Clearing out the buffer if we hit an invalid condition

[olgarose]

Do we need to keep track of what we put in the buffer for EA? For OPCODE, I don't but anything into the buffer until I'm sure it's valid... can EA have a valid source and then an invalid destination? We would need to clear out the source then.

I though EA could have a valid source but invalid destination. Are we checking EA before putting into the buffer?

Right now if we hit an invalid condition for EA we branch to INVALID_EA. Can that just clear the buffer and fill it with whatever we're supposed to for garbage commands?
