# 6.5 编译日志

在[Schedule.StaticInit()](/6.-golang-bian-yi-qi-chu-shi-hua-ren-wu/6.4-fu-zhi-yu-ju.md#chu-shi-hua-shi-jian)方法中我们可以看到`base.Flag.Percent`用来控制是否 dump 动态初始化语句，该 Flag 对应的编译参数是`-%`. 将如下代码保存至文件`main.go` 中：

```go
package main

import "unsafe"

// 静态初始化语句
var version = 1.2
var versionAlias = version
var names = []string{"Goalng"}
var nameBytes []byte = []byte("Golang")
var nameSize = unsafe.Sizeof("Golang!") // 此处 unsafe.Sizeof 的代码在编译时执行

// 动态初始化语句
var nextVersion = version + 1
var firstName = names[0]
```

通过命令编译文件`go tool compile -G=3 -%=1 main.go`会得到如下结果：

> ```
> nonstatic [0xc000111d60]
> .   AS tc(1) # main.go:13
> .   .   NAME-main.nextVersion tc(1) Class:PEXTERN Offset:0 float64 # main.go:13
> .   .   ADD tc(1) float64 # main.go:13 float64
> .   .   .   NAME-main.version tc(1) Class:PEXTERN Offset:0 float64 # main.go:7
> .   .   .   LITERAL-1 tc(1) float64 # main.go:13
> nonstatic [0xc000111e50]
> .   AS tc(1) # main.go:14
> .   .   NAME-main.firstName tc(1) Class:PEXTERN Offset:0 string # main.go:14
> .   .   INDEX tc(1) string # main.go:14 string
> .   .   .   NAME-main.names tc(1) Class:PEXTERN Offset:0 SLICE-[]string # main.go:9
> .   .   .   LITERAL-0 tc(1) int # main.go:14
> ```

可以看出`nextVersion`与`firstName`两个赋值语句的初始化需要在运行时进行。
