OK, I see what you are doing. Basically, if a pseudo maps onto a real
register somewhere in the regcache, you return the address of that.
However, what should be done if the pseudo doesn't exist as a single
entry, or if it is a manipulation of a real register? For example, on the
ARM, the CPSR may be just a few bits retrieved from the PC.
Also, what would you do if you needed to address two non-adjacent
registers?
R.
