下面这段代码，如果分别在大端和小端机上运行，结果会有什么差异呢？
static WORD32 F(WORD32 data, WORD32 key)
{
WORD32 t;
BYTE v[4], u;
/* Key Insersion */
t = data+key;
/* Secret Constant */
v[3] = (BYTE)((t>>24)&0xff);
v[2] = (BYTE)((t>>16)&0xff);
v[1] = (BYTE)((t>> 8)&0xff);
v[0] = SecretConstant[t&0xff];
u = v[0]^0x65; v[1] ^= lrot8(u,1);
u = v[0]^0x2b; v[2] ^= lrot8(u,5);
u = v[0]^0xc9; v[3] ^= lrot8(u,2);
/* Rotate */
t = ((WORD32)v[3]<<24)|((WORD32)v[2]<<16)|((WORD32)v[1]<<8)|(WORD32)v[0];
t ^= lrot32(t,9) ^ lrot32(t,22);
return t;
}
