(for listing the section sizes of an object or archive file),
strip (for discarding symbols), readelf (to see the raw ELF file
structures), elflint (to check for well-formed ELF files) and

ChangeLog:

* Fri Jun 1 2018 Mark Wielaard <mjw@fedoraproject.org> - 0.171-1
- New upstream release.
- DWARF5 and split dwarf, including GNU DebugFission, support.
- readelf: Handle all new DWARF5 sections.
--debug-dump=info+ will show split unit DIEs when found.
--dwarf-skeleton can be used when inspecting a .dwo file.
Recognizes GNU locviews with --debug-dump=loc.
- libdw: New functions dwarf_die_addr_die, dwarf_get_units,
dwarf_getabbrevattr_data and dwarf_cu_info.
libdw will now try to resolve the alt file on first use
when not set yet with dwarf_set_alt.
dwarf_aggregate_size() now works with multi-dimensional arrays.
- libdwfl: Use process_vm_readv when available instead of ptrace.
- backends: Add a RISC-V backend.
