As per wikipedia, elfutils is mentioned as, “Ulrich Drepper wrote elfutils, to replace GNU Binutils, purely for Linux and with support only for ELF and DWARF”
elfutils is a Red Hat project.
There is substantial overlap between elfutils (eu-addr2line, eu-elflint, eu-findtextrel, eu-nm, eu-readelf, eu-size, eu-strip, etc.) and binutils (addr2line, nm, readelf, size, strip, objdump, etc.)
Ulrich Drepper who authored elfutils has mentioned the differences as below,
– the tools in elfutils compared with binutils are a) smaller, b) faster (several times, usually), c) less buggy, d) more featureful
– there are several tools which are not available in binutils which are in (wide) use
– there are several more tools which use the elfutils libraries (systemtap, frysk, …)
