How to force to include javascript function into the generated JS from addToLibrary call?

[YaoMax]

I use emcc compilation parameter --js-library SOME_LIBRARY.JS to add functionality to C/C++ code to interact with JS code.

SOME_LIBRARY.JS contains such code:

addToLibrary(
{

Func1: function Func1(.......)     {    },

Func2: function Func2(.......)
{
    Func1(....);

    ........calls to web application functions here............
}

}

Func1 is not used directly from C/C++ hence it's thrown out by emcc compiler and I need to add it manually in produced JS file after compilation.

How can I force to include this function into the final JS file without manual insert or without calling that from C/C++ to dumb compiler and not throw it out?

ps. I could potentially include Func1() in web application but dont want since it only does the job with the internal stuff of generated JS.

You would add dependency entry for Func2 that includes Func1. Something like Func2__deps: ['$Func1'], You can find lots of examples by looking for __deps in the builtin JS library files.
