xNextInt: unnecessary if branch?

[arnaud-ma]

Here:

cubiomes/rng.h

Lines 214 to 225 in e61f905

	static inline int xNextInt(Xoroshiro *xr, uint32_t n)
	{
	uint64_t r = (xNextLong(xr) & 0xFFFFFFFF) * n;
	if ((uint32_t)r < n)
	{
	while ((uint32_t)r < (~n + 1) % n)
	{
	r = (xNextLong(xr) & 0xFFFFFFFF) * n;
	}
	}
	return r >> 32;
	}

The condition ((uint32_t)r < (~n + 1) % n) will never be true because (~n + 1) % n simplifies to 0 for any value of n.
