71
72<p>The following additional assembler modifiers have been added for
73position-independent code.  These modifiers are available only with
74the ARC 700 and above processors and generate relocation entries,
75which are interpreted by the linker as follows:
76</p>
77<dl compact="compact">
78<dt><code>@pcl(<var>symbol</var>)</code></dt>
79<dd><a name="index-_0040pcl_0028symbol_0029_002c-ARC-modifier"></a>
80<p>Relative distance of <var>symbol</var>&rsquo;s from the current program counter
81location.
82</p>
83</dd>
84<dt><code>@gotpc(<var>symbol</var>)</code></dt>
85<dd><a name="index-_0040gotpc_0028symbol_0029_002c-ARC-modifier"></a>
86<p>Relative distance of <var>symbol</var>&rsquo;s Global Offset Table entry from the
87current program counter location.
88</p>
89</dd>
90<dt><code>@gotoff(<var>symbol</var>)</code></dt>
91<dd><a name="index-_0040gotoff_0028symbol_0029_002c-ARC-modifier"></a>
92<p>Distance of <var>symbol</var> from the base of the Global Offset Table.
93</p>
94</dd>
95<dt><code>@plt(<var>symbol</var>)</code></dt>
96<dd><a name="index-_0040plt_0028symbol_0029_002c-ARC-modifier"></a>
97<p>Distance of <var>symbol</var>&rsquo;s Procedure Linkage Table entry from the
98current program counter.  This is valid only with branch and link
99instructions and PC-relative calls.
100</p>
101</dd>
102<dt><code>@sda(<var>symbol</var>)</code></dt>
103<dd><a name="index-_0040sda_0028symbol_0029_002c-ARC-modifier"></a>
104<p>Relative distance of <var>symbol</var> from the base of the Small Data
105Pointer.
