--- Comment #2 from Richard Biener <rguenth at gcc dot gnu.org> ---
The issue is that IPA-PTA sees main () still as calling f but the cgraph
has it calling f.constprop.0.  For some reason the IPA-CP transform has
not been applied to main () (yet?).  In .simdclone I see a call to
f.constprop.0.

Honza?  Martin?

Late IPA passes need all regular IPA transforms applied and clones
materialized.
