- 9. IWST 2013 @ Annecy9 NativeBoost A language-side and fast FFI implementation
- 10. IWST 2013 @ Annecy10 Language-side • Extensible • Easy to use • noVM code needed • no low-level code (C wrapper) needed
- 11. IWST 2013 @ Annecy11 Fast Transparent generation of Assembly code from the language-side

- 13. IWST 2013 @ Annecy NativeBoost Example 13 char* getenv(const char*)
- 14. IWST 2013 @ Annecy NativeBoost Example 14 Regular Smalltalk method with one argument
- 15. IWST 2013 @ Annecy NativeBoost Example 15 A pragma indicating that #primitiveNativeCall of #NativeBoost plugin should be executed when this method is executed

- 17. IWST 2013 @ Annecy NativeBoost Example 17 types annotation used to generate marshalling code char* getenv(const char*)
- 18. IWST 2013 @ Annecy NativeBoost Example 18 the value to be passed when calling out
- 19. IWST 2013 @ Annecy NativeBoost Example 19 the external library address in which the function is looked up
- 20. IWST 2013 @ Annecy Speed Comparisons 20 • NativeBoost • Alien FFI • C-FFI • LuaJIT • Callouts • Marshalling • Callbacks

- 29. IWST 2013 @ Annecy Insights into NativeBoost Internals 29 NBExample getenv: ‘PATH’
- 30. IWST 2013 @ Annecy NBExample getenv: ‘PATH’ Insights into NativeBoost Internals 30 Virtual Machine (VM) NativeBoost Plugin
- 31. IWST 2013 @ Annecy NBExample getenv: ‘PATH’ Insights into NativeBoost Internals 31 Virtual Machine (VM) NativeBoost Plugin Fail if no native code associated with #getenv:
- 32. IWST 2013 @ Annecy NBExample getenv: ‘PATH’ Insights into NativeBoost Internals 32 Virtual Machine (VM) NativeBoost Plugin 1. generate native code for marshalling, ... 2. associate it with #getenv: 3. restart the method execution
- 33. IWST 2013 @ Annecy Virtual Machine (VM) NativeBoost Plugin Insights into NativeBoost Internals 33 activate the native code associated with #getenv: NBExample getenv: ‘PATH’
- 34. IWST 2013 @ Annecy Conclusion 34 • NativeBoost-FFI is: • Language-side: extensible, high-level code only • Fast compared to other Smalltalk FFI • Needs optimizations on Callbacks but that would require strongVM support
- 35. IWST 2013 @ Annecy Future Work • Improve NativeBoost Callback performance • Reuse Alien’sVM Callback support? • Better integration of NativeBoost with the JIT • Do not leave JIT-mode when activating a NB method 35
