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();
};
FileCheck's -LABEL cannot be combined with -NOT or -DAG llvm-svn: 201476

Output destructors and constructors in a more natural order. With this patch we output the in the order C2 C1 D2 D1 D0 Which means that a destructor or constructor that call another is output after the callee. This is a bit easier to read IHMO and a tiny bit more efficient as we don't put a decl in DeferredDeclsToEmit. llvm-svn: 196784
