DESCRIPTION
|

If @var{output_bfd} is supplied to this function, the generated

image will be relocatable; the relocations are copied to the

||||
output file after they have been changed to reflect the new
|
||||
state of the world. There are two ways of reflecting the
|
||||
results of partial linkage in an output file: by modifying the
|
||||
output data in place, and by modifying the relocation record.
|
||||
Some native formats (e.g., basic a.out and basic coff) have no
|
||||
way of specifying an addend in the relocation type, so the
|
||||
addend has to go in the output data. This is no big deal
|
||||
since in these formats the output data slot will always be big
|
||||
enough for the addend. Complex reloc types with addends were
|
||||
invented to solve just this problem.
