If I recall correctly: before your commit, both > the host compiler with offloading configured and a compiler not configured > for offloading folded it to a constant. But with reverting, only a compiler > configured for offloading folds it as it calls the folding function twice > while without offloading configured, it is old called once. I (still) don't follow. Could you please provide a concrete test case and actual vs. expected outcome.
