| 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. |
