Definition: LLVM


A group of compiler tools that began as a research project at the University of Illinois. LLVM includes optimization, code generation, debugging and analysis tools that are used in several development environments. Written in C++, LLVM includes a native C/C++/Objective-C compiler, although many other languages, including Python, Ruby, C# and Swift, are front ends to LLVM. LLVM originally stood for "Low Level Virtual Machine," but the full name is no longer publicized.
