First of all, thanx all for all your help, I'm finally seeing the  
light at the end of this long tunnel ;-)

You're right, the load was moved to the outer loop...

I still have 2 more questions :

- How can I get the address of the load in question and pass it to the  
function. I've looked around in the code but haven't found anything  
similar. DR_MEMTAG seems to give an alias but how can I use that ?

- I am currently working on loop modification, is it difficult to  
expand to the whole program, thus looking at each loop and at what  
level should I include my PASS in the passes.c file ?
