To back this up: GCC ships with frontends for C/C++/ObjC, Fortran, Java,
Go, and Ada. AFAIK, the Java frontend is in maintenance mode and not
actively developed anymore, and I'm not sure about Go's status, since
the Go people have their own compiler nowadays.

LLVM already has native frontends for C/C++/ObjC (clang), Java, and Go,
and a maybe halfway finished one for Fortran. So it seems the only GCC
frontend that LLVM is actually missing is Ada.
