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