Abstract
A technique is provided for handling dynamically linked subject function calls arranged pass subject control flow to an intermediate control structure such as a procedure linkage table, then to subject linker code for modifying link information associated with the subject function calls during translation of subject code into target code in a dynamic binary translator. The subject code for execution on a subject processor is received by a translator, and corresponding target code for execution on the target processor is generated. The translator is arranged to build a function linkage table containing an entry giving the location of each function called by the subject code, so that code can be generated by the translator in which subject function calls are associated with code for performing the function, without generating target code corresponding to the intermediate control structure.
