[pinskia at gcc dot gnu dot org]

------- Comment #4 from pinskia at gcc dot gnu dot org  2006-02-13 15:37 -------
Testcase for the mainline:
typedef struct Foo { int a; int b; }Foo;

Foo foo(Foo first, Foo last, bool ret_first)
{
  Foo t;
  Foo *t1 = (ret_first ? &first : &last);
  first.a = 2;
  last.b = 3;
  t.a = t1->a;
  t.b = t1->b;
  t.a += first.a;
  t.b += last.b;
  return t;
}
