MIR is a lightweight JIT compiler project built around a strongly typed Medium Internal Representation, with a C11 JIT compiler and interpreter included. It is designed as a foundation for implementing fast, lightweight JITs for dynamic languages such as Ruby.

Use cases

• build a lightweight JIT compiler for a dynamic language
• compile and run C code at runtime with a JIT
• embed an interpreter with JIT capabilities in a language runtime
• experiment with intermediate representations for code generation
• generate machine code for x86-64, aarch64, ppc64, s390x, or riscv64

When to choose

• you need a small, embeddable JIT rather than a heavyweight VM like LLVM
• you are building a JIT for a scripting language like Ruby or MRuby
• you want to JIT-compile C code at runtime on multiple CPU architectures

When to avoid

• you need maximum peak performance from aggressive optimizations
• you require guaranteed correctness beyond the tested platforms and test suites
• you need a mature, widely production-hardened JIT infrastructure
