--- Comment #16 from Jakub Jelinek <jakub at gcc dot gnu.org> --- (In reply to Marek Polacek from comment #15) > In C I don't think so, because we mostly call c_save_expr and c_fully_fold > therein would fold that expression to 0. And when we call save_expr, it's Yeah, I know that, and I think it is a serious bug. With the c_fully_fold in c_save_expr the C FE is not doing anything close to delayed folding, it folds immediately whenever we might need a save_expr, the old trees gone. So I think it would be nice to kill c_save_expr, just use save_expr, and let c_fully_fold fold SAVE_EXPR operand (just once, not many times).
