+<p>Any memory access must be done though a pointer value associated
+with with address range of the memory access, otherwise the behavior
+is undefined. Pointer values are associated with address ranges
+according to the following rules:</p>
+
+<ul>
+  <li>A pointer value formed from a <tt>getelementptr</tt> instruction is
+      associated with the addresses associated with the first operand of
+      the <tt>getelementptr</tt>.</li>
+  <li>An addresses of a global variable is associated with the address
+      range of the variable's storage.</li>
+  <li>The result value of an allocation instruction is associated with
+      the address range of the allocated storage.</li>
+  <li>A null pointer in the default address-space is associated with
+      no addresses.</li>
+  <li>A pointer value formed by an <tt>inttoptr</tt> is associated with
+      all address ranges of all pointer values that contribute (directly
+      or indirectly) to the computation of the pointer's value.</li>
+  <li>The result value of a <tt>bitcast</tt> is associated with all
+      addresses associated with the operand of the <tt>bitcast</tt>.</li>
+  <li>An integer constant other than zero or a pointer value returned
+      from a function not defined within LLVM may be associated with address
+      ranges allocated through mechanisms other than those provided by
+      LLVM. Such ranges shall not overlap with any ranges of address
+      allocated by mechanisms provided by LLVM.</li>
+  </ul>
+
+<p>LLVM IR does not associate types with memory. The result type of a
+<tt>load</tt> merely indicates the size and alignment of the memory from
+which to load, as well as the interpretation of the value. The first
+operand of a <tt>store</tt> similarly only indicates the size and
+alignment of the store.</p>
+
+<p>Consequently, type-based alias analysis, aka TBAA, aka
+<tt>-fstrict-aliasing</tt>, is not applicable to general unadorned
+LLVM IR. <a href="#metadata">Metadata</a> may be used to encode
+additional information which specialized optimization passes may use
+to implement type-based alias analysis.</p>
