Exiting Through the YJIT - Tracing Side-Exits in Ruby Optimization - RubyConf 2022

Explore the intricacies of optimizing code for the YJIT compiler in this RubyConf 2022 talk by Eileen M Uchitelle. Discover the challenges of identifying code exits and their causes, and learn about the development of a tool designed to reveal the exact lines triggering exits. Delve into the concept of side-exits and the process of building a tracer for them. Follow the journey from the original implementation to its rewrite in Rust, and understand the importance of continuously improving upon one's work. Gain valuable insights into YJIT compiler optimization techniques and the iterative nature of software development in this informative 29-minute presentation.
