--- Comment #8 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
I think this changed with r192246.  And the question is what we want for the
debugging experience.  Not emitting location info for the expressions expanded
from the default arguments is strange, and it is something that is evaluated on
the caller side, not on the callee side.
