Hi Pascal,

I think what your mentioned as "data dependencies" is data-flow analysis, 

and I guess "data dependencies" you want is "def-use chain".

I searched and think this simple implementation may work for you:

If you want a more complete and strong analysis, you could check SVF:

(sorry, I forgot to cc mailing-list in the last email)

Subject:  [llvm-dev] LLVM Use Def Analysis

Dear LLVM Developers,

I am a student at TU Darmstadt and I am currently working with LLVM in  
a project to extract data dependencies from a program.

Since I want to use a use-def chain but didn't find a corresponding  
Pass in LLVM, I would like to ask you, if there is an existing  
LLVM-Pass for use-def analysis.

I am looking forward to hearing from you.

Best regards,
Pascal Hefter
