<h4 class="subsection">3.6.1 Output Section Description</h4>
|
||
|
|
|
||
|
|
<p>The full description of an output section looks like this:
|
||
|
|
<pre class="smallexample"> <var>section</var> [<var>address</var>] [(<var>type</var>)] :
|
||
|
|
[AT(<var>lma</var>)] [ALIGN(<var>section_align</var>)] [SUBALIGN(<var>subsection_align</var>)]
|
||
|
|
{
|
||
|
|
<var>output-section-command</var>
|
||
|
|
<var>output-section-command</var>
|
||
|
|
...
|
||
|
|
} [><var>region</var>] [AT><var>lma_region</var>] [:<var>phdr</var> :<var>phdr</var> ...] [=<var>fillexp</var>]
|
||
|
|
</pre>
|
||
|
|
<p>Most output sections do not use most of the optional section attributes.
|
||
|
|
|
||
|
|
<p>The whitespace around <var>section</var> is required, so that the section
|
||
|
|
name is unambiguous. The colon and the curly braces are also required.
|
||
|
|
The line breaks and other white space are optional.
|
||
|
|
|
||
|
|
<p>Each <var>output-section-command</var> may be one of the following:
|
||
|
|
|
||
|
|
<ul>
|
||
|
|
<li>a symbol assignment (see <a href="Assignments.html#Assignments">Assignments</a>)
|
||
|
|
<li>an input section description (see <a href="Input-Section.html#Input-Section">Input Section</a>)
|
||
|
|
<li>data values to include directly (see <a href="Output-Section-Data.html#Output-Section-Data">Output Section Data</a>)
|
||
|
|
<li>a special output section keyword (see <a href="Output-Section-Keywords.html#Output-Section-Keywords">Output Section Keywords</a>)
|
||
|
|
</ul>
|
||
|
|
|
||
