David Majnemer 891ec6d69f InstSimplify: shl nsw/nuw undef, %V -> undef ... We can always choose an value for undef which might cause %V to shift out an important bit except for one case, when %V is zero. However, shl behaves like an identity function when the right hand side is zero. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@224405 91177308-0d34-0410-b5e6-96231b3b80d8		2014-12-17 01:54:33 +00:00
