	This looks like another PIC/GOT problem.  movdf is trying to
reference a symbol described by a LO_SUM.  I suspect that the "address"
needs to be split / legitimized somehow.  Probably movsf and movdf
define_expand patterns need some of the mechanism employed in movsi for
handling these compound addresses, but I am not sure.
