I am running a small C program on gem5. Disassembled binary of the program shows a lot of SSE instructions, but simulator's output stats.txt does not show any SIMD operation type committed. On generating the execution trace from gem5, I can see that those SSE instructions are decoded into operations and labelled as FloatAdd or other similar instructions. My question is, how accurate is the labelling of operations in gem5 for x86 ? I mean it seems a bit misleading to see that no SIMD instructions are committed , while the benchmark has some of them.
Thanks
