[PATCH] D88161: [AArch64] No NEON instructions to support vector of i64 reductions

[Eli Friedman via Phabricator via llvm-commits]

efriedma added a comment.

> v2i64 *MAXV currently gives a Cannot select. That makes sense since *MAXP also doesn't support i64.

What happens if someone tries to use llvm.experimental.vector.reduce.smax.v2i64 with this patch?  I guess this change stops us from generating MAXV, but what happens instead?  Can we write a test for that?
