--- Comment #5 from Andrew Pinski <pinskia at gcc dot gnu.org> --- By the way this is from the email thread that added that option (https://gcc.gnu.org/ml/fortran/2019-07/msg00054.html): The code for deprecated items is still present and can sometimes be used via the -fallow-invalid-boz option. After 10.1 is released, and if I am still contributing to gfortran, I will remove the code. If someone feels strongly that a previous undocument extension should be retain, feel free to fix it after I commit the patch. I think I've weighed the pros and cons, and have made prudent decision of want to deprecate. ---- CUT ---- So using an undocumented extension .... Basically BOZ is finally standardized in Fortran2018 and the NAS benchmark could be re-written in a standard format instead ...
