--- Comment #5 from Jakub Jelinek <jakub at gcc dot gnu.org> 2010-11-19 08:46:46 UTC --- Actually, reading that comment again it, the conversion warnings are probably emitted during convert_for_assignment and thus the earlier c_fully_fold is needed. Perhaps we need another c_fully_fold if convert_for_assignment returned something different from the passed argument, or remove the if (code != MODIFY_EXPR) guard for c_fully_fold_internal on the RHS of a MODIFY_EXPR.
