The LLVM project will be releasing daily Debian/Ubuntu package snapshots of its compiler for those interested in testing out the very latest code.
To assist in those wanting to test out the very latest LLVM compiler, automated packages are now being produced routinely for Debian Wheezy/Unstable and Ubuntu 12.04/12.10/13.04 on i386 and AMD64 architectures. Packages are built twice daily for all architectures and operating systems in clean chroots.
This will make it much easier for conducting tests of the latest in-development LLVM/Clang and also for those like us interested in Phoromatic
-style nightly testing of the open-source compiler on the Phoronix Test Suite
For those wishing to learn more about the daily packages, see the LLVM.org blog post
