Compilation of JavaScript to Wasm, Part 2: Ahead-of-Time vs. JIT
6.3 parsecs away

Travel
| | [AI summary] The article discusses the development of an Ahead-of-Time (AOT) compiler for JavaScript, leveraging precompiled inline-cache (IC) stubs. By moving runtime type binding to indirect calls, the compiler can generate static code, enabling full AOT compilation. This approach achieves significant performance improvements, with a 2.77x geometric mean speedup on various benchmarks. The article also explores further optimizations through profile-guided inlining, and compares this method with other AOT approaches like Hopc's type inference. The potential for future enhancements and the use of compiler backends derived from interpreters are also highlighted.
