30 | /* TODO: Many things are unsupported, even if there is some code for it |
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. | |
37 | . - Support for MIPS16 is only partially implemented. | |
38 | . - Embedded PIC is only partially implemented (is it needed?). | |
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. |
