Now that HIVE-5771 is committed, we should remove any vectorization related code which duplicates this feature. For example, a fn to be cleaned is VectorizarionContext::foldConstantsForUnaryExprs(). In addition to this change, constant propagation should kick in when vectorization is enabled. i.e. we need to lift the HIVE_VECTORIZATION_ENABLED restriction inside ConstantPropagate::transform(). -- This message was sent by Atlassian JIRA (v6.2#6252)
