Widespread interest in LLVM has led to several efforts to develop new front ends for a variety of languages. The one that has received the most attention is Clang, a new compiler supporting C, C++, and Objective-C. Primarily supported by Apple, Clang is aimed at replacing the C/Objective-C compiler in the GCC system with a system that is more easily integrated with integrated development environments (IDEs) and has wider support for multithreading. Support for OpenMP directives has been included in Clang since release 3.8.
