Correctness of Speculative Optimizations with Dynamic Deoptimization

Participant : Gabriel Scherer.

This joint work with Olivier Flückiger, Ming-Ho Yee Ming-Ho, Aviral Goel, Amal Ahmed and Jan Vitek was initiated during Gabriel Scherer's post-doctoral stay at Northeastern University, Boston, USA.

Practitioners from the software industry find it difficult to implement Just-In-Time (JIT) compilers for dynamic programming languages, such as Javascript: they don't know how to reason on the correctness of their optimizations in the context of Just-In-Time code generation and deoptimization. We explain how to adapt reasoning approaches and proof techniques from standard compiler research to this new setting.

This work [14] will appear in POPL 2018.
