this shouldn't be a bother.  you should be able to use the doubleword
load and store instructions (or the block byte moves if you want) to
move floats and doubles.

the only place you have to watch out for is

	if (f1 = f2)
		...

or some other conditional context.  you have to use the floating point
moves or a floating point test to properly set the condition codes.
