Thank you, Matthias! Sorry for the delayed response. All suggestions applied with some editorial discretion; details below. Let me know if further edits are desired.

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

A few small nits:

Matthias: I don't think we need to worry about other tools, they can invoke the preprocessor with the options needed.

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

Matthias: I don't think we need to worry about other tools or the assembly-with-cpp language mode, they can invoke the preprocessor with the options needed.

Applied as suggested:

> Matthias: I don't think we need to worry about other tools or the assembly-with-cpp language mode; users can invoke the preprocessor with the options needed.

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

Matthias: Linux .S sources depend on $ not being a digit, but it can be worked around with additional macro expansion.

I suggest

Matthias: Linux .S sources depend on $ not being a nondigit, but it can be worked around with additional macro expansion. Linux does however also depend on $ being treated as nondigit for some of their .c sources.

Thank you! I recall being confused about that error when editing after the meeting and assumed I misunderstood something.

In the following quote

Aaron: I think there were some recently reported issues involving $ in the preprocessor. [...]
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.

Applied as:

Tom.

Best regards,
Matthias

The consistent behavior across compilers that use Itanium mangling inspired me to submit a PR to the Itanium ABI to add $ to the <identifier> non-terminal.
