A C language family frontend for LLVM. The goal of the Clang project is to create a new C, C++, Objective C and Objective C++ front-end for the LLVM compiler.
Clang is considered to be a production quality C, Objective-C, C++ and Objective-C++ compiler when targeting X86-32, X86-64, and ARM (other targets may have caveats, but are usually easy to fix). If you are looking for source analysis or source-to-source transformation tools, clang is probably a great solution for you.
