Hi, Mariano.<br>
<br>
I don't understand, why you need to dive into specific primitive(s),<br>
while you can simply place a hook before entering any primitive<br>
<br>
<br>
is there a way to do this in a genera way or I need to do it manually<br>
for each primitive?<br>

FWIW, it's questions like these that make people wonder if you've done your homework. </blockquote><div><br>Is it so hard to answer in a ploite way??<br><br>If you read my first line of the email says "Hi. Sorry if the question is newbie. I am still reading the blue book,

The precise question is answered on page 620 of the blue book.<br>

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