--- Comment #11 from Jonathan Wakely <redi at gcc dot gnu.org> ---
With current trunk the two functions compile to identical code even at -O1,
just returning 9. But that's only because I made char_traits<char8_t>::length
use strlen.
Before r15-6990-g44d21551362f90 the code for g() was very branchy and included
branches that allocate memory, and so can throw bad_alloc. After that commit,
the allocations and exceptional path are gone in g(), but we still have two
calls to deallocate with _ZdlPvm (which are unreachable because we don't have
anything to deallocate!)
So things are much better on trunk, but g() is not optimal yet. So I guess we
should keep it open.
