从 CPU 角度理解 Go 中的结构体内存对齐
大家好，我是 Go 学堂的渔夫子。今天跟大家聊聊结构体字段内存对齐相关的知识点。

原文链接： https://mp.weixin.qq.com/s/H3399AYE1MjaDRSllhaPrw

大家在写 Go 时有没有注意过，一个 struct 所占的空间不见得等于各个字段加起来的空间之和，甚至有时候把字段的顺序调整一下，struct 的所占空间又有不同的结果。

本文就从 cpu 读取内存的角度来谈谈内存对齐的原理。

01 结构体字段对齐示例

我们先从一个示例开始。T1 结构体，共有 3 个字段，类型分别为 int8,int64,int32。所以变量 t1 所属的类型占用的空间应该是 1+8+4=13 字节。但运行程序后，实际上是 24 字节。和我们计算的 13 字节不一样啊。如果我们把该结构体的字段调整成 T2 那样，结果是 16 字节。但和 13 字节还是不一样。这是为什么呢？

type T1 struct {

f1 int8  // 1 byte
f2 int64 // ... ⌘ [Read more](https://gocn.vip/topics/20967)```
