I like this position--with good kind natured folks arguing over the best
way to help me. ;P
Thank you both.
I took a quick look at Visium, and noticed arithmetic instructions in
the .md file doing a lot of clobbering of the condition codes register.
This doesn't seem very efficient, since it pre

From a 30 second view of your ISA, it appears that most

I would suggest modeling condition code handling similar to how it's
done on the x86 port.
