; This test is to verify that PGO runtime library calls get created with the
; appropriate operand bundle funclet information when an indirect call
; was marked with as belonging to a particular funclet.

; Test case based on this source:
;  extern void may_throw(int);
;
;  class base {
;  public:
;    base() : x(0) {};
;    int get_x() const { return x; }
;    virtual void update() { x++; }
;    int x;
;  };
;
;  class derived : public base {
;  public:
;    derived() {}
;    virtual void update() { x--; }
;  };
;
;  void run(base* b, int count) {
;    try {
;      may_throw(count);
;    }
;    catch (...) {
;      // Virtual function call in exception handler for value profiling.
;      b->update();
;    }
;  }
