Hello!

> cgraph_get_create_node really want cgraph_get_create_real_symbol_node,
> i.e. they are not interested in inline nodes and should get a
> standalone node instead. So this patch changes cgraph_get_create_node
> to do what cgraph_get_create_real_symbol_node currently does and

You will need patches from Teresa [1],[2] to get up to there in the
lto-profiledbootstrap.
