set_user_var_value(var: Variable, def_addr: int, value: PossibleValueSet) → None[source]

set_user_var_value allows the user to specify a PossibleValueSet value for an MLIL variable at its definition site.

Warning

Setting the variable value, triggers a reanalysis of the function and allows the dataflow to compute and propagate values which depend on the current variable. This implies that branch conditions whose values can be determined statically will be computed, leading to potential branch elimination at the HLIL layer.

Parameters:

  • var (Variable) – Variable for which the value is to be set

  • def_addr (int) – Address of the definition site of the variable

  • value (PossibleValueSet) – Informed value of the variable

Return type:

None

Example:
>>> mlil_var = current_mlil[0].operands[0]
>>> def_address = 0x40108d
>>> var_value = PossibleValueSet.constant(5)
>>> current_function.set_user_var_value(mlil_var, def_address, var_value)
split_var(var: Variable) → None[source]

split_var splits a varible at the definition site. The given var must be the variable unique to the definition and should be obtained by using MediumLevelILInstruction.get_split_var_for_definition at the definition site.

This function is not meant to split variables that have been previously merged. Use unmerge_vars to split previously merged variables.

Warning

Binary Ninja automatically splits all variables that the analysis determines to be safely splittable. Splitting a variable manually with split_var can cause IL and decompilation to be incorrect. There are some patterns where variables can be safely split semantically but analysis cannot determine that it is safe. This function is provided to allow variable splitting to be performed in these cases by plugins or by the user.

Parameters:

var (Variable) – variable to split

Return type:

None

unmerge_vars(target: Variable, sources: Union[List[Variable], Variable]) → None[source]

unmerge_vars undoes variable merging performed with merge_vars. The variables in sources will no longer be merged into the target variable.

Parameters:
Return type:

None
