    Description

      Redundant test

      By the time the program execution reaches the test of this condition there is only one possible outcome for the test. The code at the destination of this branch is not dead, either because this condition is always true or because there is at least one other branch that reaches it. Test always evaluates the same
      /src/mongo/db/pipeline/pipeline_d.cpp:1186: DEADCODE 122327 At condition "mps", the value of "mps" cannot be "nullptr".
      /src/mongo/db/pipeline/pipeline_d.cpp:1186: DEADCODE 122327 Assigning: "mps" = "static_cast<mongo::MultiPlanStage *>(rootStage)".
      /src/mongo/db/pipeline/pipeline_d.cpp:1175: DEADCODE 122327 Condition "rootStage", taking true branch. Now the value of "rootStage" is not "nullptr".
      /src/mongo/db/pipeline/pipeline_d.cpp:1186: DEADCODE 122327 The condition "mps" must be true.
