L�der,

you can do something like:

class := myCompiledMethod methodClass.
class instVarNames select: [ :varName |
�� idx := class instVarIndexFor: varName.
�� myCompiledMethod readsField: idx or: [ myCompiledMethod writesField: idx ]
]

because #readsField: and #writesField: are index based.

You can also see as an example: Behavior>>#whichSelectorsAccess:� that is var named based, but over all class selectors.

Hi!
I'm playing with some metaprogramming, and I'm stuck at trying to find out which instance variables are referred inside a method.
I've found that a CompiledMethod understands hasInstVarRefs, but I don't recognize a method that could tell just me what I'm looking for.

Any leads?

Thanks!
Carla.
