-<p>Occasionally, the front-end needs to transmit data to the linker which
- affects its behavior. The LLVM IR isn't sufficient to transmit this
- information, so one should use the <tt>llvm.module.flags</tt> named
- metadata.</p>
-
-<p>The <tt>llvm.module.flags</tt> metadata is a named metadata, whose elements
- consist of metadata triplets. For example:</p>
-
-<pre class="doc_code">
-!0 = metadata !{ i32 0, metadata !"foo", i32 1 }
-!1 = metadata !{ i32 1, metadata !"bar", i32 37 }
-
-!llvm.module.flags = !{ !0, !1 }
-</pre>
-
-<p>The first field specifies the behavior of the linker upon encountering two of
- the same values. Behavior could range from: emitting an error if some of the
- modules' flags disagree, emitting a warning, etc. The second field is the
- name of the metadata. The third field is the value of the metadata.</p>
-
-<p>When two modules are linked together, the <tt>llvm.module.flags</tt> metadata
- are unioned together.</p>
