[cfe-dev] Count number of array references

[Gábor Kozár]

Probably easiest to do by deriving from RecursiveASTVisitor and
incrementing your counter by one for each ArraySubscriptExpr. That's
assuming you want to count all 'array[index]' expressions. If you want
to count all references to array-typed variables, it's best to look for
DeclRefExpr-s whose type is an ArrayType. If you also want to find
array references from functions calls, I think you'd better visit all
Expr-s, and check their type for ArrayType.



Hope this helps!

Hi,

How can we count number of array references in a given C code with
clang?

Assume code looks like this,

void main()

{

    int a[10];

    a[5]=a[5]+1;

}



in the above code, number of array references are 2.
