FreeBSD 10 now uses the clang front end for the LLVM compiler by default, and no longer ships with GCC in the base image. The clang project has grown quickly in the past few years, thanks in large part to Apple including it as the default compiler in Xcode, the development environment used to build iOS and OS X applications. The FreeBSD “what’s new” page simply states that “GCC is no longer a part of the default base system on architectures where CLANG is used instead. CLANG is used on i386 and AMD64.” The clang project claims that clang has “fast compiles and low memory use”, and sports GCC compatibility.
