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

<!-- prevent bad page break with this line -->
<p>Here are macros for VMS debug format.

<div class="defun">
&mdash; Macro: <b>VMS_DEBUGGING_INFO</b><var><a name="index-VMS_005fDEBUGGING_005fINFO-4803"></a></var><br>
<blockquote><p>Define this macro if GCC should produce debugging output for VMS
in response to the <samp><span class="option">-g</span></samp> option.  The default behavior for VMS
is to generate minimal debug info for a traceback in the absence of
<samp><span class="option">-g</span></samp> unless explicitly overridden with <samp><span class="option">-g0</span></samp>.  This
behavior is controlled by <code>TARGET_OPTION_OPTIMIZATION</code> and
<code>TARGET_OPTION_OVERRIDE</code>.
