I'd like a pta type person (or anyone that has an opinion on the change) to review/comment on this…  Surely we have at least 1 person that still works in that area around here…

This is the type of change:

Index: gcc.dg/tree-ssa/pta-escape-2.c

I'd say rather than just disabling the scan for
keeps_null_pointer_checks you should add
appropriate scanning for those targets as well (I expect you just
don't see the 'NULL's in the points-to sets).

Well, for gcc.dg/ipa/ipa-pta-14.c, which doesn't have NONLOCAL otherwise,
you instead see NONLOCAL.

Please find attached the amended patch.

I have verified that this gets the new expected PASSes for atmega128-sim.

Yes.  On those targets NULL == NONLOCAL (0 is just another global address).

Ok.
