The name "LLVM" itself is not an acronym; it + is the full name of the project. + LLVM began as a research project at the University of Illinois, with the + goal of providing a modern, SSA-based compilation strategy capable of + supporting both static and dynamic compilation of arbitrary programming + languages. Since then, LLVM has grown to be an umbrella project consisting + of a number of subprojects, many of which are being used in production by + a wide variety of commercial and open source projects as well as being + widely used in academic research.
