My cpu_models.py file got the snippet.
By the way, one "deviation" I did with regards to the steps in
http://m5.eecs.umich.edu/wiki/index.php/Defining_CPU_Models was in the step
m5/src/python/objects/MyCPU.py: Create a python file (e.g. MyCPU.py) so that
your CPU can be recognized as a simulation object. For this example, we will
just use the same code in the SimpleCPU.py file but replace the name
'AtomicSimpleCPU' with 'MyCPU'.
I created a MyCPU.py, but I placed it in m5/src/python/m5/objects, since all
the other Python object files are in there(03CPU.py,, OzoneCPU.py, etc).
There is not even a directory names "objects" under m5/src/python, the
folders under it are m5 and swig. At first I thought this was just an
oversight on the part of the tutorial writers, but could this be the
culprit?
Here are the lines
mycpu_exec.cc 5693
Ra = xc->readIntRegOperand(this, 0);
mycpu_exec.cc 5701
xc->setIntRegOperand(this, 0, final_val);
Actually the errors I included in my initial email was just a snippet of the
very long list of errors(all concerning the invalid use of undefined type
'struct MyCPU').
For the sake of completion, line 64 in static_inst.hh is
class MyCPU;
Again, thanks!
