--- Comment #1 from Michael Nolan <mtnolan2640 at gmail.com> ---
I'm working on defining the pipeline data type for this, and I'm wondering how
I should handle the CR input. Conditional branches can branch on any of the 32
bits in the cr, so I think it should take in the entire CR. However, I suspect
we'll be implementing cr0..cr7 as separate 4 bit registers to avoid false
dependencies, so making the branch take in the whole register would complicate
matters
