Hi again,
dietlibc/mips64 now mostly works on t2/trunk:HEAD:
root@octane:/usr/embutils# ./uname -a
Linux octane 2.6.36 #1 Thu Dec 30 06:53:35 CST 2010 mips64
root@octane:/usr/embutils# ./echo 123 abc
123 abc
Some syscalls arguments still get mangled, though. However, many to most
already work. Need to further dive thru the syscall assembly :-)
Regards,
René
