--- Comment #8 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Actually RSO setting might come from the gimplifier:
/* For calls that return in memory, give *to_p as the CALL_EXPR's
return slot so that we don't generate a temporary. */
if (!CALL_EXPR_RETURN_SLOT_OPT (*from_p)
&& aggregate_value_p (*from_p, *from_p))
{
...
In the case of x86_64, Foo is not aggregate_value_p.
Which does a target hook:
if (targetm.calls.return_in_memory (type, fntype))
return true;
reg = hard_function_value (type, 0, fntype, 0);
and how it returns too.
So yes this is a dup of bug 82705.
