<h4 class="subsection">9.3.4 ARC Assembler Modifiers</h4>

<p>The following additional assembler modifiers have been added for
position-independent code.  These modifiers are available only with
the ARC 700 and above processors and generate relocation entries,
which are interpreted by the linker as follows:
</p>
<dl compact="compact">
<dt><code>@pcl(<var>symbol</var>)</code></dt>
<dd><a name="index-_0040pcl_0028symbol_0029_002c-ARC-modifier"></a>
<p>Relative distance of <var>symbol</var>&rsquo;s from the current program counter
location.
</p>
</dd>
<dt><code>@gotpc(<var>symbol</var>)</code></dt>
<dd><a name="index-_0040gotpc_0028symbol_0029_002c-ARC-modifier"></a>
<p>Relative distance of <var>symbol</var>&rsquo;s Global Offset Table entry from the
current program counter location.
</p>
</dd>
<dt><code>@gotoff(<var>symbol</var>)</code></dt>
<dd><a name="index-_0040gotoff_0028symbol_0029_002c-ARC-modifier"></a>
<p>Distance of <var>symbol</var> from the base of the Global Offset Table.
</p>
</dd>
<dt><code>@plt(<var>symbol</var>)</code></dt>
<dd><a name="index-_0040plt_0028symbol_0029_002c-ARC-modifier"></a>
<p>Distance of <var>symbol</var>&rsquo;s Procedure Linkage Table entry from the
current program counter.  This is valid only with branch and link
instructions and PC-relative calls.
</p>
</dd>
<dt><code>@sda(<var>symbol</var>)</code></dt>
<dd><a name="index-_0040sda_0028symbol_0029_002c-ARC-modifier"></a>
<p>Relative distance of <var>symbol</var> from the base of the Small Data
Pointer.
