[gem5-users] Understanding Squashed Loads/Stores

[Arth Shah via gem5-users]

Hi everyone,

I'm running a benchmark on the O3CPU model (aarch64) and see something
strange that I wasn't able to understand. I see a lot of Squashed loads and
stores in the LSQ but it doesn't seem like it is due to
branch misprediction or Cache blockages. What else could cause this
magnitude of squashes in LSQ?

cpu.lsq0.squashedLoads       657977
cpu.lsq0.squashedStores      1386633

cpu.lsq0.blockedByCache            0
cpu.iew.branchMispredicts           31

Thanks,
Arth
