Architecting High-Performance JIT Compilation in the GraalVM Polyglot Runtime
GraalVM’s tiered JIT adapts compilation based on runtime profiles. Polyglot programs see up to 3x speedups.

Inside Cranelift: How a Baseline JIT Compiler Optimizes WebAssembly for Production Workloads
Cranelift is the baseline JIT that powers Wasmtime and Fastly’s edge platform. Here is how it compiles WebAssembly quickly, what optimizations matter at the baseline tier, and where it fits next to LLVM and TurboFan.
Inside the V8 TurboFan Compiler: How Speculative JIT Compilation Really Works
How TurboFan turns hot JavaScript into optimized machine code using speculation, Sea of Nodes IR, and feedback-driven inlining — and why it has to bail out so often.
Inside the QBE JIT compiler: register allocation and inline caching in practice
How QBE compiles SSA IR to machine code, with a close look at its linear-scan register allocator and the inline caching techniques production JITs use to recover lost megamorphic performance.
