The LLVM compiler framework has gone from being a technological curiosity to a vital piece of the modern software landscape. It is the engine behind the Clang compiler, as well as the compilers for the Rust and Swift languages, and provides a powerful toolkit for creating new languages.
It is also a fairly fast-moving project, with major point revisions announced every six months or so. Version 6.0, released earlier this month, continues LLVM’s ongoing mission to deepen and broaden support for a variety of compilation targets. The update also adds many timely fixes to guard against recently discovered processor-level system attacks.
