| <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> |
| <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> |
| <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. |
