Yes. I suppose it's ok to re-order side-effects lhs, rhs to rhs, lhs?
Otherwise you'd need to do sth like
op0 = save_expr (op0);
*expr_p = build2 (COMPOUND_EXPR, TREE_TYPE (*expr_p),
op0,
build2 (COMPOUND_EXPR, TREE_TYPE (*expr_p),
build_fold_addr_expr (op1), op0));
(which may or may not work or be a good idea with zero-size aggregate op0)
