RyuJIT
RyuJIT is the just-in-time compiler used by the Microsoft .NET runtime, including CoreCLR, to translate Common Intermediate Language (CIL/IL) into native machine code at runtime. Implemented in C++, it is architecture‑aware and emits code for x86, x64, ARM32, and ARM64 targets. RyuJIT is the standard JIT for .NET Core and later .NET releases, replacing the older JIT used in legacy .NET Framework implementations for modern runtimes on Windows, Linux, and macOS.
It supports tiered compilation, starting with quick, less-optimized code to reduce startup time, followed by recompilation
RyuJIT is developed as part of the dotnet/runtime open-source project and is released under the project's open-source
Overall, RyuJIT aims to deliver balanced startup performance and steady high throughput across diverse workloads, with
