go语言编译

本文主要是介绍go语言编译,对大家解决编程问题具有一定的参考价值,需要的程序猿们随着小编来一起学习吧!

main.go文件

package main

import "fmt"

func main() {
	x,y:=1,2
	x,y=y+1,x+2

	fmt.Println(x,y)

}

编译:
方法一: go tool compile
使用go tool compile -N -l -S main.go生成汇编代码: 会生成main.o

方法二: go build -gcflags -S
使用go build -gcflags -S main.go也可以得到汇编代码:生成main 二进制文件

方法三: go tool objdump
首先先编译程序: go tool compile -N -l main.go,
使用go tool objdump main.o反汇编出代码
或 go tool objdump -s main main.o反汇编特定的函数
