Fold (x & 8) != 0 and (x & 8) == 8 into (x & 8) >> 3. This turns this PPC code: rlwinm r2, r3, 0, 28, 28 cmpwi cr7, r2, 8 mfcr r2 rlwinm r3, r2, 31, 31, 31 into this: rlwinm r2, r3, 0, 28, 28 srwi r2, r2, 3 rlwinm r3, r2, 0, 31, 31 Next up, nuking the extra and. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@21390 91177308-0d34-0410-b5e6-96231b3b80d8
