Subject: [gem5-users] Assistance Required - Assertion Failure in RegFile

Dear gem5 Community,

I am currently using the gem5 simulator version 22.1.0.0, compiled on June 14, 2023, for my research work and I have encountered an issue that I need help with.

During the simulation, the program aborts with an assertion failure in the register file. The error message is:

cCopy code

gem5.opt: build/ARM/cpu/regfile.hh:75: const Reg& gem5::RegFile::reg(size_t) const [with Reg = long unsigned int; size_t = long unsigned int]: Assertion `sizeof(Reg) == _regBytes && idx < _size' failed. Program aborted at tick 94517000

The command that I used to run the simulation is:

bashCopy code

./build/ARM/gem5.opt --debug-flags=MinorExecuteOp --debug-file=fadd1.txt configs/example/arm/starter_se.py --cpu="hpi" --num-cores=1 "/home/david1136/ARM/se-benchmarks/FloatMM"

I have tried to diagnose the problem myself, but I haven't been able to identify the root cause. I believe this issue might be related to an incorrect register access, although I am not entirely certain. I have checked my configuration and my setup, and everything appears to be correct.

Could you provide me with some guidance on how to troubleshoot this problem, or indicate whether this is a known issue that could be resolved with a patch or an update to the gem5 version I am using?

Any help you can provide would be greatly appreciated.
