Yay! It works beautifully :D
I added this method in CompiledMethod as an extension of my project:
CompiledMethod>>referredInstVars
|theClass idx|
theClass := self methodClass.
^theClass instVarNames select: [ :varName |
idx := theClass instVarIndexFor: varName.
(self readsField: idx) or: [ self writesField: idx ]
]
