Thanks. To solve this problem, i implement TraverseForStmt below:
   
     virtual bool TraverseForStmt(ForStmt *s) {
        if (!WalkUpFromForStmt(s))
            return false;
        m_inForLine = true;
        for (Stmt::child_range range = s->children(); range; ++range) {
            if (*range == s->getBody())
                m_inForLine = false;
            TraverseStmt(*range);
        }
        return true;
    }

Careful with this; the body of a for-statement is also within the for statement:


for (int i = 0; i < 10; ++i) {
  ++i, --i;
}


Not familiar with the RecursiveASTVisitor traversal, so I can't tell you exactly how to do it. Maybe you already got this correct.
