EvalAddr - EvalAddr and EvalVal are mutually recursive functions that check if the expression in a return statement evaluates to an address to a location on the stack, a local block, an address of a label, or a reference to local temporary. The recursion is used to traverse the AST of the return expression, with recursion backtracking when we encounter a subexpression that (1) clearly does not lead to one of the above problematic expressions (2) is something we cannot determine leads to a problematic expression based on such local checking.
Both EvalAddr and EvalVal follow through reference variables to evaluate the expression that they point to. Such variables are added to the 'refVars' vector so that we know what the reference variable "trail" was.
EvalAddr processes expressions that are pointers that are used as references (and not L-values). EvalVal handles all other values. At the base case of the recursion is a check for the above problematic expressions.
This implementation handles:
