David Majnemer 49c14f54b2 InstSimplify: Exact shifts of X by Y are X if X has the lsb set ... Exact shifts may not shift out any non-zero bits. Use computeKnownBits to determine when this occurs and just return the left hand side. This fixes PR21477. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@221325 91177308-0d34-0410-b5e6-96231b3b80d8		2014-11-05 00:59:59 +00:00
