/**

|
* We test the interface from Wasm compiled code to the Wasm interpreter by
|
|
* building a module with two functions. The external function is called from
|
|
* this test, and will be compiled code. It takes its arguments and passes them
|
|
* on to the internal function, which will be redirected to the interpreter.
|
|
* If the internal function has an i64 parameter, is has to be replaced by two
|
|
* i32 parameters on the external function.
|
|
* The internal function just converts all its arguments to f64, sums them up
|
|
* and returns the sum.
