Abstract
Techniques for execution-driven loop splitting and load-safe code hosting are provided. Compiled code includes statements associated with an original loop and statements associated with an alternative loop. The alternative loop reproduces the original loop except for conditional load-safe invariant expressions that appeared in the original loop and that are separated out of the alternative loop. During processing, once the conditional load-safe invariant expressions are computed and referenced for a first time within the original loop, processing dynamically switches to the alternative loop where the conditional load-safe invariant expressions are computed outside of the alternative loop and referenced from within the alternative loop.
