Here is a slightly revised patch. I've added some missing comments for the new classes, and changed the fill method for .debug_line to set the header_length field to claim that the header spans the entire hole. Consumers that (correctly) use header_length to find the beginning of the line number program will see an empty line number program. Consumers that (incorrectly, like readelf/objdump) assume that the line number program begins immediately following the last filename entry of the header will have to parse all the "DW_LNS_set_basic_block" opcodes used as no-ops. -cary
