overrides the usual ELF reloc handling, and handles reading and

31 |

/* TODO: Many things are unsupported, even if there is some code for it

34 |
|
|
. (which was mostly stolen from elf32-mips.c and slightly adapted).
|
35 |
|
|
.
|
36 |
|
|
. - Relocation handling for REL relocs is wrong in many cases and
|
37 |
|
|
. generally untested.
|
38 |
|
|
. - Relocation handling for RELA relocs related to GOT support are
|
39 |
|
|
. also likely to be wrong.
|
40 |
|
|
. - Support for MIPS16 is untested.
|
41 |
|
|
. - Combined relocs with RSS_* entries are unsupported.
|
42 |
|
|
. - The whole GOT handling for NewABI is missing, some parts of
|
43 |
|
|
. the OldABI version is still lying around and should be removed.
