<h5 class="subsubsection">2.17.3.1 Information provided by the linker</h5>
|
||
|
|
|
||
|
|
<p>Before the linker calls the <code>_bfd_final_link</code> entry point,
|
||
|
|
it sets up some data structures for the function to use.
|
||
|
|
|
||
|
|
<p>The <code>input_bfds</code> field of the <code>bfd_link_info</code> structure
|
||
|
|
will point to a list of all the input files included in the
|
||
|
|
link. These files are linked through the <code>link_next</code> field
|
||
|
|
of the <code>bfd</code> structure.
|
||
|
|
|
||
|
|
<p>Each section in the output file will have a list of
|
||
|
|
<code>link_order</code> structures attached to the <code>map_head.link_order</code>
|
||
|
|
field (the <code>link_order</code> structure is defined in
|
||
|
|
<code>bfdlink.h</code>). These structures describe how to create the
|
||
|
|
contents of the output section in terms of the contents of
|
||
|
|
various input sections, fill constants, and, eventually, other
|
||
|
|
types of information. They also describe relocs that must be
|
||
|
|
created by the BFD backend, but do not correspond to any input
|
||
|
|
file; this is used to support -Ur, which builds constructors
|
||
|
|
while generating a relocatable object file.
