Hi all,

I don't have much to update on today, so I'm going to cancel today's meeting. The next one is scheduled for Monday April 5th. The day may be a holiday for some folks, so please let me know if you would prefer to reschedule for a week prior or after. Please add the topics or questions you would like to bring up to the agenda <https://docs.google.com/document/d/1-uEEZfmRdPThZlctOq9eXlmUaSSAAi8oKxhrPY_lpjk/edit#heading=h.nhty409us69h> .

Let me also use this opportunity to highlight an exceptional milestone, in removing the MemDepAnalysis <https://reviews.llvm.org/D97877> implementation of DSE, after landing the MemorySSA based implementation. Kudos and thank you to Florian, Nikita and all the folks involved in the reviews.

Best, Alina

Hi all,

The next meeting was set for today, 10:30 Pacific Time/5:30pm UTC (in about 3h). Given the low agenda topics and closeness to the holidays, I'll go ahead and cancel it. If you'd like to talk to me, feel free to email me and I'll be happy to join the meet. The first meeting in 2021 is set for January 11th, at the same time. Happy holidays!

The agenda includes progress on the topics discussed last time (meeting notes in the doc), and open discussions and questions from those who join. Again, this is an open meeting, all are welcome. Looking forward to talking to you! Best, Alina

I thought the tutorial was a very useful high-level view. I think there's more depth that can be added, but we were missing a longer MemorySSA video tutorial and having this added to youtube (after post-production) will be great. It was very much appreciated that you and Simon worked on this! Yes, I have a few items to add to the documentation, and this video is one of them once available. Beginners are welcome to the open meetings, it's meant to be a forum to ask questions and to sync with folks that may work on similar items. Even for the items that I put in the doc, some have been in talks for a long time, but only started being worked on more recently. So having more people learn about MemorySSA and contribute or sync-up and pick up items to help out with, will be awesome. Best, Alina

Here are some questions: Is this meeting relevant to beginners in MemorySSA ? If yes, one thing we could discuss in the meeting is where a beginner could start contributing ? (e.g. does anyone need help on the ongoing efforts mentioned in the gdoc?). Another thing that might be helpful: In this year's LLVM conf, Simon and me did a tutorial related to dependence analysis in LLVM: https://whova.com/portal/webapp/llvm202010/Agenda/1162352 Half of the tutorial is about MemorySSA. We would be glad to know the opinion of core developers of MemorySSA on that. If you find it good, we can reference it in this doc: https://llvm.org/docs/MemorySSA.html (Now that I'm thinking about it, I should've opened a diff instead of mentioning it here but anyway, you may find something useful to discuss about it in the meeting as well, e.g. anything missing).

For those who participated, please feel free to add items I may have missed into the document and cc folks that may not be on the llvm-dev list. It seems useful to catch-up periodically to sync or make progress on existing work related to MemorySSA or discuss new uses. I opened up this doodle poll <https://doodle.com/poll/xm8aerdgbtt5qsgd> to set up a time that's best suited for those interested to participate. I've set a placeholder recurring meeting to monthly for which I'll adjust the day/time based on the doodle poll results, and we can adjust frequency based on how useful folks find it. The meeting information can be found in the above google doc. Please let me know if you have additional feedback or questions. Best, Alina
