What’s Inside TurboFan?
summary
TurboFan is presented as a unified compiler pipeline for JavaScript that introduces a new intermediate representation and backend to enable aggressive inlining and speculative feedback–driven optimizations. The talk details concrete optimization passes for property access, allocation elimination, and storage folding, describes measurement tools (trace-based benchmarks and a capture/replay suite), and shows real web workload results including a case study with about 1.65× runtime improvement and reduced memory pressure.
