It should be sufficient. Do you have a testcase to show otherwise?
broadcast_op is referenced only by

              broadcast_op.type = bcst_type;
              broadcast_op.operand = this_operand;
              broadcast_op.bytes = 0;
              i.broadcast = &broadcast_op;

broadcast_op.bytes is initialized to 0 when broadcast_op.type
is set.
