<p>The <tt>AliasAnalysis</tt> class also provides a <tt>getModRefInfo</tt>

call sites (CS1 &amp; CS2), returns NoModRef if the two calls refer to disjoint
memory locations, Ref if CS1 reads memory written by CS2, Mod if CS1 writes to
memory read or written by CS2, or ModRef if CS1 might read or write memory
accessed by CS2. Note that this relation is not commutative.</p>
