* expmed.c (store_bit_field): Make the SUBREG code adjust bitnum. Set bitpos and offset later in the function. Do nothing if the target is a register and if the bitfield lies completely outside that register. (extract_bit_field): Make the same SUBREG, bitpos and offset changes here. Return an uninitialised register if the source value is stored in a register and the bitfield lies completely outside that register. From-SVN: r94677
