I have a code which forms the infrastructure for some reliability analysis.
I have put that code into a separate folder in the "m5/src/avf" directory
and
have added a SConscript file into "avf" folder with the following content:
Import('*')
SimObject('RelObj.py')
SimObject('PreDeadBuffer.py')
SimObject('AvfPredictor.py')
Source('reliability.cc')
Source('rel_counter.cc')
Source('dyn_dead.cc')
Source('avf_predictor.cc')
I have also modified some files/structures in the CPU such as
InstructionQueue and ROB. My goal is to analyze some behavior in these
structures. So, I have modified some functions, e.g. Tick(), to send
information to the analysis infrastructure through its API.
Any clue about the problem? Is adding the SConscript file all I have to do
to add new code/functionality to M5?
Part of the compilation output is as follows:
