|
|
|
|
<p>The COFF format supports a multitude of auxiliary symbol attributes;
|
|
like the primary symbol attributes, they are set between <code>.def</code> and
|
|
<code>.endef</code> directives.

|
|
<h4 class="subsubsection">5.5.4.1 Primary Attributes</h4>
|
|
|
|
<a name="index-primary-attributes_002c-COFF-symbols"></a>
|
|
<p>The symbol name is set with <code>.def</code>; the value and type,
|
|
respectively, with <code>.val</code> and <code>.type</code>.
|
|
</p>
|
|
<a name="Auxiliary-Attributes"></a>
|
|
<h4 class="subsubsection">5.5.4.2 Auxiliary Attributes</h4>
|
|
|
|
<a name="index-auxiliary-attributes_002c-COFF-symbols"></a>
|
|
<p>The <code>as</code> directives <code>.dim</code>, <code>.line</code>, <code>.scl</code>,
|
|
<code>.size</code>, <code>.tag</code>, and <code>.weak</code> can generate auxiliary symbol
|
|
table information for COFF.
