When doing an unsigned 64 bit division with a divisor that has its most significant bit set, the division code would spill a bit off of the end of a uint64_t trying to shift the dividend into position. This change adds code that handles that case specially by purposefully letting it spill and then going ahead assuming there was a 65th one bit. |
