/* This file supports the 64-bit MIPS ELF ABI.
27
 
28
   The MIPS 64-bit ELF ABI uses an unusual reloc format.  This file
29
   overrides the usual ELF reloc handling, and handles reading and
30
   writing the relocations here.  */

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