--- Comment #19 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Diffing the -fdump-{tree,ipa}-all-alias dumps from r14-5108 and r14-5109,
085i.fnsummary still looks good (the 2/4/8 in the ranges corresponds to whether
it is in 16/32/64 suffixed/infixed function).
But the inline dump already contains presumably bogus

hunks, the return in those cases looks still right, but the length before
memcpy looks wrong.
