//===---------------------------------------------------------------------===//
clang -O3 fails to devirtualize this virtual inheritance case: (GCC PR45875)
Looks related to PR3100
struct c1 {};
struct c10 : c1{
virtual void foo ();
};
struct c11 : c10, c1{
virtual void f6 ();
};
struct c28 : virtual c11{
void f6 ();
};
void check_c28 () {
c28 obj;
c11 *ptr = &obj;
ptr->f6 ();
}
//===---------------------------------------------------------------------===//
We compile this:
int foo(int a) { return (a & (~15)) / 16; }
