1. A computer apparatus comprising: a target processor; and a translator arranged to receive subject code for execution on a subject processor and generate target code for execution on the target processor, the translator comprising: a function linkage table; and logic for: detecting a modification to a procedure linkage table associated with a dynamically linked subject function call of the subject code; associating the dynamically linked subject function call with code for performing the dynamically linked subject function call; and adding, in response to the detecting of the modification, an entry to the function linkage table, the entry comprising: an identifier corresponding to the dynamically linked subject function call; and a location of the code for performing the dynamically linked subject function call.
