I do not believe that this would be the case nor that it should be a 
goal. Source-to-source transformation requires a lot of accurate 
information about the AST, and conversion to LLVM IR is way too lossy. 
Signedness, for example, is lost at IR generation, as is any pretense of 
machine independence.
