I am not sure what a data dependence graph is,
but Frama-C has a front-end that was forked from CIL
and it offers a plug-in architecture precisely intended to
reuse results of previous analyses (plug-ins).
There is a Program Dependency Graph plug-in that may
be somewhat like what you are looking for, that makes
its results available to a slicing plug-in, and that uses
results from a very precise value analysis to resolve
pointers, and a functional dependencies analysis to
handle function calls.
