Looking for early paper about compiling object-oriented code

I remember reading a paper a long time ago that talked about object-oriented programming. I believe that this was from the ear开发者_高级运维ly 1980s or perhaps even before then.

This was at the time when object-oriented programming was still done through pre-processors, and one thing that stuck with me is this: it argued that you could write code in either procedural or object-oriented fashion, and after preprocessing/compiling, you would end up with the exact same machine code.

Does anybody know which paper I'm talking about?

Bjarne Stroustrup wrote a paper more or less along the same lines. I kind of doubt it's the paper you're thinking of though, since it wasn't published until 1999, but perhaps it's useful anyway.
