Piotr Padlewski 9032a3fc4f [Devirtualization] MemDep returns non-local !invariant.group dependencies ... Summary: Memory Dependence Analysis was limited to return only local dependencies for invariant.group handling. Now it returns NonLocal when it finds it and then by asking getNonLocalPointerDependency we get found dep. Thanks to this we are able to devirtualize loops! void indirect(A &a, int n) { for (int i = 0 ; i < n; i++) a.foo(); } void test(int n) { A a; indirect(a); } After inlining a.foo() will be changed to direct call, even if foo and A::A() is external (but only if vtable definition is be available).
