No, I don't think that LLVM would be useful for making a
source-to-source compiler. LLVM itself is mostly concerned with
optimizations and code generation. It doesn't have any code for
representing any high-level ASTs or doing type checking on them. You
could look at clang, though, if for some reason you need an AST for C.
