Abstract

In one example a processor includes a region formation engine to identify a region of code for translation from a guest instruction set architecture to a native instruction set architecture. The processor also includes a binary translator to translate the region of code. The region formation engine is to perform aggressive region formation, which includes forming a region across a boundary of a return instruction. The translated region of code is to prevent a side entry into the translated region of code at a translated return target instruction included in the translated region of code. In more specific examples, performing aggressive region formation includes a region formation grow phase and a region formation cleanup phase. In the grow phase priority may be given to growing complete paths from a call target to a corresponding return. The region formation cleanup phase may comprise eliminating call targets that are not reachable.
