r256198 did

          /* POS counts from lsb, but make OFFSET count in memory order.  */
          if (BYTES_BIG_ENDIAN)
-           offset = (GET_MODE_PRECISION (is_mode) - len - pos) /
BITS_PER_UNIT;
+           offset = bits_to_bytes_round_down (GET_MODE_PRECISION (is_mode)
+                                              - len - pos);
          else
            offset = pos / BITS_PER_UNIT;

Was it correct before that?  At least it was symmetric so it *seemed* correct..
