--- Comment #30 from Dominique d'Humieres <dominiq at lps dot ens.fr> --- I have submitted a patch some time ago at https://gcc.gnu.org/ml/gcc-patches/2017-11/msg00939.html Mike asked for some changes and I got distracted before being able to fulfill the requests. I can do it in the coming week, but if someone want to do it sooner, there is no problem.
