--- Comment #17 from Jan Hubicka <hubicka at gcc dot gnu.org> ---
Unforutnately it is a bit difficult without Haswell machine. Would be possible
to profile it and post the difference in internal loops?
Possibly the target option node is not streamed fully and some flags are
getting lost, though I do not see how that can happen...
