In October last year, it was reported that LLVM (Low-Level Virtual Machine) is moving from Apache Subversion (SVN) to GitHub. Now the migration is complete and LLVM is available on GitHub. This transition was long under discussion and is now officially complete. LLVM is a toolkit for creating compilers, optimizers, and runtime environments.
This migration comes in place as continuous integration is sometimes broken in LLVM because the SVN server was down. They migrated to GitHub for services lacking in SVN such as better 24/7 stability, disk space, code browsing, forking etc. GitHub is also used by most of the LLVM community. There already were unofficial mirrors on GitHub before this official migration.
Last week, James Y Knight from the LLVM team wrote to a mailing list: “The new official monorepo is published to LLVM’s GitHub organization, at: https://github.com/llvm/llvm-project. At this point, the repository should be considered stable — there won’t be any more rewrites which invalidate commit hashes (barring some _REALLY_ good reason…)”
Along with LLVM, this monorepo also hosts Clang, LLD, Compiler-RT, and other LLVM sub-projects. Commits are being made to the LLVM GitHub repository even at the time of writing and the repo currently has about 200 stars.
Updated workflow documents and instructions on migrating user work that is in-progress are being drafted and will be available soon. This move was initiated after positive responses from LLVM community members to migrate to GitHub.
