The functionality of the new CMP.condn.fmt is the following one: If the comparison specified by the condn field of the instruction is true for the operand values, the result is true; otherwise, the result is false. If no exception is taken, the result is written into FPR fd; true is all 1s and false is all 0s repeated the operand width of fmt. All other bits beyond the operand width fmt are UNPREDICTABLE.
