--- Comment #5 from Francois-Xavier Coudert <fxcoudert at gcc dot gnu.org> --- (In reply to Jerry DeLisle from comment #4) > I was looking at this yesterday. It is implemented in ieee_arithmetic.F90 > and I think can be done with generic type bound procedures. There's also a simplifier for the compile-time version. > According to > the comment in the code, the ieee_arithmetic.F90 file is generated, but it > is not clear to me where the generation of the .F90 is specified. It is not automatically generated.
