| <p>The full description of an output section looks like this: |
| </p><div class="smallexample"> |
| <pre class="smallexample"><var>section</var> [<var>address</var>] [(<var>type</var>)] : |
| [AT(<var>lma</var>)] |
| [ALIGN(<var>section_align</var>) | ALIGN_WITH_INPUT] |
| [SUBALIGN(<var>subsection_align</var>)] |
| [<var>constraint</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></div> |
| |
| <p>Most output sections do not use most of the optional section attributes. |
| </p> |
| <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> |
| <p>Each <var>output-section-command</var> may be one of the following: |
| </p> |
| <ul> |
| <li> a symbol assignment (see <a href="Assignments.html#Assignments">Assignments</a>) |
| </li><li> an input section description (see <a href="Input-Section.html#Input-Section">Input Section</a>) |
| </li><li> data values to include directly (see <a href="Output-Section-Data.html#Output-Section-Data">Output Section Data</a>) |
| </li><li> a special output section keyword (see <a href="Output-Section-Keywords.html#Output-Section-Keywords">Output Section Keywords</a>) |
| </li></ul> |
