You might have a look at our LANCE C compiler system. It comes with a
C frontend, a set of machine-independent optimizations, and an
interface to OLIVE/IBURG like backend generators. The backend
interface allows to develop working compiler prototypes relatively
quickly. LANCE is almost totally machine-independent. We have used it
to build compilers for a couple of DSPs, RISCs, and MCs.


As compared to GCC, LANCE is certainly easier to use, but it does not
support C++. As compared to LCC, there is more effort for writing the
backend, but LANCE includes more optimizations.
