/* 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 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.
