Double-precision square root.  What are the instructions immediately before 
and after it?

That certainly should be supported.  I think you will need to instrument NWFPE 
a bit with printk's to find out why it's going wrong.  There were a couple of 
versions of the emulator where I ill-advisedly disabled SQT (under the 
impression gcc never generated it) but I assume you aren't using one of these.
