Oops, let's try that again...

I tried this on my board.  I'm running 2.2.14 the SBC8260 and some other
hardware.  I ran the code you posted and it produced exactly the results
that it should have.

The word I have from Motorola is that rev A.1 8260's have a full FPU,
whereas prior version do not.  My experiences confirm this.

Also, I don't cross compile;  I use a G3 MAC running linux.  I wonder if
this makes a difference?


Neil.
