[llvm-dev] MemorySSA LLVM-dev meeting notes and upcoming meetings

Fri Jun 4 16:07:41 PDT 2021

Hi all,

I will not be available next Monday, June 7th for the MemorySSA meeting. I
had to cancel that and I also rescheduled the July time slot earlier to
June 28th, as the US located participants will have federal holiday on the
previous allotted day. I'm hoping this is a good time to catch up. Please
let me know if you have other constraints and I can accommodate those.
Please see the calendar entry
<https://calendar.google.com/calendar/embed?src=c_1mincouiltpa24ac14of14lhi4%40group.calendar.google.com>
and
minutes document
<https://docs.google.com/document/d/1-uEEZfmRdPThZlctOq9eXlmUaSSAAi8oKxhrPY_lpjk/edit#heading=h.nhty409us69h>
for
more details.

Thank you,
Alina
