32 1.1 christos . (which was mostly stolen from elf32-mips.c and slightly adapted).
33 1.1 christos .
34 1.1 christos . - Relocation handling for REL relocs is wrong in many cases and
35 1.1 christos . generally untested.
36 1.1 christos . - Relocation handling for RELA relocs related to GOT support are
37 1.1 christos . also likely to be wrong.
38 1.1 christos . - Support for MIPS16 is untested.
39 1.1 christos . - Combined relocs with RSS_* entries are unsupported.
40 1.1 christos . - The whole GOT handling for NewABI is missing, some parts of
41 1.1 christos . the OldABI version is still lying around and should be removed.
