The Low-Level Virtual Machine (LLVM) is a collection of libraries and tools that make it easy to build compilers, optimizers, Just-In-Time code generators, and many other compiler-related programs. LLVM uses a single, language-independent virtual instruction set both as an offline code representation (to communicate code between compiler phases and to run-time systems) and as the compiler internal representation (to analyze and transform programs). This persistent code representation allows a common set of sophisticated compiler techniques to be applied at compile-time, link-time, install-time, run-time, or "idle-time" (between program runs).
The strengths of the LLVM infrastructure are its extremely simple design (which makes it easy to understand and use), source-language independence, powerful mid-level optimizer, automated compiler debugging support, extensibility, and its stability and reliability. LLVM is currently being used to host a wide variety of academic research projects and commercial projects. LLVM includes C and C++ front-ends (based on GCC 4.0.1), a front-end for a Forth-like language (Stacker), a young scheme front-end, and Java support is in development. LLVM can generate code for X86, SparcV9, PowerPC, or it can emit C code.
