Rafael Avila de Espindola is the fifth most active contributor to LLVM with more than 4,300 commits since 2006, but now he has decided to part ways with the project . From a report:"I am definitely sad to lose Rafael from the LLVM project, but it is critical to the long term health of the project that we preserve an inclusive community. I applaud Rafael for standing by his personal principles, this must have been a hard decision," Chris Lattner tweeted Thursday.
