I used the exitcallback to register a function which is called at the end of
simumations. I use floating point quantities in the simulations and wanted to
print them out in my own format in a file. This function opens a file, dumps
the required values into it at the end of simulation.
This is working perfectly in SE mode. But in the FS mode, there is no file
being generated. The simulation ends (say when i do a ctrl-C) and dumps out
the standard stats,but somehow does not call this exit function.
This is certainly odd. There should be no difference in FS and SE mode
for this stuff.
Python has an atexit handler (in src/python/m5/simulate.py) which calls
internal.core.doExitCleanup upon exiting python. That python call
actually is a wrapper for the c++ function doExitCleanup in
src/sim/core.cc.
I'd suggest putting a breakpoint on doExitCleanup and make sure it's
actually being called. You should also verify that the callback is indeed
making it onto the callback queue.
If that doesn't get you where you need to go, I can try and see if I can
reproduce the bug on my machine.
