions. Also added some "fmin/max without fast" reduction test cases, to show they are not vectorized.
