Not sure what you need precisely, but in Polly (polly.llvm.org), we have
support for precise array data-flow analysis. Beyond this there are at
least two more data-analysis frameworks. One from the LLVM vectorizer
and one using more classical dependence analysis algorithms which was
written by Preston Briggs.

Can you given an example of what you would like to compute
