10 // It uses big endian order, which is the same as the
11 // network byte order, unlike x86 systems.
12 // Use OPTIMIZE(2)or higher so that automatic variables get shared
13 // between functions, to stay within the 256 bytes idata space
14 // 它使用大的 endian 命令, 是相同於那网络字节命令,不像 x86 系统。
15 // 使用最佳化 (2) 或更高地所以 自动变量 在功能之间分享,
16 // 停留在 256 个字节 idata 空间里面
