             Summary: Proper codegen for TupleIsNullPredicate, IsNotEmptyPredicate and ValidTupleId
                 Key: IMPALA-7657
                 URL: https://issues.apache.org/jira/browse/IMPALA-7657
             Project: IMPALA
          Issue Type: Improvement
          Components: Backend
            Reporter: Tim Armstrong


These utility functions use GetCodegendComputeFnWrapper() to call the interpreted path but instead we could codegen them into efficient code. We could either use IRBuilder or, if possible, cross-compile the implementation and substitute in constants.
