Hi Amara, We also had some discussions on the SVE side of reductions on the main SVE thread, but this description is much more detailed than we had before. I don't want to discuss specifically about SVE, as the spec is not out yet, but I think we can cover a lot of ground until very close to SVE and do the final step when we get there.

Hi all, During the Nov 2016 dev meeting, we had a hackers’ lab session where we discussed some issues about loop idiom recognition, IR representation and cost modelling. I took an action to write up an RFC about introducing reduction intrinsics to LLVM to represent horizontal operations across vectors. Vector reductions have been discussed in the past before, notably here:

+cc Simon who's also interested in reductions for the any_true, all_true predicate vectors.
