Hi, Mariano.
I don't understand, why you need to dive into specific primitive(s),
while you can simply place a hook before entering any primitive
is there a way to do this in a genera way or I need to do it manually
for each primitive?
FWIW, it's questions like these that make people wonder if you've done your homework.
Is it so hard to answer in a ploite way??
If you read my first line of the email says "Hi. Sorry if the question is newbie. I am still reading the blue book,
so in case this is explained there I would just appreciate a link to it.
"
is it really hard to understand and simply answer page 620 ?
Anyway, those were not my original questions.
Thanks
Mariano
The precise question is answered on page 620 of the blue book.

and
mark all objects, which passed as parameters
(receiver & args) as 'used', and then call primitive function?
The problem is that not all of them are "used" in all primitives. Just
as an example, #bytecodeNew:
bytecodePrimNew
messageSelector := self specialSelector: 28.
argumentCount := 0.
self normalSend.
I don't want to trace the receiver there, but it is really not used
there. I will trace it in #normalSend.
Or sometimes a primitive fails because one of the arguments is more than
32bits or because it is not smallInteger or whatever...I don't want to
mark them as used just for being a parameter. I want to mark them when
they are really used by the VM.
I want to avoid as much as overhead as possible.
Right now I put the tracing in #normalSend, but then I modifed some
bytecodes like those for #class or #== since they were not going
throught normal send.
Thanks
