Resolve GCC Warning and Address Potential Bug in Checkpoint Functionality #279
@aamodt @deval281shah
We are currently working on minimizing the number of gcc warnings in gpgpusim. During our review, we encountered a specific line of code where the contents of a register are being dumped. However, the problem we encountered is that the union used in this line has the potential to hold data larger than an unsigned long long. which might lead to issues when the checkpoint is used.

However, the problem we encountered is that the union used in this line has the potential to hold data larger than an unsigned long long. which might lead to issues when the checkpoint is used.
To address this issue, we believe it would be beneficial to modify the code and adopt a similar approach to the print_reg function in the ptx_sim.cc file of the gpgpu-sim_distribution repository. You can find the relevant code snippet at this link: https://github.com/gpgpu-sim/gpgpu-sim_distribution/blob/90ec3399763d7c8512cfe7dc193473086c38ca38/src/cuda-sim/ptx_sim.cc#L331.
