	The only options is to conform to the ABI.  Period.  GCC must
interact with other compilers.  If the ABI says that the values will be in
FPRs, another compiler may expect to find them there.

	I will check into this further next week, but I do not believe
that the compiler has any leeway in the implementation.  Improving code
quality is an optimization.  One should not hard-code optimizations like
this; the compiler must deduce the optimization when the information
allows it to do so.
