If the mask is checked with the highest bit... I mean, if you compute the
mask with:
/* maskm = ((1 << cnt) - 1) | 1 */
maskm = GMP_NUMB_MASK >> (GMP_NUMB_BITS - MAX (cnt , 1));
#ifndef NO_MASK_ADJUST
maskm = (maskm << (ucnt != 0)) | 1;
maskm >>= ((ucnt != 0) & (cnt != GMP_NUMB_BITS)
& (up[n - 1] < (vp[n - 1] + 1) * (m & maskm)));
#endif
m &= maskm;
Then you get
bits/iteration avg: 2.71
Ĝis,
m
