--- Comment #4 from Segher Boessenkool <segher at gcc dot gnu.org> ---
That is code *size*. Code size is expected to grow a tiny bit, because of
*better* register allocation.
But we could not do make_more_copies at -Os, if that helps? (The hard register
changes themselves are required for correctness).
