32/* TODO: Many things are unsupported, even if there is some code for it
33 . (which was mostly stolen from elf32-mips.c and slightly adapted).
34 .
35 . - Relocation handling for REL relocs is wrong in many cases and
36 . generally untested.
37 . - Relocation handling for RELA relocs related to GOT support are
38 . also likely to be wrong.
a4382ec6 39 . - Support for MIPS16 is untested.

TS
40 . - Combined relocs with RSS_* entries are unsupported.
41 . - The whole GOT handling for NewABI is missing, some parts of
c6e90b02 42 . the OldABI version is still lying around and should be removed.
