-<p>The <tt>-anders-aa</tt> pass implements the well-known "Andersen's algorithm"
-for interprocedural alias analysis. This algorithm is a subset-based,
-flow-insensitive, context-insensitive, and field-insensitive alias analysis that
-is widely believed to be fairly precise. Unfortunately, this algorithm is also
-O(N<sup>3</sup>). The LLVM implementation currently does not implement any of
-the refinements (such as "online cycle elimination" or "offline variable
-substitution") to improve its efficiency, so it can be quite slow in common
-cases.
