/* PR 15262. Similar to pr15262-1.c but with no obvious addresses being taken in function foo(). Without IPA, by only looking inside foo() we cannot tell for certain whether 'q' and 'b' alias each other. */ struct A { int t; int i; }; struct B { int *p; float b; }; float X; foo (struct B b, struct A *q, float *h) { X += *h; *(b.p) = 3; q->t = 2; return *(b.p); } main() { struct A a; struct B b; b.p = &a.t; if (foo (b, &a, &X) == 3) abort (); return 0; }
