[cfe-dev] I can't get the defined size

[Rajendra]

I am also looking to get defined size of array.

Using VisitDeclStmt(Stmt *s), I can get following info:
   Found DeclStmt 
        decl statement: int dummy[5]
        identifier name = dummy
        type = int [5] 

But how to get defined size? 

Also using, VisitBinAssign(BinaryOperator *E) and
VisitArraySubscriptExpr(ArraySubscriptExpr* S), I can get following info:
    Found BinaryOperator
        Assignment Op =  in B1
        IntegerLiteral:
        RHS value: 10

        found array subscript expr
        ImplicitCastExpr:
        ArrayToPointerDecay
        identifier = arr
        IntegerLiteral:
        index value: 9

But why I am getting RHS first for arr[9] = 10;? I should get first LHS
arr[9] and then RHS value 10, since Visit methods are called in pre-order
DFS manner as AST is traverse. Correct me if it is otherwise?

I am having same trouble when I have unary minus on LHS of a binary
operation (e.g. x = -1 + x;), then VisitUnaryMinus() is getting visited
after RHS? why it is so?
