Move instruction class is missing in nvprof metrics

A class of instructions are known as Move according to the sass instruction set [1], however, there is no nvprof metric for that even in recent nvprof versions. May I know why? Using nvbit, I see a program has a considerable number of Move instructions (thread level).

SEL = 158303666904
SHFL.IDX = 95820990188

The total is 254,124,657,092.
