  66. <a name="index-symbolic-constants"></a>
  67. <a name="index-CONSTANT"></a>
  68. <p>It is possible to refer to target specific constants via the use of
  69. the <code>CONSTANT(<var>name</var>)</code> operator, where <var>name</var> is one of:
  70. </p>
  71. <dl compact="compact">
  72. <dt><code>MAXPAGESIZE</code></dt>
  73. <dd><a name="index-MAXPAGESIZE"></a>
  74. <p>The target&rsquo;s maximum page size.
  75. </p>
  76. </dd>
  77. <dt><code>COMMONPAGESIZE</code></dt>
  78. <dd><a name="index-COMMONPAGESIZE"></a>
  79. <p>The target&rsquo;s default page size.
  80. </p></dd>
  81. </dl>
  82. <p>So for example:
  83. </p>
  84. <div class="smallexample">
  85. <pre class="smallexample"> .text ALIGN (CONSTANT (MAXPAGESIZE)) : { *(.text) }
  86. </pre></div>
  87. <p>will create a text section aligned to the largest page boundary
  88. supported by the target.
