4x Faster Interpreters? The Meta-Tracing Secret EXPOSED

Why watch

Laurence Tratt demonstrates yk, a meta-tracing framework that automatically adds JIT compilation to C-based interpreters like Lua, achieving up to 4x performance gains with under 500 lines of code changes. The talk covers how ykllvm serializes interpreter IR, handles deoptimization and shadow stacks, and compares against PyPy and Truffle approaches. Ideal for senior developers and architects working on interpreter performance or language implementation.
