-----------------------------------

             Summary: Faster bitwise operators
                 Key: IMPALA-5266
                 URL: https://issues.apache.org/jira/browse/IMPALA-5266
             Project: IMPALA
          Issue Type: Improvement
          Components: Backend
            Reporter: Zach Amsden
            Assignee: Zach Amsden


Bitwise operators could be sped up quite a bit.  In particular, round up to power of two is
not done efficiently, and population count can be done in hardware if ABM is supported.
