------- Comment #10 from rguenth at gcc dot gnu dot org 2007-06-20 15:16 -------
trunk has the same problem, but different constraints:
Constraints:
ANYTHING = &ANYTHING
READONLY = &ANYTHING
INTEGER = &ANYTHING
barptr = &bar1
barptr.0_1 = barptr
Points-to sets
NULL = { }
ANYTHING = { ANYTHING }
READONLY = { ANYTHING }
INTEGER = { ANYTHING }
barptr = { bar1 }
bar1 = { }
barptr.0_1 = same as barptr
