F2FP or Uf2FP? #103

Hi, Using opcode tool on 3080, I see an instruction named F2FP as below:

kernel 5 - void bert::skiplnDQQ<128, 8, false>(int, signed char const*, signed char const*, signed char*, __half const*, __half const*, __half const*, float, float, float) - #thread-blocks 196608,  kernel instructions 157286400, total instructions 1819459844
...
  F2FP.PACK_AB = 9437184
...

In the reference manual, there is no F2FP, but in fact there is an instruction called UF2FP. So, I am wondering are these instructions the same? Is there a reason for the name change?
