I would suggest doing this in the Baseline compiler only, obtaining the information to feed to the Opt compiler when it is invoked. This is similar to the collection of basic block counts done by the Baseline compiler already. Do want to know the specific objects (instances) involved? I am guessing you really just want to know how many times a particular field is accessed. You can actually derive that from the basic block counts if you note which getfield and putfield operations occur in each block. That may be the easiest way. Curiously, I responded just this morning to someone asking about getting basic block counts!
