[PATCH] D47735: [DAGCombiner] Create rotates more aggressively

[Krzysztof Parzyszek via Phabricator via llvm-commits]

kparzysz added a comment.

Changed `getIROrder` to `getNodeId`.

This patch uses `MatchRotate` to do the actual matching, so it's only going to look for opportunities to create a rotate.  Maybe that function should be replaced with MatchRotateOrFunnelShift in a future patch.
