[Bug tree-optimization/26258] [4.1/4.2 Regression] Wrong alias information for struct

[pinskia at gcc dot gnu dot org]

------- Comment #5 from pinskia at gcc dot gnu dot org  2006-02-13 15:42 -------
For the testcase in comment #4:
Points-to analysis

Constraints:
t1_1 = &first
t1_1 = &last

Solving graph:

Points-to sets
t1_1 = { first last }

Pointed-to sets for pointers in foo

t1_1, name memory tag: NMT.17, is dereferenced, points-to vars: { SFT.4 SFT.6 }


----

t1_1 is wrong in "Pointed-to sets for pointers in foo".  maybe we forget to add
all the SFT's or something.
