I used the api get_var_uses which only can be received as variable.Variable type,but var_3290 is MediumLevelILVar,called this api will got error!

get_var_uses
    var_data = var.to_BNVariable()
AttributeError: 'MediumLevelILVar' object has no attribute 'to_BNVariable'

How can i do like binary ninja cross reference behavior? thanks.

To get the var_x3290 variable's cross reference like above.

Answer 1

Try get_var_uses and get_var_definitions with MediumLevelILVar type data's src method like this:

    var=None
    if isinstance(state_var,MediumLevelILVar):
        var = state_var.src
    else:
        var = state_var

state_var as a MediumLevelILVar type data.
