The <var>fullname</var> field can be elided if the absolute +name of the source file can’t be computed. The field +<var>debug-fully-read</var> will be a string, either <code>true</code> or +<code>false</code>.

If <code>--basename</code> +is provided, then <var>regexp</var> is matched against the basename of each +source file. Only one of <code>--dirname</code> or <code>--basename</code> may be +given, and if either is given then <var>regexp</var> is required. +</p> +<p>If <code>--group-by-objfile</code> is used then the format of the results is +changed. The results will now be a list of tuples, with each tuple +representing an object file (executable or shared library) loaded into +<small>GDB</small>. The fields of these tuples are; <var>filename</var>, +<var>debug-info</var>, and <var>sources</var>. The <var>filename</var> is the +absolute name of the object file, <var>debug-info</var> is a string with +one of the following values: +</p> +<dl compact="compact"> +<dt><code>none</code></dt> +<dd><p>This object file has no debug information. +</p></dd> +<dt><code>partially-read</code></dt> +<dd><p>This object file has debug information, but it is not fully read in +yet.
