That's not that difficult – as Thomas K has written shortly before you filled this PR: https://gcc.gnu.org/pipermail/fortran/2020-April/054270.html "... and also caused a regression, see PR 94788. Reverted on trunk so far, so the upcoming release is OK. This will still take some more work, I suppose..."
