Reminder: the purpose is to co-ordinate between active contributors.
If you have support questions etc then it's best to post to llvm-dev.

We have a call each Thursday at 4pm GMT, via

I've created a shared calendar which may help in keeping track, which

The lowRISC team are at an off-site today so we won't be able to
participate as usual, but Ana Pazos has kindly volunteered to run the
meeting. There aren't many submitted topics, so it may be a short one.

Issues to discuss today include the following:
* 10.0 status
  * No outstanding backport requests or regressions we know of.
* Supporting yet-to-be-ratified extensions. Simon's patch has seen new
additions in the past week
https://reviews.llvm.org/D73891
* It may be worth discussing [RFC][TableGen/RISCV] Support combining
AssemblerPredicates with ORs https://reviews.llvm.org/D74338
* No other topics were submitted, as always, please do submit things
you'd like to discuss

Best,

Alex
