--- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Seems it is like
tree offvar;
tree running_off;
if (!costing_p)
{
... (..., &offvar, ...);
}
running_off = offvar;
for (...)
{
if (costing_p)
{
...
continue;
}
use running_off;
}
So, all wrong it does is that it is copying possibly uninitialized value
unconditionally to something that will not be used unless it is initialized.
Agreed we should either initialize offvar to NULL_TREE or rework in some other
way.
