Hi,

Do you know how this change affects the resulting code on average?

I'm seeing a regression in one of our benchmarks, one loop seems to look different after opt and then our backend fails to recognize it as a hardware loop anymore.
I'm not sure if it's possible to make a hardware loop out of this one too, just thought I'd ask if you've seen any major differences in the output?
