Trying to fix the 'T' constraint was in fact the approach I tried first.
Hopefully, I didn't do it correctly. In my original patch, the 'A'
contraint was placed before the 'T' constraint because it accepted address
loads into FP registers. If your 'T' fixes works and it proves necessary
to handle address loads into FP registers, possibly '!' could be used
to severely disparage the 'A' FP alternative.
