--- Comment #2 from Peter Bergner <bergner at gcc dot gnu.org> --- (In reply to Bill Schmidt from comment #1) > I think that the MMA implementation is incompatible with -mno-fold-gimple. > We'll need to prevent that flag combination, I think. Does -mno-fold-gimple really even make sense as an option? I agree that the MMA builtins require gimple folding of builtins. One other option is to just ignore rs6000_fold_gimple (true or false) if the builtin attribute has RS6000_BTC_GIMPLE set.
