--- Comment #31 from Jan Hubicka <hubicka at gcc dot gnu.org> ---
Having a testcase is great. I was just playing with crafting one.
I am still concerned about value ranges in ipa-prop's jump functions.
Let me see if I can modify the testcase to also trigger problem with value
ranges in ipa-prop jump functions.

Not streaming value ranges is an omission on my side (I mistakely assumed w=
e do
stream them).  We ought to stream them, since otherwise we will lose propag=
ated
return value ranges in partitioned programs, which is pity.=
