[cfe-dev] Classify variables of a loop/compound statement/etc.

[LUIS MIGUEL SANCHEZ GARCIA]

Alberto: Thanks for your help.

Maybe you can create a recursive visitor and use the VisitStmt method.

Is there any example code to start?

> What you mean with read/write variables?

I'll explain with a sample:

std::vector<int> A(M);
std::vector<int> B(M);
....
/* Loop to analyze */
for (int i=0; i<M; ++i) {
   A[i] = B[i];
}

I would like to get the following information:

Local: i (rw)
External: A(w),B (r), M(r)

where *r* means that the variable is read into the code, and *w* means that
the variable is modified (in someway)

Regards,
Luis.
