Meta-tracing Interpreters in WebAssembly

Explore a 24-minute presentation from the WAW 2025 workshop where researchers Andrew Brown and Andrew Tolmach from Portland State University discuss their work-in-progress on developing a meta-tracing JIT compiler for WebAssembly. Learn about their innovative framework that improves interpreted program performance within WebAssembly by combining independent tools that capture WebAssembly traces, identify loops in user programs, reconstruct optimized trace fragments, and transfer control via on-stack replacement. This technical talk, sponsored by ACM SIGPLAN, was presented on January 20, 2025, as part of the POPL25 conference.
