Hi Haseung, In Arm FP registers share the same storage with SIMD (Vector) registers, so we usually refer to them as SIMD&FP registers. This is why in gem5 we don’t use the floating point register type and we use the vector type only

LBM is an FP workload, and the simulation shows that "system.switch_cpus.commit.floating" is zero in stats.txt. As a result of a little search, it was confirmed that instructions such as fadd and fsub were classified as 'isVector'. I wonder why fadd is not 'isFloating' but 'isVector'. And when classified like this, is there any possibility of simulation error in inst_queue or fu_pool? If you know, please reply.
