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