Then why do you need this change? > - TYPE_SIZE (type) = bitsize_int (GET_MODE_BITSIZE (TYPE_MODE (type))); > + TYPE_SIZE (type) = bitsize_int (GET_MODE_PRECISION (TYPE_MODE > (type))); TYPE_SIZE_UNIT (type) = size_int (GET_MODE_SIZE (TYPE_MODE > (type))); break; What are GET_MODE_BITSIZE and GET_MODE_PRECISION for PSImode? > If a type is 17-20 bits, PSImode is chosen. If it's 21 bits or > larger, SImode is chosen. If it's 16 or fewer bits, HImode is chosen. Size or precision? That's the crux of the matter. -- Eric Botcazou
