| <p><a name="index-g_t_0040code_007bloc_005fmark_005flabels_007d-directive-387"></a>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. |
