--- Comment #5 from Jan Hubicka <hubicka at gcc dot gnu.org> ---
We do not inline CwiseNullaryOp because it uses comdat local symbols.
This is because we do split the function and the .part stays local.
At least we should recompute if function calls comdat local after comdat local
function is inlined.
