Sorry for the confusion. I was looking in $src/cpu and you're referring 
to $src/cgen/cpu. These separate directories exist due to licensing and 
copyright issues specific to the projects for which these ports were 
created.

You are right that some of the .cpu ports do not seems to have 
corresponding .opc files. It could be that the tools created by CGEN 
from these do not require it. The .opc file is used to generate elements 
the opcodes library for each port.
