SLJIT is a platform-independent, low-level JIT compiler library written in C, designed for translating bytecode into machine code. It supports many CPU architectures and offers features like register access, SIMD, atomic operations, and serializable compilation for AOT workflows.

Use cases

• generate machine code from bytecode at runtime
• build a JIT compiler for a scripting language
• compile regex patterns to native code
• do ahead-of-time compilation via serialized compiler state
• target multiple CPU architectures from one codegen API

When to choose

• you need a lightweight, embeddable JIT backend in C
• you must support many architectures (x86, ARM, RISC-V, MIPS, PowerPC, s390x, LoongArch)
• you want fine-grained control over registers and code generation

When to avoid

• you want a high-level IR with optimizations like LLVM provides
• your project is not in C/C++ or lacks a C FFI
• you only need an interpreter without native code generation
