Abstract

The inventive method for dynamically converting and carrying out an object code provides for the optimization of the control flow between the individually translated object code blocks, thereby reducing the calls of a run-time system (distributor) during execution of the translated object code. To this end, returns to the distributor are replaced as widely as possible by direct returns to a return target in the translated object code. This replacement converts run-time calculations to calculations regarding compilation time, thereby improving the run-time efficiency of the translated code.
