RHO

#define RHO	(		b,
			a,
			n,
			c
	)

Value:

{ \
   b = t[(a[n] >> 56) & 0xFF]; \
   b ^= ROR64(t[(a[(n + 7) % 8] >> 48) & 0xFF], 8); \
   b ^= ROR64(t[(a[(n + 6) % 8] >> 40) & 0xFF], 16); \
   b ^= ROR64(t[(a[(n + 5) % 8] >> 32) & 0xFF], 24); \
   b ^= ROR64(t[(a[(n + 4) % 8] >> 24) & 0xFF], 32); \
   b ^= ROR64(t[(a[(n + 3) % 8] >> 16) & 0xFF], 40); \
   b ^= ROR64(t[(a[(n + 2) % 8] >> 8) & 0xFF], 48); \
   b ^= ROR64(t[a[(n + 1) % 8] & 0xFF], 56); \
