[Help-smalltalk] Tracer tool

[Gwenael Casaccio]

Hi,

I'm working on a tool that trace the excecution of the block (I need to know 
all the objects and methods touched by the block and the methodes inside these 
methods). With something like this :

[ blablabla ] trace.

So I want to mark the context with a flag to know if the current context is 
traced or not and in the method send_message I simply look at the flag in the 
current context and store the result or not.

I've looked at the VM code and it seems that the contexts are allocated with 
the method  alloc_stack_context. So in this method I initialise the trace 
variable with 0. But when I'm in the new primitive VMpr_BlockClosure_trace the 
value of the trace variable of the parent context is not 0. Are there others 
place where the context are initialized ?

Cheers,
Gwenael
