9 ; * -gmlt ('Emission Kind' of 'LineTablesOnly' in the CU debug info metadata)
10 ; doesn't produce ranges.
11 ; * if no ranges are produced, no debug_ranges list (not even an empty one) is
14 ; -gmlt means no DW_AT_ranges on the CU, even though there are parts of the CU
15 ; in different sections and this would normally necessitate a DW_AT_ranges
16 ; attribute on the CU.
