Abstract
An execution control method is described for use in a translator (19) which converts subject code (17) into target code (21). The translator (19) includes a translator trampoline function (191) which is called from a translator run loop (190) and which in turn calls either to a translator code generator (192) to generate target code, or else calls previously generated target code (212) for execution. Control then returns to the translator trampoline function (191) to make a new call, or returns to the translator run loop (190). Other aspects include making context switches through the trampoline function (191) and setting first and second calling conventions either side of the trampoline function (191). Jumping directly or indirectly between target code blocks (212) during execution is also described.
