This fourth "EuroLLVM" conference attracted more than 200 LLVM stakeholders and was held at the University of Edinburgh on the 7th and 8th of April.
Videos are still forthcoming, but slides from nearly all of the presentations over the two days have been posted. For compiler enthusiasts and C/C++ programmers in particular the slides are worth checking out. The slides cover new features of C++14, Link-Time Optimizations in LLVM, how to build LLVM very quickly, Clang-Tidy, an LLVM JIT compiler for Erlang, targeting HHVM's JIT compiler into LLVM, LLVM data structures, and Intel's Clang-based C++ compiler.
