Hi all,

At the EuroLLVM BoF people asked where the design discussions around
GlobalISel take place. Naturally, a lot of them take place at Apple,
since they have the highest density of co-located GlobalISel devs, but
we also have some in Phab.

For those of you that are interested, please have a look at the
following topics - discussions are progressing rather slowly and we
definitely wouldn't mind some more involvement from the community:

Legalization of non-power-of-2 types:

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:

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 be useful, we could also try to send a
weekly-ish email listing the pending reviews and any points that need
coordination. We're open to any suggestions on how we can communicate

Diana (with inputs from Kristof and Quentin)
