--- Comment #1 from Christian Friedl <christian.friedl at gmx dot at> --- Disclaimer: I posted a request for help regarding this exact feature on the gcc-help list. (https://gcc.gnu.org/pipermail/gcc-help/2020-July/139110.html) After reading through the list I came to the conclusion that this is not implemented and probably a feature request would be more appropriate.
