+    Globals with "``available_externally``" linkage are never emitted into

+    perspective, an ``available_externally`` global is equivalent to
+    an external declaration. They exist to allow inlining and other
+    optimizations to take place given knowledge of the definition of the
+    global, which is known to be somewhere outside the module. Globals

 ``linkonce``
     Globals with "``linkonce``" linkage are merged with other globals of
     the same name when linkage occurs. This can be used to implement
