### 7.74 `.loc_mark_labels` enable

When emitting DWARF2 line number information, the `.loc_mark_labels` directive makes the assembler emit an entry to the `.debug_line` line number matrix with the `basic_block` register in the state machine set whenever a code label is seen. The enable argument should be either 1 or 0, to enable or disable this function respectively.
