“go build-buildmode=c-shared”编译的dll，如何隐藏导出的goruntime函数？

使用dumpbin查看导出函数，我发现很多goruntime函数导出，希望能隐藏它们

例如：

// file hello.go
package main

// //Needed for build
import "C"

import (
    "fmt"
)

//export SayHello
func SayHello(name string) {
    fmt.Printf("func in Golang SayHello says: Hello, %s!\n", name)
}

//export SayHelloByte
func SayHelloByte(name []byte) {
    fmt.Printf("func in Golang SayHelloByte says: Hello, %s!\n", string(name))
}

//export SayBye
func SayBye() {
    fmt.Println("func in Golang SayBye says: Bye!")
}

func main() {
    // We need the main function to make possible
    // CGO compiler to compile the package as C shared library
}

我只想导出SayHello、SayHelloByte和SayBye函数，而不是导出goruntime函数

我该怎么办？我搜索了几个小时，没有找到找到找到golang的方法

非常感谢。

现在正是针对这个问题提出的。
