[llvm-dev] Should we have a "GPU working group"?

[Lei Zhang via llvm-dev]

+1. There are certainly efforts that need broad collaboration among various
interest parties; they would benefit from more interactive discussions to
have everybody on the same page. What immediately jumps into my mind
include how we can push to have unified/better SPIR-V support in LLVM
proper / cross LLVM/MLIR, etc. It's a big one that I'd assume will take a
long time to unfold and will have back and forth. Having a place to discuss
will actually make sure we put efforts towards it (or at least have plans
and revisit periodically). There are certainly many other topics to discuss
too, as said by Johannes. I think this is a great idea.

Thanks,
Lei
