> There are some tests for 64bit reductions. We will probably want to enable inloop reductions for them in the future too, as we have the instructions. That will require a lot of costmodel improvements though.

Ah, okay, I thought it was related to not having (much) i64 instructions. Perhaps worth adding your remark as a comment to that check.
