...from the community: Legalization of non-power-of-2 types: https://reviews.llvm.org/D30529 TableGen for the instruction selector (last pass in the GlobalISel pipeline): https://reviews.llvm.org/D31418 and the rest of its stack We have also set up a sort of scratchpad document here: https://goo.gl/IS2Bdw At the moment it contains mostly notes from the BoF and a few other emails. The intention is to centralize any hot topics related to GlobalISel there, so people can keep track of what the current status is and what problems are being tackled at the moment in the community. If people feel it would...

...h and it doesn't really need to be limited only to GlobalISel, it looks like it might be a good idea for TableGen in general Also, Eric Cristopher has started a discussion on the GlobalISel accessors [8]. If I missed anything, please feel free to bring it up!

...lISel by default. I'm thinking we may need to add a smarter way to lower switch statements rather than just a cascaded sequence of conditional branches. Sounds optimization-ish to me.

...31080 seems promising, I've been wanting to take a look, hoping we can use that to emit an optimized lowering. I'm not sure we want that at O0 though (even if only for FastISel+DAGISel parity). > I'll try to add the above content to the document Diana created at > https://goo.gl/IS2Bdw too. Thanks for the investigation! These are also some of the biggest problems I've seen (in particular the FP regbanks). I'll make sure I find the time to file bugs for all the other issues I'm aware of.

I've kicked off a run to compare "-O0 -g" versus "-O0 -g -mllvm -global-isel -mllvm -global-isel-abort=2". I've selected the test-suite (albeit a version which is a couple of months old now) and a few short-running proprietary benchmarks to get data back quickly for an initial feel of where things are. This was running on Cortex-A57 AArch64 Linux. I saw one assertion

...Sel and found one issue so far that already got fixed (https://bugs.llvm.org//show_bug.cgi?id=32733). If he finds other correctness issues, I'm sure he'll keep on reporting them. Great!
