--- Comment #8 from Francois-Xavier Coudert <fxcoudert at gcc dot gnu.org> ---
So the calculation inside __gfortran_erfc_scaled_r16 is correct, but the result
is printed incorrectly. Can you try this:

program test
  real(kind=16) :: x
  x = 10.9_16 ; print *, erfc_scaled(x)
  x = 11.9_16 ; print *, erfc_scaled(x)
  x = 12.0_16 ; print *, erfc_scaled(x)
  x = 12.1_16 ; print *, erfc_scaled(x)
  x = 13.1_16 ; print *, erfc_scaled(x)
  x = 14.1_16 ; print *, erfc_scaled(x)
end program test

Also, can you confirm that binary128 is not the same as long double on ia64?

(I've sent a request to reopen my old account on the compile farm… If this
drags out, I'll investigate on my own there. But for now, I don't have access
to an ia64.)
