<a name="index-loc_005fmark_005flabels-directive"></a>
<p>When emitting DWARF2 line number information,
the <code>.loc_mark_labels</code> directive makes the assembler emit an entry
to the <code>.debug_line</code> line number matrix with the <code>basic_block</code>
register in the state machine set whenever a code label is seen.
The <var>enable</var> argument should be either 1 or 0, to enable or disable
this function respectively.
