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. | |

5b6a02bc TS |
39 | . - Combined relocs with RSS_* entries are unsupported. |
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. |
