Hi. So....if I want to intercept ALL message sends....going to #normalSend is not enough since I have #class, #==, Float>>#+   etc that are executed directly like bytecodes. So...my questions are now:

1) Those special selectors are those that are in "Smalltalk specialSelectors" ?  are there more?  all from there are special?

2) All those "Smalltalk specialSelectors"  have their associated bytecode primitive in Interpreter??  If true, then I should modify all bytecodePrim*  in Interpreter. I am right?   If I do that, that's all ? I am intercepting everything?

Right.  Just modify all of them to eliminate the optimized code and to revert to normalSend.  

Thanks Eliot. I didn't understand. What is the optimized code?   I checked all bytecodePrim* and the ones that DO NOT send "self normalSend" at the end, are very few. The problem is that some return before returning "self normalSend". So...I should modify all those who DO NOT call "self normalSend" at the end and those which return before.

 
Providing you also look at the perform and method evaluation primitives I think you'll get all sends. 


#primitivePerform*   and #primitiveExecuteMethod*    ???
   
There is another way.  Modify the Smalltalk compiler to to use the special selector sends.


Thanks Eliot for the idea. Can you explain me a little more (sorry, newbie here!). You mean that with the Compiler I can do that all method sends use the normal send instead of special bytecodes or primitives?

Thank you very much.

Thanks a lot in advance,

    Sure, I'd be happy to discuss it.
