Many language designers/implementors have turned to using C as an intermediate
representation language, for example in the following research projects and/or
products:


- C++ translator from AT&T (cfront)
- portable Cedar compiler developed at Xerox PARC
- Eiffel compiler from ISE
- Modula-3 compilers developed at DEC SRC and the (now defunct?) Olivetti
    Research Center


Compilation speed using C as an IRL may not be overwhelming, but this solution
is certainly portable. Of course, the quality of the generated machine code
depends substantially on on the C compiler used as a backend.
