 <h5>Syntax:</h5>
-<pre>  declare void %llvm.va_end(<va_list*> <arglist>)<br></pre>
+<pre>  declare void %llvm.va_end(i8* <arglist>)<br></pre>
 <h5>Overview:</h5>
+
 <p>The '<tt>llvm.va_end</tt>' intrinsic destroys <tt><arglist></tt>
 which has been initialized previously with <tt><a href="#i_va_start">llvm.va_start</a></tt>
 or <tt><a href="#i_va_copy">llvm.va_copy</a></tt>.</p>
+
 <h5>Arguments:</h5>
+
 <p>The argument is a <tt>va_list</tt> to destroy.</p>
+
 <h5>Semantics:</h5>
+
 <p>The '<tt>llvm.va_end</tt>' intrinsic works just like the <tt>va_end</tt>
 macro available in C.  In a target-dependent way, it destroys the <tt>va_list</tt>.
 Calls to <a href="#i_va_start"><tt>llvm.va_start</tt></a> and <a
  href="#i_va_copy"><tt>llvm.va_copy</tt></a> must be matched exactly
 with calls to <tt>llvm.va_end</tt>.</p>
