;; Tests callsite context graph generation for call graph containing indirect
;; calls. Currently this should result in conservative behavior, such that the
;; indirect call receives a null call in its graph node, to prevent subsequent
;; cloning. Also tests graph and IR cloning.
;;
;; Original code looks like:
;;
;; char *foo() {
;;   return new char[10];
;; }
;; class A {
;; public:
;;     virtual char *x() { return foo(); }
;; };
;; class B : public A {
;; public:
;;     char *x() final { return foo(); }
;; };
;; char *bar(A *a) {
;;   return a->x();
;; }
;; int main(int argc, char **argv) {
;;   char *x = foo();
;;   char *y = foo();
;;   B b;
;;   char *z = bar(&b);
;;   char *w = bar(&b);
;;   A a;
;;   char *r = bar(&a);
;;   char *s = bar(&a);
;;   memset(x, 0, 10);
;;   memset(y, 0, 10);
;;   memset(z, 0, 10);
;;   memset(w, 0, 10);
;;   memset(r, 0, 10);
;;   memset(s, 0, 10);
;;   delete[] x;
;;   delete[] w;
;;   delete[] r;
;;   sleep(10);
;;   delete[] y;
;;   delete[] z;
;;   delete[] s;
;;   return 0;
;; }
;;
;; Code compiled with -mllvm -memprof-ave-lifetime-cold-threshold=5 so that the
;; memory freed after sleep(10) results in cold lifetimes.
;;
;; Compiled without optimization to prevent inlining and devirtualization.
;;
;; The IR was then reduced using llvm-reduce with the expected FileCheck input.
