mips and proprietary instructions

[JB]

Hi all,

I am using the realtek SDK which ships with precompiled binary versions 
of uClibc 0.9.26.  I am attempting to get some version iproute2 working 
on my radio.  After compiling tc, running it on the radio causes a 
segfault.  At first I had a hard time figuring out where it was coming 
from but eventually discovered it was a problem with the dl* system calls.

I read that 0.9.27 and greater have improved that part of the library.  
The version of gcc in the realtek SDK is 3.3.3.  I figured I would be 
better off upgrading to a newer version of the library than rewriting an 
older version tc in iproute2.

When it goes to compile memcpy.S the compiler gives an error containing 
"unrecognized opcode" when it encounters those instructions.  I have 
done some web searching and I understand there is a very round about way 
to emulate the same instructions with a lengthy series of other 
instructions but I am not very familiar with MIPS assembly.

Has anyone else seen this problem?  How have you dealt with it?

Thanks for any info on this, I've been at for quite a while!
