GNU lightning is an open source library that generates assembly language code at run-time. It is extremely fast and is usable in complex code generation tasks, making it useful for just-in-time compiler applications. Unlike for example LLVM or libJIT, it only provides a low-level interface that assembles a standardized RISC architecture loosely based on the SPARC and MIPS[2] into the target architecture's machine language. It does not provide register allocation, data-flow, and control-flow analysis, or optimization. Supported backends are SPARC (32-bit), x86 (32- and 64-bit) and PowerPC (32-bit). MzScheme, GNU Smalltalk, and CLISP[3] make use of GNU lightning for just-in-time compilation.
