--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
The issue here is that IPA "nonlocal" (during propagation) means not unit-local
while "nonlocal" in non-IPA PTA (and in the SSA name points-to info) means
not function-local. We "mix" both when translating IPA "nonlocal" to actual
points-to info.
The solution is to define a single terminology that covers both PTA and
IPA PTA which means separating IPA_NONLOCAL, NONLOCAL, IPA_ESCAPED and ESCAPED
and accordingly adjust pt query helpers.
We already have the global ipa_escaped set but don't yet have ipa_nonlocal
in struct pt_solution.
