Not really, the frontend compiles everything to an intermediate form,
and then the backend converts the intermediate form into native code.
There's not much interaction between them. In particular, the backend is
the same backend used for C++. It doesn't have anything which is D-specific.

That behaviour is fairly common in C++ compilers.
