--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
I think this is actually two different bugs.
One where cstore is not working when there is a function call inbetween.
If I add an argument to CreateChecksum and change the first PolyMod to + t and
the second PolyMod  to * t.  the cstore optimization work.  This is recorded
now as PR 85987.

The second one is the lowering of common function calls with slightly different
arguments.  I thought I saw one asking for this one but I can't find it.
