31 | . (which was mostly stolen from elf32-mips.c and slightly adapted). | |
32 | . | |
33 | . - Relocation handling for REL relocs is wrong in many cases and | |
34 | . generally untested. | |
35 | . - Relocation handling for RELA relocs related to GOT support are | |
36 | . also likely to be wrong. | |
a4382ec6 | 37 | . - Support for MIPS16 is untested. |
5b6a02bc TS |
38 | . - Combined relocs with RSS_* entries are unsupported. |
39 | . - The whole GOT handling for NewABI is missing, some parts of | |
c6e90b02 | 40 | . the OldABI version is still lying around and should be removed. |
