;; 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. ;;
