Johannes Doerfert 22e6e108e1 [BasicAA] Use dereferenceability to reason about aliasing ... Summary: We already use the fact that an object with known size X does not alias another objection of size Y > X before. With this commit, we use dereferenceability information to determine a lower bound for Y and not only rely on the user provided query size. The result for @global_and_deref_arg_2() and @local_and_deref_ret_2() in test/Analysis/BasicAA/dereferenceable.ll improved with this patch.
