- * BN_window_bits_for_exponent_size -- macro for sliding window mod_exp functions
- *
- *
- * For window size 'w' (w >= 2) and a random 'b' bits exponent,
- * the number of multiplications is a constant plus on average
- *
- *    2^(w-1) + (b-w)/(w+1);
- *
- * here  2^(w-1)  is for precomputing the table (we actually need
- * entries only for windows that have the lowest bit set), and
- * (b-w)/(w+1)  is an approximation for the expected number of
- * w-bit windows, not counting the first one.
- *
- * Thus we should use
- *
- *    w >= 6  if        b > 671
- *     w = 5  if  671 > b > 239
- *     w = 4  if  239 > b >  79
- *     w = 3  if   79 > b >  23
- *    w <= 2  if   23 > b
- *
- * (with draws in between).  Very small exponents are often selected
- * with low Hamming weight, so we use  w = 1  for b <= 23.

- * calculating the upper half of the product placing the result
- * into a general purpose register. Now *if* the compiler supports
