[cfe-dev] Array index detection

[moataz ragab]

I would like to detect the index expression of single or multi-dimensional
arrays.
I wrote the code below to accomplish this and wanted to check if there is a
better way to find the index expression(s).
if there is an expression like this : a[i][j][z]. The code below will find
the indices in the following order z, j, then i

          Expr *Curr = LHS;
          ArraySubscriptExpr *ASE;
          while(ASE=dyn_cast<ArraySubscriptExpr>(Curr)) {
            Expr *Idx  = ASE->getIdx();
            *Out<<"Index Expr is:";
            Idx->dump();
            Curr = ASE->getBase();
            if(ImplicitCastExpr *ICE = dyn_cast<ImplicitCastExpr>(Curr)) {
              Curr = ICE->getSubExpr();
            }
            *Out<<"Base Expr is:";
            Curr->dump();
          }

Thanks,
Moataz
