PM46249: performance - Renaming arg of method triggers rebuild

APAR status

  • Closed as program error.

Error description

  • If you rename an argument of a method and rebuild, it recompiles
    
    everything that references the type in addition to the type. It
    should
    only need to recompile the single type since renaming an
    argument isn't
    a structural change.

    ****************************************************************
    Changes to the name of function parameters results in the
    compiler thinking that the part containing the function is
    structurally changed. Because of this, all parts that
    reference the function container will be recompiled. This
    can cause a performance problem.
    

Problem conclusion

  • Added code so that the compiler will no longer consider
    changes to function parameter names to be structurally
    significant.
