bfd: Performing the Final Link

 
 2.17.3 Performing the final link
 --------------------------------
 
 When all the input files have been processed, the linker calls the
 '_bfd_final_link' entry point of the output BFD. This routine is
 responsible for producing the final output file, which has several
 aspects.  It must relocate the contents of the input sections and copy
 the data into the output sections.  It must build an output symbol table
 including any local symbols from the input files and the global symbols
 from the hash table.  When producing relocatable output, it must modify
 the input relocs and write them into the output file.  There may also be
 object format dependent work to be done.
 
    The linker will also call the 'write_object_contents' entry point
 when the BFD is closed.  The two entry points must work together in
 order to produce the correct output file.
 
    The details of how this works are inevitably dependent upon the
 specific object file format.  The a.out '_bfd_final_link' routine is
 'NAME(aout,final_link)'.
