For the last 3 years, I've been building a complete Linux distribution, Chimera Linux (https://chimera-linux.org) using solely LLVM as its system toolchain - that means Clang, compiler-rt, and libc++, alongside its other tooling. Right now, it is a complete desktop system that is already used by many, with a familiar GNOME interface and thousands of packages, targeting 5 CPU architectures. In this talk I would like to focus on my experiences using the toolchain, what obstacles got in the way, how I dealt with them, the issues that are still left and I would like to see addressed, the many benefits using LLVM gave the project, and overall give the audience an insight into practical deployment of LLVM in a project where it isn't simply a drop-in alternative to GCC.
