        Computes the backwards semantics of the statement, after the semantics of the sub-expressions have been computed. Meta variables from the sub-expressions will be forgotten after this statement returns. By default, this method delegates to fwdTernarySemantics(InterproceduralAnalysis, AnalysisState, SymbolicExpression, SymbolicExpression, SymbolicExpression, StatementStore), as it is fine for most atomic statements. One should redefine this method if a statement's semantics is composed of a series of smaller operations.
        Type Parameters:
        A - the type of AbstractState
        Parameters:
        interprocedural - the interprocedural analysis of the program to analyze
        state - the state where the statement is to be evaluated
        left - the symbolic expression representing the computed value of the first sub-expression of this statement
        middle - the symbolic expression representing the computed value of the second sub-expression of this statement
        right - the symbolic expression representing the computed value of the third sub-expression of this statement
        expressions - the cache where analysis states of intermediate expressions are stored and that can be accessed to query for post-states of parameters expressions
        Returns:
        the AnalysisState representing the abstract result of the execution of this statement
        Throws:
        SemanticException - if something goes wrong during the computation
