72<a name="index-HIDDEN"></a>
73<p>For ELF targeted ports, define a symbol that will be hidden and won&rsquo;t be
74exported.  The syntax is <code>HIDDEN(<var>symbol</var> = <var>expression</var>)</code>.
75</p>
76<p>Here is the example from <a href="Simple-Assignments.html#Simple-Assignments">Simple Assignments</a>, rewritten to use
77<code>HIDDEN</code>:
78</p>
79<div class="smallexample">
80<pre class="smallexample">HIDDEN(floating_point = 0);
81SECTIONS
82{
83  .text :
84    {
85      *(.text)
86      HIDDEN(_etext = .);
87    }
88  HIDDEN(_bdata = (. + 3) &amp; ~ 3);
89  .data : { *(.data) }
90}
91</pre></div>
92<p>In this case none of the three symbols will be visible outside this module.
