I suppose problem may be in: gcc/config/i386/i386-modes.def:#define MAX_BITSIZE_MODE_ANY_INT (128) which doesn't allow to create constants of bigger size. Changing it to maximum vector size (512) would mean we increase wide_int structure size significantly. New patterns are probably also needed. Ilya > > Richard. > >> Yuri. >> >>
