Assembly Programming Tutorial 函数调用之堆栈原理（二） C/C++内存对齐详解 Data Alignment 关于内存对齐，看我 What is data alignment? - WolfSound memory alignment what: 将数据排列在特定内存位置，以加快cpu访问数据的速度 a way of arranging data in memory so that it can be accessed faster by the processo why： cpu 按照 word(32bit and 64bit)读取数据，如果不按照特定的位置排列好数据， 一个数据耗费更多次cpu时间去读取 example: alignment non-alignment how to alignment primitive type 放置在特地位置 short: 2 bytes (aligned to even addresses) short：2 字节（与偶数地址对齐） int: 4 bytes (aligned to addresses divisible by 4) int：4字节（对齐到可被4整除的地址） non-primitive add padding: 插入填充字节
