__ld_insert_mlink_relocs |
__ld_insert_mlink_relocs inserts relocs in a compressed format known
from mlink. For more information on inserting and processing relocs, see
__ld_insert_kernel_relocs.
In the following format description, offset refers to the difference
in words (half of the difference in bytes) between the start of this reloc
and the start of the previous reloc. If there is no previous reloc (i.e. for
the first reloc), offset is the distance in words between this reloc
and the symbol __ld_mlink_relocs_ref
. This symbol must be
exported to be found. If it is not found, the entry point is used instead
(see __ld_entry_point).
- For each relocation entry...
- Any of the following, whichever fits:
- For 0 <= offset < 128: 1 byte:
0x80 + offset
- For 128 <= offset < 16384: 2 bytes:
offset / 128, 0x80 + (offset % 128)
- For 16384 <= offset < 2097152: 3 bytes:
offset / 16384, (offset % 16384) / 128,
0x80 + (offset % 128)
- Anything higher isn't interesting for us because of the 64 KB
file size limit.
- 1 byte: 0
Note: The limitations of
__ld_insert_kernel_relocs also
apply to this insertion.
