Do not be so sure of this "of course", for instance GCC:
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=22141
and last time I tried Clang (LLVM) was worse (mov $4,ecx; rep mov stosb).

I have to say that older compiler version were copying fields of structure more efficiently, because they were not optimised to compile
C++ code which may trigger constructor for each fields of the structure.
