Benjamin Kramer d822892455 Add a DAGCombine to turn (ctpop x) u< 2 into (x & x-1) == 0. ... This shaves off 4 popcounts from the hacked 186.crafty source. This is enabled even when a native popcount instruction is available. The combined code is one operation longer but it should be faster nevertheless. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@123621 91177308-0d34-0410-b5e6-96231b3b80d8		2011-01-17 12:04:57 +00:00
