2.11. binutils, the GNU Binary Utilities

binutils, the GNU binary utilities, include ar, nm, objcopy, objdump, ranlib, size, strings, and strip. For targets that use the ELF file format, there is also a tool called readelf.

There are three binary utilities, addr2line, windres, and dlltool, that are for use with Cygwin, the porting layer application for Win32 development. The most important of the binary utilities are objcopy and objdump.
