[SG5] August 24 meeting notes and next meeting

From: Hans Boehm <boehm_at_[hidden]>
Date: Tue, 24 Aug 2021 12:00:03 -0700
Attendees:
Hans Boehm, Victor Luchangco, Jens Maurer, Mike Spear, Michael Scott

The main goal was to discuss Hubert Tong's comments on P2066.

Jens Maurer had already prepared D2066R9, which he will upload for the next
mailing.
He went through the changes, which were uncontroversial in SG5.

Hubert's first question about whether it should be possible to query
whether we're in a transaction has not yet been addressed.

Mike Spear: The question was discussed in 2016.

AI: Hans to respond To Hubert.

Brief discussion of "ill-formed no diagnostic required" vs "undefined
behaviour".

Mike Spear: A student is starting to investigate clang front-end changes
required for the TS. Brief discussion about whether break and continue
should be allowed to exit a transaction. Consensus: yes.

Brief discussion of Intel and ARM support for TM. Nobody was aware of any
decision by Intel (or others) to drop support. The recent addition of
TSXLDTRK instructions suggests otherwise.

Meeting ended early.

Next scheduled meeting:

Sept. 21, 8:00 Pacific, 11:00 Eastern, 17:00 Central European
