Hello all:
I have a question regarding instruction/PC tracking with m5. I'm
working with the ARM_SE simple atomic model, and I need to print out a
sequence of instructions at a specific point in the simulation. I can
do that easily enough using the 'IntRegs' and 'Fetch' trace-flags, or
having an inform() statement in the code, but here's where I'm looking
for some thoughts:
I duplicate select instructions in the code with an LLVM pass and I want
to see specific register contents at specific instrutions[PC] in m5 for
a while after an arbitrary point in the simulation. Is there an easy
way to do this so that I can compare the same program
points/instructions [not checkpointing, though] in each run? The way I
see it currently, with duplicated code, the number of simulated
instructions increases, and PC's will be different, so I'm not sure how
to go about this.
Thanks,
Griffin
