Correct. Clang is the LLVM front-end for that family of languages.

There are other LLVM front-ends for different languages. Plus you can
use GCC to compile to an intermediate representation and then let LLVM
do the rest.

Clang aims to be completely gcc compatible. It isn't quite there yet.
Most of the ports that don't compile with clang are actually doing
questionable things with their code that gcc should probably reject too.
