linux-user: Rewrite __get_user/__put_user with __builtin_choose_expr The previous formuation with multiple assignments to __typeof(*hptr) falls down when hptr is qualified const. E.g. with const struct S *p, p->f is also qualified const. With this formulation, there's no assignment to any local variable.
