Second, people who want to take off-the-shelf tools (like a C compiler) and use them. This talk describes some of the architectural features that enables the first class of people to be successful and talks about how LLVM is being used today. Then it talks about some of the really great end-user tools the LLVM provides, such as the Clang C/C++/Objective-C compiler (
