Hey,
thanks for these excellent minutes and the Itanium ABI PR!

A few small nits:

When I re-read this later, I'd like to be reminded that this was about
the "preprocessing assembly sources with a C++ preprocessor" use case
and the related language mode. I suggest

Likewise, this is missing the second half of the point I made and has
a small error in it:

I suggest

In the following quote

> Matthias: One of those was reported by me.
Only one of the links is to an issue (which was not reported by me).
The other one is a PR by me, which is also linked in the paper - I
believe I did point out that it's just implementation experience for
Option 3 of the paper.


Best regards,
Matthias
