[gem5-users] Does gem5 count float multiplications?

[Da Zhang]

Hey guys,

I am trying to add floating point multiplications (so do floating point
dividing and comparing) to the benchmarks as instruments so that I can use
the number of floating point multiplications as a counter for the
benchmarks during simulation. I see there is FloatMult next to FloatAdd, so
I assume it means float multiplication. However, all of my experiments show
0s.
Does gem5 capture number of floating point multiplications? Or was I
looking at the wrong place in the stats file? I also tried floating point
dividing (FloatDiv) and comparing (FloatCmp), but both are always 0s.

best,
Da

Did you look into SimdFloatMult, SimdFloatDiv, and SimdFloatCmp in the
stats and see if there are any numbers listed in there? The operation might
have been executed with sse instruction.

They are also 0s.
