------------------------------------------------------------------------------ (gdb) help save gdb-index Save a gdb-index file. Usage: save gdb-index [-dwarf-5] DIRECTORY No options create one file with .gdb-index extension for pre-DWARF-5 compatible .gdb_index section. With -dwarf-5 creates two files with extension .debug_names and .debug_str for DWARF-5 .debug_names section. ------------------------------------------------------------------------------ But gdb-add-index command provided no way how to pass the -dwarf-5 option. gdb/ChangeLog 2018-07-07 Jan Kratochvil <jan.kratochvil@redhat.com> * contrib/gdb-add-index.sh ($dwarf5): New, use it.
