| <h4 class="subsection">3.5.2 HIDDEN</h4> |
| |
| <p><a name="index-HIDDEN-447"></a>For ELF targeted ports, define a symbol that will be hidden and won't be |
| exported. The syntax is <code>HIDDEN(</code><var>symbol</var><code> = </code><var>expression</var><code>)</code>. |
| |
| <p>Here is the example from <a href="Simple-Assignments.html#Simple-Assignments">Simple Assignments</a>, rewritten to use |
| <code>HIDDEN</code>: |
| |
| <pre class="smallexample"> HIDDEN(floating_point = 0); |
| SECTIONS |
| { |
| .text : |
| { |
| *(.text) |
| HIDDEN(_etext = .); |
| } |
| HIDDEN(_bdata = (. + 3) & ~ 3); |
| .data : { *(.data) } |
| } |
| </pre> |
| <p class="noindent">In this case none of the three symbols will be visible outside this module. |
