David Majnemer 53fc39992d InstCombine: Fold X-C1 <u 2 -> (X & -2) == C1 ... Back in r179493 we determined that two transforms collided with each other. The fix back then was to reorder the transforms so that the preferred transform would give it a try and then we would try the secondary transform. However, it was noted that the best approach would canonicalize one transform into the other, removing the collision and allowing us to optimize IR given to us in that form. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@185808 91177308-0d34-0410-b5e6-96231b3b80d8		2013-07-08 11:53:08 +00:00
