- <p>For ELF targeted ports, define a symbol that will be hidden and won’t be
- exported. The syntax is <code>HIDDEN(<var>symbol</var> = <var>expression</var>)</code>.
- </p>
- <p>Here is the example from <a href="Simple-Assignments.html#Simple-Assignments">Simple Assignments</a>, rewritten to use
- <code>HIDDEN</code>:
- </p>
- <div class="smallexample">
- <pre class="smallexample">HIDDEN(floating_point = 0);
- SECTIONS
- {
- .text :
- {
- *(.text)
- HIDDEN(_etext = .);
- }
- HIDDEN(_bdata = (. + 3) & ~ 3);
- .data : { *(.data) }
- }
- </pre></div>
- <p>In this case none of the three symbols will be visible outside this module.
