<p><a name="index-BFD-1"></a><a name="index-what-is-it_003f-2"></a>BFD is a package which allows applications to use the
|
||
|
|
same routines to operate on object files whatever the object file
|
||
|
|
format. A new object file format can be supported simply by
|
||
|
|
creating a new BFD back end and adding it to the library.
|
||
|
|
|
||
|
|
<p>BFD is split into two parts: the front end, and the back ends (one for
|
||
|
|
each object file format).
|
||
|
|
<ul>
|
||
|
|
<li>The front end of BFD provides the interface to the user. It manages
|
||
|
|
memory and various canonical data structures. The front end also
|
||
|
|
decides which back end to use and when to call back end routines.
|
||
|
|
<li>The back ends provide BFD its view of the real world. Each back
|
||
|
|
end provides a set of calls which the BFD front end can use to maintain
|
||
|
|
its canonical form. The back ends also may keep around information for
|
||
|
|
their own use, for greater efficiency.
