First I use LLVM PASS to extract all of the functions from the LLVM bitcode that compiled by `gollvm`. What I got is as follows:

```

github_0com_1emitter_x2dio_1emitter_1internal_1security_1cipher._64_7uint8..eq
github_0com_1emitter_x2dio_1emitter_1internal_1security_1cipher._664_7uint8..eq
github_0com_1emitter_x2dio_1emitter_1internal_1security_1cipher..import
github_0com_1emitter_x2dio_1emitter_1internal_1security_1license.New
github_0com_1emitter_x2dio_1emitter_1internal_1security_1license.NewV3
github_0com_1emitter_x2dio_1emitter_1internal_1security_1license.V3.NewMasterKey
github_0com_1emitter_x2dio_1emitter_1internal_1security_1license.V3.Cipher
github_0com_1emitter_x2dio_1emitter_1internal_1security_1license.V3.String
github_0com_1emitter_x2dio_1emitter_1internal_1security_1license.V3.Contract
github_0com_1emitter_x2dio_1emitter_1internal_1security_1license.V3.Master

```

Are there any methods to convert these mangled name to the form in golang like `func Register(name string, i vlauth.IFace) error`. Or `func Register() xxx` to mangled name. Any help would be much appreciated!

I don't think there is any existing program that will do it for you,
but the relevant code is

Oh, thanks! I will rewrite that.
