> Can you add a few more check lines here? e.g. I'm not sure if the interleaving is disabled for the epilogue loop (if not, then it would need a check for a second store), or if this is actually a loop with a back-edge to vec.epilog.vector.body, and what the increment would be. I assume it's `8` given `<8 x i8>`, but it would be good to have a CHECK line for it.
Given the structure is much more complicated with epilogues with the extra checks and so on, I decided it's easiest just to autogenerate the CHECK lines with utils/update_test_checks.py! It's probably useful to show the whole control flow anyway for at least one test.
