If frontend optimization is preferred, I'll step out of the way.
Nevertheless, one also need to address issues like:
% cat maxmin.f90
program p
implicit none
print *, min (2.0, 1.d0)
print *, min (2.d0, 1.0)
print *, kind (min (2.0, 1.d0))
print *, kind (min (2.d0, 1.0))
end program p
% gfc-11 maxmin.f90 && ./a.out
1.00000000
1.0000000000000000
4
8
The only compiler I found having the same is PGI/NVIDIA.
OTOH ifort (and similarly sunf95, g95(!)) result in the expected:
1.00000000000000
1.00000000000000
