32 . (which was mostly stolen from elf32-mips.c and slightly adapted).
33 .
34 . - Relocation handling for REL relocs is wrong in many cases and
35 . generally untested.
36 . - Relocation handling for RELA relocs related to GOT support are
37 . also likely to be wrong.

40 . - The whole GOT handling for NewABI is missing, some parts of
c6e90b02 41 . the OldABI version is still lying around and should be removed.
