If you're just looking to be a client of alias analysis information, consider +using the Memory Dependence Analysis interface instead. MemDep is a lazy, +caching layer on top of alias analysis that is able to answer the question of +what preceding memory operations a given instruction depends on, either at an +intra- or inter-block level. Because of its laziness and caching +policy, using MemDep can be a significant performance win over accessing alias +analysis directly.
