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 2011-05-08 17:25:05 +00:00			`// RUN: %clang_cc1 %s -triple x86_64-apple-darwin10 -emit-llvm -o - \| FileCheck %s`

CHECK-LABEL-ify some code gen tests to improve diagnostic experience when tests fail. llvm-svn: 188447 2013-08-15 06:47:53 +00:00			`// CHECK-LABEL: define void @_ZN1AC2Ev`

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 2013-12-09 14:51:17 +00:00			`// CHECK-LABEL: define void @_ZN1AD1Ev`
