Hi,
Below is the execution flow of instruction tracer. Hope useful for you.
Flow of InstTracer
cpu/BaseCPU.py
default_tracer = ExeTracer()
tracer = Param.InstTracer(default_tracer, "Instruction tracer")
cpu/simple/base.cc
BaseSimpleCPU::preExecute()
traceData = tracer->getInstRecord(...）
BaseSimpleCPU::postExecute()
traceData->dump()
cpu/exetrace.cc
Trace::ExeTracerRecord::dump()
Trace::ExeTracerRecord::traceInst()
dump instruction information into output (default output: trace-output)
Best regards,
Yongbing Huang

Subject: [gem5-users] Trace file
Hi Everyone,
I have a question about the trace files.
In src/cpu/exetrace.cc, there is a
Trace::ExeTracerRecord::traceInst(StaticInstPtr inst, bool ran)
I know this function is used to print out the trace, but I searched everywhere,
could not find where it is used. I need to know where it is used because I need
to build an interface between gem5 and my own simulator so that instead of
using the trace to drive my simulator, I can directly feed the trace to my
simulator.
Can anyone help me with this problem?
Thanks,
