Combining the two allows the predication aspect to be merged and shared, making for better packing. These changes occur on a precise schedule: compilers should not have difficulties statically allocating the Context Propagation, as long as certain conventions are followed, such as avoidance of allowing the context to propagate through branches used by more than one incoming path, and variable-length loops. -- 2.30.2
