Mark Wielaard edc7a80a9c gas: Don't error when .debug_line already exists, unless .loc was used ... When -g was used to generate DWARF gas would error out when a .debug_line already exists. But when a .debug_info section already exists it would simply skip generating one without warning or error. Do the same for .debug_line. It is only an error when the user explicitly uses .loc directives and also generates the .debug_line table itself. The tests are unfortunately arch specific because the line table is only generated when actual instructions have been emitted. Use i386 because that is probably the most used architecture. Before this patch the new dwarf-line-2 testcase would fail, with this patch it succeeds (and doesn't try to add its own line table). gas/ChangeLog: * as.texi (-g): Explicitly mention when .debug_info and .debug_line are generated for the DWARF format. (Loc): Add that it is an error to both use a .loc directive and generate a .debug_line yourself. * dwarf2dbg.c (dwarf2_any_loc_directive_seen): New static variable. (dwarf2_directive_loc): Set dwarf2_any_loc_directive_seen to TRUE. (dwarf2_finish): Check dwarf2_any_loc_directive_seen before emitting an error. Only create .debug_line if it is empty (or doesn't exist). * testsuite/gas/i386/i386.exp: Add dwarf2-line-{1,2,3,4} when testing an elf target. * testsuite/gas/i386/dwarf2-line-{1,2,3,4}.{s,d,l}: New test files.		2020-09-11 19:18:44 +02:00
