PR middle-end/37248 * fold-const.c (make_bit_field_ref): Change bitpos and bitsize arguments to HOST_WIDE_INT. If type has different signedness than unsignedp or different precision from bitsize, create the right type for BIT_FIELD_REF and cast to type. (fold_truthop): Change first_bit and end_bit to HOST_WIDE_INT. Revert: 2008-03-05 Richard Guenther <rguenther@suse.de> PR c++/35336 * fold-const.c (fold_truthop): Remove code generating BIT_FIELD_REFs of structure bases. (fold_binary): Likewise. (make_bit_field_ref): Remove. (optimize_bit_field_compare): Remove.
