Obscure names

[Nitin Gupta]

sr and dr are source register and target registers
src1 and src2 are sources for various functional units

You are not required to use the same names, If you are using *.cpu as an
skeleton for your own port.

I will suggest that if you are not sure of any variable defined in xyz.cpu,
try to see its usage in xyz.c. Or just use a source browsing tool like CSCOPE.
