What (Ada!) targets would it make a difference on? As it affects TYPE_SIZE it also affects layout (obviously), so I wonder how this can be an optimization (I assume it was intended to be one - likely for Adas fat pointer representation?) So might be a target with pointer mode bigger than Pmode (so where Pmode is a partial int mode?) Richard. > -- > Eric Botcazou
