The LLVM Compiler Infrastructure Project

This page lists the people and organizations that have used or are currently using LLVM in research, education, industry, or open source development. It only includes users who have publicly discussed their use of LLVM in one form or another (mentioned it on llvmdev, published work on it, etc.). We believe there are many other users not listed here and would welcome a brief note telling us about your use so that we can add you to the list.
