NAME
       usubBorrow - subtract unsigned integers and generate borrow


DECLARATION
       genUType usubBorrow(genUType x, genUType y, out genUType borrow);


PARAMETERS
       x
           Specifies the first vector to be used in the subtraction operation.

       y
           Specifies the second vector to be used in the subtraction operation.

       borrow
           Specifies the variable to receive the borrow output of the difference.


DESCRIPTION
       usubBorrow subtracts two 32-bit unsigned integer variables (scalars or vectors) and
       generates a 32-bit unsigned integer result, along with a borrow output. The result is the
       difference of x and y if non-negative, or 232 plus that difference otherwise. The value
       borrow is set to 0 if x ≥ y and to 1 otherwise.
