Dave,
Thanks for the quick response! I will create a minimal opc file for now,
but your response has me puzzled. In the 2 CVS trees where I have
looked(cgen and sid) there are several cpu's without .opc files.
Specifically, arm, ia32, sh and I do not see the cris.cpu.
I am a little new to this so I must be doing something fundamentally
wrong... I would appreciate any light you can shed on my situation...
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.
