Yea, I pulled that down, now I'm getting some strangeness from 
binutils.  It's complaining about perfectly valid instructions..., 
Ugh.  (2.11.2 & CVS)

Explain ..., how does this work?

Sure, clearly.  I'll try to get some broken test cases with present 
CVS.  As far as MIPS16 documentation, the best I know is the VR4181 
documentation includes a pretty good instruction by instruction 
mips16<->mips32 overview.

(I'd give you a direct link, but their site doesn't work well with 
that, it's under Microprocessors and the data sheet for the VR4181)

Thanks,
