|
|
. (which was mostly stolen from elf32-mips.c and slightly adapted).
|
|||
|
|
.
|
|||
|
|
. - Relocation handling for REL relocs is wrong in many cases and
|
|||
|
|
. generally untested.
|
|||
|
|
. - Relocation handling for RELA relocs related to GOT support are
|
|||
|
|
. also likely to be wrong.
|
|||
|
|
. - Support for MIPS16 is untested.
|
|||
|
|
. - Combined relocs with RSS_* entries are unsupported.
|
|||
|
|
. - The whole GOT handling for NewABI is missing, some parts of
|
|||
|
|
. the OldABI version is still lying around and should be removed.
