<h4 class="subsection">17.21.6 Macros for VMS Debug Format</h4>

<p>Here are macros for VMS debug format.
</p>
<dl>
<dt><a name="index-VMS_005fDEBUGGING_005fINFO"></a>Macro: <strong>VMS_DEBUGGING_INFO</strong></dt>
<dd><p>Define this macro if GCC should produce debugging output for VMS
in response to the <samp>-g</samp> option.  The default behavior for VMS
is to generate minimal debug info for a traceback in the absence of
<samp>-g</samp> unless explicitly overridden with <samp>-g0</samp>.  This
behavior is controlled by <code>TARGET_OPTION_OPTIMIZATION</code> and
<code>TARGET_OPTION_OVERRIDE</code>.
