Minor correction here: it was out of necessity due to ABI
restrictions for gcc intrinsic functions, not for optimization
purposes. Those restrictions may be long gone now, but it used
to be that parameters for gcc intrinsic functions ("libgcc
functions") were not allowed to be passed "by reference"; as
pointers. I've lost the details but I think I'm right to blame
the gcc intrinsics interface, not the CRIS port. (Other than me
not taking on removal of that restriction, of course.)

Certainly. I just missed this when doing the soft-fp
conversion. Thanks for being thorough.
