Summary

• Black line represents compile path
• Blue line represents runtime call-path

Compile Path

1. Compile interface symbol from source (*.jar for Java, *.dll for C#, etc...)
2. Generate bridge from interface symbol

Call Path

1. Host calls bridge
2. Bridge calls wrapper stub
3. Wrapper calls language-specific runtime
4. Runtime calls source

Exempli gratia

For example (Use C# on C++):

However, Native languages (such as C++) doesn't have language-specific runtime:

Compilation Process

• Additional attributes describing Object-Oriented information (such as 'which class owns this function') required
  • That's because LLVM IR does not support OOP model

Bidirectional Linkage

• Black line represents compile path
• Blue/Green line represents runtime call-path
• Red line represents runtime load-path(such as dlopen or LoadLibrary)

With this model, each language can be linked on one process(Init Process in this diagram).
