Freestanding Updates

Games paper review

Arthur's suggestions:
(1) I put in the Slack channel
<https://cpplang.slack.com/archives/C3TK2M6HH/p1703947057425609> a while
ago Clang PR #76596 <https://github.com/llvm/llvm-project/pull/76596>, from
one Max Winkler, apparently in game dev. I don't think the PR stands much
chance of getting merged into Clang; but it might still be of interest to
SG14 folks. The issue description is very long and somewhat detailed, and
then there's more discussion/debate in the comments
<https://github.com/llvm/llvm-project/pull/76596#issuecomment-1872601156>.
(I'd actually be interested in talking to Max, but he doesn't publish his
email address on GitHub and I guess that might be on purpose.)

(2) LEWG will be seeing my P3055 "Relax wording to permit relocation
optimizations in the STL"
<https://quuxplusone.github.io/draft/d3055-relocation.html> in a telecon on
February 20th. (Related blog post.
<https://quuxplusone.github.io/blog/2024/01/02/bsl-vector-erase/>) Might
be interesting to folks who do EASTL-style containers. I'd be interested in
early feedback and/or telecon attendance.


Discussion on Embedded:
Paul's suggestions
The next meeting would then be Embedded and I would be interested in
knowing if people think a module std.freestanding is worth pursuing.
In that context I'd like to get some feedback perhaps already for the
upcoming meeting, if people have started using modules, and if so if it has
brought the promised expectations or if you are holding back if you see any
relevance in modules.

Review latest mailings:
P2532 Removing exception_ptr from the receivers concept
Based on the last meeting and the discussions here.
P2544 C++ Exceptions are becoming more and more problematic
We might want to chime in here.
/Paul
P. S. P2327 de-deprecating volatile received a "consensus" straw poll.
