hummm, we are still using the old mode for condition code handling. From 
what you're saying we need to use the new CCmode. I was looking at the 
internal documents and even though it doesn't seem required to have a 
hard register to keep the condition codes, it is also hard to know how 
it is actually implemented. Is there any port which doesn't have a hard 
register representing a condition code, which used CCMode?
