/* 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
   writing the relocations here.  */

/* 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 only partially implemented.
 .   - Embedded PIC  is only partially implemented (is it needed?).
 .   - 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 shold be removed.
