--- Comment #17 from sudi at gcc dot gnu.org --- Since this looks like a pretty invasive problem, according to my discussions with Wilco and Kyrill, I think I will try to propose a smaller, but temporary fix using the ?s and special casing 32 for this PR (which could go in sooner). I will also open a new PR to handle this at the expand phase and clean up the code aimed at gcc 9.
