After posting the patch last night I tweaked the movdf+1 and movxf+1
constraints further by adding earlyclobber to alternative three.
So instead of:
[(set (match_operand:DF 0 "nonimmediate_operand" "=f,m,!*r,!o")
it reads:
[(set (match_operand:DF 0 "nonimmediate_operand" "=f,m,!&*r,!o")
Okay to update the source tree?
