598 Let's consider below encoding of PRE_ barrier:
599    - get barrier type via RuntimeInterface: `BarrierType GetPreType() const`
600    - for this barrier type get all needed operands provided by Runtime via
603    - encode barrier code using loaded operands and pseudocode from `enum BarrierType`
