GNU lightning is a free software library for generating assembly language code at run-time. Newly released version 2.0[3] supports backends for SPARC (32-bit), x86 (32- and 64-bit), MIPS, ARM, ia64, HPPA and PowerPC (32-bit).
Advantages Over Other Libraries
The features GNU lightning provides make it useful for just-in-time compiler applications. In comparison to libraries such as LLVM or libJIT, GNU lightning provides only a low-level interface for assembling from a standardized RISC assembly language—loosely based on the SPARC and MIPS architectures[4]—into the target architecture's machine language.
Disadvantages
It does not provide register allocation, data-flow or control-flow analysis, or optimization.
Projects that use GNU Lightning
Racket, GNU Smalltalk, and CLISP[5] make use of GNU lightning for just-in-time compilation.
