Hi,

If I do something like

```julia
using Cxx

cxx"""
double f(double x)
{
    return 2.0*pow(x,4)-3.0*pow(x,3)+2.0*pow(x,2)-x;
}
"""
jf(x) = @cxx f(x)

```

and then do `@code_native jf(2.0)` the code appears to be the code that calls the compiled C function as opposed to the actual compiled C function. Is there a way to view the compiled C function?

Thanks!
