--- Comment #7 from Jacob Lifshay <programmerjake at gmail.com> ---
one part that is very useful or required is for the decoder to determine
exactly which registers each instruction reads/writes, instead of doing what we
do (which I think is a major design flaw) where nothing knows exactly what
registers will be written or not until the ALU finishes computing and sets the
output valid flags.
