/* This file supports the 64-bit MIPS ELF ABI.
The MIPS 64-bit ELF ABI uses an unusual reloc format. This file
overrides the usual ELF reloc handling, and handles reading and

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