He's probably referring to so-called 'llvm-gcc':

<https://developer.apple.com/library/mac/documentation/Darwin/Reference/ManPages/man1/llvm-gcc.1.html>

which is a compiler consisting of the gcc front end and llvm back end.  It was the default Xcode compiler at one point (forget exactly which versions) but is no longer being worked on.  For Apple, it served the purpose of being a transition between gcc and clang.
