<div><div>The simplest probably would be finding all relevant loop nodes, i.e. ForExpr-s, identifying the loop induction variable, i.e. the VarDecl-s (if any), and finally running a RecursiveASTVisitor on its body, looking for a DeclRefExpr referring to any of the VarDecl-s you identified in the previous step.<br>

<div>I am interested in knowing if an expression is derived from loop induction variable or not. As of now, I am able to inspect every expression after locating "if" statement in the code.
<br></div>
<div>Assume following code:<br></div>
</div>
<div>for(int i=0;i<32;i++)<br></div>
</div>
<div> i=i+2;<br></div>
<div> </div>
</div>
<div>in above code, I am able to get access to the expression "i+2" but how should I analyze its LHS and RHS for induction variable?<br></div>
<div> </div>
</div>
<div>Any help appreciated. <br></div>
