80 to testing whether *any of the four* bytes in longword1 is zero.
83 ((longword1 - repeated_one) & ~longword1) & (repeated_one << 7).
86 2. & ~longword1.
89 - If a byte of longword1 is zero, step 1 and 2 transform it into 0xff,
92 - If a byte of longword1 is nonzero, let its lowest 1 bit be at
97 So, if longword1 has only non-zero bytes, tmp is zero.
98 Whereas if longword1 has a zero byte, call j the position of the least
104 The test whether any byte in longword1 is zero is equivalent
115 longword longword1 = *longword_ptr ^ repeated_c;
117 if ((((longword1 - repeated_one) & ~longword1)
