Abstract: The disclosure is related to optimizing generation of intermediate representation (IR) for a script code by eliminating redundant reference count code from the IR. The reference count code includes code that manages a reference count of an object, e.g., code that increments a reference count of the object (“incref code”) and an observer code which consumes or the execution of which depends on the reference count of the object. The IR is analyzed to identify redundant reference count code. Counters associated with the object are evaluated and upon satisfying the optimization criterion, the incref code is moved closer to the observer code. The incref code and the observer code that are adjacent to each other are identified as redundant code pair and the code pair is eliminated from the IR to generate an optimized IR. The optimized IR is further converted to an executable code.
