This module writes out the final image by reading sections from the
|
|
input files, relocating them and writing them out
|
|
|
|
There are two main paths through this module, one for normal
|
|
operation and one for partial linking.
|
|
|
|
During normal operation, raw section data is read along with the
|
|
associated relocation information, the relocation info applied and
|
|
the section data written out on a section by section basis.
|
|
|
|
When partially linking, all the relocation records are read to work
|
|
out how big the output relocation vector will be. Then raw data is
|
|
read, relocated and written section by section.
