RND

#define RND	(		a,
			b,
			c,
			d,
			e,
			f,
			g,
			h,
			k
	)

Value:

t0 = h + S1(e) + Ch(e, f, g) + k;               \
        t1 = S0(a) + Maj(a, b, c);                      \
        d += t0;                                        \
        h  = t0 + t1;

RNDr

#define RNDr	(		S,
			W,
			i,
			k
	)

Value:

RND(S[(80 - i) % 8], S[(81 - i) % 8],   \
            S[(82 - i) % 8], S[(83 - i) % 8],   \
            S[(84 - i) % 8], S[(85 - i) % 8],   \
            S[(86 - i) % 8], S[(87 - i) % 8],   \
            W[i] + k)
