Remove an old workaround that was kept around for ABI-compatibility on x86-64 between different LLVM versions. This means LLVM r67588 is required if you want to compile for x86-64, otherwise the backend will assert when you try to return e.g. struct { int i; char c; } from a function. (In particular, this is no longer compatible with LLVM 2.5) It also means that any code returning small structs on x86-64 will probably need to be recompiled in order to be linkable to code compiled with this change.

module mini.nested14;

extern(C) int printf(char*, ...);

class C
{
  void foo()
  {
    void bar()
    {
       car();
    }

    bar();
  }

  void car()
  {
    printf("great\n");
  }
}

void main()
{
  scope c = new C;
  c.foo();
}
