Hello everyone, I have been using gem5 for simulating an ARM CPU and am trying to assess the impact of adding a tiny amount of instructions to my code (often just one). This led me to finding out the slightly surprising fact (for me at least) that in Syscall Emulation mode, passing my executable to gem5 with a different path (or renaming my executable) affects the number of instructions simulated.
For example: $GEM5/build/ARM/gem5.opt --outdir=test-sim $GEM5/configs/example/se.py <options> -c test And I have 1371 simulated instructions. By simply doing "mv test test2" I then end up with 1402 simulated instructions. I believe this is the expected behaviour, and gem5 is simulating everything up to loading the executable, but is there any way I can eliminate this kind of "noise" (couldn't find a better word) from my execution? As in, let's say, start counting statistics from a given point in my executable, "main" for example? Thanks in advance, Tarcísio
