Clang does not accept Java or Fortran code. It links llvm, which has some language-specific support for calling conventions, but excising this support might not save you much in terms of binary size.

What are you measuring exactly? Is it the size of the build directory, the size of the clang binary itself, or something else?

How small does clang need to be for your purposes?
