   Does purge_addressof_1 restrict itself to working for that case only when
   dealing with floatign point modes?

No it doesn't.  Anyways, if Richard was interested in the case where
they are the same size, his new code should have checked for that
specifically.  The current stuff, as we saw, opened up pandoras box by
sending byte and halfword sized integral extractions of float regs to
the bit field rtl emitters...
