Clang project is a C, C++, Objective C and Objective C++ front-end for the LLVM compiler. Its goal is to offer a replacement to the GNU Compiler Collection (GCC).

Clang fully implements all published ISO C++ standards including C++11, as well as the upcoming C++14 standard, and some parts of the fledgling C++1z standard, and is considered a production-quality C++ compiler.
