Well, not for unions anyway. > I think we should somehow compute the size of the CONSTRUCTOR and compare > it with int_size_in_bytes (TREE_TYPE (object))...? For unions, that may be what we have to do. With any luck, the element being initialized will be the largest element of the union, which would mean we wouldn't have to emit the clear. For structures, this would mean that any structure with holes would get cleared. Which would clearly pessimize a very common case. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=19515
