go语言编译
2021/7/7 6:06:32
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
