No, surely you don't want to do that! You really need a movdi pattern - even more so if there are no natural DImode-sized registers, as gcse can get terribly confused by bad reg_equal notes if you don't. See e.g.: http://gcc.gnu.org/ml/gcc/2003-04/msg01397.html http://gcc.gnu.org/ml/gcc/2004-06/msg00993.html cheers, DaveK -- Can't think of a witty .sigline today....
