`this' pointer vs. return pointer

[Mark Mitchell]

Does anyone remember what the resolution was on wehther the `this'
pointer comes before, or after, the pointer to structures returned by
value?

I don't think the document actually *says* at present.

I think the buffer pointer should come first, and the `this' pointer
should come afterwards.

This makes sense because then the rule is:

  - As a result of this language being C++, you add a `this' pointer.

  - In your back-end, you notice that you've got a return by value,
    so you add another parameter.

Doing anything else is going to be next to impossible in GCC, I
suspect.

Thoughts?
