I wrote a safer version of this for PR52436:


        case BIT_FIELD_REF:
-         return NULL_TREE;
+         {
+           HOST_WIDE_INT this_off = TREE_INT_CST_LOW (TREE_OPERAND (exp, 2));
+           if (this_off % BITS_PER_UNIT)
+             return NULL_TREE;
+           byte_offset += this_off / BITS_PER_UNIT;
+         }
+         break;
