The Binary File Descriptor library, most commonly seen as just BFD, is the GNU Project's main mechanism for the portable manipulation of object files in a variety of formats. As of 2003, it supports approximately 50 file formats for some 25 processor architectures. Image File history File links Free_Software_Portal_Logo. ...

To a large extent, the design of a CPU, or central processing unit, is the design of its control unit. ...
BFD works by presenting a common abstract view of object files. An object file has a "header" with descriptive info; a variable number of "sections" that each have a name, some attributes, and a block of data; a symbol table; relocation entries; and so forth. In computer science, a symbol table is a data structure used by a language translator such as a compiler or interpreter, where each symbol in a programs source code is associated with information such as location, type and scope level. ...
Relocation is the process of replacing references to symbols with actual addresses during fragment preparation and it is typically done by the Linker. ...
Internally, BFD translates the data from the abstract view into the details of the bit/byte layout required by the target processor and file format. Its key services include handling byte order differences, such as between a little-endian host and big-endian target, correct conversion between 32-bit and 64-bit data, and details of address arithmetic specified by relocation entries. “CPU†redirects here. ...
When integers or any other data are represented with multiple bytes, there is no unique way of ordering of those bytes in memory or in a transmission over some medium, and so the order is subject to arbitrary convention. ...

Although BFD was originally designed to be a generic library usable by a wide variety of tools, its licensing under the GPL, and the frequent need to tinker with the API to accommodate new systems' capabilities has tended to limit its use; BFD's main clients are the GNU Assembler (GAS), GNU Linker (GLD), and other GNU Binary Utilities ("binutils") tools, and the GNU Debugger (GDB). As a result, BFD is not distributed separately, but is always included with releases of binutils and GDB.

Nevertheless, BFD is a critical component in the use of GNU tools for embedded systems development. When David Henkel-Wallace of Cygnus Support proposed developing the library, as a way to open up new business opportunities for the company, Richard Stallman said (correctly) that it would be hard; David's response was "BFD" (big fucking deal). This became the library name,[1] and "Binary File Descriptor" was invented later as the meaning of the letters. A router, an example of an embedded system. ...
