"LLVM-GCC is a C front-end for the Low-Level Virtual Machine but its back-end is a modified version of GCC (4.2). LLVM has its own compiler front-end, clang, for C and C++, but it is not nearly as complete or mature as the GNU Compiler Collection. Clang has been improving in recent times, but some portions are still incomplete (largely with C++). LLVM-GCC is provided with Xcode 3.2 found in Mac OS X 10.6, but it can also be found in several distribution package repositories, including Ubuntu. Apple though is the primary sponsor of the Low-Level Virtual Machine. LLVM/Clang is actually replacing GCC in FreeBSD Base. While we are not testing Clang in this article, for a comparison of Clang against GCC, read LLVM's comparison. Additional information on this open-source compiler infrastructure is available from the project's web-site. LLVM is also used by Apple in their OpenCL implementation and is finding uses on Linux within Gallium3D.
