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