Re-generating source code from LLVM parsing tree?

Question

I am curious if there are any projects out there that can take the LLVM parsing tree and regenerate the source code. I especially think about C / C ++.

Answer 1

If "LLVM Parse Tree" is an AST from clang

Yes, you can restore the source from clang AST. Some links:

• Basic source-to-source conversion with Clang from Eli, 2012
• Modern source-to-source conversion with Clang and libTooling by Eli, 2014
• Performing Source-to-Source Transforms with Clang (slides)
• SoSlang: SOurce-to-Source Clang ()
