2013 EuroLLVM Developers’ Meeting: C. Carruth “Optimization in LLVM - Numbers, A Case Study, ...”

http://llvm.org/devmtg/2013-04/ — Optimization in LLVM - Numbers, A Case Study, and Looking Forward - Chandler Carruth - Google — With all of the excitement surrounding Clang, LLD, LLDB, Sanitizers, and other projects in LLVM, it is easy to let its origins slip your mind. However, LLVM was and remains a platform for optimizing compilers and related parts of the toolchain. Today, the LLVM + Clang optimizing C++ compiler is very powerful and can handle a wide range of code, but how well does it compete with modern versions of GCC? What are the root causes of some of the more striking differences? What is coming next in LLVM that will significantly impact the optimizing power of the toolchain? — Note: Video uploaded for historically reasons.
