[cfe-dev] How to know whether expression is derived from induction variable?

[Madhur Amilkanthwar]

Hi,
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.
Assume following code:
for(int i=0;i<32;i++)
  i=i+2;

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?

Any help appreciated.
