Don't emit complete constructors for abstract classes. Also, don't emit complete destructors for abstract classes unless the destructor is virtual and thus needs to be in the vtable. llvm-svn: 131068

// RUN: %clang_cc1 %s -triple x86_64-apple-darwin10 -emit-llvm -o - | FileCheck %s
// Check that we dont emit the complete constructor/destructor for this class.
struct A {
virtual void f() = 0;
A();
~A();
};
// CHECK-NOT: define void @_ZN1AC1Ev
// CHECK: define void @_ZN1AC2Ev
Disable the optimization that skips emission of complete, non-virtual destructors of abstract classes. It's undefined behavior to actually call the destructor (e.g., via delete), but the presence of code that calls this destructor doesn't make the program ill-formed. Fixes <rdar://problem/9819242>. llvm-svn: 136180
