So I doubt this part is going to be accepted. Please use `make "gas-abi=64" <whatever>' instead. Alternatively, please let me check if I can get some time to implement one of my to-do list goals, that is having it configurable. > @@ -580,7 +580,11 @@ > libs-$(CONFIG_SIBYTE_SENTOSA) += arch/mips/sibyte/swarm/ > load-$(CONFIG_SIBYTE_SENTOSA) := 0x80100000 > libs-$(CONFIG_SIBYTE_SWARM) += arch/mips/sibyte/swarm/ > +ifdef CONFIG_MIPS64 > +load-$(CONFIG_SIBYTE_SWARM) := 0xffffffff80100000 > +else > load-$(CONFIG_SIBYTE_SWARM) := 0x80100000 > +endif > > # > # SNI RM200 PCI I think 32-bit tools may be able to cope with 0xffffffff80100000, so you wouldn't need this conditional. Actually some 32-bit can't really cope with something like 0x80100000, grr...

E.g. I use 64-bit ELF for 64-bit DECstations, too, but others may prefer 32-bit binaries. Maciej
