Deoptless: Speculation with Dispatched On-Stack Replacement and Specialized Continuations

Autor: Flückiger, Olivier, Ječmen, Jan, Krynski, Sebastián, Vitek, Jan

Publikováno v: 43rd ACM SIGPLAN International Conference on Programming Language Design and Implementation (PLDI 2022)

Just-in-time compilation provides significant performance improvements for programs written in dynamic languages. These benefits come from the ability of the compiler to speculate about likely cases and generate optimized code for these. Unavoidably,

Sampling Optimized Code for Type Feedback

Autor: Flückiger, Olivier, Wälchli, Andreas, Krynski, Sebastián, Vitek, Jan

Publikováno v: Proceedings of the 16th ACM SIGPLAN International Symposium on Dynamic Languages (DLS 2020)

To efficiently execute dynamically typed languages, many language implementations have adopted a two-tier architecture. The first tier aims for low-latency startup times and collects dynamic profiles, such as the dynamic types of variables. The secon

R Melts Brains -- An IR for First-Class Environments and Lazy Effectful Arguments

Autor: Flückiger, Olivier, Chari, Guido, Ječmen, Jan, Yee, Ming-Ho, Hain, Jakob, Vitek, Jan

Publikováno v: Proceedings of the 15th ACM SIGPLAN International Symposium on Dynamic Languages (DLS 2019)

The R programming language combines a number of features considered hard to analyze and implement efficiently: dynamic typing, reflection, lazy evaluation, vectorized primitive types, first-class closures, and extensive use of native code. Additional

Correctness of Speculative Optimizations with Dynamic Deoptimization

Autor: Flückiger, Olivier, Scherer, Gabriel, Yee, Ming-Ho, Goel, Aviral, Ahmed, Amal, Vitek, Jan

Publikováno v: Proceedings of the ACM on Programming Languages (POPL 2018)

High-performance dynamic language implementations make heavy use of speculative optimizations to achieve speeds close to statically compiled languages. These optimizations are typically performed by a just-in-time compiler that generates code under a
