anujphadke has uploaded a new patch set (#2). Change subject: IMPALA-3897 Codegen null-aware constant in PHJ::ProcessBuildBatch() ......................................................................
IMPALA-3897 Codegen null-aware constant in PHJ::ProcessBuildBatch() This change codegen outs a branch in ProcessBuildBatch(). This branch never gets executed for most of the join types except NULL_AWARE_LEFT_ANTI_JOIN. The branch itself is not expensive to execute, but it will reduce codegen time by removing the dead code inside the branch for almost all join modes.
