26 The MIPS 64-bit ELF ABI uses an unusual reloc format. This file

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