Cool, what are you teaching? Intro to RISC-V assembly programming or some CPU architecture class?
Yeah about the shift, I am not sure what happened. I actually probably wanted to remove mention of the shift, and forgot to do it for BLTU.
I think for my cheat sheet I was aiming for more of a device to jog your memory rather than a completely accurate description given that some of the instructions actually require quite an elaborate description.
It is a bit hard to find the right balance when making these kinds of cheat sheets. The official one doesn't even describe what the instructions do. Personally I found that impractical which is why I wanted to make my own.
