Installed programs: addr2line, ar, as, c++filt, dwp, elfedit, gprof, ld, ld.bfd, ld.gold, nm, objcopy, objdump, ranlib, readelf, size, strings, and strip
Installed libraries: libbfd.{a,so} and libopcodes.{a,so}
Installed directory: /usr/lib/ldscripts
Short Descriptions
addr2line Translates program addresses to file names and line numbers; given an address and the name of an executable, it uses the debugging information in the executable to determine which source file and line number are associated with the address
ar Creates, modifies, and extracts from archives
as An assembler that assembles the output of gcc into object files
c++filt Used by the linker to de-mangle C++ and Java symbols and to keep overloaded functions from clashing
dwp The DWARF packaging utility
elfedit Updates the ELF header of ELF files
gprof Displays call graph profile data
ld A linker that combines a number of object and archive files into a single file, relocating their data and tying up symbol references
ld.gold A cut down version of ld that only supports the elf object file format
ld.bfd Hard link to ld
nm Lists the symbols occurring in a given object file
objcopy Translates one type of object file into another
objdump Displays information about the given object file, with options controlling the particular information to display; the information shown is useful to programmers who are working on the compilation tools
ranlib Generates an index of the contents of an archive and stores it in the archive; the index lists all of the symbols defined by archive members that are relocatable object files
readelf Displays information about ELF type binaries
size Lists the section sizes and the total size for the given object files
strings Outputs, for each given file, the sequences of printable characters that are of at least the specified length (defaulting to four); for object files, it prints, by default, only the strings from the initializing and loading sections while for other types of files, it scans the entire file
strip Discards symbols from object files
libbfd The Binary File Descriptor library
libopcodes A library for dealing with opcodes—the “readable text” versions of instructions for the processor; it is used for building utilities like objdump
