The name of the directive +describes which combination of four possible data fields follows. It is +either <code>.stabs</code> (string), <code>.stabn</code> (number), or <code>.stabd</code> +(dot). IBM’s XCOFF assembler uses <code>.stabx</code> (and some other +directives such as <code>.file</code> and <code>.bi</code>) instead of +<code>.stabs</code>, <code>.stabn</code> or <code>.stabd</code>. +</p> +<p>The overall format of each class of stab is: +</p> +<div class="example"> +<pre class="example">.stabs "<var>string</var>",<var>type</var>,<var>other</var>,<var>desc</var>,<var>value</var> +.stabn <var>type</var>,<var>other</var>,<var>desc</var>,<var>value</var> +.stabd <var>type</var>,<var>other</var>,<var>desc</var> +.stabx "<var>string</var>",<var>value</var>,<var>type</var>,<var>sdb-type</var> +</pre></div> + +<p>For <code>.stabn</code> and <code>.stabd</code>, there is no <var>string</var> (the +<code>n_strx</code> field is zero; see <a href="Symbol-Tables.html#Symbol-Tables">Symbol Tables</a>). For +<code>.stabd</code>, the <var>value</var> field is implicit and has the value of +the current file location. For <code>.stabx</code>, the <var>sdb-type</var> field +is unused for stabs and can always be set to zero. The <var>other</var> +field is almost always unused and can be set to zero. +</p> +<p>The number in the <var>type</var> field gives some basic information about +which type of stab this is (or whether it <em>is</em> a stab, as opposed +to an ordinary symbol). Each valid type number defines a different stab +type; further, the stab type defines the exact interpretation of, and +possible values for, any remaining <var>string</var>, <var>desc</var>, or +<var>value</var> fields present in the stab. See <a href="Stab-Types.html#Stab-Types">Stab Types</a>, for a list +in numeric order of the valid <var>type</var> field values for stab directives. +</p> + + + +</body> +</html> |
