Meta-Tracing

Speed up your C interpreters with minimal code changes

JIT compilers are powerful, but retrofitting them into existing interpreters often feels like a monumental task. Laurence Tratt's presentation on yk, an open-source meta-tracing framework, challenges that assumption. He demonstrates how C-based language interpreters, like Lua and MicroPython, can be sped up automatically with minimal, non-invasive code changes. The focus on tracing loops and managing complex deoptimization is particularly compelling. It's a practical, grounded approach to a difficult problem.
